Var. parva, C. B. Clarke. Plants small, slender, with very narrow leaves, much

In Hens, 159, 17 8, the stems are sometimes reduced to 4 in. long, and the umbel to 
a single head of 3-5 spikelets. In the variety robusta, K. Schum. in Engl. Pfl. 
Ost- Afr. C. 120 (i.e. Holst, 2026), the umbel is more than 2 ft.in diam. The species 
varies greatly in development in India; it can generally be recognised by the 
distant glumes and subquadrangular spikelets. 
92. C. schweinfurthianus, Boeck. in Flora, 1879, 553. Stem

: Var. ? levicaulis, C. B. Clarke. Stem quite smooth at the top, 2 ft. long. 
Umbel compound ; primary rays 3-4 in. long. Spikelets (young) 2 by nearly 3 in., 
Somewhat lanceolate (i.e. narrowed at both ends), very flat, yellow. 
Mozamb. Dist. British Central Africa: Urungu; Fwambo, Carson, 19! 
I doubt this being any variety of C. schweinfurthianus. The inflorescence and 
t lanceolate spikelets are more like those of C. fenzelianus ; but the spikelets are 
broad for that species or C. rotundus or any of its neighbours.

Yays up to 10 in. long. Spikelets 1 by } in., 20-30-flowered, suberect ;
