This widely scattered southeastern species is most common in roadsides and other mowed areas on fertile soils, including old urban lawns (locally abundant under sugar maple); it may have spread greatly after settlement. Some colls. from Ky. are immature and not easily distinguished from typical retroflexa. C. texensis differs in its perigynia averaging 1-1.3 mm wide (versus 1.4-1.8 mm), with l/w usually 2.3-3.1 (versus 1.5-2.3), and the basal spongy portion < 1.1 mm long (versus 1.1 mm or more), usually less distinctly nerved, and more rounded in cross-section. Its widest leaves are narrower on average (ca. 1-2.5 mm versus 1.4-3.4 mm), and lower bracts tend to be shorter (up to 3 cm versus 6 cm), but these are not reliable characters; see Downer & Hyatt (2003) and FNA 23.
