A. cordifolius polycephalus Porter. Many-iikadki) Astkr. Oc- 

 casional ; usually found with the type, llrai'es ; Lucy. More

 fretjuent. East Hill road near Elmira, Lucy. 



A. Lowrieanus Porter. Luwkik's Asikr. Not uncommon. Un- 

 til recently this species has been confused with ,/. cordifolius, 

 but is easily distinguished by its broadly margined petioles,

 state the leaves seem greasy to the touch. It will probably be 

 found throughout our range.
