LEMPHOLEMMA Körb.
The genus is seldom collected and several collections
still await identification. Further species are expected
to occur in the study area.

The genus is poorly known and requires meticulous
collections and systematic TLC analysis. The
treatment presented here is therefore provisional.

crassissima (Hue) Lettau
