Reviews 65where the fine lines of division are sought to separate varietIes. It isof interest that the four specimens of P. contorta quoted fromAshford Castle are listed as P. contorta var. contorta rather thanvar. bolanderi. The author's comments and notes on various speciesand growth characteristics, distributed liberally throughout thetext add greatly to its value.Together with 24 full,page plates in~black and white the 203 linedrawings by Christine Darter are excellent and one wishes for moreof them-and in natural size rather than the off-putting two-thirdsscale size. The work is more likely to appeal to the initiated becauseof the nature of the subject but an extended glossary and an illustratedguide to the use of typical keys together with notes on thestandard method of measurement and confirmation that girth istabulated rather than diameter, as in the companion booklet, wouldwiden its considerable appeal in forest and estate circles andparticularly among students. No doubt the question of cost deterredthe publishers from providing a hard cover in a general edition, butfor those for whom this work will be an ever-flowing well of knowledgethe additional cost of having the booklet thus covered will bejustified.J.
