This document describes an interactive key for identifying species in the genus Galanthus, commonly known as snowdrops. It contains 19 species and numerous hybrids and cultivars. The key uses three main identification elements: leaf vernation, markings on the inner perianth segments, and leaf surface color/texture. It demonstrates the use of the key by providing details on an unknown specimen that is identified as G. ikariae based on its supervolute leaves, single apical marking, and description of large air spaces inside the leaves.
