Erythronium propullans
Erythronium albidum
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.

Erythronium albidum often forms extensive colonies in which nonflowering, 1-leaved plants far outnumber flowering, 2-leaved ones. It is very widespread in eastern North America, more common in the central states than E. americanum and often occurs in slightly drier sites.
