The pilose and stipitate-lepidote branchlets and the lepidote corolla-lobes dis- 

 tinguish this new species from all other members of its group. It is, perhaps, most 

 closely related to R. polycladum Franchet; this has narrower acutish leaves, a 

 different calyx and a glabrous like the branchlets only lepidote corolla.
