14. A small or moderate-sized tree, glabrous, with the young shoots gluti- 

 nous. Leaves crowded at the ends of the often pendulous branches ; leaflets 

 from 9 to nearly 30, lincar-Janeeolate, acute or mncronate, 1 to 1| in. long, 

 oblique, the midrib prominent underneath, but othenvise almost ner\'eless, 

 tne common petiole 3 to 6 in. long. Panicles narrow, shorter than the leaves. 

 Flowers nearly sessile, in clusters or on short branches of tlie panicle. Sepals 

 about 1 line loug. Petals about 2 lines. Teeth of the staminal tube subu- 

 late, but more or less connected by an undulate crenate or almost fringed 

 inembrane. Disk small, annular. 'Ovary 3-celled. Dnipe ^ to 1 in. or 

 I'ather more in diameter, said to resemble' a russet apple, the epicarp pulpy,
