 irregular stigmatiferous head with two or three unequal lips. In 

 the ovary cell is seen, near the summit, a parietal placenta support- 

 ing two collateral descendent anatropous ovules, with dorsal raphe, 

 the micropyle du-ected inwards and upwards under the point of 

 attachment. The fruit (fig. 332, 333) is a lai-ge elongated apiculate

drupe, covered with hairs or points which often fall fijially. Its stone 

 is hard, prolonged above in a summit crowded with resinous vesicles, 

 and hollowed below in a mouospermous coll. The descendent seed 

 contains, under a thin subpulpy skin, a fleshy, corrugated and mul- 

 tilobate albumen granular outwardly, covering all over with a thin 

 layer, the very large foliaceous cotyledons with which it is several 

 times folded upon itself The radicle is superior, short and thick, more 

 or less swollen into a cone or sphere. P/z/jtocrene consists of shj-ubs 

 of Asia and tropical Oceania. The stalks, whose development may 

 be enormous, are sarmentous, climbing or volubile, often covered with 

 hairs or prickles. The alternate petiolate leaves are entire, minute or 

 palmilobate, 3-7-ncrvate at the base, often loaded with a very pro-
