In this treatment, Celosia cristata, the cultivated cockscomb, is considered a species separate from C. argentea, its likely wild progenitor; however, it is often treated as an infraspecific entity (variety or form) of the latter. The former is a tetraploid; the latter, an octoploid, although a tetraploid race of C. argentea is known in India (T. N. Khoshoo and M. Pal 1973). Convincing evidence has been presented for recognizing this cytologically and morphologically distinct race as a separate species (W. F. Grant 1961, 1962). Celosia cristata is known only in cultivation or as an escape from cultivation.
