[Anadelphia. 
including the callus ; callus short, acute, with a white or pale- 
fulvous beard of its own length. Glumes equal, acuminate, glabrous 
below the scaberulous acumen ; lower thinly coriaceous, 2-toothed, 
4-5-nerved, the nerves running into the scaberulous keels distinct, 
the others very faint, back slightly convex, smooth, scaberulous 
upwards ; upper glume linear-oblong, firmly membranous, obscurely 
2-toothed, with a fine bristle 2-2-| lin. long from between the teeth, 
1 -nerved, glabrous. Lower floret reduced to a linear-lanceolate 
acute hyaline nerveless valve, almost as long as the glumes. Upper 
floret 1 J- 1-2 lin. long : valve linear-oblong, 2-fid to one-third or 
half, lobes acute, glabrous ; awn very fine, 4-6 lin. long, kneed and 
twisted below the middle, column brown, scaberulous like the 
paler bristle ; valvule 0. Anthers f-1 lin. long. Pedicelled spikelets 
similar to the sessile, but the lower glume 7-9-nerved and the 
upper muticous or sometimes obscurely setigerous, 3-5-nerved ; upper 
valve entire, awnless, 1 -nerved. — Anadelphia virgata, Hack, in Engl.

Hackel, in DC. Monogr. Phan. vi. 396, has suggested that this may be 
Diectomis fasciculata, Beauv., Agrost. Expl. planch. 15, t. xxiii. fig. 6. Whilst 
the figure leaves no doubt as to its generic identity, the identification of the 
species is somewhat uncertain. Assuming, however, that Beauvois’ figure 
represents a part of a panicle, magnified about 2-2^ times, as is very likely, 
and allowing for a certain heaviness of the engraving and an exaggeration of 
the dentation of the glumes, the resemblance to A. leptocoma is indeed very 
great. Unfortunately Beauvois’ specimen seems to have been lost. 
3. A. tenuifolia, Stapf. Perennial (?). Culms (base unknown) 
up to over 3 ft. high, slender, terete, erect, firm, glabrous. Leaf- 
sheaths (upper) terete, tight, firm, glabrous ; ligules reduced to a 
ciliolate rim ; blades filiform-linear, passing gradually at the base into 
the sheath or narrower than the same, up to 6 in. by less than 1 lin., 
flexuous, hirsute towards and bearded at the base, otherwise glabrous, 
slightly rough above and on the margins upwards, midrib prominent 
below, whitish above, lateral nerves close and more or less prominent. 
Spatheate panicle narrow, erect, compound with very few or no 
branches of the third order, up to over 1J ft. by lJ-2^ in. ; primary 
internodes 8-9, the lowest up to over 5 in. long, the following gradually 
decreasing ; primary tiers of up to 4 very unequal rays or the 
lowest 1 or 2 branches undivided at the base, the longest rays of the 
lower tiers almost up to 1 ft. long, suberect, very slender, bearing 
5-7 secondary tiers of up to 4 nearly always simple rays, these like 
all the upper simple rays £-§ (rarely 1) in. long, finely filiform, scabe- 
rulous, not or very shortly exserted from their spathes ; lowest
