Target Species: Soapwort Gentian (Gentiana saponaria)

One of our country’s more enigmatic plant genera is Gentiana.  Spring may be more often associated with wildflower blooming, but many of the brightly colored species of this genus bloom in the fall, and in the case of Gentiana saponaria in Texas, into the winter.  The genus is also unusual in that many of its flowers do not open, remaining forever in a bud-like state, despite having fully developed sexual organs hidden within the closed petals.

Gentiana saponaria is one of a suite of species that reach the southwestern extent of their range in extreme Eastern Texas.  In Texas it is very rare, probably occurring in five or less populations.  While elsewhere within its range it might occur in prairie remnants and moist woodlands, in East Texas they seem to be confined to a few mature forested seeps nestled within longleaf pine savannahs.  Associated species include Pinus palustrisMagnolia virginianaNyssa bifloraAcer rubrumPlatanthera ciliarisVeratrum virginicumEutrichium fistulosumOsmundastrum cinnamomeum, and more.

County-level distribution of Gentiana saponaria.  Yellow counties indicate that the species is present and rare.

Soapwort Gentian has been on my radar for several years now.  Very few pictures from Texas exist, and I suspect that reflects that very few people have seen this plant in Texas.  Being at the periphery of its range, suitable habitat in East Texas is likely at a premium.  Despite their preferred habitat appearing to be relatively common in Deep East Texas, this plant persists at only a handful of sites.  It is likely that there are other factors influencing its distribution that we don’t fully understand.

The perpetually closed nature of this gentian’s blooms has always intrigued me.  It is likely pollinated primarily by bumble bees and large beetles, which are strong enough to push their way through the closed petal lobes.  It may also, however, be pollinated by tiny beetles that are small enough to work their way between the tiny gaps at the tip of the blooms.  Throughout its range the flowers of Gentiana saponaria vary from white to electric blue to purple.  In Texas, the buds are lime green as the develop, and as the flower matures it turns sky blue.  Then, as it fades, it gradually turns to deep purple and ultimately tan before it withers.  My friend and author of Wild Orchids of Texas, Joe Liggio likened the blooms to a cluster of Christmas lights, a fitting description if you ask me.

The genus Gentiana has long history of utilization for its medicinal properties.  The root has a multitude of purported uses including as an remedy for snakebite, digestive issues, and a variety of other ailments.  Compounds from the roots have proven to be anti-inflammatory, antiseptic, and beneficial for the treatment of liver disease.

To see this plant, I communicated with some contacts with the National Forests and Grasslands of Texas.  They pointed us in the right direction, and the first weekend of November Carolina, our friend Scott and I set out to look for them.  We found dozens of plants scattered along the upper reaches of a baygall within a fairly extensive rolling longleaf pine savannah.  The baygall is partially fed by a small springfed stream.  The plants were growing along the banks of the stream and in the drier portions of the baygall.

After spending some time at this site, we explored some other baygalls in the area.  After striking in several areas, we found a handful of plants at what we suspect is a new location for this species in Texas.  I sent the information to the Forest Service, and they confirmed that it had not been previously documented in that area.

An added bonus of searching for wildflowers in autumn is the fall foliage, set ablaze by the annual process where leaves break down chlorophyll to reveal their other brightly colored pigments.  Though it was still early in the season, that day we admired the changing colors of elms, maples and hickories.  Perhaps most striking were the fronds of Cinnamon Fern within the baygalls, that looked more like flickering flames than once lush Pteridophytes.  Though there are a few more species that may bloom into December, photographing Gentiana saponaria essentially brings a close to the East Texas wildflower season, and I can definitively say that I went out on a high note.

June Recap

Eastern Featherbells (Stenanthium gramineum) bloom in a mature pine-hardwood forest.

