MENISPERMACEtfl. 5 



ten or twelve to twenty-five or thirty. 1 The fruits are bowed, laterally 

 compressed, and the reniform stone has a slightly prominent dorsal 

 crest, and is concave laterally with imperforate internal prominences 

 on both sides. Only two species of this genus are known, one from 



Menispermum dahuricum. 



East Asia, 2 the other North America; 3 both are cultivated in 

 Europe. Their broad leaves are often slightly peltate and palmati- 

 lobed, or with angular incisions. 



Abuta 1 ' has also nearly the flower of Cocculus, but without petals. 

 The three inner sepals are the larger, sometimes petaloid and valvate 

 or imbricated. The fruit is elongated, divided by a thin vertical 

 septum across which the seed is folded ; the embryo is transversely 

 ruminated. The genus consists of seven or eight species 5 of lianas, 

 from Tropical America, whose coriaceous leaves are 5-7-ribbed at the 

 base. The flowers form racemes, simple or slightly ramified in the 

 female plants, much more branched in the males.

 three grooves, which in water become narrow 

 bands. (H. Mohl, in Ann. Sc. Nat., ser. 2, iii.
