Also in Madagascar and South Africa. 
The type of this species has the compressed tight-packed spikelets of the 
C. exaltatus group, but the yellow deciduous rhachilla-wings of the C. digitatus 
group (these wings running up the margins of the glumes). Apart from the style 
being 3-fid, the structure appears to me remote from that of C. alopecuroides. The 
African examples agree well with the Madagascar, but have shorter spikelets.

Primary rays of umbel 12 in. long, secondary 4 in, long. Spikes 2-2} in. long; 
dense, but not rigid. Spikelets obliquely erect, 12—18-flowered ; wings of rhachilla 
very narrow. Nut 7 the length of the glume, obovoid.

This variety should perhaps rather be appended to C. exaltatus.

2-6 ft. long, at the toptriquetrous, smooth. Leaves 3 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 angles. Spikelets 4—-} by z¢ i2-, 
20-flowered, not much compressed, yellowish-brown; wings of the 
rhachilla lanceolate, yellow, very caducous. Glumes ovate, scarcely 
mucronate, the back 3-5-nerved, greenish-brown, the sides yellow 
without striations. Stamens 3; anthers linear-oblong, not crested. 
Nut } the length of the glume, trigonous, oblong-ellipsoid, often some-
