remarkably constant in its characters.

Varronia dasycephala, Hook. f. (4), 261, not Desv.— Cartes Ist.: 
Edmonston (hb. Gr.). Certainly different from any other species on 
the Islands, and clearly distinguished from C. dasycephala by the simple 
widely spreading tawny setae which cover the stem. Unfortunately the 
material is too poor for description. Endemic.
