Bulbs | ovoid, 10–25 mm; stolon 1 in flowering plants, arising from halfway up stem, 1–3 from bulbs of 1-leaved, nonflowering plants. |
ovoid, 20–50 mm, producing bulbels (usually 1–3 per parent bulb) at ends of long, slender stolons. |
Leaves | 4–13 cm; blade green, irregularly mottled, elliptic-lanceolate to ovate-lanceolate or elliptic, ± flat, glaucous, margins entire. |
4–16 cm; blade mottled with irregular streaks of brown or white, ± lanceolate, margins entire to wavy. |
Scape | 3.9–12 cm. |
8–23 cm, branching just above leaves near ground level when flowers more than 1. |
Inflorescences | 1-flowered. |
1–4-flowered. |
Flowers | tepals 4–6, strongly reflexed at anthesis, pale pink to white, darker abaxially, lanceolate, 8–15 mm, auricles absent; stamens 2–6, 6–8 mm; filaments white, lanceolate; anthers yellow; pollen yellow; style white, 6–10 mm; stigma ± unlobed. |
flowering individuals generally uncommon in populations, most plants 1-leaved and vegetative; tepals white to cream with yellow base, broadly lanceolate to elliptic, 16–40 mm, inner with small auricles at base; stamens 10–15 mm; filaments white, linear, slender, less than 0.8 mm wide; anthers white to cream; style white, 10–13 mm; stigma unlobed or with recurved lobes 1–4 mm. |
Capsules | very rarely produced; when present, may be result of hybridization with Erythronium albidum. |
obovoid, 2–5 cm. |

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 multiscapideum is unusual among western species (and resembles some eastern species) in its tendency to reproduce vegetatively through the production of bulbels at the ends of stolons. It is similar in many respects to E. californicum and sometimes intergrades with it, resulting in occasional populations with the bulb characteristics of one species and the inflorescence branching pattern of the other.
