It is on the authority of ANDERSSON that I refer these specimens to var. 
pallida. Without having seen a type specimen I cannot decide whether 
Kuntn’s species really represents a variety of S. Bonplandiana. The specimens 
before me are in my opinion nothing but a more or less pubescent form and 
hardly deserve the rank of a variety. The geographical distribution is prob- 
ably the same as that of the species. Almost every species of the American 
PLEIANDRAE breaks up in a hairy and a glabrous variety which sometimes look 
very different, but mostly seem to be connected by every grade of intermediate 
forms.
