10. P. exilis, Roem. d- SchuUes, Syst. Veg. ii. 98. Annual, hairy. 



Stems tufted, 4-1 6 in. long, rather slender, usually with patent hairs 



scattered through their whole length, but sometimes nearly glabrous. 



Leaves J- J the. length of the stem, up to ^ in. broad, hairy or glabrate, 



«heaths always hairy. Umbel of 3-14 pedicelled spikelets; bracts 4-3, 



about as long as the umbel. Spikelets \-\ by \ in., 10-12-flowered, 



pale ferruginous « usually much tinged with chestnut. Glumes ovate, 



acute, pubescent ; keel green, excurrent into a mucro. Stamens 3-2. 



Style rather shorter than the nut, nearly glabrous ; branches 3 ; base 



dilated, subpyramidal, horizontally truncate, with a constriction above 



the nut. Nut rather large, often J the length of the glume, trigonous 



or triquetrous, obovoid or narrowed much at the base so as to be pyri-
