''Laelia'', abbreviated L. in the horticultural trade,〔(【引用サイトリンク】publisher=Royal Horticultural Society )〕 is a small genus of 25 species from the orchid family (Orchidaceae). This is one of the most important and popular orchid genera, because of the beautiful flowers, their genetic properties and because they are fairly easy in culture. John Lindley did not specify his reasons for naming this orchid as he did; one possibility is that he named it after Laelia, one of the Vestal Virgins. ''Laelia'' species are found in the subtropical or temperate climate of Central America, but mostly in Mexico. ''Laelia speciosa'' is a high-elevation plant, preferring sunny, dry and cool conditions. The others grow in the rainforest with a warm, humid summer and a dry cool winter. The species ''L. albida'', ''L. anceps'' and ''L. autumnalis'' prefer higher and cooler altitudes. ''Laelia'' is one of the orchid genera known to use crassulacean acid metabolism photosynthesis, which reduces evapotranspiration during daylight because carbon dioxide is collected at night. Most are epiphytes, but a few are lithophytes, such as'' Laelia anceps''. They are closely related to ''Cattleya'', but have twice as many pollinia. Stems are usually short, however the stem of ''Laelia anceps'' can be more than 1 m long. The ovate pseudobulbs are clearly separate. These are about 6 – 30 cm long. One or two waxy, leathery leaves develop from each pseudobulb. This leaf can be up to 20 cm long. The inflorescence is a raceme, which can be 30 cm long, with up to eight flowers, growing from the top of the pseudobulb. These flowers can be pink to purple, with a beautifully colored purple lip becoming white close to the column . They bloom in spring or autumn. Albino varieties are rare and therefore prized. Due to high demand for such a rare mutations, many horticultural labs use modern tissue culture or mericloning techniques to increase their availability. Members of this genus tend to be fairly easy in culture, and some plants are surprisingly drought-tolerant. Culture is highly dependent upon the natural habitat of the species in question, although many do well as mounted (plaqued) specimens so that the roots receive plenty of air circulation and a sharp wet-and-dry cycle. The Brazilian ''Laelias'', after being classified for several years under ''Sophronitis'', have now been placed in the genus ''Cattleya''. Species formerly placed in the genus ''Schomburgkia'' have been moved either to the genus ''Laelia'' or ''Myrmecophila''. 〔http://www.aos.org/Default.aspx?id=171 AOS article "Farewell Schomburgkia"〕 ''Laelia'' species readily form hybrids within the genus, and with other genera, including ''Cattleya'', ''Brassavola'', and ''Rhyncholaelia''. ==Species== *''Laelia albida'' Bateman ex Lindl. * *''Amalia albida'' (Bateman ex Lindl.)
