Mozamb. Dist. Portuguese East Africa: Zambesi Delta; Kongone River, 
Kirk ! 
Frequent in South Africa. 
The Zambesi example is the variety longibracteata, C. B. Clarke in Durand & 
Schinz, Conspect. Fl. Afr. v. 570; but I find (in this as in many other species 
of Cyperacee) the development of the leaves and bracts so variable that not even 2 
variety can be established on such a character.

Glabrous. Stolons ;},—;4; in. in diam., long, not always present. 
Stems 12-20 in. long, at the top trigonous and smooth, at the base 
suberect and bulbous, sometimes (as in Baikie’s examples) with the 
bulb + in. in diam., solid, woody. Leaves nearly as long as the stem, 
$-} in. broad. Umbel compound, sometimes open, 4—6 in. broad, more 
often 2-4 in. broad, not rarely contracted almost in a head; bracts 3-9, 
similar to the leaves, the lowest overtopping the umbel. Spikes 
loosely spicate, of 5—11 spikelets, in flower divaricate, but in dried 
specimens usually clustered, erect. Spikelets $ by 3'5—-y'5 in., much 
compressed, exactly linear with parallel sides, 20-flowered, straw- 
coloured or frequently purple-spotted; wings of the rhachilla very 
narrow. Glumes ovate, boat-shaped, obtuse, 1-3-nerved, approxi- 
mate on the rhachilla, in dried specimens usually tightly imbricated ; 
Margins shining, scarious. Style shorter than the nut; branches 3, 
linear, exserted.—C. B. Clarke in Durand & Schinz, Conspect. FI.
