priority over Amaranthus gangeticus L. and A. melancholicus L., to both 
of which it has been reduced by various authors. Probably in cultivation 
or naturalized in most tropical countries.

G. E. S. 287, local name caletes apaca. 
All tropical countries, where native uncertain. 
In addition to the above species Safford reports also Amaranthus oleraceus 
Linn., apparently collected in Guam only by Gaudichaud. It may be the 
form commonly cultivated by Chinese gardeners in various parts of the 
orient as a pot herb.

cultivated and where it is known by the same Spanish name. Apparently 
a native of tropical America.

CELOSIA CRISTATA Linn. Sp. Pl. (1753) 205. 
G. E. S. 853, native name christangayo. 
A form so suspiciously like Celosia argentea Linn., that I am impressed 
with the idea that Celosia cristata Linn. is only a derived form of C. 
argentea, modified by cultivation. Cultivated in all tropical countries, un- 
doubtedly originating in tropical America.

warm countries.
