Orehids from a country where the average annual rainfall 
ranges from 1 to 4 inches, and where the landscape is frequently 
black from the remains of bushes killed by drought, are some- 
what unexpected. Neither Drége nor Zeyher, who were both in 
Namaqualand during dry periods, have recorded any. The pre- 
sent species was first sent to me in 1878 by the Rev. Mr. Morris, 
to whom lam indebted for many good plants of that curious 
region ; and I subsequently found it myself in September 1883, 
as above, in company with Pterygodium Volucris, Sw. Besides 
these, I found Satyrium pustulatum, Lindl.?, on Spektakel 
Mount, and a Holothriz sp. ? near Ookiep, making four Orchidese 
in all. 
In Disperis the form of the labellum is very variable, but seems 
pretty constant in the species, and therefore affords good specific 
characters, though difficult of expression in few words.
