The type of this species has the compressed tight-packed spikelets of the 

 C. exaltaius group, hut the yellow deciduous rhachilla-wings of the C. digitatus 

 group (these wings ruiuiing up the mai-gins of the glumes). Apart from the style 

 being 3-fid, the structure a])pears to me i*emote from that of C. alopecuroides. The 

 African examples agree well Avith the Madagascar, but have shorter spikelets.

 Primary rays of umbel 12 in. long, secondary 4 in. long. Spikes 2-2-i in. long, 

 dense, but not rigid. Spikelets obliquely erect, 12-18-flowered ; wings of rhachilla 

 very narrow. Nut '\ the length of the glume, obovoid.

118. C. digitatus, Roxh. Hort. Bene/. 81. Glabrous. Stem 

 2-6 ft. long, at the top triquetrous, smooth. Leaves f the length of the 

 stem, ^ in. broad. Umbel 8-24 in. in diam., compound; bracts similar 

 to the leaves, lowest exceeding the umbel. Spikes 2 by 1 in., with 

 very many spikelets spreading at right angleis. Spikelets J-J by^Y in., 

 20-flowered, not much compressed, yellowish-brown ; wings of the 

 rhachilla lanceolate, yellow, very caducous. Glumes ovate, scarcely 

 mucronate, the back :)-5-nerved, greenish-brown, the sides yellow 

 without striations. Stamens 3 ; anthers linear-oblong, not crested. 

 Nut J the length of the glume, trigonous, oblong-eUipsoid, often some- 

 what curved, finally black. Style rather shorter than the nut ; branches 

 3, linear.— C. B. Clarke in Hook. f. Fl. Brit. Tnd. vi. 618, and in
