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.
Perennial from elongate bulb of 1 fleshy scale, generally with small, bead-like segments of persistent rhizome
Leaves 2 (1 in non-flower plant), basal, 6–35 cm, lanceolate to ovate (solitary basal leaf wider), narrowed to petiole, glabrous; margin entire to wavy
Inflorescence: raceme; flowers 1–10; bracts 0
Flower showy, nodding; perianth segments 6, similar, free, ± lanceolate, ± strongly recurved; stamens 6; style 1, stigma entire to 3-lobed
Fruit ovoid to oblong
Seed ± ovoid, ± angular, brown
Chromosomes: n=12
Species in genus: ± 25 species: especially temp North America

Reference: [Applegate 1935 Madroño 3:58–113; Shevock et al. 1990 Madroño 37:261–273]
Attractive in woodland gardens. Pressed specimens fade, so leaf and flower markings should be recorded fresh.

See the CNPS Inventory for information about endangerment and rarity.| YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps). |
