Upper floret ^ : valve stipitiform, shortly 2-toothed, awn slender, 
2-2 \ in. long, column fulvously hairy. Valvule 0. Anthers over 
1 lin. long. Pedicelled spikelets linear-lanceolate, reddish, 
glabrous, 3J-4 lin. long ; lower glume produced into a bristle up 
to 2 lin. long, closely 11 -nerved, tiers scabrid upwards ; upper glume 
acute, 3~nerved, reversedly ciliate ; valves hyaline, reversedly 
ciliate, the lower 3-nerved, up to almost 3 lin. long, the upper cuneate, 
emarginate, 1 -nerved, shorter; anthers over 1J lin. long. Homo- 
gamous spikelets like the pedicelled, but mutinous and usually slightly 
longer, — Andropogon familiaris, Steud. Syn. PI. Glum. i. 385 ;

Hens, A. 225, in the Kew and Paris collections, represents a mixture of H. 
familiaris and H. diplandra (?). Most of the pieces so numbered are evidently 
diseased (apparently affected by an Epichloe). In these the peduncles are 
glabrous and, compared with the spatheole, relatively shorter, whilst the 
spikelets are frequently enlarged (up to 6 lin. long), with irregularly developed 
florets, so that those which normally should be $ are either purely 6 or 6 with 
a rudimentary pistil, or neuter, whilst those which ought to be 6 (particularly 
of the homogamous pairs) are neuter. 
19. H. Ruprechtii, Fourn. Mex, PI. Gram. 67. Perennial, forming }jff 
dense caespitose clumps from a few to 10 ft. high, with intravaginal 
innovations. Culms rather' stout, terete, glabrous, smooth, some- 
times w^axy-pruinose, simple and 3-4-noded below the panicle. 
Leaf-sheaths terete, or those of the innovations compressed and 
keeled, glabrous, smooth, very rarely hirsute, the lowest more or 
less persistent, those of the culm-leaves produced at the mouth 
into a triangular or lanceolate auricle up to 14 lin. long ; ligules 
s carious, broadly ovate, rounded, glabrous, up to over 12 lin. long, 
laterally adnate to the auricles of the sheath ; blades linear from 
an equally wide or long-attenuated base, tapering to a fine point, 
up to over 1 ft. by 2 lin., rarely wider, somewhat rigid, with the 
margins frequently recurved, dull or glaucous green, rough on both 
sides, scabrid on the margins, glabrous or with some scattered 
spreading hairs towards the base, very rarely hairy all along on the 
under side; midrib somewhat stout downwards, broad and whitish 
on the upper side. Spatheate panicle erect, somewhat stiff, narrow 
and interrupted ; primary internodes 4-6, rarely 7 or more, the 
lowest about J ft. long, the following very gradually, the upper-
