subtending leaves like the preceding ones but with more filiform 
and shorter blades, these rapidly decreasing upwards and becoming 
almost setaceous. Spatheol.es very narrow, acute, scarious, 8-9 
lin. long, reddish, ' glabrous, early tightly in rolled ; peduncles at 
length exserted by 1-3 (rarely more) lin., very finely filiform, 
scaberulous upwards with slightly thickened tips. Racemes up to 
4 lin. long, lax with 1 or 2 sessile and 1-3 pedicelled spikelets or 
barren pedicels ; joints subcapillary, 1 to almost 2 lin. long, very 
shortly ciliate ; pedicels similar, sometimes more or less reduced and 
quite barren. Sessile spikelets linear-lanceolate, acuminate, 2-2^ 
lin. long, including the short subacute pale and short-bearded callus. 
Glumes equal, acuminate, glabrous and smooth except for the short 
scaberulous keels ; lower subcoriaceous, sharply 2-toothed, very 
faintly 7-9-nerved ; upper lanceolate-oblong, somewhat thinner, 
obscurely notched with a fine bristle not much over 1 lin. long, 
3-nerved. Lower floret reduced to an oblong obtuse nerveless 
ciliate purple hyaline valve. Upper floret 1 lin. long : valve 
2-fid to the middle, lobes lanceolate, acute, eciliate ; awn very fine, 
about 7-8 lin. long, kneed at and twisted below the middle, column 
dark, bristle pale, scaberulous ; valvule 0. Grain linear-oblong in 
outline, dorsally more or less compressed, 1 lin. long, deep purple 
to almost black. Pedicelled spikelets $ or neuter, similar to the 
sessile but slightly longer and acutely to setaceously acuminate, 
lower glume 7-9-, upper 5-3-nerved : both valves purple, very 
narrow.

4. A. longifolia, Stapf. Perennial (?). Culms (base unknown) 
up to 3 ft. high, erect, slightly compressed, particularly in the upper 
part of the internodes, firm, glabrous, very smooth, glossy, pale, if 
not whitish-pruinose below the nodes. Leaf- sheaths (upper) slightly 
compressed and keeled upwards, tight, firm, glabrous ; ligules very 
short, truncate, ciliolate ; blades erect, narrowly linear, passing 
gradually into the sheath, up to over 1 ft. by 1-1J lin., rather rigid 
and firm, with some soft long hairs above the "ligules, otherwise 
glabrous, smooth or almost so except in the upper part where they 
are more or less rough on the face and the margins, midrib slender, 
prominent below, lateral nerves fine, close, numerous. Spatheate 
panicle narrow, erect, stiff, compound, with very few branches of 
the third order, up to almost 2 ft. by 2-3 in., primary internodes 
about 10, the lowest 4-4 J in. long, the following gradually decreasing ; 
primary tiers of up to 3, rarely 4, very unequal rays or the lowest 
branches undivided at the base, the longest up to | ft. long, erect, 
slender, bearing about 6 distant secondary tiers of usually 2 unequal 
rays (sometimes one of them compound in the lowest part of 
the panicle, 2-noded) ; ultimate (simple) rays enclosed in or shortly
