This is a rare and very distinct species perhaps most closely related to R. strigil- 
losum Franchet, which has strigose hairs covering the branches, petioles and fruit, 
very different tomentum, mainly confined to the center of the lower surface of the 
leaves, larger flowers and very differently shaped fruit. Our plant may also be 
compared with R. pachytrichum Franchet which is easily distinguished by the 
leaves being glabrous on the under surface, with the exception of the midrib, by 
larger flowers, villose stamens and by the larger, stouter and glabrescent fruit.
