Illustrated Companion to Gleason and Cronquist's Manual
Consists of 827 plates containing meticulously rendered b&w botanical illustrations arranged and labeled to cross-reference with Gleason and Cronquist's 1991 Manual of Vascular Plants of Northeastern United States and Adjacent Canada, 2d ed.
The artwork is based on the original material of the New Britton and Brown Illustrated Flora of the Northeastern United States and Adjacent Canada , published in 1952, with substantial revision, rearrangement, and improvement. New illustrations of several species not treated in the earlier work are included, as well as useful diagnostic details not previously presented. Annotation c. by Book News, Inc., Portland, Or.
