or five parted isostemonous biovulate ovary and drupaceous fruit. 

 The leaves are alternate, compound-digitate, with one, two, or three 

 folioles. They are consequently very nearly allied to Amyris, but 

 present also close affinities with Toddalia. 



VII. AURANTEA SEEIES (Pr., Grangers). 



The Orange-tree [Citrus Aurantium) has given the French name 

 to this small group, but it presents a degree of complication in its 

 floral organization that does not permit of it being taken as the 

 type. We prefer to study as such a genus like Limonia 1 (figs. 452- 

 454), the flowers of which are regular and hermaphrodite, with 

 convex receptacle. The calyx 



has five Sepals free 01' United to Limonia (Glt/cosmis) eoeUnehinensis. 



a variable distance, and dis- 

 posed in the bud in quincun- 

 cial pignoration. The corolla 

 is formed of five alternate pe- 

 tals, imbricated in the bud. 

 The stamens are ten in number, 

 superposed, five to the divisions 

 of the calyx, and five, shorter, 

 to the petals. The filaments 



are inserted under a circular hypogynous disk, free, subulate, or more 

 or less dilated below, and their anthers are two-celled, introrse, de- 

 hiscing by two longitudinal clefts. The gynseceum is free, supe- 

 rior, formed of an ovary with five (more rarely of two, three or 

 four) oppositipetalous cells, surrounded by a style swollen at the apex 

 into a stigmatiferous head, often articulated upon the ovary at the 

 base, from which it is sooner or later detached. In the internal 

 angle of each cell a placenta is seen supporting one or two descending 

 ovules, collateral or superposed, with micropyle directed upwards 

 and outwards. The fruit is a plurilocular berry, one or several
