346 XLVI1. § MIMOSEH (OLIVER). [ Acacia, 
Seeds rather closely packed, transverse, oblong, but slightly compressed, dark reddish- 
brown, shining. Not improbably a distinct species. Pungo Andongo and Golungo Alto, 
Angola, Dr. Welwitsch! This I take to be Acacia pentaptera of Dr. Welwitsch in 
Apont. Phyto-geogr. 584. 
Widely spread in Tropical Asia; occurring also at Natal. : 
Acacia pentagona, Hook. f. F). Nigrit. 331, is nearly allied to the above if not a 
mere form. The only specimen in the Kew Herbarium is very imperfect. It exhibits 
linear, longitudinally striate stipules, 2-3 lines in length, which, however, I have 
noticed in A. pennata. How far it may be correctly identified with Mimosa pentagona, 
S. and T. Pl. Guin. 324, I cannot say. The latter is described as a glabrous shrub, 
with scattered recurved prickles. 
18. A. amythethophylla, Steud. ; A. Rich. Fl. Abyss. i. 245. Tree 
of medium size; extremities puberulous. Stipular spines minute or 
stipules near the base of the shoots scarcely spinescent. Leaves 4—1 ft. 
long, rachis puberulous or glabrate “with a gland near the base” ; 
pinne in 12-30 pairs; leaflets 30-50-jugate, linear-oblong, obliquely 
pointed, glabrous, 2-24 lines long. Peduncles }$—1 in. long, involu- 
cellate near the middle, fascicled 3—5 in each node along a leafless 
terminal raceme }—$ ft. in length. Flowers capitate. Calyx minute, 
denticulate. Petals connate, 38—4 times nee the calyx. Legume 
(according to Dr. Schweinfurth) linear-oblong, flat, 4—6 in. long, 7—8 
lines broad, valves coriaceous, shining, obsoletely veined. Seeds 8-12.

I have only seen flowering specimens. Mr. Bentham reduces this plant to A. xipho- 
carpa, Hochst. (Lond. Journ. Bot. 1846, 96), but Dr. Schweinfurth, who describes the 
fruit, keeps it apart. I should probably have followed Mr. Bentham were it not on 
account of the racemose leafless inflorescence of A. amythethophylla. 
19. A. lasiopetala, Oliv. Extremities uniformly softly hoary-to- 
mentose. Stipular spines straight or subrecurved, pubescent nearly to 
the apex. Young leaves, especially on the rachis, silky tomentose ; 
pinne in 14—22 pairs; leaflets 20-30 pairs, probably often more nume- 
rous, not wholly developed in our specimens; gland sessile near the 
base of the rachis. Peduncles in pairs or solitary from the lower axils, 
pubescent, 1-2 in. long. Bracts obsolete. Flowers capitate. Calyx 
pilose-pubescent, lobes ovate obtuse. Petals externally silky, cohering 
4 or § their length, about half as long again as the an fee Ovary sub- 
sessile, glabrous, subtruncate above, with an obliquely inserted fili- 
form style. Fruit unknown.

20.* A. Parnesiana, Willd. ; Benth. in Hook. Journ. Bot. 1842, 494. 
Small tree or shrub; extremities glabrous or obsoletely pubescent, 
slightly zigzag from node to node. Stipular spines slender, straight. 
Pinne in about 6 (4-8) pairs; rachis pubescent or glabrate, usually 
with a minute, sessile gland near the base; leaflets in 12-20 pairs, 
linear-oblong, obtuse or eae acute, glabrous or glabrate, 2—3 lines 
long. Peduncles 1-3 from each axil, 5-1} in. long, slender, pubes- 
cent or glabrate ; bracts immediately under the globose head. Calyx
