Oeceoclades decaryana is a terrestrial orchid species of the genus Oeceoclades that is native throughout southern and southeastern Africa. It can be found growing in Kenya, Mozambique, Zimbabwe, Madagascar, and KwaZulu-Natal in South Africa. It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1935 as a species in the genus Eulophia. He later transferred this species to the genus Lissochilus in 1941, followed by another transfer to the genus Eulophidium in 1957 by the English botanist V.S. Summerhayes in 1957. When Leslie Andrew Garay and Peter Taylor revised the genus Oeceoclades in 1976, they transferred this species to the expanded Oeceoclades.
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.
Oeceoclades alismatophylla is a species of orchid in the genus Oeceoclades that is native to Comoros and northeastern Madagascar. It was first described by the German botanist Heinrich Gustav Reichenbach in 1885 as Eulophia alismatophylla and later transferred to the genus Eulophidium in 1957 by V.S. Summerhayes. When Leslie Andrew Garay and Peter Taylor revised the genus Oeceoclades in 1976, they transferred this species to the expanded Oeceoclades as O. alismatophylla. Garay and Taylor noted that this species is broadly similar in vegetative morphology to O. analamerensis, O. lonchophylla, and O. petiolata but could be distinguished from them in floral morphology, with O. alismatophylla having lateral labellum lobes that are larger than the middle one.
Oeceoclades analamerensis is a terrestrial orchid species in the genus Oeceoclades that is endemic to northern Madagascar. It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1939 as Lissochilus analamerensis. The English botanist V.S. Summerhayes later transferred this species to the genus Eulophidium in 1957. When Leslie Andrew Garay and Peter Taylor revised the genus Oeceoclades in 1976, they transferred this species to the expanded Oeceoclades.
Oeceoclades analavelensis is a terrestrial orchid species in the genus Oeceoclades that is endemic to southwestern Madagascar. It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1939 as Lissochilus analavelensis. The English botanist V.S. Summerhayes later transferred this species to the genus Eulophidium in 1957. When Leslie Andrew Garay and Peter Taylor revised the genus Oeceoclades in 1976, they transferred this species to the expanded Oeceoclades.
Oeceoclades atrovirens is a terrestrial orchid species in the genus Oeceoclades. It was first described by the English botanist John Lindley in 1833 as Eulophia atrovirens and later transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Lindley based his initial description of the species on a color drawing that Nathaniel Wallich completed in 1828 for the East India Company. No specimens of this plant are known, so this species is only represented by the single illustration. Wallich indicated on the drawing that the species was seen in India, but he did not provide a specific location. The World Checklist of Selected Plant Families lists the distribution of O. atrovirens, with some uncertainty, as possibly being in India or Mauritius.
Oeceoclades cordylinophylla is a terrestrial orchid species in the genus Oeceoclades that is native to Comoros and northern Madagascar. It was first described by the German botanist Heinrich Gustav Reichenbach in 1885 as Eulophia cordylinophylla. It was first transferred to the genus Lissochilus by Joseph Marie Henry Alfred Perrier de la Bâthie in 1941, then to the genus Eulophidium by V.S. Summerhayes in 1957, and later to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. The type specimen was collected from the Comoro Islands by Léon Humblot, but the actual specimen is missing. Garay and Taylor indicated that an herbarium sheet of Humblot's with an unpublished name by Reichenbach appears to align well with the original description. The margins of the column wings of O. cordylinophylla are ciliolate-hirsute, fringed with stiff, minute hairs.
Oeceoclades hebdingiana is a terrestrial orchid species in the genus Oeceoclades that is endemic to western Madagascar. It was first described by the French botanist André Guillaumin in 1964 as Lissochilus hebdingianus. It was then transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Garay and Taylor noted that this species is related to O. calcarata, but differs in the shape of the labellum. Oeceoclades calcarata also has a forward-projecting spur, while O. hebdingiana does not.
