Шаблон:Short description Шаблон:Automatic taxobox

Echeveria is a large genus of flowering plants in the family Crassulaceae, native to semi-desert areas of Central America, Mexico and northwestern South America.

Description

Plants may be evergreen or deciduous. Flowers on short stalks (cymes) arise from compact rosettes of succulent fleshy, often brightly coloured leaves.[1] Species are polycarpic, meaning that they may flower and set seed many times over the course of their lifetimes. Often numerous offsets are produced, and are commonly known as "hen and chicks", which can also refer to other genera, such as Sempervivum, that are significantly different from Echeveria. Many species of Echeveria serve important environmental roles, such as those of host plants for butterflies. For example, the butterfly Callophrys xami uses several species of Echeveria, such as Echevelia gibbiflora, for suitable host plants. Even more, these plants are integral to the oviposition process of C. xami and some other butterfly species as well.[2][3]

Etymology

Echeveria is named for Atanasio Echeverría y Godoy, a botanical illustrator who contributed to Flora Mexicana.[4]

Taxonomy

The genus was erected by A. P. de Candolle in 1828, and is named after the 18th century Mexican botanical artist Atanasio Echeverría y Godoy. Шаблон:As of, the genus consists of about 150 species, including genera such as Oliveranthus and Urbinia that have formerly been split off from Echeveria. Molecular phylogenetic studies have repeatedly shown the genus not to be monophyletic: species of Echeveria cluster with species of Cremnophila, Graptopetalum, Pachyphytum, and Thompsonella as well as species of Sedum sect. Pachysedum. The former Urbinia species do appear to form a monophyletic group within this grouping.[5][6] Although it is clear that Echeveria is not monophyletic, its limits are not clear, and further analyses are needed to determine whether and how the genus should be split, or if it should be included in an expanded concept of Sedum.[6]

Species

The International Crassulaceae Network accepts the following species:[7]

Cultivation

Echeveria secunda

Many Echeveria species are popular as ornamental garden plants. They are drought-resistant, although they do better with regular deep watering and fertilizing. Most will tolerate shade and some frost, although hybrids tend to be less tolerant. Most lose their lower leaves in winter; as a result, after a few years, the plants lose their compact appearance and need to be re-rooted or propagated. In addition, if not removed, the shed leaves may decay, harboring fungus that can then infect the plant.

Propagation

They can be propagated easily by separating offsets, but also by leaf cuttings, and by seed if they are not hybrids.
