Inflorescence: raceme, panicle, +- umbel-like or not. Flower: perianth parts 6 in 2 generally petal-like whorls, often showy; stamens 3 or 6, filaments free or +- fused to perianth, anthers attached at base or near middle; ovary superior or +- so, style 1, entire or 3-lobed.

Genus: LiliumView DescriptionDichotomous Key

Common Name: LILY
Habit: Plant from bulb-like, scaly rhizomes (called bulbs here for brevity), generally not clonal, +- glabrous; bulb scale segments 2--many, if segmented. Stem: erect. Leaf: > 12, +- whorled (often some alternate), sessile, spreading with drooping tips to ascending, generally +- elliptic; veins generally 3; stipule 0. Inflorescence: flowers axillary, 1--40+; bracts generally 2 per flower. Flower: generally radial, generally bell- or funnel-shaped; perianth parts 6 in 2 petal-like whorls, +- lanceolate, base narrowed, generally red-purple-spotted adaxially; stamens 6, generally exceeding to much exceeding perianth, anthers attached at middle (measures are after dehiscence); style 1, stigma 3-lobed. Fruit: capsule, erect, generally +- smooth, loculicidal. Seed: many, flat, in 6 stacks. Chromosomes: n=12.
Etymology: (Greek: lily) Note: Variable, hybridization common. Many species declining from habitat destruction, collecting; few thrive in gardens. Generally flowers May--Aug.

All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
