Muizenberg Vley, 14th Nov. 1897. No. 3563. Male plant 
only. 
We have not had an opportunity of examining the type of 
this species, but the present plant agrees exactly with Braun's 
description of it. It is, however, important to note that the 
cells at the base of the branchlets, representing undeveloped 
stipulodes, are in a single series only, which would appear to 
place the species in the group Haplostephane.
