6. A. rhombifolia, Berith. in Hook. Journ. Bot. 1844, 87. A small 

 tree; extremities at first rusty-puberulous early glabrous, striate. 

 Leaves as broad as long, rachis puberulous, 2-3 in. long, with a sessile 

 gland between each of the 2 or 3 pairs of pinnae, and between all or 

 most of the leaflets ; leaflets 4-6-jugate, obliquely elliptic-oblong or 

 subrhomboid, obtuse, glabrous at length or obscurely ciliolate, rather 

 coriaceous, reticulate, the upper rather larger, 1-1 J in. long, § in. more 

 or less broad, subsessile. Flowers glabrous, " white," shortly pedicel- 

 late ; heads on erect axillary, solitary or fascicled peduncles 3-4 in. 

 long; pedicels 1-2 lines. Calyx rather broadly infundibuliform, 5-fid, 

 with ovate teeth. Petals united J-| their length, minutely hairy 

 above, externally scarcely twice as long as the calyx. United base of 

 the filaments included, adnate below to the petals. Ovary hairy, 

 stipitate. 



Upper Guinea. Senegambia, Heudelot! 



A single pinna, which may belong to this species, occurs in Speke and Grant's col- 

 lections (No. 760). 



7. A. glaberrima, Benth. in Hook. Journ. Bot. 1844, 88. Tree of 

 medium size; extremities at first pubescent. Pinnae 2-6-jugate; leaf- 

 lets 3-5-jugate, obliquely rhomboid-obovate, subacute, reticulate, gla- 

 brous, 1 in. long, more or less. Peduncles axillary, solitary or fascicled, 

 1 J in. long. Flowers capitate ; pedicels as long as flower. Calyx 

 tubular-campanulate, 5-toothed. Petals twice as long as calyx, 5-fid, 

 whitish. Staminal tube included. — Mimosa glaberrima, Schum. et Thonn.

Upper Guinea. Thonning. 



Description from Schumacher and Thonning. As Mr. Bentham suggests, this plant 

 may be conspecific with A. rhombifolia. The differences between them, though slight, 

 hardly justify me in uniting them without a sight of Thonning's specimen. 



8. A. Lebbek, Benth. in Hook, Journ. Bot. 1844, 87. Tree ; extre- 

 mities wholly glabrous or puberulous. Leaf-rachis 3-9 in., with a large 

 sessile gland near the base, with usually one or more interjugal glands ; 

 pinnae usually 2-4-jugate, leaflets 3-9-jugate, elliptic-oblong, or the 

 upper more oblique and obovate-oblong, very obtuse or retuse, sub- 

 sessile, glabrous, reticulate, 1-2 in. long, J-} in. broad. Peduncles 

 2-4 in., fascicled from the upper axils or corymbose ; flowers glabrate 

 or puberulous, capitate, on pedicels of 1—3 lines. Calyx 1J-2 lines 

 long, with short deltoid teeth. Free extremities of petals ovate-lan- 

 ceolate. United base of the filaments included. Legume |— 1 ft. long, 

 1-1 j in. broad. — Acacia Lebbek, Willd. Sp. PI. iv. 1066. For further 

 synonymy see Mr. Bentham's paper cited above.

 gambia and Fernando Bo-are in the Kew Herbarium.
