Glacier lily, more...
[Erythronium grandiflorum var. minus , more]
Bulbs slender, 30-50 mm. Leaves 5-20 cm; blade green, lanceolate, ± glaucous, base gradually narrowed to petiole, margins ± wavy. Scape 5-30 cm. Inflorescences usually 1-flowered, sometimes up to 5-flowered. Flowers: tepals recurved, bright yellow with (in live specimens) narrow paler zone at base, or white to creamy white with yellow base, narrowly ovate, 20-35 mm, length at least 4 times width, inner usually auriculate at base; stamens 11-18 mm; filaments white, ± slender, linear, less than 0.8 mm wide; anthers cream, yellow, red, or purplish red; pollen yellow or red; style white, 10-15 mm; stigma unlobed or with slender, recurved lobes (1-)2-4 mm. Capsules oblong to narrowly obovoid, 2-5 cm. 2n = 24. This beautiful species is often very abundant in mountain meadows of western North America, especially in the Rocky Mountains, where it may form spectacular displays. It is often difficult to grow in cultivation outside its preferred habitats. Bulbs of this species were a staple food for native North American peoples of several tribes, and were eaten in large quantities and also traded. Within the typical subspecies, both anthers and pollen vary considerably in color; plants with pale anthers have been called var. pallidum, and forms with yellow anthers, var. chrysandrum. Plants possessing very short stigma lobes and lacking auricles on the tepals have been recognized as var. nudipetalum, but they do not appear sufficiently distinct to warrant taxonomic recognition and may simply represent depauperate forms.