Oeceoclades lanceata is a terrestrial orchid species in the genus Oeceoclades that is endemic to central Madagascar. The flowers are rose-colored. It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1935 as Eulophia lanceata. Perrier then later reduced the species to a synonym of Eulophia pandurata. The species was resurrected and transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor, who argued that O. lanceata and O. pandurata are distinct with regard to their floral structure and shape of the labellum. Garay and Taylor noted that O. lanceata is similar in vegetative morphology to O. seychellarum.
Oeceoclades latifolia is a terrestrial orchid species in the genus Oeceoclades that is endemic to São Tomé Island. It was first described by the British botanist Robert Allen Rolfe in 1891 as Eulophia latifolia, then moved to the genus Eulophidium by V.S. Summerhayes in 1957 and again moved to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Garay and Taylor noted that O. latifolia is similar in vegetative morphology to O. atrovirens but the floral structure is more similar to O. ugandae. The lateral veins on the labellum are fringed with small hairs, a characteristic that is shared with O. pandurata, O. seychellarum, and O. lanceata.
Oeceoclades lonchophylla is a terrestrial orchid species in the genus Oeceoclades that is native to Tanzania, Mozambique, KwaZulu-Natal in South Africa, and Comoros. It was first described by the German botanist Heinrich Gustav Reichenbach in 1885 as Eulophia lonchophylla, then moved to the genus Eulophidium by Rudolf Schlechter in 1925 and to the genus Lissochilus by Joseph Marie Henry Alfred Perrier de la Bâthie in 1941. It was last transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Garay and Taylor also reduced the species Eulophia tainioides to a synonym of O. lonchophylla for lack of distinguishing characteristics that could separate the two species.
Oeceoclades lubbersiana is a terrestrial orchid species in the genus Oeceoclades that is native to the Democratic Republic of the Congo and Uganda. It was first described by the Belgian botanists Émile Auguste Joseph De Wildeman and Émile Laurent in 1899 as Eulophia lubbersiana, then moved to the genus Eulophidium by V.S. Summerhayes in 1957 and again transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Garay and Taylor noted that this species is similar to O. atrovirens in vegetative morphology, but is better allied to O. latifolia and O. pandurata because all three possess a labellum that is wider than it is long. Oeceoclades lubbersiana was named in honor of Louis Lubbers, who was a botanist working at the Botanical Garden of Brussels.
Oeceoclades seychellarum is a terrestrial orchid species in the genus Oeceoclades that was endemic to the island of Mahé in the Seychelles but is now considered to be extinct. Its sepals and petals are yellowish-white, while the labellum is white with some streaks. This species is only represented by the type specimen, collected in May 1902 from the Cascade Estate on the island of Mahé at an elevation of 900 feet (270 m) in what was then a mountain forest. The location from which the type specimen was collected is now degraded by human activity and invasive plants. Oeceoclades seychellarum was listed as being cultivated at the Royal Botanic Gardens, Kew in 1905, but not after that date.
Oeceoclades pandurata is a terrestrial and epiphytic orchid species in the genus Oeceoclades that is native to eastern Zimbabwe and Madagascar. It was first described by the British botanist Robert Allen Rolfe in 1891 as Eulophia pandurata, then moved to the genus Lissochilus by Joseph Marie Henry Alfred Perrier de la Bâthie in 1941, and again moved to the genus Eulophidium by V.S. Summerhayes in 1957. It was finally transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Garay and Taylor noted that this species possesses lateral veins on the labellum that fringed with small hairs. Oeceoclades pandurata is distinguishable from other species in the genus by the lateral lobes of the labellum, which are free and truncate. The type specimen was collected on trees near Fort Dauphin on Madagascar, now known as the city of Tôlanaro. The specific epithet pandurata refers to the fiddle-shaped labellum.
