Celosia argentea
Celosia palmeri
Celosia argentea is locally escaped from cultivation, and perhaps originally native to India.

In the original description, S. Watson indicated that Celosia palmeri occurs in “western Texas and northeastern Mexico.” Celosia palmeri has been reported from Cameron County, Texas (C. F. Reed 1969b) and the trans-Pecos region of Texas (C. F. Reed 1970). We have been able to confirm its occurrence only in the south Texas plains region. Herbarium specimens of C. palmeri are typically paler green than those of C. nitida.
