Fl. 23: 267. 1930. The type locality for this plant is given as "near Sanderson, Texas." It resembles C. Lindheimermna Scheele very closely, but is separated from that species primarily by its fruit characters. C. Orcuttii has a nearly glabrous legume 6-10 cm. long, whereas C. Llndheimeriana has a pubescent one 3-6 cm. long. Recent collections of C. Orcuttii have been made only in the Del Norte Mts., Brewster Co.--B. L.
