Looked all over with @bayoushari to find something other than T. biflora, but no luck! Confirmed ID by seeds.

I had to key this one out. The really wide pores made me think it might be T. lamprosperma, but the bracts are longer than wide and the leaves are broadly acute to obtuse, which are both key characters of T. perfoliata.

The seeds of Triodanis texana are morphologically distinct from other Triodanis spp as they have a rough "netted" texture instead of the shiny "looking glass" surface, and quadrangular in cross section, which can be seen on the ends of several in the first photograph. Another observation of note is that this plant did not have the expected obvious pubescence on the underside of the leaves.
Specimen collected by @kathymcaleese at my request. Location and time reflect approximate observation in the field.

On the bank of a runoff creek. Lower bracts were small, upper bracts very long. Pores large.

So exited to finally see this species in person, thanks to @baxter-slye. Specimens collected for Trio project and BRIT.
There are a lot of pics, and some just cropped closer, but I will use them later in a journal post so I wanted to keep them all together.
Note that the lower stem is hairy but the upper stem is not. No hairs on the back of the leaves. Pore is very small compared to all the other Triodanis spp. Bracts are all similar to each other in shape and size.

This seems to fit...Growing near the river bank in sandy soil, full sun.
Key breaks (FNCT):
Leaves glabrous on upper surface (photo 9)
Bracts broad, not linear (photo 9)
Pores near the middle (photo 5 and 6)
Pore narrowly oblong, <0.5mm wide and cartilage with narrow scarious margins (photo 6) = T. holzingeri
From description (Vascular Plants of Texas):
Lower stem hairy (photo 11), upper stem scabrous (photo 10). Capsule pores sunken, narrow, in the middle of the capsule. "Seeds lustrous, lenticular, 0.4-0.7mm long, minutely low-tuberculate in longitudinal lines" (photos 7 and 8)

After seeing @alan_rockefeller's observation HERE I had to go take a look!
Photos:
1&2 - Upright, multiflowered, calyx lobes 5
3 - Basal leaf narrow (oblong-lanceolate?) not clasping
4 - Middle part of stem shows calyx lobes 3, leaves smaller
5 - branching
6 - top of leaf glabrous
7 - bottom of leaf glabrous
8 - fruiting capsule long and narrow, fracturing near apex
9 - roots (not diagnostic)
10 - Measurement of inflorescence
11 - Seeds
12 - Seeds
I agree with @sambiology on his observation HERE that this keys out as T. leptocarpa using FNCT.
Exciting find Alan!!

Found in a roadside ditch in a parking area leading to a large creek. Leaves looked very rounded. Many in bloom, so collected, but others look less rounded.
