Genera

The Calochortoideae are a subfamily of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the Liliaceae (lily) family.

Approximately the same group of species has been recognized as a separate family, Calochortaceae, in a few systems of plant taxonomy, including the Dahlgren system.[1] They are found predominantly in the temperate regions of the Northern Hemisphere, particularly East Asia and North America.

Description

Flowers large with no or a very short style. Perianth differentiated into calyx and corolla, tepals pubescent. The embryo-sac is of the Polygonum-type.[2][3] Fruit forms a septicidal capsule.[4] Leaves have parallel venation. Chromosome number is between 6-13, and are 1.5 to 6.5µmin length.

Taxonomy

The two genera comprise about 90 species.
