I'm identifying this primarily based on the range and the particular site characteristics, i.e., on loose Carrizo Sands.
lookin thru past observations; this species is in the area, & has shorter sepals.
I have never seen this plant in Bastrop before, first time sighting
So happy to find this
The plant on the right in the third photo showing a side-by-side comparison is Gutierrezia texana: https://www.inaturalist.org/observations/35627415
The plant on the left in the third photo showing a side-by-side comparison is Amphiachyris dracunculoides: https://www.inaturalist.org/observations/35627414
First two pics show two species for comparative purposes.
Specimen on right: Note V-shaped base of flower, less dense branching, longer/narrower petals compared to Amphiachris (left; https://www.inaturalist.org/observations/34926032).
These specimens were growing adjacent to one another in the same soil type (a silty, firm sandy loam).
Some sources call it "Littletooth sedge". The leaves look like grass to me but have tiny serrations or teeth on the edges that can be seen in the original size. Went back to get a photo including the leaves as suggested by @sambiology.

iNat guess
Growing in dry shade and pt shade
See spines at base of petioles, on abaxial side.
Pop up in seed plot area, not planted, about 6ft height
I should know this from previous help with ID but do not remember...
Galium texense???
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.

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.
