densely and equally ciliate along both edges, cilia fulvous. Sessile 
spikelet oblong-linear, 4 lin. long, including the pointed densely 
and shortly bearded callus, which is 1 lin. long. Glumes equal ; lower 
coriaceous, chestnut-brown, shining, rounded on the back and sides, 
very indistinctly 2-keeled at the obtuse or truncate scaberulous tips, 
more or less appressedly pubescent below the middle, 7-nerved : 
upper oblong, rounded on the back, subcoriaceous, minutely 3- 
toothed, ciliolate upwards, 3-nerved. Lower floret reduced to an 
oblong truncate hyaline ciliate shortly 2-nerved valve. Upper floret 
^ : valve stipitiform, with 2 short very narrow and acute hyaline 
lobes at the base of the awn, which is about 3 in. long, kneed at and 
loosely twisted below the upper third, column straight or flexuous, 
brown or yellowish like the spreading or reflexed bristle, both 
minutely scaberulous ; valvule 0. Anthers If lin. long. Grain 
subcylindric, 2 lin. by f lin., purple. Pedicelled spikelet 
narrowly linear, tapering to an acute point, up to 5 lin. long, glabrous ; 
glumes somewhat unequal and chartaceous, greenish, the upper 13- 
nerved, the lower 11 -nerved, about 4 lin. long ; lower valve about 
as long as the upper glume, 5-nerved, ciliate, upper similar, slightly 
shorter, hyaline, sub-3-nerved ; anthers 2 lin. long.

47. MONIUM, Stapf. 
Spikelets all alike, solitary, awned, with an acute bearded 
callus, borne on and readily disarticulating from a very slender 
peduncle, supported by and permanently enclosed in a spatheole, 
the whole representing an extremely reduced monostachyum ; 
monostachya collected in a usually much contracted spathaceous 
panicle. Florets 2, lower reduced to an empty valve, upper £5. 
Glumes equal, coriaceous to subcoriaceous, both rounded on the 
back with involute margins (hence spikelets terete) ; lower 2-toothed, 
finely or obscurely 2-keeled towards the tips, very obscurely nerved, 
upper produced into a fine bristle from the notched tip, sub-8-nerved. 
Valve of lower floret hyaline, nerveless ; of upper narrowly oblong, 
2-fid, with a long very slender awn from the sinus, with the base, 
margins and lobes hyaline, otherwise subcartilaginous. Valvule 0. 
Lodicules 2, minute, glabrous. Stamens 3. Stigmas laterally 
exserted. Styles terminal. Grain cylindric, very slender ; scutei- 
lum elliptic, equalling one-third the length of the grain.-— -A delicate 
annual grass. 
Species 1, endemic. 
This and CleistacJme represent the most extreme cases of reduction in Andro * 
pogonece ; but as Cleistachne in the structure of its inflorescence and spikelets 
betrays its derivation from Sorghum, so Monium has preserved all the other 
essential features of Anadelphia.
