This is one among the remarkable forms of Asclepiadeous 
plants, a native of New Spain, where it was first detected by 
Pavon (whose name it bears). It has the habit of Gonolobus or 
some other climbing member of the family, with flowers so much 
resembling a Stapelia, or rather a Huernia, that it is said to 
bear the name of Stapelia campanulata i Pavon’s MSS. We 
received our plants from Messrs. Henderson, of St. John’s Wood 
Nursery, and also from Messrs. Rollisons, of Tooting. It re- 
quires the heat of the stove, and flowers copiously in September. —
