The variety scabra, Decne., is a condition with scabrous leaves, but sometimes 
scabrous leaves and the ordinary puberulous leaves occur on tlie same stem, 
Cynanchum hastatum, Pers, Syn. i. 273, and C. lanceolatum, Poir. Encycl. 
Suppl. ii. 430, Roem. & Schult Syst. vi. 111, are referred by Decaisne to this 
species, but I doubt if the identification is correct, as Persoon describes the flowers 
as subsessile, which they are not in this plant ; Poiret does not appear to have seen 
Persoon’s specimen, but has merely copied his description and changed the name.
