Kweichau communicated to Kew by Mer. Léveillé, Perpetual 
Secretary of the Academie Internationale de Géographie Botanique, 
was found excellent and abundant material of the same species 
in flower and fruit. 
Even with the complete series of specimens now available, 
approximately close allies have not been found, but it has been 
placed provisionally, as a new genus, among some anomalous mono- 
typic genera in Celastraceae. The name Dipentodon, proposed for 
it, refers to the most remarkable character possessed by the flowers 
in the exact similarity of the calyx teeth and petals (if I rightly 
call them so) and their insertion so nearly in one whorl that the 
appearance is given of a ten-toothed perianth.
