370 Mr. J. Miers on the Menispermaceae. 



bent back extrorsely at a right angle, and upon which the 

 anther-cells are laterally imbedded, with a narrow and some- 

 times excurrent connective between them : it differs no less in 

 its excentric style, with a bifid or twice-bifid stigma ; in its pu- 

 taraen, which (although with a condyle like that of Menispermum) 

 has the whole of its external ring covered by two or three lateral 

 and two dorsal concentric rows of tubercular spines, with trans- 

 verse radiating gi-ooves between the spines. Pericampylus, in 

 the structure of its putameu and seed, differs as widely from 

 Cocculns as Menispermum has been shown to be at variance with 

 that genus — a difference which places Cocculus in a separate 

 tribe. The inner surface of the cell of the putamen in Peri- 

 campylus and the external corresponding face of the seed are 

 marked by broad radiating grooves, conformable with the spaces 

 between the external spines ; the embryo, as in Menispermum^ is 

 very long, uniformly very slender, quite different from ^he thick 

 foliaceous cotyledons of Cocculus, where they are greatly broader 

 than the short terete radicle.
