The Cynanchum difcolor is very nearly related both to 

 taTolinenfe and fuberofum, efpecially to the latter, from which 

 11 Js principally diftinguifhed by the common peduncle being 

 longer than the petiole, and hairy, which mfubero/um is fhorter 

 ar >d villous. From carolinenje it differs, in having longer, 

 narrower, and lefs obtule petals, and in its leaves being larger, 

 broader, more hairy, and of a darker green colour. 



Native of Virginia and Carolina in North-America. We 

 have no where feen this rare plant but in the very extenfive 

 c olieQion of Meffrs. Lee and Kennedy, at Hammerfmith, 

 where our drawing was made in Auguft. Jt is probably a 

 efficiently hardy perennial to bear the cold of our ordinary 

 timers.
