Higher Taxonomy
Family: LiliaceaeView DescriptionDichotomous Key
Common Name: LILY FAMILY
Habit: Perennial herb from membranous bulb or scaly rhizome. Stem: underground or erect, branched or not. Leaf: basal or cauline, alternate, subopposite, or whorled. 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. Fruit: capsule or berry. Seed: 3--many, flat or angled, brown to black.
Genera In Family: 16 genera, 635 species: northern temperate. Note: Users strongly encouraged to protect plants by working around need to see underground parts in using keys, e.g., by trying both leads in couplets solely dependent on such characters. Muscari botryoides (L.) Mill. an historical waif in California.

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.

Species: Lilium washingtonianumView Description 

Habit: Plant < 2.6 m, often glaucous; bulb oblique-elongate to +- erect-ovoid, scales unsegmented, 2-segmented, or indistinctly 2(3)-segmented, longest 3.3--12 cm. Leaf: in 1--9(14) whorls, spreading to ascending, +- clasping stem or not, 3--13 cm, generally oblanceolate; margin wavy or not. Inflorescence: flowers 1--33, nodding to ascending. Flower: generally +- bilateral, +- funnel-shaped, strongly fragrant; perianth parts generally 6.2--11.3 cm (inner wider, strongly oblanceolate), recurved in distal 25--33%, white, turning deep pink or not, magenta spots minute; stamens +- exceeding perianth, filaments +- parallel, anthers 8--15 mm, off-white or cream, pollen yellow or cream; pistil 7.5--10.4 cm.
