21. PERICAMPYLUS. 
This genus was proposed by me in 1851 for a small group of 
East-Indian plants, the type of which is the Cocculus incanus, 
Coleb. It has been adopted by the authors of the ‘ Flora Indica,’ 
who remark that “it has the fruit of Cissampelos or Stephania, 
with the flowers of the tribe Cocculee; the 2-partite style and 
the peculiar inflorescence distinguish the genus.” The authors 
of the new ‘Genera Plantarum’ go so far as to state that it is 
not sufficiently distinct from Cocculus. This opinion has evi- 
dently been formed under a complete misconception of its struc- 
ture, as the facts here adduced will show: they would have been 
much nearer the truth if they had so contrasted it with Meni- 
spermum. Pericampylus differs from the latter genus in its 
nearly palate leaves, in the isometrical number of its floral parts, 
in its larger spathulate sepals, in the large, fleshy, globose or 
clavate termination of the filaments, where they are suddenly
