FAMILY XLVIII. MELIACE^E. 



Trees or shrubs, the wood of which is often hard, coloured, 

 and sometimes sweet-scented. Leaves alternate, without stipules, 

 generally pinnate, 3-foliolate in Trichilia polyneura, 2-pinnate in 

 3Ielia AzcdcracJt ; leaflets entire. Flowers rather small, pani- 

 culate. Calyx 4-5-lobed, imbricate. Petals 4-5, imbricate, 

 convolute or valvate in bud. Disk various, sometimes incon- 

 spicuous, sometimes ring-like, or more or less enclosing the 

 ovary ; in Cedrela the disk forms a column to which both the 

 petals and the filaments are attached half-way from the base. 

 Stamens 8-10 (in Cedrela 5), filaments attached outside the base 

 of the disk, united more or less into a tube ; anthers sessile or 

 shortly stalked, attached on the inside of the tube, in Cedrela 

 the filaments are distinct above the attachment to the column. 

 Ovary 2-5-celled. Ovules in each cell usually 2, collateral or 

 superposed, in Cedrela and Swietenia 8-12; raphe ventral; 

 rnicropyle superior. Fruit a capsule or drupe. Seeds with or 

 without endosperm. 



Species nearly 600, natives of warm regions of America and 

 Asia, rarer in Africa. 



Stamens more or less cohering to form a tube. 

 Leaves pinnate. Fruit a capsule. 



Seeds winged 3. Swietenia. 



Seeds not winged. 



Capsule 3-2-valved or not opening. Leaves 



imparipinnate 1. TricJiilia. 



Capsule 4-valved. Leaves pinnate 2. Guarca.
