TVTiilst the ovary cells are uniovulate in the preceding genera, 

 they each contain two or more ovules in the following types of which 

 the best known by us is Ka'lrcuteria (fig. 385-390). In this beau- 

 tiful tree from North China, propagated by our florists, u-regular

flowers are also observed, having five sepals, with thi'ee or four ungui- 

 culate petals, five to eight doclinate stamens, and a unilateral disk ; 

 but in each ovary cell is inserted, towards the middle of the internal 

 angle, two ovules primitively ascendent, with the raphe internal, 

 whilst Avhen full grown, only one remains so, the other becoming 

 descendent, with the raphe outwards. The fruit (fig. 387-388) is a 

 vescicular capsule, recalling that of CardiosperniKDt, whose three cells, 

 dehiscent by longitudinal dorsal clefts, are bleudcxl above and some- 

 times below. The exarillate seeds (fig. 389, 390) contain a fleshy 

 embryo, ^\'ith large cotyledons rolled in a spiral form. Stocksia, a 

 small shrub from the mountains of Beloochistan, is very different in 

 aspect, although it has the flowers organised very nearly the same,
