Cedrela, Linnaeus, Gen. PL 109 (1764); Bentham et Hooker, Gen. PL i. 339 (1862). 

 Toona, Roeraer, Synops. i. 131 (1846). 



Trees, belonging to the order Meliaceae, with unequally pinnate leaves, without 

 stipules, and composed of numerous opposite or sub-opposite stalked leaflets. 



Flowers in panicles, perfect, regular Calyx short, four- to five-cleft. Petals, 

 four to five, nearly erect, imbricated, free. Stamens, four to six, free, inserted at 

 the top of a four- to six-lobed hypogynous disc ; filaments subulate, anthers versatile. 

 Ovary sessile on the disc, five-celled, each cell containing in two series eight to 

 twelve pendulous ovules. Fruit, a coriaceous or woody capsule, composed externally 

 of five valves, and almost filled up internally by a central column, between which 

 and the valves are five thin cells, containing the seeds, which are numerous, 

 compressed, and with one or two wings. 



The genus is divided into two sections : 



I. Eu-Cedrela. Seed with a single wing on its lower side. Nine species in 

 tropical America. 



II. Toona. Seed with either two wings, one at each end, or with a single wing 

 above. Eight species in India, Indo-China, China, and Australia, all in tropical 

 regions except Cedrela sinensis.
