358 XLVII. § MIMOSEZ (OLIVER). [ Albizzia. 
6. A. rhombifolia, Benth. 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—8 in. long, with a sessile 
gland between each of the 2 or 3 pairs of pinnw, and between all or 
most of the leaflets; leaflets a ee obliquely elliptic-oblong or 
subrhomboid, obtuse, glabrous at length or obscurely ciliolate, rather 
coriaceous, reticulate, the upper rather larger, 1-1} 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 }—3 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. Pinnwe 2—6-jugate; leaf- 
lets 8—5-jugate, obliquely rhomboid-obovate, subacute, reticulate, gla- 
brous, 1 in. long, more or less. Peduncles axillary, solitary or fascicled, 
1} 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 ; 
pinne 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, 1-3 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 14-2 lines 
long, with short deltoid teeth. Free extremities of petals ovate-lan- 
ceolate. United base of the filaments included. Legume }~1 ft. long, 
1-1j in. broad.—Aecacia Lebbek, Willd. Sp. Pl. iv. 1066. “For further 
synonymy see Mr. Bentham’s paper cited above. 
Upper Guinea. Said to be indigenous on the Gambia. 
gambia and Fernando Po are in the Kew Herbarium.
