Notes

Much habitat already lost to development; also threatened by non-native grasses. Closely related to and difficult to distinguish from C. staticoides. See Annals of the Missouri Botanical Garden 21:61 (1934) for original description, and Phytologia 66(2):159-160 (1989) for taxonomic treatment.
