Obs. Of this vast nnd beautifal genus, 429 species are described by Mr. Bentbam in the Tro- 

 droQius of DC. Part vli., pp. 613 — 693. AH' these species have been cultivated in Europe, anil 

 in,irry in this country, but their successful culture is attended with more caro than that of moht 

 "tlior plants, and they have never as yet received general attention. To describe so few nyf- 

 cios as tha ^-.inits of this work would permit, where eo many are rarely and uone generally met 

 with, would be of little satisfaction to the student,
