346 xlvii. § mimose2E (oliver). [Acacia. 



Seeds rather closely packed, transverse, oblong, but slightly compressed, dark reddish- 

 brown, shining. Not improbably a distinct species. Pungo Andeago 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. Fl. 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. PI. 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 ^—1 ft. 

 long-, rachis puberulous or glabrate "with a gland near the base " ; 

 pinnse in 12-80 pairs ; leaflets 30-50-jugate, linear-oblong, obliquely 

 pointed, glabrous, 2-2-J lines long. Peduncles J-l in. long, involu- 

 cellate near the middle, fascicled 3-5 in each node along a leafless 

 terminal raceme J-f ft. in length. Flowers capitate. Calyx minute, 

 denticulate. Petals connate, 3-4 times exceeding 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 J., 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 ; 

 pinnae 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 

 \ or | their length, about half as long again as the calyx. ' Ovary sub- 

 sessile, glabrous, subtruncate above, with an obliquely inserted fili- 

 form style. Fruit unknown.

20.* A. Farnesiana, 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. 

 Pinnae -in about 6 (4-8) pairs ; rachis pubescent or glabrate, usuallv 

 with a minute,* sessile gland near the base j leaflets in 12-20 pairs, 

 linear-oblong, obtuse or broadly acute, glabrous or giabrate, 2-3 lines 

 long. Peduncles 1-3 from each axil, ^-1 J in. long, slender, pubes- 

 cent or glabrate ; bracts immediately under the globose head. Calyx
