1. R. africana, Benth. ex Hook. f. in Hook. Ic. t. 1430. Rootstock 
as thick as a man’s finger, fleshy, wide-creeping, sending out cylindrical 
fibres. Leafy stem 4-5 ft. long. Leaves oblanceolate-oblong, 1 ft. or 
more long, 2—4 in. broad, acute, narrowed gradually to the base, mode- 
rately firm, glabrous on both sides; petiole 1-2 in. long. Flowering 
stems many from the rootstocks, distinct from the leafy stem ; panicle 
lax, thyrsoid, slightly compound, 3—4 in. long ; peduncle 4-6 in. long, 
with many scariose sheaths; bracts oblong, obtuse, pale red, 4-Z in. 
long; lower flowers about 3 toa branch, on short erecto-patent pedicels. 
Calyx funnel-shaped, 4—4 in. long, finally bright orange-yellow, shortly 
toothed at the apex. Corolla-tube not exserted from the calyx; lobes 
oblong, } in. long, the upper spoon-shaped. Lip ovate-cuneate, flat, 
¢ in. long, under 4 in. broad, with a narrow claw as long as the blade, 
with a tooth on each side representing a lateral staminode; fertile
