Spring in the Pineywoods

Kentucky Lady’s Slippers – A Gift of Spring

As I sit here typing, we are in the height of August, which has the misfortune of traditionally being our most miserable month – at least climatically speaking.  So as the dried grass crunches beneath my feet and my skin bakes under triple digit temperatures, it’s easy to escape back to a day over four months ago.

It was the last day of March.  There was a definite chill in the air as I set out into the forest.  The gray of dawn was made darker by the the canopy of beech and oak towering one hundred feet above my head.  I worried for a moment that I may not see them – my elusive botanical quarry.  But despite the dim light of the understory, the yellow egg-sized blooms of the Kentucky Lady’s Slipper (Cypripedium kentuckiense) caught my eye like a beacon sent out to some wayfaring sailor, and drew me to them with a siren’s song of its enigmatic beauty.

A few days prior my friend Peter Loos had called and told me that the slippers were out early this year, a full two weeks early.  He also told me that one population, which typically has only a plant or two in flower, was displaying six perfect blooms this year.  If it weren’t for his call, I would have likely missed out on a very special experience.

The soil was cold and damp as I sat, saturated from a previous day’s rain.  It was still to early for photography, the forest too dark to properly render the color of the scene.  So I sat and waited in the company of the forest.  I admired the slippers and the ferns that grew around them.  I listen to the familiar songs of Red-eyed Vireos, Summer Tanagers and Hooded Warblers, and the distant trill of a Northern Parula.  After some time I could see hints of dappled sun in the highest leaves in the canopy.  The forest grew brighter, its colors warmed.  In this new light I could see distant azalea blooms lining the creek downslope.

I had to pay close attention to the light.  There would only be a brief moment for me to capture the image I was after.  That time when the ambient light early morning sun illuminated the forest, but before its rays penetrated the canopy, casting sun spots and uneven light on the forest floor.  Finally the moment was right, and I captured the image above.

Though the end of March may have been the height of the season, spring itself had begun nearly two months prior, when the first of the spring ephemerals pushed their way through the leaf litter.  Perhaps my favorite of these is the Bloodroot (Sanguinaria canadensis), so named for the red sap of its roots that has long been used for a wide range of medicinal purposes.  Bloodroot is now rare in Texas, where it hold on in a few remnant patches of mature hardwood forest.

IMG_5185

Bloodroot – An Ode to Spring

Like the Bloodroot, the White Trout Lily (Erythronium albidum) is one of our first harbingers of spring.  White Trout Lily can be found throughout the Pineywoods.  Though it is common nowhere, it is more frequently encountered in the northern and western portions of this forested ecoregion.  Elsewhere in the state it can be found in some Post Oak Savannah and Cross Timber woodlands.

It is not just the rich woods that experience a flush in early spring activity.  In mid February the wetland pine savannahs of East Texas appear bleak, their grasses turned brown by the short days and biting cold of winter.  But it is in that time that the Woolly Sunbonnet (Chaptalia tomentosa) emerges, opening its blooms in the midday sun.

IMG_4921

Woolly Sunbonnet

Though the forest floor may be coming to life, early spring still finds the trees leafless and dreary.  I captured the haunting scene below as a fog rolled in over the Angelina River on a cold day in mid February.

IMG_4637

The Angelina River looks to be a dismal place in early spring.

Even in early March the forest still seems gripped in winter.  At least from a distance…

But closer examination shows that by early March the forest has come alive.  The scene below was captured at our friends Susan and Viron’s land.  Under their stewardship, a spectacular patch of rich mesic forest has persisted.  Here nearly all of the plants that have become exceedingly rare elsewhere in the states, still thrive.  Their forest contains colonies of Yellow Trout Lily (Erythronium rostratum) that cover acres!

Their land is also home to one of only two known populations of False Rue Anemone (Enemion biternatum) in the state.

IMG_6229

Spring Beauties (Claytonia virginica) flourish here as well.  They are one of our most common spring ephemeral, but that in no way diminishes their beauty.

IMG_6248

Spring Beauty

One of the more unexpected denizens of early spring is the Wrinkled Festive Tiger Beetle (Cicindela scutellaris rugata).  Unlike most tiger beetles, which are most active during the summer, the Wrinkled Festive Tiger Beetle is active in the early spring, and by late May are almost impossible to find.

