the lowest § spikelet ; rhachis-joints and pedicels flat with densely 
shortly pale fulvous hairy margins; spikelets reddish ; sessile 
spikelet exceeding the rhachis-joint, callus short, blunt with a 
subequal tuft of hairs on each side, oblong-lanceolate, broadest. 
in the middle; outer glume coriaceous, glabrous with a scarious 
scabridulous 2-denticulate apex, elliptical-oblong, margins con- 
volute, many-nerved, usually the 3 (sometimes 1 or 5) central 
nerves form conspicuous parallel ridges; gl. II. subequal, 
3-nerved, broadly navicular, blunt; gl. III. hyaline, oblong, 
tapering to a blunt apex, 2-nerved, margins inflexed ciliolate 
above; fertile glume hyaline, linear from a weak stipitiform 
base, apex bifid, awn 3 times the length of the spikelet, column 
brown, shortly villous, shorter than the pale subula; pale short, 
rounded, lodicules broadly cuneate, ovary glabrous; pedicelled 
spikelet lanceolate, acute, larger than the sessile; outer glume . 
inconspicuously many-nerved ; gl. II. slightly shorter, 3-nerved, 
narrowly navicular, mucronate ; gl. IIT. hyaline, oblong, blunt, 
3-nerved, flowering glume hyaline, narrow. , 
Specimen 2} ft. high, upwardly spreading, internodes terete, 
lower 1 to 13 in. long, becoming longer above; ligule glabrous 
1 to 14 lines long; the narrow subflattened leaf-blades reaching 
9 in. in length, 2} lines or less in breadth, much longer than the 
sheaths, Inflorescence a foot or less in length; ultimate spathes 
1} to 24 in. long, racemes # to 1 in. long (excluding awns), 
pedicels + line and 2 lines respectively ; scarious process beneath 
lowest § spikelet reddish, 2 to # line long. Rhachis-joint red 
2 lines long ; sessile spikelet 31 lines including the callus (4 line) ; 
point of insertion oblique, leaving no scarious appendage ; gl. III. 
23 lines: long ; fertile glume 2 lines, awn 9 to 10 lines, pale 4 
line. Pedicels 13 to 2 lines long, bearing ¢ spikelets 4 to 5 lines 
long, margins of flattened outermost glume narrowly incurved 
becoming carinulate above the middle, keels scabridulous; gl. II. 
33 to 4 lines, hyaline between the nerves; gl. III. 33 lines, the 
margin ciliolate in the upper 2; flowering glume scarcely 3 lines, 
margin ciliolate above. 
Near A. bracteatus Willd., but easily distinguished by habit, 
the markedly ridged outer glume of the sessile spikelet, and the 
shorter weaker awn.
