Discussion

Of conservation concern.

Jepsonia heterandra is relatively uncommon and is apparently restricted to crevices and alluvium of very specific rock types. It has been suggested (R. Ornduff 1969b) that both the mineral content and texture of the substrate influence the distribution of this species. Heterostyly in the genus was first recognized by Eastwood in her description of this species.
