nearly glabrous, the latter spreading obliquely and when mature 
drooping. Sessile spikelets rhombic to subquadrate-obovate, straw- 
colour, mostly turning glossy black on maturity or black below and 
yellowish above, or brownish or yellowish, sparingly strigillose, 
awned. Grain exserted from the glumes, obovate-orbicular in out- 
line, dull white, 2J lin. by 2f lin. — K. Schum. in Engl. Pfl. Ost-Afr.

Busse & Pilger (l.c.) also refer to this plants collected at Sokode in Togo 
( Kersting , 12, 14, 15, & 20, a. 1900), but they say that these have narrower, 
relatively longer panicles (10-12) and larger grains, either white or scarlet. 
14. A. S., var. glaberrimus, Hack, in DC. Monogr. Phan. vi. 512 ; 
Durand & Schinz, Consp. FI. Afr. v. 725. Panicle oval-oblong, 
obtuse, compact , lower branches equalling about a quarter of the 
panicle, undivided for | in. or somewhat more. Sessile spikelets 
broad ovate-elliptic, acute, lin. by 2 lin., straw-colour with reddish 
spots, at length quite glabrous. Grain as long as the glumes, orbi- 
cular in outline, plano-convex and strongly gibbous, bright copper- 
colour.

Probably a colour form of S. caudatum, var. gibbum. 
15. A. S var. Hewisonii, Piper in Proc. Biol. Soc. Wash, xxviii. 
41. Culms stout, 13-19-noded, up to almost 12 ft. high, waxy 
below the nodes. Leaf-sheaths mostly overlapping ; blades up to 
over 3 ft. by lf-3|- in. Panicle fusiform, very compact, 4-6 in. by 
IJ-lf in., longest branches about 1-2 in. long. Sessile spikelets 
moderately persistent, broad-ovate or oval, 2f lin. by 1J lin., densely 
white-hairy, green except at the chestnut-red base, awned. Lower 
glume 9-11-nerved. Awn 5J lin. long. Grain obovoid, compressed, 
If lin. long. Pedicelled spikelets neuter, narrowly lanceolate, hairy.

Piper says that this suggests his “ cordofanus,’’’’ that is Sorghum cethiopicum, 
but the heads are much more dense, the awns smaller and the lateral spikelets 
without stamens ; differences which do not carry much weight from the point 
of view of classification. 
16. A. S ., var. hirsutus, Busse & Pilger in Engl. Jahrb. xxxii. 185. 
Panicle about 9 in. long, ovate-lanceolate in outline, a little narrower 
upwards ; rhachis stout ; lower branches IJ-lf in. long, erect, stiff, 
somewhat arching. Glumes ovate-lanceolate, acute, dark brown, 
greyish- whit e-strigillose, margins involute on maturity. Grain 
slightly compressed, white, shorter than the glumes.

Evidently a variety of the Roxburghii group.
