Var. MACROPHYLLUS. Foliis rotundato-cordatis majoribus (nunc 9-10-polli- 

 caribus), acuniine abrupto, lobis basilaribus rotundatis sinuni sjepe claudentibus,

 macrophyllns, Miclix. 1. c. G. viridiflorus, Nutt. Gen. i. 163 ( G. Nuttallii, De- 

 caisne in DC.) G tiluefolius, Decaisne in DC. G. grunulatus, Scheele in Linnaea, 

 xxi. 759. Viiicetoxiciim gonocaipos, Walt. Car. 1U4, pro parte. — S. Carolina to 

 Texas, Kentucky and Missouri. Elliott's G. viacrofiliyllus, with muricate fruit 

 and slender lobes to the corona, must be G. Baldwhiidnus, Ciiapnian's is G. 

 mberosas, and Decaisne's, in the Prodromus, is mainly G. oUiquus. Pursh's 

 addition of " flowers dark purple or dirty yellow " was taken from Walter, 

 who evidently had more than one species under his Vincetoxicuin gonocarpos.
