3. B. tamarindoides, Welw.; Benth. in Linn. Trans, xxv. 312. 
Much branched tree of 15-40 ft. in height; extremities pubescent, at 
length glabrous. Leaflets in 10-18 pairs, at intervals of 2-3 lines, 
sessile, coriaceous, obliquely oblong-lanceolate obtuse, the somewhat 
eccentric midrib often terminating in a minute mucro, base unequal, 
shortly pubescent or tomentose-pubescent or at length subglabrate, 
3—3in. long. Flowers subsessile, in short, dense, ferruginous racemes or 
glomerules in the upper axils, or more or less confluent in terminal 
oblong panicles of 1 or Qin. scarcely overtopping the leaves. Bracts 
ovate concave 1-1} lines long. Involucral bracteoles rotundate, con- 
cave, about 2lines long. Perianth reduced to about 5 obovate or 
oblong-ciliate scales, 1 line or less in length. Stamens ‘10, glabrous, 
filaments connate in a very short ring at base. Ovary subsessile, densely 
villous; ovules about 7. Legume oblong or from lanceolate to oblan- 
ceolate-oblong at right angles to the short stout gynophore of 4—}in., 
the ventral suture dilated and terminating in the more or less persis- 
tent, rigid, subulate, straight base of the style; valves thickly coria- 
ceous, at length smooth ; 3-3} in. long, 1-1} in. broad. 
Lower Guinea. Huilla, Angola, Dr. Welwitsch! 
To the same or a nearly allied species must be referred fruiting specimens collected by 
Dr. Welwitsch in Pungo Andongo (and—a leaf enly—by Speke and Grant on their 
way to the Victoria Nyanza), of which the leaves are 4-1 ft. in length, and the leaflets 
14-2 in. The legume does not materially differ. 
21. DIDELOTIA, Baill.; Benth. et Hook. f. Gen. Plant. i. 1003. 
Flowers smail, enclosed until expansion between a pair of concave 
valvate bracteoles. Calyx and corolla obsolete or reduced to subulate 
rudiments. Stamens 5, subequal, antheriferous; filaments filiform ; 
anthers small, ovate or elliptical, dehiscing longitudinally. Ovary sub- 
sessile; style filiform, stigma minute; ovules indefinite, biseriate. 
Legume undescribed.—Leaves shortly petiolate, bifoliolate, leaflets sub- 
coriaceous, glabrous, obliquely ovate-oblong or -lanceolate acuminate 
l-nerved. Flowers small in short dense racemes given off successively 
from an elongate, slender, leafless rachis. 
Based upon the following species peculiar to West Tropical Africa. It may prove 
congeneric with Brachystegia. 
1. D. africana, Baill. in Adans. v. 367 (note), t. 8. Outer margin 
of sessile leaflets at base broadly rounded, inner cuneate ; 4—5 in. long, 
2in. broad; petiole }-}in. long. Racemes pedunculate, cylindrical 
or ovoid, arranged alternately in slender compound racemes of 8 in. 
Upper Guinea. Gaboon, Griffon du Bellay. 
Ihave not seen a specimen. The description is from M. Baillon’s Memoir. 
22. TAMARINDUS, Linn.; Benth. et Hook. f. Gen. Plant. i. 581. 
Calyx-tube narrowly funnel-shaped, limb 4-partite, segments sub- 
equal in length, entire, imbricate, submembranous. Petals As pos-
