Mississippi Kites in the Arkansas

Nesting Birds of Missouri, wildlife, wildlife photography

It is always nice finding your targets on a big photography trip but the icing on the cake is finding the unexpected. That is what happened here when Casey and spent some time at Moro Bay State Park in southern Arkansas. When speaking to a very friendly park ranger, he let us on to where a pair of these birds setup territory and were virtually oblivious to humans. These birds completely ignored us as they flew to and from their favorite perches, often flying mere feet over our heads. We watched the male handoff their insect prey a number of times and even witnessed a copulation, but those photos were ruined by branches.

Hottonia inflata (American Featherfoil)

native plants

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.

The gas-filled stems and leaves of Hottonia inflata allow this aquatic member of the primrose family to keep its flowers above the water’s surface.

The Beardtongues?

macro, native plants

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.

Penstemon pallidus (pale penstemon) from my front garden in St. Louis Co., MO.
A closeup of Penstemon pallidus flowers. Note the yellow beard (staminode) that is thought to aid in pollination by pushing hymenopteran pollinators towards the stigma and anthers located at the top of the corolla tube. Also note the dark nectar guides that point towards the back of the tube.
Penstemon digitalis (foxglove beardtongue) is the most common and least particular member of the genus in eastern Missouri. These plants were found in a field at Beckemeier Conservation Area in St. Louis County.
The flowers of Penstemon digitalis are mostly white in color and have a relatively long blooming period compared to other local members of the genus.
Penstemon tubaeflorus is a showy white penstemon that is found primarily in the southwestern quadrant in Missouri. These photos were taken at Tingler Prairie Natural Area near West Plains, MO.
Here you can see why this species gets its common name of ‘trumpet beardtongue.’
The large and showy flowers of Penstemon cobaea (prairie beardtongue). These were photographed from the author’s front garden in St. Louis Co., MO.
I used focus stacking to capture the details in the flower of this Penstemon cobaea (prairie beardtongue). Note the two pairs of stamens that wrap around the inside of the corolla and present their pollen-filled anthers at the top. The stiff brush-like beard of the staminode pushes would-be pollinators towards these reproductive organs.

Those Lovely Spiderworts

macro, native plants

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.

Missouri Orchids – Liparis loeselii – Fen Twayblade

macro, Missouri's Orchids, native plants

Liparis loeselii (fen twayblade, Loesel’s twayblade) is ranked as imperiled in the state of Missouri. We found these in a marly fen in Butler County, MO in bloom during late May, 2021. Within this fen, these orchids grow on the edges between small tussocks and the marl/muck, out of the way of larger competitive plants.

It may come as no surprise, due to the plain and diminutive flowers of Liparis loeselii, but this plant is considered autogamous (self-fertilizing).

Amianthium muscitoxicum (fly poison)

native plants

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.
