EulophidiumPfitzer

Oeceoclades, collectively known as the monk orchids, is a genus of flowering plants from the orchid family, Orchidaceae. It is related to Eulophia and like that genus is mostly terrestrial in habit. A few species extend into very arid environments, unusual for an orchid.

Contents

The genus contains about 40 known species, most of which are narrow endemics to parts of Madagascar with some widespread across much of sub-Saharan Africa and the islands of the Indian Ocean. One species, O. maculata , has become naturalized in Mexico, South America, Central America, the West Indies and Florida. [2] [3] [4] [5] In Florida and several other places, O. maculata is considered an invasive weed. [6] [7]

The only consistent morphological character that does not show intermediate forms in either genus and can thus separate Oeceoclades from Eulophia is the presence of two fleshy ridges on the basal part of the labellum (the hypochile). The genus was resurrected by Leslie Andrew Garay and Peter Taylor in 1976 and since then has been affirmed as a monophyletic genus in molecular phylogenetic studies. [8]

<i>Phragmipedium</i>

Phragmipedium is a genus of the Orchid family (Orchidaceae) and the only genus comprised in the tribe Phragmipedieae and subtribe Phragmipediinae. The name of the genus is derived from the Greek phragma, which means "division", and pedium, which means "slipper". It is abbreviated 'Phrag' in trade journals.

<i>Brassia</i>

Brassia is a genus of orchids classified in the subtribe Oncidiinae. It is native to Mexico, Central America, the West Indies, and northern South America, with one species extending into Florida.

<i>Coelogyne</i>

Coelogyne is a genus of over 200 sympodial epiphytes from the family Orchidaceae, distributed across India, China, Indonesia and the Fiji islands, with the main centers in Borneo, Sumatra and the Himalayas. They can be found from tropical lowland forests to montane rainforests. A few species grow as terrestrials or even as lithophytes in open, humid habitats. The genera BolborchisLindl., HologynePfitzer and PtychogynePfitzer are generally included here. The genus is abbreviated Coel. in trade journals.

Laeliinae Subtribe of orchids

Laeliinae is a Neotropical subtribe including 40 orchid genera, such as Brassavola, Laelia and Cattleya. The genus Epidendrum is the largest within this subtribe, containing about 1500 species. This is followed by the genus Encyclia, with over 120 species.

<i>Polystachya</i> Genus of orchids

Polystachya, abbreviated Pol in horticultural trade, and commonly known as yellowspike orchid, is a flowering plant genus in the orchid family (Orchidaceae). This rather distinctive genus was described by William Jackson Hooker in 1824 and is the type genus of the subtribe Polystachyinae. It contains about 100 species widespread across many of the tropical areas of the world.

<i>Orthochilus</i> Genus of orchids

Orthochilus is a genus of orchids that consists of at least 34 species, most of which are native to Africa and Madagascar with a few species in tropical and subtropical America. The genus was first formally described in 1850 by the French botanist Achille Richard, who cited an earlier suggestion by the German botanist Christian Ferdinand Friedrich Hochstetter. Richard recognized a single species, Orthochilus abyssinicus, and noted that the genus shared many features with the closely related genus Eulophia, but differed from it in the form of the pollen masses and caudicule, a stalk to which the pollen masses are attached. The genus Orthochilus has often been viewed as a synonym of the larger genus Eulophia by many botanists, but a recent molecular phylogeny published in 2014 revealed that Eulophia, as traditionally circumscribed, was paraphyletic unless Orthochilus was recognized as a separate genus.

<i>Jumellea</i> Genus of orchids

Jumellea is an orchid genus with around 40 species native to Madagascar, the Comoros, the Mascarenes, and eastern Africa. In horticulture, it is often abbreviated Jum. It is named after H. L. Jumelle, a French botanist.

<i>Trichoglottis</i> Genus of orchid

Trichoglottis, commonly known as cherub orchids or 毛舌兰属 , is a genus of flowering plants in the family Orchidaceae. Orchids in this genus are epiphytic plants with thick roots, relatively thick, fibrous stems and many large, thick, leathery leaves arranged in two ranks. The flowers are usually small and yellowish with light brown or purple markings. The flowers have broad sepals, narrower petals and a labellum which has three lobes and is often hairy. There are about 85 species distributed from tropical and subtropical Asia to the north-western Pacific. Most species grow in rainforest.

Oeceoclades beravensis is a terrestrial orchid species in the genus Oeceoclades that is endemic to the southern and western Madagascar where it grows in the sandy soils of western dry forests and wooded grasslands. This species has cane-like stems and forms dense clumps in the understorey, a feature that makes it unique among the Eulophiinae species found in Madagascar. Like other orchid species in Eulophia and Oeceoclades that are adapted to arid climates, O. beravensis has narrow and coriaceous leaves with minute serrations.