IMG_6089

Wrinkled Festive Tiger Beetle

This jewel-like beetle is restricted to eastern Texas, western Louisiana, and extreme southwestern Arkansas and southeastern Louisiana. Here it occurs in areas with vast expanses of bare sand such as xeric sandhills and sand “blowouts” in the Pineywoods and Post Oak Savannah.

IMG_6099

Wrinkled Festive Tiger Beetle

By mid-March most of the woodlands in the southern Pineywoods had begun to leaf-out.  The scene below was captured in a vast floodplain adjacent Big Sandy Creek in the Big Thicket.

IMG_6062

Vernal

As the freshly emerging leaves hardwoods begin to turn the slopes and floodplains green, a different explosion of color is occurring in a precious few longleaf pine savannahs in the Big Thicket.  At the few sites where it still occurs, the Federally Endangered Texas Trailing Phlox (Phlox nivalis ssp. texensis) reaches peak bloom in mid-March.

IMG_2597

Texas Trailing Phlox

Around the same time, a very different phlox species blooms in the shade American Beech and other hardwoods of rich forested slopes.  Though common throughout much of its range in eastern North America, Wild Blue Phlox (Phlox divaricata) is rare in Texas.  The combination of pale blue blooms, feathery fern fronds and a gnarly old hornbeam created a scene that seemed like something more suited for a Tolkien novel than the Pineywoods.

IMG_2690

Mirkwood

While we’re on the topic of phlox, one can’t drive the backroads of the Big Thicket without admiring the recently described Texas endemic Big Thicket Phlox (Phlox pulcherrima), a member of the Phlox pilosa complex.

IMG_2734

Big Thicket Phlox

With March in full swing, color was coming to all of the vegetative communities of the Pineywoods.  Wright’s Lily (Schoenolirion wrightii), a rare species of glades and barrens came into bloom over deposits of Catahoula Sandstone.

IMG_2666

Wright’s Lily

And expansive drifts of Wild Hyacinth (Camassia scilloides) turned the forest floor blue in this woodland in the northern Pineywoods.

IMG_2625

Rebirth

One afternoon, as we were exploring the longleaf pine savannahs of the Angelina National Forest, Carolina spotted a splash of yellow in the distance.  It turned out to be a small flatwoods pond decorated with the blooms of thousands of Floating Bladderworts (Utricularia radiata).  These plants are carnivorous, and I couldn’t help but think that below the surface was something akin to a minefield for the unfortunate aquatic invertebrates that dwell within.

IMG_2744

Floating Bladderworts – Minefield

Not all of spring’s palate is painted on the forest floor however, and a multitude of trees and shrubs put on an impressive display as they come into flower.  In the picture below White Fringetree (Chionanthus virginicus) flowers in the foreground while Flowering Dogwood (Cornus florida) blooms in the distance.

IMG_2764

White Fringetree – Old Man of the Woods

By late March the Mayapples (Podophyllum peltatum) have taken over the forest floor.  One of my favorite spring ephemerals, Mayapple is still quite easy to find in certain parts of East Texas, unlike so many other species of rich woods that have become increasingly rare.

IMG_2801

Mayapple – Sea of Green

The large umbrella-shaped leaves of Mayapple are actually toxic.  Only the ripe fruit is edible.  The downy white blooms hang beneath the leaves.  Non-blooming plants always sport a single leaf, while those that bloom have two.

IMG_2817

Mayapples

Along the bluffs lining the Angelina River, Carolina and I found a large colony of Wild Comfrey (Cynoglossum virginianum).  These wildflowers, with their downy basal leaves and tiny sky-blue blooms have become quite uncommon in Texas.  They often occur in the company of the Kentucky Lady’s Slipper, and I couldn’t help but wonder of the enigmatic orchid once called these hills home.

IMG_2872

Wild Comfrey Blooms

Another uncommon species often found in the presence of the lady’s slipper is the Bigleaf Snowbell (Styrax grandifolia).  It’s easy to see how this species gets its common name, as thousands of small white blooms may dangle from its branches in early April.

IMG_3006

Bigleaf Snowbell

In the vast floodplain of the Neches River I spotted a large colony of Eastern Bluestar (Amsonia tabernaemontana), and I stood in the flood waters to photograph its delicate blooms in the evening light.

