Casey and I found this nice patch of Trillium flexipes in late April at Mingo NWR.
Many thanks to Stephen, Pete and Casey for introducing me to this special plant this spring. Hottonia inflata, or American featherfoil, is ranked as imperiled (S2) in the state of Missouri and is a species of conservation concern in most states within its range. The destruction of wetlands habitats in the U.S. is the cause of the scarcity of this winter annual member of the primrose family (Primulaceae). The stems of this plant are spongy organs filled with air pockets and are the characteristic described in the specific name – inflata.
Photographed at Shaw Nature Reserve in August of 2020, this is the white form of Cirsium discolor, the pasture thistle.
Here is a genus that I find interesting. The Penstemon is made up of approximately 270 species and is the largest genus of flowering plants that are endemic to North America. Now classified in the plantain family (Plantaginaceae), this is a very diverse genus found across a variety of habitats and altitudes. Most species should be readily identified as a Penstemon due to their unique flower morphology. The corolla is a fused tube, comprised of five petals that can be identified as lobes in a two on top, three on the bottom configuration. Inside the corolla you will find two pairs of stamens with anthers pushed towards the top of the open mouth. In between the fertile stamens is a staminode that lies towards the bottom of the tube. This sterile modified stamen usually ends in a brush-like structure. This is the eponymous “beardtongue”. The generic name, Penstemon, meaning “stamen-like”, also refers to this staminode.
I got to meet four species of Penstemon in bloom this year – two of which I planted in the garden. I was happy to see them bloom in their first season.
Casey and I ran into a number of spiderworts in forests, glades and prairies across Arkansas and southern Missouri during our trip in May. Although Casey did his best in identifying the plants as we came across them, my field note taking can often leave a lot to be desired and I didn’t record which photo was which plant. With approximately ten species of Tradescantia in this geography plus a few known hybrid situations as well as multiple flower colors possible in some species, identifying these just by closeup photos of the flowers would be challenging even for the experienced botanist. So, I am satisfied just to focus on the forms, colors and insect interactions of these flowers as seen in these photos.
This has me thinking about the possibility of sending in my 5D mk iv into Canon to have the conversion that enables voice notes recording. I used this a couple times when I had the 1D mk iv and think it would be useful during these trips where we are hurrying from plant to plant and location to location and I realize I left my pen and notebook in the car or at home, or am simply to lazy too use them.
Another striking member of the Melanthiaceae family is Amianthium muscitoxicum, commonly known as fly poison. This name comes from the practice of early Americans who would crush the plant’s bulbs with sugar in order to, well, kill flies. Like many plants in this family, A. muscitoxicum contains a variety of toxic alkaloid compounds that provide it protection from a variety of herbivores. I think this might be a good candidate for horticulture in high deer pressure areas, but be sure no parts of the plant can be ingested by people or domestic animals. These plants were found in Mark Twain National Forest in Carter County on May 22, 2021.
The Virginia Sneezeweed is a Missouri state endangered and federally threatened species of Helenium, first discovered outside of Virginia, by our own Julian Steyermark. I photographed these in August, 2020 at Tingler Prairie N.A. I encourage you to read this great article by Bridget Macdonald to read more of the story of this plant.
This fantastic little one is the western daisy (Astranthium ciliatum) that we found at Middle Fork Barrens Natural Area. In the xeric, shallow soils of the barrens this daisy was single-stemmed and and no more than 6″ off the ground. If only they would behave like this in the home garden! Their range is centered in Oklahoma and Arkansas although they can be found in southwestern Missouri. These were beautiful little plants and rank up with my favorites in the family.
