and two dorsal concentric rows of tubercular spines, with trans- 
verse radiating grooves between the spines. Pericampylus, in 
the structure of its putameu and seed, differs as widely from 
Cocculus 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 the thick 
foliaceous cotyledons of Cocculus, where they are greatly broader 
than the short terete radicle.
