nate longer, glandular at apex, imbricated. Stamens 5, alterni- 

 petalous (in female flower sterile) ; filaments inserted outwardly 

 below liypogynous 5-agonal disk, subpetaloid at base, ciliate or 

 villous, interior naked or with 2 lateral scales, more or less high, 

 stipate ; anthers introrse, 2-rimose. Germen very shortly stipitate 

 beyond disk (in male flower rudimentary), 3-agonal, 3-locular ; 

 styles short, 3-lobed, inwardly stigmatiferous, sometimes reflexed 

 at apex ; ovules in each cell solitary or 2 -nate, inserted below apex 

 at internal angle, descending ; micropyle introrse, superior; raphe 

 dorsal. Fruit samaroid, with linear-oblong nucleus, subdrupaceous, 

 3-winged ; wings vertical, finally dry ; putamen hard, 3-agonal, atte- 

 nuated on both sides, traversed by resiniferous channels ; cells 3, 

 1-spermous (or abortive 1,2). Seeds somewhat terete ; testa fibrous ; 

 albumen fleshy ; embryo straight ; radicle very short, superior ; 

 cotyledons linear-oblong. — Trees ; l trunk simple ; leaves alternate, 

 imparipinnate ; folioles multijugate, alternate, linear-oblong or falci- 

 form, entire or serrate, glanduliferous at margin ; flowers 2 in large 

 terminal elongated cymiferous racemes ; bractlets very small 3 

 (Western, India 4 ). 



106? Picrodendron Pl. 5 — Flowers "dioecious;" male . . .? Fe- 

 male flowers 5-merous ; sepals small and petals (?) same in number, 

 alternate, laterally glandular. 6 Germen free, 2-locular; style 

 branches 2, linear, at apex stigmatiferous revolute ; ovules in cells 

 2, collaterally descending ; micropyle extrorse, superior, blocked 

 by rather thick obturator. Drupe 1-spermous (one cell effete) ; 

 " putamen finally sub-2-valved ; seeds sulcate, exalbuminous ; testa 

 membranous, insinuated between folds of embryo ; cotyledons 

 plicate ; radicle superior." — A small very bitter tree ; leaves alter- 

 nate, 3-foliolate ; folioles entire; flowers " male amentaceous axil- 

 lary;" 7 female axillary, solitary, pedunculate 8 (Cuba 9 ).
