186 XXVIII. GRAMINES, [Setaria 
with narrow linear-lanceolate or linear-tapering flattened 
scabridulous 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 sete 
spring from below each spikelet; barbs on the sete ascending ; 
barren glumes membranous, colourless between the well-marked 
green veins ; gl. I. scarcely half the length of the spikelet, sub- 
ovbicular with an abruptly shortly apiculate apex, 3-nerved ; 
gl. II. broadly oval, with a broadly rounded back, 5-nerved ; 
gl. IIT. similar but a shade longer, blunt and flatter, subtending 
an equal flat pale anda ¢ 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 
height. The larger specimens have a short culm, with subecom- 
pressed internodes 1 to 2 in. long, and 14 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 2 line long ; blade tapering to a long fine 
point, 2 to 12 in. long by 14 to 3, or rarely nearly 4: lines broad. 
Panicle from less than | in. to 54 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 } to $ in. 
Glume I. from a little over 4 to } line long, closely embracing the 
base of the spikelet; gl. IJ. } line long, 5-nerved becoming 
7-nerved below the very bluntly apiculate apex; gl. III. 4 line 
long. Fertile gl. 2 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 setz.

4, §. paniciformis Rendle sp. nov. 
Apparently perennial, from a tough slender rhizome ; shoots 
tufted, subspreading, slender, simple or branched ; leaves long, 
narrow, acute, tapering gradually to both ends, flat, subplicate at 
the base; panicle dense, narrow lanceolate in outline, spikelets 
subsessile on the short ascending branches, or very short branch-