IMG_3166

Every spring I look forward to the emergence of the trilliums.  This year I found this large colony of Sabine River Wakerobin (Trillium gracile) in a rich hardwood forest in Sabine County.

IMG_3598

Sabine River Wakerobin

By mid-April many of the spring ephemerals have already faded, and a new cast of floral characters appears on the scene.  Clasping Milkweed (Asclepias amplexicaulis) emerges from deep sands and displays its bizarre blooms for all the pollinating world to see.

IMG_5627

Clasping Milkweed

Deep in the forest a very different milkweed was blooming.  By mid April the White (A.K.A Redring) Milkweed was beginning to come into flower.

IMG_5374

White Milkweed

The Zigzag Iris (Iris brevicaulis) can be found on the margins of wetlands in the Pineywoods.

IMG_5309

Zigzag Iris

Flowering Dogwood is one of the most familiar small trees of East Texas.  Lesser known are the other species of dogwood that occur here.  This spring we found several Roughleaf Dogwoods (Cornus drummondii) in bloom along a small stream in Houston County.

IMG_5233

Roughleaf Dogwood

The Rose Pogonia (A.K.A. Snakemouth Orchid) (Pogonia ophioglossoides) is always a crowd-pleaser.  I found several blooming in late April with my friend James Childress in a remote seep on private land.

IMG_4995

Rose Pogonia

One evening in April I received a call from my friend, and author of The Wild Orchids of Texas, Joe Liggio.  He told me that while returning home from a long day of botanizing, he spotted an uncommon wildflower along a remote road in Liberty County.  It was the Foxglove Penstemon (Penstemon digitalis).  Shortly after photographing the plants at Joe’s site, I found it growing in similar remoteness in Sabine County.  This penstemon has a fairly broad distribution in the eastern third of the state, occurring in scattered populations in rich, open woodlands and their margins. There is some debate as to whether it is native outside northeast Texas, while others question whether or not its native to the state at all.  The plants that Joe and I discovered were, in my opinion, unlikely candidates for escapees from cultivation.  This leads me to believe that is in fact native to East Texas.

Also in April, my friend Scott Wahlberg and I visited a site in the Big Thicket where last year I was able to track down Wild Blue Lupine (Lupinus perennis).  I went into some detail on this species in a blog post last year, so I won’t say much here, save to mention it’s striking beauty.

IMG_4621

Another species that I pursued last year was the Green Adder’s Mouth (Malaxis unifolia).  Carolina and I found them again this year, and I photographed them to the sound of the thunder of a rapidly approaching storm.

IMG_4331

En-route to photograph the adder’s mouth, we spotted a striking little purple legume flowering alongside the road.  It was a patch of Sampson’s Snakeroot (Orbexilum pedunculatum), a plant I only occasionally encounter in the Pineywoods.

IMG_4307

Sampson’s Snankeroot

Though it’s pushing the limits of late spring and flirting with early summer, late May still has a lot to offer, botanically speaking.  One warm evening in late May, Caro and I drove out to Walker County to photograph the Bush’s Purple Coneflower (Echinacea paradoxa var. neglecta).  This puzzling population was found growing in a calcareous prairie remnant by my friend Eric Keith.  Echinacea paradoxa is a species of coneflower found in the Ozark Plateau and isolated populations in southern Oklahoma and southeast Texas. While typically yellow, E. paradoxa var. neglecta range from pale purple to deep pink.  The population here in southeast Texas is disjunct from other known populations by hundreds of miles.

IMG_7617

So it was that the Spring of 2018 came to a close and gave way to summer.  It was hard to say goodbye to the cool, gray days of Spring, but as a naturalist I find some joy in each of our seasons.  Soon the sun would be blaring, the cicadas would be trilling, and a whole new cast of plants and animals would make themselves known.

