3. H. lancifolium, C. B. Clarke. Nearly glabrous. Stolons 

 clothed with elliptic brown scales, hardening into rhizomes. Stem 8-5 

 ft. long, rather slender, with nodes (bearing long leaves) throughout its 

 length. Stem-leaves 10 by 1^^ in., caudate-acuminate, :3-nerved, at the 

 base as though petioled. Corymb 8 in. in diam., of 35 spikes ; lowest 

 bract 8 in. long, like the leaves. Spikes in fruit J by 4 in., ovoid-lan- 

 ceolate, brown, of 20 spikelets. Bract to spikelet yV-i in. long, hardly 

 acute. Glumes to the two lowest male flowers oblong, keeled, nearly 

 as long as the bract. Sterile flower 0. Style 2:-fid. Nut ellipsoid-lan- 

 ceolate, flattened, brown, much longer than the bract, 7-nerved in the 

 lower half, the upper half being the style -base confluent with the nut.

4. H. africanum^ Xees in Linncea, ix. 288 name only. Nearly 

 glabrous. Stolons 0.. Stem-base woody, obliquely descending, densely 

 clothed with smooth roots -^^ in. in diam., apparently standing in water. 

 Basal leaves numerous, IG-SO by h in., o-nerved. Stems (scapes) from 

 the axils of the crowded leaves, 1-2 ft. long, leafless, rarely with a node 

 (carrying a small leaf) near the top. Panicle corymbose, varying from 

 1 in. in diam. with 8 spikes to 4J in. in diam. with 80 spikes, some- 

 times proliferous ; lowest bract rarely so long as the inflorescence, 

 linear with a dilated base (not like the leaves). Spikes J in. long, in 

 flower narrow-cylindric, in fruit ellipsoid, brown. Bract to the spikelet 

 y^ in. long, elliptic, obtuse. Glumes to the two lowest male flowers hardly 

 shorter than the bract, boat-shaped, distinct. Sterile flower-glume 0. 

 Nut obovoid, flattened, longitudinally ribbed, crowned by a smooth 

 ovoid beak (style-base) shorter than the nut ; but there are many small 

 infertile nuts in which the beak is much larger than the nut (as is seen 

 in several of the Indian polygamo- dioecious species). — Steud. Syn. PI.
