Taxonomie : D'après Robertson (2004,
in Flora of North America): "
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."
