FLORA OF MADAGASCAR. 299 
Mr. Baron on the mountains of the province of Imerina. The 
former is his 2028 and 2156, and the latter his 2041. [Vide op. 
cit. (1883), pp. 129,8130, t. 238.] 
STENOTAPHRUM OOSTACHYUM, n. sp. 
Perenne, glabrum, dense exspitosum, vaginis laxis complanatis, folio 
parvo lanceolato, spicis parvis oblongis, rhachi utrinque late applanata, 
spiculis 2-3-jugis, gluma exteriore minuta sterili, interiore oblonga acuta 
flori zequilonga. 
Stems densely intermatted, decumbent and rooting from the 
nodes of the lower part, the ascending flowering branches not more 
than 2-3 in. long. Sheaths of the stems i-i in. long, loose, 
broad, flattened, ciliated at the margin; lanceolate free blade 
3-1 in. long, i-i in. broad. Peduncle thickened below the soli- 
tary oblong spike, which is not more than i-j in. long, with a 
rhachis flattened on both sides to a diameter of 3 inch, with 2-3 
spikelets on each side inserted in a deep groove. Spikelets erecto- 
patent, 4.5 in. long; the outer, sterile glume very minute; the inner 
as long as the flowering glume, which is oblong, subacute, acutely 
keeled, without any other ribs.—Central Madagascar, Baron 655! 
A curious little plant, nearly allied to the common cosmopolitan 
S. complanatum, Schrank. 
STENOTAPHRUM UNILATERALE, n. sp. 
Perenne, glabrum, dense czspitosum, caule florifero elongato, vaginis 
laxis complanatis ciliatis, folio lineari, spica elongata cylindrica rhachi uni- 
laterali applanata, spiculis geminis una sessili, altera pedicellata, glumis 
exteriore minuta emarginata sterili, interiore oblonga acuta flori zqui- 
longa. 
Stems densely intermatted, trailing at the base and rooting 
from several nodes, the ascending flowering branches a foot long. 
Sheaths of the stem 11-2 in. long, loose, flattened, densely ciliated 
on the edge; blade linear, 2-3 in. long. Stems ending in a 
single compound spike about 3 in. long, with a rhachis flattened 
on one side of the flowers only to a breadth of a line, the spikelets 
inlaxly disposed pairs along a slender flexuose axis, the inner 
spikelet of each pair sessile, the outer with a short pedicel, which, 
however, is adnate to the flattened 1-sided rhachis. Spikelets 
oblong, acute, 2-flowered, 1 in. long; the outer, sterile glume very 
short, distinctly emarginate ; the inner similar in shape, size, and 
texture to the flowering glume.—Central Madagascar, Baron 
1069! A very curious and anomalous species.
