Decaisne {I. c.) defines six species of the group to which this 

 belongs, founded on forms which we should follow Maximo- 

 wicz in regarding as varieties of C. heraclecefolia, DC. The only 

 one easily separated from the others is C. Davidiana, which has 

 larger flowers clustered in the axils of the upper leaves instead 

 of a distinct terminal inflorescence. There are both wild and 

 cultivated specimens exhibiting these marked characteristics ; 

 but as the forms with distinct terminal inflorescence and smaller 

 flowers are collected with it, and have been regarded by collec- 

 tors as the same species, it is possible that C. Davidiana is the 

 male of the fully dioecious condition of the species. Maximowicz 

 also reduces the comparatively slender small-flowered C. stans, 

 Sieb. et Zucc, to this species ; and Sir Joseph Hooker (Bot. 

 Mag. t. 6S10), on figuring C. stans, Sieb. et Zucc, accepts this 

 limitation of the species, while defining five principal types from 

 China and Japan. Kuntze's classification {loc. sup. cit.) of the 

 forms differs slightly from Hooker's.
