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 Cocculea ; 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 Merii- 

 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
