2^^ CLv. RESTiACE^ (brown). [Hypolceua.

XlCozaznb. Bist. British Central Africa : Nyasaland ; Zomba, Mahon ! 



Besides the above, the Kew Herbarium contains a flowerless specimen collected in 

 Nyasaland on Mount Mlanji, at 7000 ft. alt., McClounie, 28 ! It may be the same 

 as the species above described, but the stems and branches are stouter, the sheaths 

 5-9 lin. long, and the plant itself appears to be of taller growth. Until flowering 

 specimens are procured it cannot be properly determined. 



Order CLVI. CYPERACEiE. (By C. B. Clarke.) 



Flowers glumaceous, 2- or 1 -sexual. Perianth hypogynous, of 6 or 

 fewer small scales or bristles, not petaloid, frequently irregular or im- 

 perfect, often 0. Stamens 3-1, free, all anterior. Ovary superior, 

 ovoid, 1-celled; ovule 1, basal; style 1, linear (base often thickened), 

 branches 3 or 2, or very rarely (in Rynchospora and a few species of 

 Cyp&rus) very much shortened so that the style is subentire. Fruit a 

 nut. Seed obovoid or ovoid ; testa thin ; embryo minute, obpyramidal, 

 at the base of the (usually floury) albumen. — Herbs. Stems solid. 

 Leaves narrow, grass-like, usually very tough and inedible; sheaths 

 generally cylindric, entire, in some species of Eriospora split as in 

 grasses. Flowers 1 or many in spikelets (the axis of which bearing the 

 glumes being the rhachilla of the spikelet), which are 1- or 2-sexual, 

 with empty glumes either at the bottom or top or both. Spikelets 1 or 

 many or very numerous, solitary, or in clusters (such compound inflor- 

 escences usually designated spikes). Spikes or spikelets arranged in 

 corymbs or apparently in umbels or in various ways. 



Species about 3300, extending throughout the world, growing especially in damp 

 places.