April Recap

April was off to a good start.  I managed to check off five species early on, and had high hopes for the rest of the month.  Unfortunately I couldn’t keep up the momentum and was unable to find any of my targets in April’s second half.  I tried to locate Clasping Jewelflower (Streptanthus maculatus), Creeping Bluestar (Amsonia repens) and Texas Lady’s Tresses (Spiranthes brevilabris) at some historic sites with no luck.  I hoped to check some locations in northeast Texas for Tapertip Trillium (Trillium viridescens), Fire Pink (Silene virginica), and Downy Yellow Violet (Viola pubescens), but was unable to make it that way.  I doubt that I’ll get a chance to see these species this year…maybe next year!  The following are the species on my 2017 biodiversity list I was able to find and photograph in April:

Missouri Foxtail Cactus (Escobaria missouriensis)

Nuttall’s Death Camas (Toxicoscordion nuttallii)

Widow’s Cross (Sedum pulchellum)

Blue Lupine (Lupinus perennis)

Green Adder’s Mouth Orchid (Malaxis unifolia)

2017GoalsApr

The following are some interesting observations I made in April:

I’ll start this post like March’s recap, with a giant Saturniid moth.  For me, seeing this Promethea Moth (Callosamia promethea) was one of the most exciting of the year thus far.  The Promethea Moth is a species typical of the rich deciduous forests of the Eastern U.S. Though range maps show it entering extreme eastern Texas, I am aware of few records of its occurrence in the state. I certainly have never seen one.  Pictured is a female. Promethea Moths are sexually dimorphic, with males being much darker. I spent some time photographic her in all of her brilliance, and left her to continue pumping pheromones into the evening air, leaving chemical trails for males to seek her out and propagate future generations.

IMG_3649

Promethea Moth

In April I also found a few new populations of the uncommon Indian Pink (Spigelia marilandica) on the rich deciduous slopes of the Pineywoods.

IMG_4344

Indian Pink

While looking for the Kentucky Lady’s Slipper we came across this attractive Three-toed Box Turtle (Terrapene carolina triunguis).  Most box turtles immediately withdraw into their shells when approached.  This individual was fairly bold and allowed us to approach for some portraits.

Box Turtles have an interesting relationship with Mayapple (Podophyllum peltatum), a spring ephemeral of rich eastern forests.  These terrestrial turtles are the primary dispersal mechanism for Mayapple seeds.  Most parts of the plant are toxic, however the ripe fruits are edible.  While other animals will consume, process, and deposit the seeds; studies have shown that those that have passed through the digestive system of the box turtle have the highest rate of germination.  Indeed, the drooping fruits seem to rest at a perfect height for a hungry box turtle.

While exploring the Big Thicket we came across the uncommon Piedmont Staggerbush (Lyonia mariana).  A member of the heath family (Ericaceae).

IMG_3887

Carolina spotted this White-eyed Vireo (Vireo griseus) dutifully incubating its eggs.

IMG_3932

The Carolina Larkspur (Delphinium carolinianum) is Carolina’s favorite Texas native flower.  Every year we seek them out.  This year we found a large population in a xeric sandhill north of San Augustine.  We also observed several Prairie Milkvines (Matelea cynanchoides), another species typical of these woodlands on deep sands.

IMG_4421

We also spent an afternoon in a Fleming Prairie Remnant, where I photographed the Reflexed or Topeka Coneflower (Echinacea atrorubens), and Prairie Penstemon (Penstemon cobaea), two species that are rare in the Pineywoods.

IMG_4057

I hope to focus on the unique flora and fauna of xeric sandhills and prairie remnants in future blog posts.  As the temperatures warm in May I hope that I will finally be able to check the first animal species off my list, though there are still plenty of plants to seek out, and special places to explore.

 

 

March Recap

Due to a combination of changed plans and other factors, March was not as productive in terms of 2017 biodiversity goal species as I was expecting.  I was able to check off three species:

Yellowroot (Xanthorhiza simplicissima)

Blue Curls (Phacelia congesta)

Claret Cup Cactus (Echinocereus coccineus)

2017GoalsMar

I spent most of the month of March exploring outside my home turf of the Pineywoods.  From the South Texas Plains to the Edward’s Plateau, I observed an incredible diversity of habitats and species, which are highlighted in previous blog posts.  I did however get to spend some time in the field around here.  To follow are some of March’s highlights from East Texas.

This year has been good for Luna Moths (Actias luna).  I observed several freshly emerged males.  Males utilize their feathery antennae to pick up subtle pheromone cues from females and may fly miles to find a mate.  Adult Luna Moths lack feeding mouth parts, and live on average about a week.  As adults they really are driven by a singular purpose: to breed.

IMG_7982

Luna Moth

March is a great time to enjoy flowering trees and shrubs in East Texas.  This year most species put on a decent show.  The Eastern Redbud (Cercis canadensis) seemed to peak in late February, however several were still in flower in early March.

