The calochortus ( Calochortus ) are a genus of flowering plants in the family of the lily family (Liliaceae). The 70 to 74 species are distributed from western North America through Mexico to Guatemala .

Origin of common names and symbols

The indigenous peoples of Utah called Calochortus nuttallii “sago” (the Shoshone “sago” is the word for edible onion) and told the Mormons that they were edible. The cooked onion was used as food by the Utah settlers around 1848 and thus saved them from starvation. Therefore, in 1911 Calochortus nuttallii was declared the state flower of Utah , there called Sego Lily.

Calochortus species are perennial herbaceous plants . These geophytes form onions as persistent organs. At most there are very small leaves on the upright stem . The mainly basal and alternate leaves are sessile, linear, simple, flat, have parallel veins and have entire margins.

The flowers are in terminal, simple or branched, racemose inflorescences with bracts . The long-stalked, hermaphrodite flowers are radial symmetry and threefold. There are two circles with three free bracts each. In some species the bracts of both circles are identical, in many species they are clearly different in shape and size. Nectar glands are located at the base of the inner bracts. Often the bracts are spotted. When they differ, the outer bracts are often narrower, smooth, sometimes green, or the same color as the inner ones. The inner bracts are often nailed, fringed, hairy, yellow, pink to red and often they are patterned. There are two circles with three fertile stamens each; they are always free from each other, but they can grow together with the base of the bracts. Three carpels have become a top permanent ovary grown. Each of the three ovary chambers contains 30 to 50 ovules . Pen can often not recognize when they are present, they are much shorter than the ovary. The scar is three-lobed.

The upright, bursting capsule fruits are three-leaved. The seeds are mostly flattened.

Systematics and distribution

The genus Calochortus was created by Frederick Traugott Pursh in 1814 in Flora Americae Septentrionalis; or, ... , Volume 1, p. 240. Type species is Calochortus elegans Pursh . The botanical genus name Calochortus is derived from the Greek words kalos for beautiful and chortos for grass. Synonyms for Calochortus Pursh are: Cyclobothra D.Don , Mariposa (Alph.Wood) Hoover .

The genus Calochortus belongs to the subfamily Calochortoideae Dumort. within the family Liliaceae . Some authors place the genus Calochortus in a family Calochortaceae Dumort. with five genera.

Calochortus species thrive in temperate climates from North to Central America . The Calochortus species are found from British Columbia in western North America (56 species) via Mexico to Guatemala .

The genus Calochortus is divided into three sections, each with four subsections:

  • Section Calochortus :
    • Pulchellii subsection
    • Subsection elegant
    • Subsection Nudi
    • Subsection Nitidi
  • Section Cyclobothra :
    • Barbati subsection
    • Ghiesbreghtiani subsection
    • Purpurei subsection
    • Weediani subsection
  • Mariposa Section :
    • Gunnisoniani subsection
    • Macrocarpi subsection
    • Subsection Nuttalliani
    • Sub-section Venusti

There are 70 to 74 species in the genus Mormon tulips ( Calochortus ):

use

The onions can be eaten raw or cooked.

Some of the species and their varieties are rarely used as ornamental plants due to the very attractive flowers . They are considered delicate plants for lovers.