June got off to a slow start, but I finished strong, checking four more species off my list:

Saltmarsh False Foxglove (Agalinis maritima)

Velvetleaf Milkweed (Asclepias tomentosa)

Correll’s False Dragonhead (Physostegia correllii)

Starry Campion (Silene stellata)

In early June I photographed this pair of ox beetles (Strategus antaeus) with my good friend James Childress.  We have two species of ox beetles in East Texas.  Strategus antaeus is smaller, with proportionately longer, pointed horns.  Strategus antaeus is much larger, with blunt tipped horns.  S. antaeus is primarily a species of the coastal plain, with East Texas marking the southwestern limit of its range.  It occurs in open, sandy woodlands, savannahs, and prairie openings.  The large horns of the male are used in combat to with other males to win the favor of a female.

In mid June I visited one of my favorite vegetative communities: the herbaceous hillside seep.  This particular site is on private land that is managed by a combination of fire and mechanical clearing.  Historically these communities would have been kept free from woody vegetation through a combination of frequent lightning-ignited fires and poor, saturated soils.  These communities are home to a variety of rare and interesting species including carnivorous plants and a variety of orchids.  Pictured below are Pale Pitcher Plants (Sarracenia alata) and blooming Pinewoods Rose Gentians (Sabatia gentianoides).  I hope to highlight this community more in a future blog entry.

Herbaceous Hillside Seep

One of the herbaceous seep’s most striking summer displays comes from the Bog Coneflower (Rudbeckia scabrifolia).  This rare plant is confined to extreme eastern Texas and western Louisiana.  Here it’s habitat has all but disappeared over the past century and a half.

Similar to the herbaceous hillside seep, but occurring in areas where fire historically did not penetrate is the forested seep.  These areas are locally known as “baygalls” in reference to two typically dominant species: Sweetbay Magnolia (Magnolia virginiana) and Tall Gallberry Holly (Ilex coriaceae).  Like the herbaceous seep, baygalls are home to many rare species.  Pictured here are the blooms of the toxic Virginia Bunchflower (Veratrum virginicum).  These handsome plants may reach a height of 7 feet.

Another impressive summer bloomer is Physostegia digitalis, one of the false dragonheads.  They can reach heights of six feet or more and bear dozens of pale pink flowers.  Like the Bog Coneflowers, they are a species endemic to the West Gulf Coastal Plain, and are limited to East Texas, western Louisiana, and extreme southwestern Arkansas.  They are quite common in East Texas, existing in open sandy woodlands and highway right-of-ways.

Ongoing survey efforts for the extremely rare Louisiana Pine Snake (Pituophis ruthveni) on private land produced this Northern Scarlet Snake (Cemorphora coccinea copei).  Though they may be locally common in appropriate habitat, their preferred habitat, which includes sandy longleaf pine savannahs, xeric sandhills, and similar habitats has all but disappeared.  Scarlet snakes are specially adapted for burrowing, and they spend most of their time below ground. In East Texas their greatest periods of surface activity seem to coincide with the peak season for reptile nesting. During this time they seek out their favorite prey: reptile eggs.

I photographed this jewel beetle (Acmaeodera sp.) as it went about unwittingly pollinating Woodland Poppymallow (Callirhoe papaver).

This has been a good year for Eastern Featherbells (Stenanthium gramineum).  I prefer landscape shots that showcase their whispy blooms over detailed shots of individual flowers.  Eastern Featherbells is one of a suite of species typical of the eastern United States that reaches it southwestern limit in the Pineywoods of East Texas.  It seems to be uncommon to rare throughout most of its range.

A number of milkweed species bloom in the height of summer.  One of the more easily overlooked species is the Whorled Milkweed (Asclepias verticillata), whose tiny flower clusters hardly look like blooms from a distance.

The Federally Threatened Neches River Rosemallow (Hibiscus dasycalyx) occurs in just a few East Texas Counties.  It can be differentiated from the similar Halberd-leaved Hibiscus (Hibiscus laevis) by the dense hairs on its calyces.

As the Texas summer wears on, spending time outside becomes more and more unpleasant, however some of our most interesting species are most active and easiest to see in these sweltering months.  I look forward to seeing what July has in store.
