A well-distinguished species, the most southerly of the 
Heliolepis series, findin rhaps its nearest relation within 
the series in Rh. heliolepis itself. Like that plant it has broad 
leaves, but the surface scales are much more numerous and much 
closer set and give a diagnostic mark at sight. Another easily 
seen differential character is the tubular-campanulate corolla 
and the shorter ovary. Altogether Rh. plebetum is a more 
lepidote plant than Rh. heliolepis. a 
The Lae is in cultivation, raised by Mr. J. C. Williams of 
Caerhays Castle from seed collected by Forrest.
