Bulbous herbs with simple leafy stems, and rather large nodding solitary or racemed 
leafy-bracted flowers. Perianth mostly campauulate, deciduous, of 6 separate and nearly 
equal oblong or ovate segments, each with a nectar-pit or spot at the base. Stamens 6, hy- 
pogynous; filaments filiform or somewhat flattened; anthers linear or oblong. Ovary 
nearly or quite sessile, 3-celled; oyules numerous in each cavity; style slender or filiform, 
3-lobed or 3-cleft, the lobes stigmatic along the inner side. Capsule obovoid or globose, 6-

8. ERYTHRONIUM L.,. Sp. Pl. 305.1753. 
Low herbs, from decp membranous-coated corms, sometimes propagated by offshoots, 
the stem simple, bearing a pair of broad or narrow unequal leaves, usually below the middle, 
the leaves thus appearing basal. Flowers large, nodding, bractless, solitary, or several in

longer petioled than those of the stem. Perianth-segments separate, lanceolate, oblong or 
oblanceolate, deciduous, with nectariferous groove, and sometimes 2 short processes at the
