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, 

 \— | in. 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 2 in. scarcely overtopping the leaves. Bracts 

 ovate concave 1-1 J lines long-. Involucral bracteoles rotundate, con- 

 cave, about 2 lines 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 £-J 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 ; 3-3Jin. long, 1-1^ in. broad. 



Lower Guinea. Huilla, Angola, Dr. Web.oitsch! 



To the same or a nearly allied species must be referred fruiting specimens collected by 

 Dr. Welwitsch in Pungo Andongo (and — a leaf only — by Speke and Grant on their 

 way to the Victoria Nyanza), of which the leaves are ^-1 ft. in length, and the leaflets 

 l|-2 in. The legume does not materially differ. 



21. DIDELOTIA, Baill. ; Benth. et Hook. f. Gen. Plant, i. 1003. 



Flowers small, 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 

 1-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, 

 2 in. broad ; petiole J- J in. long. Racemes pedunculate, cylindrical 

 or ovoid, arranged alternately in slender compound racemes of 8 in. 



Upper Guinea. Gaboon, Griffon du Bellay. 



I have not seen a specimen. The description is from M. Baillon's Memoir. 



22. TAMARI3STDTTS, 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 3 (1 pos-
