Description

Family Liliaceae

Herbs perennial , with a rhizome, bulb, or corm, rarely shrubby or treelike. Leaves basal and/or cauline, alternate, opposite, or whorled , parallel or rarely reticulate veined. Inflorescence a raceme , panicle, spike, umbel, reduced panicle, or other, or flowers solitary. Flowers bisexual , rarely unisexual , actinomorphic , rarely zygomorphic; bracts present or absent; bracteoles present or absent. Perianth usually corollalike, 6-merous, rarely 4- or 8-merous, in 2 whorls; segments free (tepals) or united . Stamens 6, rarely 3, 4, or 8, inserted opposite perianth segments; filaments free or adnate to perianth, rarely connate into a corona ; anthers usually 2-loculed, basifixed or dorsifixed and versatile, introrse , latrorse , or extrorse , dehiscing usually by vertical slits. Carpels usually connate for most or all of their length , rarely only at base ; ovary superior, rarely semi-inferior, 3-loculed, rarely 2- or 4-loculed, with axile placentae, or rarely 1-loculed with a parietal placenta; ovules usually anatropous . Nectaries septal, perigonal, or absent. Fruit a capsule or berry. Seeds with abundant endosperm and small embryo.

About 250 genera and 3500 species: worldwide, especially in temperate and subtropical regions; 57 genera (three endemic, two introduced ) and 726 species (379 endemic, 11 introduced) in China.[1]

Genus Calochortus

Herbs, perennial , sometimes from bulbs; bulb coat membranous or fibrous-reticulate. Stems scapelike or leafy, simple or branched, glabrous , often glaucous; bulblets sometimes borne in leaf axils . Leaves sessile; basal persistent or withering by flowering, solitary, blade base sometimes attenuate and petiolelike; cauline 0-several, sometimes proximalmost appearing as basal, reduced. Inflorescences monochasiate or ± umbellate , 1-many-flowered, bracteate . Flowers: perianth globose to broadly campanulate ; sepals 3, distinct , ovate to lanceolate, usually petaloid and glabrous; petals 3, distinct, usually longer and broader than sepals, sometimes clawed, usually hairy adaxially, bearing adaxial gland near base, often spotted to ± patterned; filaments widened at base; anthers usually basifixed or pseudobasifixed, linear to oblong ; ovary superior; style absent; stigmas 3. Fruits capsular , 3-locular, 3-angled or -winged, linear, oblong, or globular , dehiscence septicidal . Seeds many, in 2 rows per locule, irregular or flat, coat usually hexagonally reticulate .

Species ca. 70: w North America, Central America.

Many species of Calochortus are in cultivation. Bulbs of some species were eaten by Native Americans. Petal shape, gland shape, and pubescence are exceedingly variable in many taxa but often are important in identifying species.

As part of a phylogenetic analysis of relationships within the Liliales, T. B . Patterson (1998) studied variation in noncoding cpDNA sequences throughout Calochortus. He resolved seven main clades that are geographically and ecologically strongly cohesive, including the mariposas of dry grasslands and semideserts, the star-tulips of wet meadows, the cat's ears of montane woodlands, and the fairy lanterns of closed forests . Patterson suggested that this pattern of relationships is the result of highly localized speciation within the genus.[2]
