Dale W. McNeal, except as specified

Perennial to trees, from membranous bulb, fibrous corm, scaly rhizome, or erect caudex
Stem generally underground
Leaves generally basal, often withering early, alternate, generally ± linear
Inflorescence various, generally bracted
Flower generally bisexual, generally radial; perianth often showy, segments generally 6 in two petal-like whorls (outer sometimes sepal-like), free or fused at base; stamens 6 (or 3 + generally 3 ± petal-like staminodes), filaments sometimes attached to perianth or fused into a tube or crown; ovary superior or inferior, chambers 3, placentas generally axile, style generally 1, stigmas generally 3
Fruit: generally capsule, loculicidal or septicidal (berry or nut)
Genera in family: ± 300 genera, 4600 species: especially ± dry temp and subtropical; many cultivated for ornamental or food; some TOXIC. Here includes genera sometimes treated in Agavaceae, Amaryllidaceae, and other families.



Bryan D. Ness

Perennial; bulb with 1–several large fleshy scales, 0–many small scales
Stem erect, simple (0 in non-flower plants)
Leaves alternate (or whorled below), sessile, linear to ± ovate (1 "bulb-leaf" in non-flower plants)
Inflorescence: raceme; bracts leaf-like
Flower generally nodding, bell- or cup-shaped; perianth segments 6, of 2 similar whorls; nectaries 6, on perianth parts; stamens 6, included, inserted at perianth base, anthers attached ± near middle; ovary ± sessile, style 1, entire or 3-branched
Fruit: capsule, loculicidal, thin walled, ± rounded, 6-angled, or winged, chambers 3
Seeds many, 2 rows per chamber, flat, brownish
Species in genus: ± 100 species: n temp
Etymology: (Latin: dicebox, from fruit shape)
Reference: [Turrill & Sealy 1980 Hooker's Icones Plantarum 34:1–275]
Bulbs of some eaten by Indians of North America
Horticultural information: DRN: for pots or rock gardens; DRY when dormant. Most are very DFCLT.


F. affinis (Schult. & Schult. f.) Sealy


Bulb; large scales 2–5; small scales 2–20
Stem 1–12 dm
Leaves in 1–4 whorls of 2–8 below, alternate above, 4–16 cm, linear-lanceolate to ovate
Flower nodding; perianth parts 1–4 cm, oblong to ovate, brownish purple mottled yellow to pale yellowish green mottled purple; nectary 1/2–2/3 perianth length, lanceolate, yellow with purple dots; style divided 1/2
Fruit widely winged
Chromosomes: 2n=24,36,48
Ecology: Common. Oak or pine scrub, grasslands

Distribution outside California: to British Columbia, Idaho
Synonyms: F. lanceolata Pursh (illegitimate name); F. phaeanthera Purdy
Highly variable; needs further study; hybridizes with F. recurva.

Information on Distribution was contributed by Claire Golec (21 Apr 2004):
In reviewing a Fritillaria roderickii site along Highway 1 (around mile marker 10.84) a population (~20 plts.) of what used to be referred to as Fritillaria lanceolata was noted between the highway and ocean (immediate coastal bluffs)


var. tristulis (A.L. Grant) Ness ined.

Bulb with 60–100+ small scales
Flower: perianth parts scarcely mottled
Ecology: Very uncommon. Coastal grassland
Elevation: < 100 m.
Bioregional distribution: n Central Coast (w Marin Co.).
