Query: Excellent pocket guide!

This is a wonderful pocket guide for quick identification of species while hiking, etc. It proved invaluable during our recent inspection of our property and we could identify the various plants easily and quickly even though we were visiting "out of season" for most of the pics (usually in bloom, early June).HOWEVER, this is just a pocket guide, so the fact that the pics in the guide didn't show the plant in the season we visited didn't bother me at all. I simply double checked the pocket guide against their more complete referenceThe Nature of Alaska, 2nd: An Introduction to Familiar Plants and Animals and Natural Attractions (Field Guides - Waterford Press)which contains much more information, including "off season" identification.
