Also in South Africa, where this type form is rare. 
I have described above the Upper Guinea plant, the type of Vahl, and distinct 
enough from C. compactus, Lam., by the broad flattened spikelets, few to a 
head. 
Var. pseudonivea, C. B. Clarke. Spikelets 3-13 to the head, 2 by g-+in, 
somewhat compressed, but turgid.— C. pseudoniveus, Boeck. in Verhandl. Bot, Ver.

Frequent in South Africa, 
The type of Boeckeler’s Cyp. pseudoniveus is Schinz, 376, which Buchanan, 
1424! 1425! matches. Several of the numbers cited for this variety were formerly 
referred to C. compactus, Lam., and I see no good line between this var. pseudo- 
nivea and C. compactus. 
14. C. ochrocephalus, (. B. Clarke in Durand & Schinz, 
Conspect. Fl. Afr. v. 571, not of Steud. Glabrous. Rhizome seen 
9 in. long by 4-1 in. in diam., several arising from one point, cylindric, 
perfectly straight, rigid, spreading on the ground, and rooting beneath 
nearly their whole length, covered above by shining scales }—} in. long. 
Stem 1 from the end of each rhizome, 4-12 in. long. Leaves 4 by $ 
in. Head 1, 4-} in. in diam., of 50 spikelets, yellow; bracts 3, the 
lowest 14 in. long, similar to the leaves, dilated at the base. Spikelets 
(young) 3~-} in. long, 3-1-flowered; lowest flower 2-sexual, second 
flower male. Glumes elliptic-oblong, much inrolled, smooth. Style- 
branches 3, long, linear.—K. Schum. in Engl. Pfl. Ost-Afr. C. 122; 
Durand & Schinz, Etudes Fi. Congo, i. 291. C. obtusiflorus, var: 
stylo 2-fido, Ridley (errore) in Trans. Linn. Soc. ser. 2, Bot. ii. 132.

This extraordinary species K. Schumann proposes now (l.e.) to arrange in Mariseus, 
probably becanse of the few flowers to the spikelet. I have seen no ripe spikelets 
and leave it here for the present; the rhizome is exceedingly like that of Cyp- 
angolensis.
