Jake and I were looking for Casey but couldn't find him.
Leaves less than 3 times as long as wide; inner phyllaries glandular to the tip.

Unique rosinweed existing as a scour species on gravel breaks
This might be a disjunct population of Silphium albiflorum x laciniatum, near the AR/OK state line. There were about 100 plants at the roughly 2-acre site. They were growing in a sunny shale glade and were growing with Grindelia lanceolata, Ambrosia bidentata, Eupatorium serotinum, Schizachyrium scoparium, Ruellia humilis, Crocanthemum rosmarinifolium, Tridens strictus, Asclepias hirtella, Boltonia diffusa, and Oenothera filiformis.
Flowering specimens averaged 60 cm tall, with the smallest one 30 cm tall and the largest one 85 cm tall. Leaf tips were acuminate to apiculate. Calyx lobes were stipitate-glandular. All of the flowers had very pale yellowish-green ligules (9-19 per head) that were mostly less than 2.5 cm long. Disc florets were lemon-yellow as shown.
We were later told that the adjacent McCurtain County, OK has a couple of similar populations on prairie glades.
Potentially undescribed rosinweed inhabiting moist, rocky habitats.
American featherfoil (Hottonia inflata) Primulaceae
I was by myself and got lost in the forest. I couldn't find the orchid but found these strange looking flowers instead.
Comparison of five species of Dichanthelium, from left to right: D. sphaerocarpon, D. boscii, D. commutatum var. commutatum, D. commutatum var. ashei, D. dichotomum var. dichotomum.
Images compare the spikelets, lowest node, widest leaf, and overall habit.
Open depression pond. Plants 3 ft tall.
Growing on/in paper wasp. Found on young longleaf pine. This pine needle was sticking out the side of the trunk. The wasp's body was up against the trunk as shown in the photos with a brown paper bag. I didn't take a photo in situ because I didn't have a camera with me.
Specimen given to David P. Lewis.
The last two pictures are UV flora, aka Bee Vision
Shot by a full spectrum camera with UV pass/IR suppressed filters.
From the UV pictures, I don't think these flowers are pollinated by bees.
I was told these flowers are pollinated by butterflies. Regardless, butterflies could see UV too, so the UV filter that I use is still good enough to capture the flowers' UV nectar guide.
From the UV pictures, you could see different part of flowers have different colors...the flower in the center looks like being pollinated by butterflies already.

Site now inundated by a man-made small reservoir. This was the westernmost known site for Sarracenia alata. I don't know if anyone has checked to see if there might be remnants upstream or on the lakeshore.
Thick woody main stem with multiple branching. Plants were all short, shrubby mounds.
About a dozen Chamaecrista in very sandy soil on an oxbow of the Red River. These plants were from a single, thick stem, were widely branched and were 24-30 inches tall. They were just starting to flower. The branches were red on one side, green on the other, and the red sides were moderately covered with hairs that curled back toward the branch. My photos show the entire plant, but don't show lower stems which were thick, textured, and grayish. Photos of the lower stem can be seen here: https://www.inaturalist.org/observations/232882783.

Keith 1599, clayey pipeline ROW, unusually far north.
This suggestion was not what I expected. I expected a tree.
Blades to 7cm long, 5-6mm wide with cartilaginous margins
Some lower nodes with sparse appressed pubescence.

Crosby Arboretum - Biological Treatment pool. Small Dichanthelium. Spikelet 2.0mm, glabrous. Leaves 10+ times as long as broad. All parts glabrous. About 4-5 leaves per culm.
Former homestead now wet depression in mulched restoration area. Spikelet 2mm, leaf 12.5 cm x 8mm.
herb; last photo contrasts this with 4 other intermixed Juncus
Similar to Dichanthelium linearifolium but glabrous and often larger. A species of acidic woodlands, glades, and rock outcrops.
I key to acuminatum-group, maybe D wrightiana
Not sure. Seepage ecotone between cypress dome and flatwoods. Spikelets finely puberulent
Rooting at nodes. Voucher: https://bisque.cyverse.org/image_service/image/00-3VK22cDcaKwhNv2xHFFqd5/resize:4000/format:jpeg
