634 pentandria monogynia. Cedrela. 



part smooth. Bracies to the primary branches of the panicle 

 opposite, as in the Rubiacea ; the rest solitary under each di- 

 vision and subdivision. Calyx inferior, five-leaved ; leaflets 

 rather unequal and oval. Petals five, oblong*, obtuse, spread- 

 ing. Nectary acetabuliform. Filaments five, alternate with 

 the petals, and shorter than they, inserted under the nectary. 

 Anthers ovate. Germ superior, three-lobed, indeed almost 

 separable, three-celled ; ovnla about eight in each cell, widely 

 attached to the axis. Style length of the germ, three-groov- 

 ed. Stigma three-lobed. Berry drupaceous, having- the ap- 

 pearance of a pome, of a roundish, three-lobed form, very 

 fleshy, when ripe yellow, and almost smooth, size of a large 

 medlar, three-celled. Seeds several in each cell, shape vari- 

 ous, the most common roundish, reniform and considerably 

 compressed, attached to the partition. Integument single, 

 thick and of great hardness, in fact a perfect nut, exterior sur- 

 face brown and highly polished. Pcrisperm conform to the 

 seed. Embryo obliquely inferior. Cotyledons cOrdate, three- 

 nerved. Radicle oval, obliquely centrifugal. 



CEDRELA. Schreb. gen. N. 383. 



Calyx five-toothed. Corol five-petalled. Capsules five- 

 celled, five-valved. Seeds several in each cell, winged and 

 imbricated on a pentagonal receptacle. Embryo inverse, pe- 

 risperm scanty. 



This genus is very nearly related to Srvietenia, the chief 

 marks of distinction appear to me to be the number of sta- 

 mina, viz. in Cedrela five, inserted on five nectarial glands 

 which embrace the base of the germ ; in Swietenia ten, insert- 

 ed into the mouth of a sub-cylindrical nectarium, which em- 

 braces the whole of the pistillum. In both, the seed vessels 

 and seeds are very exactly alike.
