I documented a few lawn weeds in the manicured islands in a large shopping center while waiting for a phone upgrade.
This is another forb that would probably have grown much taller had it not been mown frequently. The narrow floral bracts and the capsules with pores near the apex seem to point to T. biflora.
@kimberlietx How'd I do?
Is this T. texana?
I think the way the cartilage rolls up like a window shade to reveal the pore is an awesome innovation in seed dispersal technology. Way to go Triodanis.
