It is questionable whether this should be maintained as a species or reduced 
to a variety of A. nyctaginea; both treatments have been given it by various 
authors. The northern plant, the typical form, seems to vary from A. nycta- 
ginea principally in the shape of the leaves, certainly not a very good specific 
difference. In Texas, however, shading gradually into the northern form, there 
is a plant which is very different from A. nyctaginea, Not only are its leaves 
different in shape, but the plant is much more slender in every part, and 
there are other differences. This plant, I think, certainly deserves specific rank, 
and it is so closely related to A. floribunda that IT have thought it better to 
include it here under that name rather than give it a new name.
