1. S. corrugata, LindL in Mitch, Three Exped. ii. 13. Rootstock and 

 often the base of the stem woody, the branches usuallj' difl'use or procumbent

This plant assnmes forms ai)paiently so distinct that it Is difFicult to helleve that some of 

 thrm ought not to be considered as species. In atteniptiii-r, however, to fix tlicir limits» 

 so many intermediate specimens have presented themselves, that I feel compelled to 

 follow F. Mnelltr in uniting them under one name. The fulluwin'r appear to be the most 

 marked:— "^ ^^ 



a, orbicularis. Stems short, diffuse, and tomentose. Leaves orbicular or broadly ovate, 

 deeply and coarsely crenate, cordate at the base. Flowers and fruits rather large. ' S. cor-