Oeceoclades perrieri is a terrestrial orchid species in the genus Oeceoclades that is native to Mozambique and northwestern Madagascar. It was first described by the German botanist Rudolf Schlechter in 1913 as Eulophia ambongensis. Schlechter had also described a separate species, Eulophidium ambongense in the same 1913 work. When Leslie Andrew Garay and Peter Taylor resurrected and revised the genus Oeceoclades in 1976, these two taxa caused a naming conflict, so they chose to use Eulophidium ambongense as the basionym for O. ambongensis and reduced Eulophia ambongensis to a synonym of O. perrieri, which was based on the basionym Eulophidium perrieri that Schlechter had also described later in 1925. Both Eulophidium perrieri and Eulophia ambongensis were conspecific, belonging to the same species, so Garay and Taylor were free to use the later name as the base for their new combination when transferring taxa to Oeceoclades. Garay and Taylor noted that this species is related to O. quadriloba, O. sclerophylla, and O. analavelensis but can be distinguished from them by its characteristic long strap-like leaves that taper to a point.
Oeceoclades petiolata is a terrestrial orchid species in the genus Oeceoclades that is endemic to northern and western Madagascar. It was first described by the German botanist Rudolf Schlechter in 1913 as Eulophia petiolata. Schlechter later moved this species to the genus Eulophidium in 1925. It was again moved to the genus Lissochilus by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1941 and last transferred the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Garay and Taylor noted that this species is almost identical to O. alismatophylla in vegetative morphology, but the two differ in the shape of the labellum on the flower. The labellum is fiddle-shaped and has three thickened veins in front of the calli.
Oeceoclades quadriloba is a terrestrial orchid species in the genus Oeceoclades that is native to Eswatini, southern Zimbabwe, and western Madagascar. It was first described by the German botanist Rudolf Schlechter in 1913 as Eulophia quadriloba. Schlechter later moved this species to the genus Eulophidium in 1925. It was again moved to the genus Lissochilus by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1941 and last transferred the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Garay and Taylor noted that structure of the labellum is unique in the genus and resembles that of an Asian genus of orchids, Grosourdya. The spur is longer than the midlobe of the labellum.
Oeceoclades sclerophylla is a terrestrial orchid species in the genus Oeceoclades that is native to Comoros and southeastern Madagascar. It was first described by the German botanist Heinrich Gustav Reichenbach in 1885 as Eulophia sclerophylla. It was later transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor. Oeceoclades sclerophylla has long, linear leaves, a feature that is shared with O. analavelensis and O. quadriloba, but it differs from these species in the proportions of the size of labellum lobes.
Oeceoclades spathulifera is a terrestrial orchid species in the genus Oeceoclades that is endemic to northern and western Madagascar. It was first described by the French botanist Joseph Marie Henry Alfred Perrier de la Bâthie in 1935 as Eulophia spathulifera. Perrier later transferred the species to the genus Lissochilus in 1941 and it was again moved to the genus Eulophidium by V.S. Summerhayes in 1957. It was last transferred to the genus Oeceoclades in 1976 by Leslie Andrew Garay and Peter Taylor when they resurrected and revised that genus. Oeceoclades spathulifera is related to O. calcarata and O. hebdingiana but it can be distinguished from those species by its long, spathulate (spoon-shaped) sepals and petals and the globose spur.
Oeceoclades ugandae is a terrestrial orchid species in the genus Oeceoclades that is native to parts of tropical Africa, including west tropical Africa, west-central tropical Africa, northeast tropical Africa (Ethiopia), and east tropical Africa. It was first described by the British botanist Robert Allen Rolfe in 1913 as Eulophia ugandae and later transferred to the genus Oeceoclades in 1976 when Leslie Andrew Garay and Peter Taylor resurrected and revised that genus. The English botanist V.S. Summerhayes treated this species as a synonym of O. latifolia, but Garay and Taylor noted that while the two species share a superficial resemblance in the appearance of the labellum, they are distinct in vegetative morphology. The labellum of O. ugandae also has two swellings or protuberances between the lateral and midlobes, a feature that O. latifolia lacks.
