Appearance and leaves

Zephyranthes species are perennial herbaceous plants . These geophytes form egg to spherical onions with black to brown cover ("tunic") as persistence organs. The basal, upright or bent down leaves are simple, flat, linear, sessile, smooth and about 1 centimeter wide. The leaf bases overlap.

Inflorescences and flowers

Usually only one flower stands in a inflorescence with a single, röhrigem at its base husk together on a long, hollow inflorescence stem. The more or less upright, hermaphrodite, almost radially symmetrical , threefold flowers are trumpet-shaped to urn-shaped and have a diameter of 2 to 16 centimeters. The six almost identical bloom cladding sheets ( tepals ), which are only fused at their base, are mostly white. There is a circle with three short and one with three long stamens ; they are briefly fused with the bracts. Three carpels have become an under constant ovary grown, many ovules contains. The thin style ends in a cephalic or three-lobed to branched scar.

Fruits and seeds

Usually almost spherical, three-chambered, thin-walled capsule fruits are formed that contain many black seeds.

Systematics and distribution

The genus Zephyranthes was established in 1821 by William Herbert in An Appendix , p. 36. The generic name Zephyranthes is made up of the name of the Greek god of the west wind Zephyr and the Greek word ἄνθος ánthos for "blossom" or "flower". Synonyms for Zephyranthes Herb. nom. cons. are: Haylockia Herb. , Atamosco Adans. , Atamasco Raf. , Aidema Ravenna , Argyropsis M. Roem . , Arviela Salisb. , Cooperia Herb. , Sceptranthes Graham , Mesochloa Raf. , Plectronema Raf. , Pogonema Raf. , × Cooperanthes Percy-Lanc.

The genus Zephyranthes belongs to the subtribe Zephyranthinea from the tribe Hippeastreae in the subfamily Amaryllidoideae within the family of Amaryllidaceae . Sometimes the common name rain lilies is used for this genus; but this is also the common name of the closely related genera Habranthus Herb. and Cooperia Herb., so this name is used for all genera of the subtribe Zephyranthinea.

Zephyranthes species are widespread in the New World . Their distribution area extends from the south-eastern and south-central USA (about 16 species) over Mexico and Central America as well as the West Indies to South America . Some species are invasive plants in subtropical and tropical countries outside of the New World.

There are around 40 to 70 (depending on whether the Cooperia species are included or not) Zephyranthes species:

The genus Zephyranthes no longer includes species identified by Flagg et al. In 2010 the following were placed in the genus Habranthus :

use

A large number of varieties of a few species (especially Zephyranthes minuta ) are used as ornamental plants in parks and gardens in frost-free areas.
