 species and narrow, not setiferous. — Nees in PI. Preiss. ii. 90.

 Sterns 1 to 2ft. high, quite flat or very slightly convex on one side, li to 2J lines 

 broad, the edges very acute, slightly scabrous. Leaves equitant, shorter than 

 the stem and about as broad. Panicle in the typical form erect, compound, 

 dense, oblong or thyrsoid 1^ to Sin. long. Outer involucral bract longer or 

 shorter than the panicle. Spikelets densely crowded and clustered, about 8 lines 

 long, with 1 or 2 barren flowers besides the perfect one. Glumes acute, the 

 inner ones acutely acuminate, the outer with shorter points, about 4 outer empty 

 ones gradually shorter. Scales or bristles at the time of flowering scarcely 

 dilated at the base, normally thickened under the nut into lanceolate scales with 

 a seta-like point often wearing away. — L. squamata, K. Br. Prod. 235 ; F. v. M.

 but most shorter. Panicle usually narrow and loose, 4 to Sin, long, the branches-

 long, with rarely more than 1 barren flower besides the perfect one. Glumes 

 acute and sometimes produced into short points but not aristate, 3 or 4 outer-

Spikelets variously paniculate, with 1 to 3 hermaphrodite flowers but usually 

 the lowest alone -fertile. Glumes few, imbricate all rouud, 1 to 8 or very rarely 



4 outer ones empty, and usually a small one above the perfect flower, either- 

 empty or with an imperfect flower, the flowering glumes not shorter than the 

 outer empty ones. No hypogynous bristles. Stamens 8 or rarely few-or. Style- 

 deciduous, sometimes, dilated at the base but continuous . with the ovary ;. 

 stigmatic branches 3, rarely 2, filiform. Nut ovoid or oblong, terete or obtus^ 

 triquetrous, smooth but rarely shining, crowned by the adnate base of the style
