Tue Waved Cynanchum is more remarkable for novelty than beauty ; yet, as an addition to our volubi- 
lous exotics, it possesses sufficient elegance to render it worthy our attention: especially as climbing 
plants have of late years become quite fashionable in most of the best conservatories in the vicinity of 
London. 
As a species, we conceive it to be perfectly nondescript, although it should seem to possess several 
characters in common with Cynanchum reticulatum, and C. undulatum of Willdenow, &c. ; both of 
which are known to us, but are described as having ovate, or oblong, not heart-shaped leaves. 
C. reticulatum is also a native of the same country, the East Indies ; from whence seeds of the unda- 
’ tum were brought in the year 1803 by Captain Thomas Hardwicke ; and were raised in the collection 
of the Marquis of Blandford, at White Knights, Berks, where they flowered last July; when that 
nobleman obligingly communicated to us the specimen from which the annexed figure was made. 
The Waved Cynanchum is a hot-house plant, and requires nearly the same treatment as Pergularia 
minor of our 184th plate,
