Specific Character. 
_ Cynancuum viridiflorum ;  volubile, foliis cordato-ovatis 
acuminatis, umbellis subsimplicibus solitariis, pedicellis, 
pedunculo communi longioribus. 
We have not been able to find a description of any species 
of Cynanchum, that agrees with our plant, nor is there any 
one in the very extensive Herbarium of Sir Joseru Banks, 
that corresponds with it. We are therefore constrained to 
take it up as an undescribed one. 
It has a twining stem extending several feet, producing 
umbels of green flowers with a flesh-coloured ring in centre, 
which grow from the middle of the stem between the 
petioles. The proper pedicles supporting the flower are 
mostly simple, but sometimes divided, unequal, longer than 
the petiole or common footstalk. Lacinie of the corolla re- 
curved. Native country not quite certain, but believed to 
be the East-Indies. Requires to be kept in the stove, where, 
if it can find support, it will extend many feet. May be 
propagated by cuttings. - 
_We have not seen this plant any where but in the collection 
of the Comtesse de Vannes, at Bays-Water, by whom it was 
communicated in November 1815.
