Ecology & Natural History

Habitat: Species is found in somewhat greater ecologic amplitude than typical M. canadense. It is often found in association with Acer saccharum, Fraxinus americana, Prunus virginiana, Quercus rubra, Tilia americana.

ILPIN Notes: This variety has leaves glabrous beneath; margins are entire or very minutely crenulate; transverse veins usually well-developed. This variety blooms about 2 weeks ahead of variety interius. The cherry-red berries in small terminal clusters last over winter & have a not unpalatable bitter-sweet taste, but being somewhat cathartic, like the berries of Smilacina. Should be eaten with caution. This variety is pubescent beneath on leaves; distinctly ciliate and transverse veins are poorly defined. Species blooms about 2 weeks after var. Canadense. Species is found only in northern 1/4 of Illinois.
