Key to Erythronium

A genus of about 25 species, north temperate and subarctic, of North America and Eurasia (especially diverse in w. North America).

Glossary (beta!)

ID notes: Erythronium is characterized by one to two leaves borne at ground level, and a yellow or white, single flower on a scape. The leaves are mottled green and brown in most species, though the degree and pattern of variegation is very variable.

Key advice:Stolons are white shoots produced from the bulb. Most run horizontally, either underground or along the ground surface but beneath leaf litter. Flowering individuals often produce no stolons. The stolon characters in the key below are those of non-flowering individuals and refer to horizontal stolons only.
