A very lovely little plant, if minutely examined as the struc- 
ture of the flowers entitles it to be. It was found growing on 
Mangroves in the Nun River, by Mr. Barter, late Botanist to the 
Niger Expedition under Commander Baikie, when living plants 
were sent to Kew, and again by Mr. Gustav Mann, in 1860, 
from the same river. ‘These plants have flowered with us both 
in April and in October of 1861. 
Descr. Plant small. Pseudobulbs scarcely an inch long, — 
ovate, thickly clustered, each bearing two oblong-lanceolate ob- 
tuse or retuse eaves, tapering at the base, scarcely conduplicate, 
except in the dried state. Scape or peduncle from the base of 
the pseudobulbs, short, terminated by a slender, flexuose, droop- 
ing pikes of many small subsecund flowers. Rachis granulated 
with small tubercles. Bracts broadly ovate, at the base of the 
sessile ovary, reflexed. Perianth externally muricated, as well as 
the ovary, superior or dorsal sepad erect, purplish-brown, yellow-
