186 XXVIII. GRAMiNE.E. [S'etaria 



Avith nniTOw linear-lanceolate or linear-tapering flattened 

 scabriclulous sometimes hairy leaves ; panicle spiciform and 

 narrowly cylindrical or subpyramidal to lanceolate in outline, 

 spikelets 1 line long, ovately oval, subplano-convex, glabrous, 

 densely crowded on the short branches which end in a rather 

 long and strong flexuose seta, one or a few shorter weaker seta? 

 spring from below each spikelet; barbs on the setse ascending; 

 barren glumes membranous, colourless between the well-marked 

 green veins ; gl. I. scarcely half the length of the spikelet, sub- 

 orbicular with an abruptly shortly apiculate apex, 3 -nerved ; 

 gl. II. broadly oval, with a broadly ■ rounded back, 5-nerved ; 

 gl. III. similar bvit a shade longer, blunt and flatter, subtending 

 an equal flat pale and a (^ flower ; fertile gl. oval, shorter than 

 the second and third barren glumes, coriaceous, convex, minutely 

 transversely rugulose. 



The plants, according to a note of Welwitsch, reach 4 to 6 ft. in 

 lieight. The lai-ger specimens have a short culm, with subcom- 

 pressed internodes 1 to 2 in. long, and 1^ to 2 lines wide ; from 

 the nodes spring densely branching lateral shoots. Internodes 

 stramineous, striate, glabrous like the nodes. Sheaths, except 

 the few uppermost, exceeding the internodes, rather loose, sub- 

 membranous, the upper narrow and closely embracing the inter- 

 nodes, glabrous or tuberculo-pilose especially near the mouth ; 

 ligule a fringe of hairs ^ line long ; blade tapering to a long fine 

 point, 2 to 12 in. long by 1~ to 3, or rarely nearly 4 lines broad. 

 Panicle from less than 1 in. to Sj- in. long, and 2 lines to 1 in. 

 across, rhachis and branches shortly hairy ; in the lower part of 

 the larger inflorescences the short branches reach I to fr in. 

 Glume I. from a little over I to ^ line long, closely embracing the 

 base of the .spikelet ; gl. II. ^ line long, 5-nerved becoming 

 7-nerved below the very bluntly apiculate apex ; gl. III. i line 

 long. Fertile gl. 'i line, inconspicuously 3-nerved, 5-nerved above ; 

 pale subequal of similar consistence. 



Near >S'. verticillata Beauv., but distinguished by its large 

 second barren glume, completely covering the smaller fertile 

 glume ; also by the ascending not reversed barbs of the setaj.
