Type: Linden 5 57, Tabasco. 
This species is characterized by its leaves, very tomentose 
below and almost glabrous above. However, there is consider- 
able variability in the indument of the leaves, particularly with 
regard to the long appressed hairs on the upper surface. ese 
are sometimes entirely wanting, and yet often very abundant.
