the petioles and peduncles tawny-puberulous. Leaf-rachis ^-6 (-10) in. 

 long, with a conspicuous gland near the base, and usually 1 or more 

 above ; pinnae 3-4- (-5) jug-ate ; leaflets 4-8-jugate, obliquely ovate- or 

 oblong-rhomboidal obtuse or broadly pointed, base truncate parallel 

 with the rachis, midrib diagonal, glabrous, shining and reticulate above ; 

 usually |-1J in. long, the uppermost pair either longer or shorter than 

 those next below, varying to 2 in. in length. Peduncles 1-2 in. from 

 the upper axils or forming short leafless terminal corymbs, sometimes 

 or scarcely overtopped by the leaves ; pedicels very short or 0. Calyx 

 tubular, 5-dentate, J— ^ as long as the corolla. Petals united j, like 

 the calyx silky-puberulous. Staminal tube slender, 4-5 times as long 

 as the flower. Legume straight or slightly curved, obtuse, 4-5 in. 

 long, j-f in. broad ; valves thin, subcoriaceous. 



Upper Guinea. Gaboon river, Mann! (Extremities tawny-puberulous. Ex- 

 serted staminal-tube exceeding 1 in.) 



Lower Guinea. Golungo Alto, Dr. Welwitsch ! (Extremities glabrous. Exserted 

 staminal-tube 1 in. or less.)

A. Mozambicensis, Bolle in Peters' Mossamb. Bot. 4. 



Tree ; extremities obscurely 4-angular, with the petioles pubescent ; irregularly scat- 

 tered with small solitary slightly recurved blackish prickles. Pinnae 6-11-jugate, leaflets 

 small linear-oblong oblique, thinly ciliate multijugate. Flowers .... Legume 3 in. 

 long, 4 in. broad, 2-valved ; valves coriaceous, margins thickened. Seeds 10, oblong- 

 ovate, 3-4 lines long. 



Mozamb. Distr. Zambesi, Dr. Peters. 



This plant I do not know, and doubt if it belong to the genus. Perhaps an Acacia. 



Speke and Grant collected in Usagara, on their way from Zanzibar to the head waters 

 of the Nile, a leaf of a tree apparently allied to Zygia or Pithecolobium (the Zygia 

 No. 4 of their Appendix), the M'Koondee of the natives. It is a tree of large size. 

 Leaves agreeing well with those of Zygia, but the inflorescence is figured by Col. Grant as 

 pendulous and capitate, like that of a Parkia. The legumes are very long. " The natives 

 cover their poisoned arrows with strips from the long pod when they do not use leather." 

 I cannot identity the plant. 



17. PITHECOLOBIUM, Mart. ; Benth. et Hook. f. Gen. 

 Plant, i. 596. 



Flowers capitate (in African species), usually 5-merous. Calyx 

 tubular or campanulate, denticulate. Petals united beyond the middle. 

 Stamens indefinite, exserted; filaments united at the base; anthers 

 small, pollen said to be as in Albizzia. Legume (in following species) 

 compressed, coriaceous, circinate, constricted between the seeds, "inde- 

 hiscent or separating in 1 -seeded articles." — Trees or shrubs, unarmed 

 or with stipular or axillary spines. Leaves bipinnate, leaflets various. 

 Inflorescence capitate (or spicate), axillary (or corymbose, racemose or 

 panicled at the extremities). 



A large genus, principally Tropical American and Asiatic. The only satisfactorily 

 determined Tropical African species belongs to Mr. Bentham's Section V. Cathormion 

 (Hook. Journ. Bot. 1844, 197).
