ARCHIPELAGO: Port Chusan (Wilford, 922!), Port Chusan and

Sir Joseph Hooker, loc. sup. cit., confuses this with Cynanchum 
caudatum, Miq., and C. Bungei, Decne. (Symphyoglossum hasta- 
tum, 'Turez.), which are different from each other, and are readily 
distinguished from C. Wilfordi by their larger, strongly reflexed 
petals.

The coronal structure of this plant is almost exactly like that 
of Pentatropis spiralis, Decne., as figured in the ‘ Annales des 
Sciences Naturelles,’ 2"* série, ix. p. 327, t. 11. fig. E. 
The root, Dr. Henry states, is employed as a drug.
