• Into the Swamps with Woody Plants, Ruth Flanigan, 1990.

Every year for the past twenty-six, forest ecologist Burton Barnes and botanist Herb Wagner have offered U-M students in Woody Plants a botanical liberal arts education in introductory plant biology, ecology, and evolution. Woody Plants turns out students every fall who can identify more than 150 trees and shrubs, not by such easy but transitory features as deciduous leaves, but by persistent winter characteristics - trusty "clustered buds" and "warty lenticels."
