It is nearest related to H. Utuhensis, but differs by the decumbent stems and broader 
and shorter bractlets and is apparently a very rare plant. It was included by Dr. Wat- 
son in H. pygmaca, from which it differs in the inflorescence, the absence of bristle- 
points to the leaflets and the broader petals.
