Discussion | Of conservation concern. Erythronium propullans is known only from Goodhue and Rice counties. It often forms extensive colonies in which flowering plants are sometimes more abundant than nonflowering, 1-leaved ones, and sometimes the reverse. It grows mixed with E. albidum (J. A. Banks 1980), and putative hybrids between them have been reported (T. Morley 1988). Flowers frequently have fewer than six tepals and stamens (C. O. Rosendahl 1919), and may occasionally have only two carpels. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Erythronium quinaultense is a tetraploid species apparently derived from hybridization between E. montanum and E. revolutum. It is known only from the southwestern Olympic Peninsula. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
