MELIACEAE 



Leaflets abruptly rounded at the base, not 

 tapering into the petiolule; capsule ob- 

 long-obovoid, smooth. 

 Leaflets frequently inequilateral at the 

 base, tapering into the petiolule; capsule 

 cylindric, tuberculate. 

 Calyx cup-shaped, deeply lobed, 2-3 mm. 

 wide; leaflets 9-17. 

 Petals coherent at the base. 

 Leaflets thick -coriaceous, rigid, rather coarsely 

 reticulate-veined; petals slightly coherent at the 

 base. 

 Filaments distinct to the middle or below. 



Inflorescence usually sessile or subsessile, branching from 



the base, occasionally appearing panicle-like 



through the imperfect development of one of the 



lateral branches; calyx-teeth and petals usually 4. 



Flowers long-pedicelled, the pedicels longer than the 



short calyx-tube and loosely articulate with it; 



capsule not tuberculate. 



Filaments distinct to the base; lateral leaflets 



9-24 cm. long, 4-13 cm. broad, tapering into 



the long, often slender, sharp-acuminate apex. 



Filaments united below the middle; lateral leaflets 



3.5-15 cm. long, 2-6 cm. broad, rounded or 



obtusely short-acuminate at the apex. 



Flowers subsessile or short-pedicelled. the pedicels 



shorter than or about equaling the short calyx-tube 



and loosely articulate with it ; capsule tuberculate. 



Inflorescence long-peduncled; calyx-teeth and petals 



usually 5. 



Leaflets broad, the upper usually decidedly more 



than 4 cm., mostly of an obovate or oval type. 



Leaflets hispidulous especially on the midrib and 



lateral veins beneath. 

 Leaflets glabrous or merely puberulent beneath. 

 Panicles shorter or a little longer than the 

 petioles, usually narrow. 

 Leaflets abruptly obtusely short-pointed. 

 Leaflets acuminate at the apex. 

 Panicles several times as long as the petioles, 

 the branches long and spreading. 

 Leaflets narrower, usually decidedly less than 4 cm. 

 broad, often of an oblong, elliptic, lanceolate, 

 or ovate type, rarely obovate. 

 Leaflets 2.5-3 cm. long, 0.8-1.5 cm. broad. 



Young twigs densely hirsute; petals hirsute. 

 Young twigs appressed-pubescent; petals 

 glabrous. 

 Leaflets averaging decidedly larger. 



Panicles nearly or quite as long as the leaves, 



• broadest at the base, the lower branches 



much longer than the upper. 



Leaflets velvety-tomentose on both sides. 



Leaflets not velvety-tomentose on both 



sides. 



Terminal leaflet narrowly elliptic, 5.5- 



6.5 cm. long, 2-2.3 cm. broad. 

 Terminal leaflet obovate, 9-10 cm. or 

 more long, 3 cm. or more broad. 

 Panicles much shorter than the leaves, narrow, 

 the branches of approximately equal 

 length. 

 Capsule usually 2-Tjalved, the valves at 

 least as broad as long; leaflets velvety- 

 tomentose beneath. 

 Capsule usually 3-valved, the valves longer 

 than broad; leaflets usually nearly 

 glabrous, 

 "inflorescence corymbose-paniculate, subterminal ; ovary immersed 

 in a fleshy disk. 

 Leaflets glabrous on both surfaces. 

 Leaflets hirsute beneath. 

 Calyx of 5, free, strongly imbricate, orbicular, or suborbicular sepals. 

 Leaflets dull, the pellucid dots and lines obscure. 

 Leaflets lustrous, punctate with pellucid dots and lines.
