Eulophia (Greek, handsome crest). Orchidaceae. Terrestrial orchids, requiring warmhouse conditions.

The genus '''''Eulophia''''' includes 210 species of [[orchid]]s, subfamily [[Vandoideae]], tribe [[Cymbidieae]], subtribe [[Cyrtopodiinae]].

Rather small plants with membranaceous Lvs. and conspicuous pseudobulbs: scape basal, several-fld.; sepals and petals spreading, similar, ascending; labellum 3-lobed; pollinia 2.—About 50-60 species, in the tropics of both hemispheres. The cult. of Calanthe will apply to this genus.
  
−
The genus was first described by [[John Lindley]] in 1821. The name "Eulophia" was derived from the Greek words "eu" (well) and "lophos" (plume), referring to the crested ridges of the [[labellum]] (lip) in most species.

These are usually [[terrestrial plant|terrestrial]] or ground orchids, although some are [[epiphyte]]s, and rarely, [[lithophyte]]s. They  are distributed in shady rainforests or in open scrub or woodland in the tropics and subtropics of [[Africa]], [[India]], [[Asia]], [[Queensland]] (Australia), and the [[Americas]], although most are found in Africa. Many can survive the dry season through their large bulbous ‘corms’.

Some species, such as ''Eulophia petersii'', have adapted to very arid environments and are among the few orchids to have truly evolved [[desert]] living species. In the frost-free, semi-arid areas of Southern California, many ''Eulophia'' species, such as ''E. macra'', ''E. petersii'', ''E. plantaginea'', and ''E. speciosa'', can be grown outdoors year-round in well-drained pots with cactus/succulent potting mix (although E. speciosa prefers being grown in pure white sand), as long as they are given ample light through the winter and a drier winter resting period. Warmer growers, such as ''E. pulchra'', ''E. keithii'', and possibly even the extremely rare and difficult ''E. cucullata'' (the foxglove orchid), can probably be grown outdoors in the warmer areas of Florida and Hawaii, also.

The [[deciduous]] or [[evergreen]] leaves are usually pleated, with longitudinal veins. They are green and sheathed at the base. But in some species, the leaves may be reduced or have become brown scales. Some are leafless [[myco-heterotrophs]].

The generally large, underground, fleshy [[rhizome]] indicates a [[sympodial]] growth habit, and this makes Eulophias fairly easy to divide and propagate, provided the grower is gentle.

The [[inflorescence]] arises from the base. It grows into a [[raceme]]. It is sometimes branched, as in the cases of ''E. macra'' and ''E. petersii''. The inflorescences on the species with non-brancing spikes can support as many as 50 flowers; but in species with branching inflorescences, up to 150 blooms can occur per spike. While most ''Eulophia'' flowers rarely exceed 2" in width, this is often made up for by the sheer abundance of interesting blooms they produce. The [[sepals]] and the [[petals]] are alike. The [[labellum|lip]] usually has three lobes. As for all orchids, there are two [[pollinia]] for each flower. Eulophias (in bloom) can reach a height of 1.6m (6ft.). In any case, the ease of cultivation and reliability of blooming that many Eulophia species and hybrids demonstrate in captivity, in addition to their unique growth habits, makes them generally excellent orchids for amateur orchid collectors and people who like to grow plants with interesting flowers.
