Only an estimated 20 population centers survive, and since most popluations are clonal, these may represent very few genetically different individual plants. The species' geographic range is limited to coastal south Texas and northeastern Mexico. Much of its original habitat has been converted to agricultural fields and pastures. The remnant, fragmented native prairies and savannahs are threatened by continued habitat distruction, agricultural chemicals, and by invasive, non-native grasses, which are commonly planted in the area.
