The latter species sometimes attains a diameter of nearly a foot, but, in the forest, both are usually little more than shrubs.

Of the shrubs, the yew {Taxus canadensis) is the most characteristic species: usually this is common, and fre- quently it forms a dense tangle which excludes other plants in much the same way that the mountain laurel {Kalniia latifolia) does in the woods of southern New England. Sometimes, how- ever, the yew is entirely absent over considerable areas. The northern hazel-nut {Corylus rostrata) occupies a position in the forest here somewhat parallel to that held by the witch hazel in woods farther south. A few other shrubs are ordinarily represented by scattered specimens, namely: fly honeysuckle.