IMG_7011

Eastern Redbud

Among my favorite spring displays is that of the Flowering Dogwood (Cornus florida).  This small tree ranges throughout much of the eastern United States.  To me it is one of the emblematic spring blooms of East Texas.  Christian accounts claim that Jesus was crucified on the wood of a dogwood tree.  Story goes that they were once tall, stately trees that Jesus, following his crucifixion, morphed to their current gnarled form – presumably so no others could ever again be crucified upon their wood. Their “flowers” now appear as crosses each spring around Easter.

In reality the white “flowers” are modified leaves called bracts. The flowers are the yellow structures at the bracts’ centers.  In the late summer the tree will bear red fruits that are cherished by wild turkeys.  I also think that their growth form only lends beauty to this already stunning species.

The Fringetrees (Chionanthus virginicus) seem to hit their peak as the dogwoods are beginning to fade.  Their wispy, whitish green blooms light up the forest edge and the understory in open woods.

IMG_7878

Dangling like little snowdrops are the blooms of the Two-winged Silverbell (Halesia diptera).  These attractive little trees are often found along streams and in moist stream bottoms.

Azaleas are a favorite of gardeners and nature lovers alike.  In East Texas the Hoary Azalea (Rhododendron canescens) reaches the southwestern extent of its range.

IMG_7914

I couldn’t resist photographing a particularly large Sabine River Wakerobin (Trillium gracile).  This lovely trillium is endemic to rich forests in the Pineywoods of East Texas and western Louisiana.

IMG_8339

Sabine River Wakerobin

Another springtime favorite of mine is the Mayapple (Podophyllum peltatum).  This characteristic spring ephemeral of eastern forests can form large colonies in East Texas, often carpeting the forest floor.  The fluffy white blooms hang below the large umbrella like leaves.  Occasionally, as pictured below, the flowers may have a pink tinge to them.

IMG_6995

Though I photographed a few in February, I couldn’t resist stopping to photograph some roadside populations of Birdfoot Violets (Viola pedata) in early March.

IMG_1495

Also common along roadways and dry, open woods is the Plains Wild Indigo (Baptisia bracteata).

IMG_7416

I photographed this Yellow Star-Grass (Hypoxis hirsuta) with fresh morning dew still clinging to the bloom.

IMG_7450

Yellow Star-Grass

Another characteristically eastern forb that reaches its southwestern extent in East Texas is the Lousewort (Pedicularis canadensis).  Most of the flowers in Texas are yellow, however I have occasionally observed them with hints of maroon.  Lousewort is reported to provide a plethora of medical uses.  It’s roots have long been used to brew a tea that helps treat digestive and stomach problems and ulcers.  Its leaves can also reportedly be ground into a poultice that helps alleviate swelling, muscle pain, and several skin conditions.  Drinking its leaves in a tea is said to sooth sore throats, coughs, and headaches.  It is also said to act as a powerful aphrodisiac.

The beautiful Big Thicket Phlox (Phlox pulcherrima) is endemic to the forests of East Texas.  Like so many other species in this area of significant habitat modification by man, it is now most common along roadsides.

IMG_7679

Big Thicket Phlox

The Nodding Penstemon (Penstemon laxiflorus) is also common along roadsides.  It is so common that I never gave it much thought as a photographic subject, however this native has truly unique, beautiful flowers when viewed up close.

IMG_1479

Nodding Penstemon

During March I also made a few visits to the Big Thicket to check on a species that I checked off my list in February: The Federally Endangered Texas Trailing Phlox (Phlox nivalis ssp. texensis).  The plants were looking healthy and were still blooming mid-March.

IMG_8446

Growing near the phlox I saw several Dollarleafs (Rhynchosia reniformis), a species of the coastal plain of the southeastern United States.

IMG_1610

I’ll close out this March recap with a beautiful scene from a longleaf pine savannah near one of the few known locations of Texas Trailing Phlox.  Here Rose Mock Vervain (Glandularia canadensis) thrives following a fire.  These showy blooms are a testament to fire’s ability to maintain and vitalize certain vegetative communities.

IMG_8489

With March of 2017 behind us, it’s time to move into April, where I hope to really start get going on my 2017 list of biodiversity goals.
