5. D. brachyptera, Baker. A wide-climbing" shrub (sometimes 

 80 ft. long) with finely velvety woody branches. Petioles 3-6 in. long ; 

 developed leaves upwards of a foot long with 5—7 obovate coriaceous 

 leaflets, conspicuously emarginate and mucronate, terminal 5-10 in. 

 long, 3-7 in. broad, upper surface glabrous, the lower densely clothed 

 with grey or ferruginous velvety tomentum. Petiolules \ in. long, 

 stipellate. Flowers fascicled in racemes sometimes a foot long or in 

 ample panicles with racemose branches. Pedicels very short. Calyx 

 2 lines deep, campanulate, grey-velvety, the deltoid teeth not reaching 

 a quarter down. Corolla pale rose, \ in. deep, the wings and deep keel 

 exceeding the oblong standard. Stamens all connate in a long tube. 

 Pod membranous, linear-oblong, 2J-3 in. long, 1 in. broad, glabrous, 

 1 -seeded, with a wing \ in. broad along the upper suture.

Calyx- teeth short or obsolete. Standard suborbicular, exappendicu- 

 late ; wings nearly straight, oblong, obtuse, free ; keel-petals like the 

 others, imbricated but not connate on the back. Upper stamen free or 

 rarely connate with the rest; anthers versatile. Ovary long-stalked 

 in our plant, 2-4-ovulate ; style short incurved ; stigma small, terminal. 

 Legume drupaceous, ovoid or obovoid, indehiscent. Seed solitary, 

 pendulous. — Strong trees. 



A moderately small genus, all the species American, unless our second, which is only 

 known very imperfectly and may not belong here, be peculiar to Africa.

1. A. inermis, H. B. K. Nov. Gen. vi. 385. A tree 20 or 30 ft. high 

 with firm woody branches, the young twigs slightly grey-pubescent. 

 Petioles 2-3 in. long; leaflets 9-13, the pairs more than an inch apart, 

 lanceolate or oblong or the terminal one obovate, 2-3 in. long, f— 1 in. 

 broad, bluntish or subacute, the base scarcely rounded, subsessile, tex- 

 ture subcoriaceous, both sides glabrous, veins not raised. Flowers in 

 pyramidal panicles sometimes a foot long, with distant spreading stalked 

 racemose closely-flowered branches. Calyx subsessile, silky, 2 lines deep, 

 the teeth very short. Corolla rose-coloured, 6-7 lines deep, the stan- 

 dard 3-4 lines broad, the ovary distinctly stalked, glabrous or slightly 

 ciliated, with 3 or 4 ovules. Ripe pod not seen, but in an undeveloped 

 state the pedicel exceeds the calyx and all but one of the ovules are 

 abortive. — Benth. in Journ. Linn.' Soc. iv. Suppl. 122. Andira racemosa,
