foliis vaginisque villosis.—Sierra Leone, Don; South Africa 
and East India. 
This is the same variety as the one gathered by Krauss, at 
Port Natal, under the n. 147. Kunth excludes from the 
species the forms with pubescent leaves, which Willdenow, 
Trinius and others admit. The species differs little from 
P. scrobiculatum, except in the shorter spikes with a broader 
rhachis. 
The P. barbatum, Schum. et Thonn., from Guinea, is said to 
be likewise very near P. serobiculatum.

This is probably a mere pubescent variety of O. latifolia, to 
which ought to be referred several of the Brazilian supposed 
species. 
l. Leptaspis sp.—Fernando Po, Vogel. 
This is a single imperfect specimen, insufficient to charac- 
terize the species, if it be distinct from L. urceolata, Br. It 
agrees precisely, as far as it goes, with a Ceylon specimen, 
received from Dr. Gardner under the n. 1045 ; and both appear 
more slender, with fewer and smaller flowers, than the specimens 
from Penang, (Wall. Catal. n. 8901), from Malacea, (Griffith), 
and from the Philippine Islands, (Cuming, n. 1739), all of 
which agree with Bennett’s description and figure of L. ur- 
ceolata.

of the Niger on Stirling Hill, Ansell.
