3. R. platyanthera, Reichb. f. Otia Bot. Hamb. ii. 104. Plant 
slender, 16 in. high. Tuber globose, 5 lin. long. Leaves squamiform 
at the base, black-spotted or wholly black towards the apex, upper ones 
linear-lanceolate, acuminate, appressed to the stem, 43 in. long, 5-7 lin. 
broad, decreasing upwards. Spikes congested, many-flowered. Bracts 
ovate, very acuminate, the lower as long as the flowers. Dorsal 
sepal broadly ovate, subacute; lateral 21 lin. long, larger than the 
dorsal, obliquely ovate, with a contracted apex; posterior side rounded. 
Petals ovate, very obtuse, as long as but narrower than the dorsal 
sepal. Lip scarcely 3 lin. long, trilobed, with a linear base; lobes 
narrowly linear; side lobes diverging; front lobe a little curved and 
slightly bidentate ;. spur nearly twice as long as the lip, slender at the 
base, clavate and bidentate at the apex. Column large; anther chan- 
nels slightly produced, uncinate, closed at the apex. Stigmatic processes 
deflexed, ligulate, obtuse, parallel in front, a little diverging behind.

the apex; front lobe a little broader than the side lobes, narrowly 
ligulate, obtuse; spur pendulous, apex subclavate, obtuse, nearly as ` 
long as the pedicels, nearly twice as long as the lip. Stigmatic processes 
with very broad diverging arms, clavate, scarcely bipartite in front; 
posterior lobe reduced to a linear appendage ; anterior lobe elongate. 
Anther cells small, obliquely superposed to the stigmas. Rostellum

This is the first West African species ; and is said to be most allied to R. alcicornis, 
Kriinzl. I have not seen it.
