flat pentagonal stigmatiferous head, with salient oppositipetalous 

 lobes. In the internal angle of each cell is a placenta supporting 

 two vertical series of ovules finally descending,' with micropyle in 

 this case directed upwards and inwards. The fruit is fleshy,^ nearly 

 globular, and surmounted by the remains or the scar of the calyx ; 

 it encloses, imbedded in its pulp, a variable number of seeds, the 

 coats of which cover a thick reniform embryo, with fleshy plano- 

 convex cotyledons and short radicle lodged in the hilum. Napoleona 

 comprises trees from tropical western Africa, with alternate glabrous 

 penninerved leaves, without punctuations and without stipules,^ and 

 axillary flowers,* solitary or in few-flowered glomerules, nearly sessile, 

 surrounded by short alternate imbricate bracts, glanduliferous like 

 the sepals, the shorter the lower they are. Six or seven species have 

 been distinguished ; there is perhaps only one.^ 



Asteranthos brasiliensis,^ a tree of Para and Guyana, with alternate 

 leaves, has nearly all the characters of Najpoleona ; it differs in its 

 expanded gamosepalous calyx, dentelate at the margin ; a much 

 longer style, with stigmatiferous head much less dilated ; elongate 

 ovules, much more numerous, in a semi-inferior ovary. Within the 

 corolla and united inferiorly with it, are a great number of stamens, 

 with slender filaments and introrse bilocular anthers. 



"VI? POMEGEANATE SEEIBS. 



In this genus,''' which has served as a type for a distinct family, 

 the flowers (fig. 334-338) are regular, hermaphrodite, with concave 

 receptacle, obconical or nearly so, the bottom of which is filled with 

 the adnate ovary, whilst the margin bears the perianth. The latter
