This variety seems to be widely spread in tropical America 
under the name African corn or Guinea corn. 
Gorunco ALTo.—8 to 12 ft. high, branched at the top, branches 
and main axis blood-red at the base. Cultivated by the river Cuango 
jn Arimo do Isidro; end of Sept. 1855. No. 7237. Native name 
Massambalo. 
Cazene@o.—A gigantic grass, 10 to 15 ft. or more, culm straight and

This species, hitherto unrecorded from the Old World, is repre- 
sented by two very distinct varieties. 
Var. angolense Rendle var nov. 
Panicle elongated, lax, flexuose, branchlets capillary, 1- to 4- 
flowered; spikelets submembranous, 3 lines long, awn pale, weak, 
subimperfect (showing no marked differentiation into column and 
subula), projecting 2 to 3 lines; outer glume lanceolate, narrowly 
truncate, pilose especially in the lower half, hairs white or faintly 
tinged with purple, callus with a tuft of similar hairs, 7- to 
9-nerved ; gl. IT. glabrous except the pilosulose margins, 5-nerved ; 
leaf-sheaths glabrous, blades linear, subscabridulous on upper 
surface, 2 lines broad or less, upper ones convolute ; ligule 
truncate, 3 to $ line long. 
Near Hackel’s wide-spread American var. avenaceum but dis- 
tinguished by its more membranous shortly awned spikelets, lax 
panicle, ete. 
Huitia.—Rather damp wooded meadows between Lopollo and 
Catumba ; Feb. 1860. No. 7491. Damp wooded grassy places near 
Catumba ; April 1860. No. 7496. 
Var. incompletum Hack., /.c., p. 531. 
_ The plants are larger, with spikelets a shade larger (2 to 24 
lines), and awns a trifle longer (14 in.) than in the Mexican plants, 
to which hitherto this variety has been confined, but otherwise 
similar and certainly inseparable varietally. 
Pungo Anponco.—An annual ceespitose grass, slender, with coarctate 
panicles, tawny gold and brightly shining when alive. Common in 
sandy woods near Quilanga ; middle of April 1857. No. 2821.
