 ing- branches, with a sessile often conspicuous gland near the base ; 

 pinnae 3-6-jugate ; leaflets 8-16-jugate, oblong obtuse r entire or mu- 

 cronulate, pubescent on both surfaces, paler beneath, nervure median,

17. A. fastigiata, E. Mey. Comm. 165. Tree ; extremities petioles 

 and peduncles rusty-pubescent. Leaf-rachis 3-6 in. long, with a 

 sessile gland near the base and usually between the uppermost pinnae ; 

 pinnre 4-7 -jugate; leaflets 8-15-jugate, oblong-trapezoidal, sessile, 

 subquadrate at base, obtuse, with a diagonal midrib, the uppermost 

 pair usually smaller than below, glabrous and often shining and reticu- 

 late above, pubescent beneath ; J-J in. long, J in. broad more or less. 

 Stipules deciduous, often on the flowering extremities 3-5 lines long, 

 obliquely ovate, pubescent. Peduncles 1-2 in. long, axillary or fas- 

 cicled from leafless sometimes stipulate nodes, usually more or less 

 corymbose at the extremities or on short lateral branches. Flowers 

 pubescent or sericeous, subsessile or shortly pedicellate. Calyx nar-
