162 BOTANY OF THE VOYAGE OF THE SULPHUR. 
This plant differs from Kunth’s description, in that it is certainly mone- 
cious, not dicecious, as observed by Klotzsch (Lond. Journ. Bot. 2, p. 42), but 
the involucra are generally aggregate as described by Kunth, not solitary as 
stated by Klotzsch, and in these specimens they are smaller, with very much 
smaller coloured lobes than in Schomburgk’s specimens. The species, though 
variable, and very common from the Southern United States and Mexico to 
Brazil, appears to be constantly distinct from all the European and Asiatic 
species allied to E. chamesyce, but is probably the same as FE. depressa, Torrey, 
and if so, the latter name might be substituted for the erroneous one of dioica.
