genera having usually the same flower, the petals of the former pre- 

 senting inwardly on their middle line an appendage or projecting rib, 

 which may exist ia the latter, or be replaced by numerous hairs. 

 The former has a biovulate unilocular ovary, like that of Mappia, with 

 a short conical style having the stigmatiferous apex dilated and 

 discoid. The latter has, on the contrary, in the ovary, three uni- or 

 bi-ovulate cells all eccentric, and put forth on the same side ; the 

 lateral two are often uniovulate. 



Lasimithera^ origuially from the warm regions of the old world, 

 forms the head of a distinct sub-series, in which the calyx is gamo- 

 sepalous, with divisions of more or less depth, as in the preceding 

 genera, but the seed is provided with a very small apiculate embryo, 

 having cotyledons very nearly as short as the superior radicle, and 

 furnished towards the summit with an abundant fleshy albumen. 

 In Lasianthera proper, the apex of the filament bears a long 

 bunch of penicillate glandular hairs, which are at first inflected 

 on the anther, whilst in Gomphaiidr<i these hairs are shorter and less 

 abundant. In lùiiiinicria, inhabiting tropical America, the flower 

 and fruit, with projecting vertical ribs, are very nearly the same, but 

 the petals have an interior projecting midrib, and a style immediately 

 dilated in a discoid stigma, analogous to that of Foraqueiba, the fruit 

 and embryo being those of Lasianfkera. In Pleur isanthes, a plant 

 from Guiana, the style is replaced by a bunch of papillae, the petals 

 are united in a cup detached by the base, the cells of the anther are 

 thrown out fr-om each side of the connective, and the flowers, small 

 and numerous, are sessile on only one of the faces of the axis, flat- 

 tened and as if fasciated by the inflorescence, exactly the same as in 

 certain species of Artocarpus, of which moreover this plant has very 

 nearly the aspect and foliage. In the Bcsmosfac/ii/s, climbing plants 

 from tropical western Africa and Madagascar, the flowers are very 

 nearly those of Lasianthera of the section Gomphamlra ; the stamens 

 have filaments, glabrous or loaded with short hairs, inserted on the 

 back of the introrse anthers, and the flowers are united in slender 

 and elongated spikes. 



With the general character of the j^receding genera, Apod//tes 

 and AnimmalloH present this singularity that Ihe adult fruits are bent 

 or thrown back after the manner of campylotropal and anatropal ovules,
