These observations are from a remnant prairie tract that was termed the "Walling prairie". Efforts were made in the mid-1980s to protect the tract but it was in the path of major development. TX Toll-130 now runs directly through the site and former ranchlands are now either subdivisions or commercial/industrial parks (see modern Google Earth image). All four major blackland prairie grasses were present at the time (little and big bluestem, indiangrass, switchgrass). Site visits were made by a preserves committee evaluating the site on several dates. The month is correct for the present observations; the exact date is estimated.
Small shrub around 3ft tall, likely cultivated.

Hymenopappus artemisiifolius
A few plants in maintained cemetery. Flowers mostly lacking the characteristic reddish tinge, but the leaves are consistent.
Note the phyllaries are fused nearly to the top and the ring of orange-ish glands near the top, which helps distinguishes this species from Thymophylla pentachaeta. Growing over fractured limestone in partial shade.
Apparently not a particularly well documented species. Also a lifer for me.

Mononeuria muscorum
Thought I had posted this long ago. Note the 3 veined sepals, indicative of M. muscorum.

Houstonia micrantha
2/19/2024
Patchy, possibly common, in maintained cemetery. Easily overlooked. I initially dismissed these as small Houstonia pusilla, until it became clear that they appeared significiantly smaller than the abundant Houstonia pusilla. I then thought they might be Houstonia parviflora which also has small white flowers and occurs in the region and I did not realize until I got home that the leaves were more consistent with H. micrantha. I only took two measurements in the field, the flower width of about 5mm and stem length of about 2.8cm. However, from the width, I could estimate that the corolla tube was probably around 2mm (from the profile photo), more consistent with H. micrantha than H. pusilla.
Williamson county
A healthy population, about 20 individuals, growing along the fence, some in private property. The land owner cleared most of Ashe juniper, and left these bushes alone.
The biggest one is starting to bloom, found two open flowers.
This ons is smaller, behind the fence, in a private property.
1 open flower.
Burnet county
Behind the fence, in a private property.
Two big patches, very healthy.
These Texas Almond are huge, taller than me. (I am 5'5")
I think I am done with Texas Almond (Prunus minutiflora) for a while.
The second last picture is UV flora, aka Bee Vision
Only two trees left.
I went to look for others, didn't find any.
Williamson County. True location obscured for safety of the population.
not 100% sure
minty smell...
Hedeoma is a very confusing Genus.
Travis County, Texas. Second cluster of plants found near the other plants (https://www.inaturalist.org/observations/194395968).
Location obscured with iNaturalist obscure feature, but true location is obscured as well.
Travis County, Texas. Appears to be an undocumented population not recorded on GBIF or SEInet.
Sprawling shrub 3-5 feet tall, dominant species under a Quercus fusiformis motte among Croton fruticulosis, Berbersis trifoliolata, Smilax bona-nox, and young Juniperus ashei. Mixed oak-juniper woodlands on gently sloping upland.
Incidental find in a rather precarious location. A second cluster of plants was found nearby (https://www.inaturalist.org/observations/194395969). Location obscured with iNaturalist obscure feature, but true location is obscured as well.
Heteranthera
Temporary Pool at Riparian zone
A guess bc this does not look like D. compacta

Oenothera glaucifolia
Rare. First time I have seen this species.
During Chuck Sexton's guided tour around Balcones Canyonlands NWR—couldn't have asked for a better guide!
In right of way on CR2338/Williams Drive just north of Wesley Chapel Cemetery. So far I have only seen these in the northwest part of the county.
This small plant has mint-scented foliage. It's growing in shallow water in potholes and small channels of the flat rock of a stream bed. Very pale blue.
Aristolochia erecta?
Growing on silty, clay soil. Will monitor for flowers if confirmed. Would be a rather interesting location for this species, on UT Austin campus.
A few old growth individuals on east/southeast facing slope of unplowed Blackland (Eagle Ford) Prairie remnant.
ID please thank you very much.
Sorry for the blurry picture, photobombed by my dog
This is the same seedpod around a month earlier https://www.inaturalist.org/observations/179512797
I had been watching this population for a while. It had rained the night before, and I decided to check if the seeds had ripened yet. They had. It appears that the damage on one side of the capsule had not prevented the other seeds from maturing.
Nice to see this uncommon plant still blooming in these drought conditions. These particular plants had been submerged earlier in the year but were now exposed and blooming. Note the different leaf types on the same plant: The broad rounded leaves grew when the plant was submerged; the narrowly ovate leaves are the aerial growth form.
