 warm countries. 



Stems 2-14 in. Spikelet Lin., pale. Bristles 7, or fewer. Nut as long as 

 f glume, compressed, obovoid. Visually easily distinguished from E. atropurpurea 

 by its larger size ; but small examples can hardly be separated except by the coloured 

 bristles (which are glistening-white in E. atropurpurea'). 



9. ZS. ovata, Br. Prod. 224 (in note) ; roots fibrous, steins somewhat 

 slender, spikelet small dense, bristles exceeding the nut retrorsely scabrous 

 brown, nut straw-colrd. or brownish smooth, style 2-fid base broad 

 triangular. C. B. Clarke in Journ. Bot. xxv. 268. Scirpus ovatus, Roth.

Very much resembles E. capitata, except in the colour of the nut, and the shape 

 of the style-base.

Rhizome black or chestnut. ' Stems 4-20 by -^g i ^ n> diam. ; uppermost sheath 

 truncate, on one side sometimes triangularly produced. Spikelet -1 by | in., 

 chestnut or straw-colrd. Glumes obtuse, persistent, keel green, lowest empty about 

 | surrounding or (in form uniglumis') almost wholly surrounding stem. Bristles 6, 

 as long as nut, retrorsely scabrous, rusty-brown, or (more frequently) reduced both 

 in numbers and length. Stamens 3, but in flowers near the tabescent top of the 

 spikelet, and in small depauperated examples, 2-1. Nut as long as glume, 

 unequally biconvex, obovoid, much narrowed at top, sometimes to a very short 

 beak j style-base contracted below on nut ; outer cells of nut quadrate-hexagonal 

 or shortly longitudinal oblong, obscure i.e. nut smooth ; or very rarely cells more 

 prominent, i.e. nut reticulated.
