solitary or 2-5 together in the axils : pedicels slender, 1-2.5 cm. long: calyx-lobes trian- 
gular or ovate, obtuse, usually slightly shorter than the tube: corolla funnelform, pur- 
plish becoming greenish, about 1 cm. long ; lobes ovate or oblong-ovate, spreading : sta- 
mens slightly exserted : berries oval, orange or orange-red. : 
In thickets, fence rows or waste places, Ontario to Minnesota, Georgia and Kansas. Naturalized 
from Europe. Spring and summer. MATRIMONY VINE.
