Lindl., and B. pubescens, Harv.; and, from description, must be 
more nearly allied to B. tenuior, Reichb. f.

I deseribe from two plants in the Cape Government Herbarium 
from the above colleetors, as these are all I have ever seen. The 
tickets describe the colour of the flowers as brownish red, which 
they partially retain. The species has the habit of P. venosum, 
Lindl., but is slenderer, smaller, and quite distinct from that or 
any other species with which I am acquainted. I have not seen 
P. magnum, Reichb. f. ; but, from the description, it must be very 
different. 
[N.B. P. rubiginosum, in the dried state, resembles lax-flowering 
specimens of P. carnosum, Lindl., but is readily distinguished 
from that species by its triangular acute lip, which in P. carno- 
sum is transversely oblong and emarginate.—N. E. Bnows.]
