The Waved Cynanchum is more remarkable for novelty than beauty; yet, as an addition to our volubilous 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 undatum 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.[Pg 101]
