It must be observed, that our plant is not the Cynancaum 
migrum of Cavanittes and WuLLpENow, now Gono- 
Logus niger, but is generally known by the old name of 
AscLepias nigra, though it has been long ago observed to 
belong rather to Cynancuum than Asciepias, and will yet, 
not improbably, revert to Piiny’s name Vinceroxicum. 
A hardy perennial. Native of the south of Europe. 
Flowers from June to August. Communicated by A. Mac- 
LEaY, Esq. from his collection at Tilbuster Lodge, Surry.
