This small creeping species is clearly related to L. 
Deistel Schltr. which also occurs in Kast Africa. It may 
be distinguished by the lip being suddenly broadened in 
the front part with the outer margins very coarsely 
toothed. The basal callus is more clearly transverse, with 
two lateral rounded knob-like teeth.
