Congratulations to Jim Eckenwalder on his just published book,
Conifers of the World: The Complete Reference, Timber Press.  This is a major work, with 720 pages, 67 color photos, 295 b/w photos, 240 line 
dr. and 67 distribution maps.

From the publisher: "Researched for more than three decades, this 
definitive work provides up-to-date descriptions of all the true 
conifers of the world, including 545 species of trees and shrubs. 
Written for accessibility to both horticultural and botanical 
audiences, it is the first comprehensive update of conifer taxonomy in 
nearly a century. Noted conifer taxonomist James E. Eckenwalder also 
discusses the relationships among the groups, practical usages, 
champion trees, fossil occurrences, and biology.  With its 
unprecedented attention to detail and extensive bibliography, this 
major work is an essential reference for botanists, naturalists, and 
horticulturists..."
