Spikelets on the continuous ramifications of a compound panicle, the 
lateral ones in pairs, the terminal ones ternate, one sessile, one or two 
pedicellate, the sessile one hermaphrodite, with cartilaginous polis ed and 
generally colored outer glumes, the pedicellate ones male or neuter, with 
thinner mes, often reduced to mere pedicels. Flowering glume

+1. S. vulgare, Pers. Enchirid. I, 101. — Stem erect, 4—5 ft. , puberulous 
at the nodes. Leaves plane, over 1 ft. long and 1/g—1' baoas: glabrous, 
with rough margins, pubescent at the base. Ligule short ovate. Panicle 
contracted and crowded, 4—8‘ X 1—2‘, with suberect stiff rough and 
pubescent verticillate rays. Sessile apikelot broad ovoid, compressed, some- 
what obtuse, about 2“, its outer glumes pubescent at the top (in our variety), 
At yellow when mature, the first faintly 7—9-nerv rved, the second 3—5- 
rved; third and fourth glumes hyaline, the latter frequently awnless in 
ay lateral spikelets. — Andropogon auct. — Holeus Sorghum, 
The well known Sorghum or Guinea-Corn, eae for chicken feed and occasionally 
found escaped from cultivation. In Italy the is considered injurious to — 
an opinion not borne out by the experience of si raisers on this group. The Broo 
Corn is a variety of this species with a more open panl icle. 
+2. S. saccharatum, Pers. — Panicle larger, open, its rays longer and 
more remote from each other, naked in their lower portions, patent and 
nodding at last. Spikelets more pointed; their glumes dark brown or 
blackish when mature. — Andropogon auct. — Holcus saccharatus, L. 
he Sugar-Sorghum, mainly raised as fodder for cattle and horses. van! ——

is a native of India and tropical Africa and of cael recent introduction nor 
the Hawaiian Islands. 
13. SACCHARUM, L. 
Spikelets 1-flowered, awnless, surroun nded by long silky hairs, in in pairs, 
both fertile and sessile or one pedicellate, along the jointed rays of a large 
panicle. Two outer glumes largest, thin but rather stiff; third 
glume hyaline, without palea. Flowering tise and palea very small, 
thin and transparent. 
A small genus of tropical Asia and Africa.
