black-gum

Black-Gum Nyssa sylvatica
Family: Cornaceae (Dogwood)
Branching: Alternate
Other Names: Black Tupelo, Sour-gum

This tree is rare in Ontario and only found in the most southern areas. It generally grows in moist forests and usually isn't a very big tree. It is one of the few trees that has a chambered pith (though for some reason I forgot to take pictures of the specimen here!) The mature bark becomes checkered and is often compared to "alligator skin". These pictures were taken in the early spring and the buds may be opening up slightly.
