Photographic Key for the Microhistological Identification of some Arctic Vascular Plants

Abstract

Microhistological techniques are used in many studies of food habits in herbivores. A photographic key for the microhistological identification of 112 Arctic and Subarctic plant species is presented. Epidermal features used in the key are described and illustrated in a photographic glossary. Enough information is given on plant collection, fragment preparation, and feature identification to help users customize the key with additional Arctic plant species.
