Description:Distribution and Ecology - VENEZUELA: Bolivar: Auyan-tepui, alt. 2200 m, G. H. H. Tate 1362 (type collection, NY); same locality, Car dona 2663 (NY, US).Apparently endemic to Auyan-tepui, Venezuela.
The pubescence of this species is dendroid-stellate with the branches more
or less evenly distributed along the main axis of the hair. In respect to pubescence
at least, R. peduncularis is the closest relative; in that species the central
axis, of the hairs is not developed and a stalked, many-armed, star-shaped form
results. The form of the inflorescence and flower parts, as well as vegetative
differences, separates the two species.
