Mozambique ( or ), officially the Republic of Mozambique (Portuguese: "Moçambique" or "República de Moçambique ", ] ) is a country in Southeast Africa bordered by the Indian Ocean to the east, Tanzania to the north, Malawi and Zambia to the northwest, Zimbabwe to the west, and Swaziland and South Africa to the southwest.
 It is separated from Madagascar by the Mozambique Channel to the east.
 The capital and largest city is Maputo (known as "Lourenço Marques" before independence).
Oeceoclades saundersiana is a terrestrial orchid species in the genus "Oeceoclades" that is native to a large area in tropical Africa.
 It can be found in west tropical Africa (Benin, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, and Sierra Leone), west-central tropical Africa (Central African Republic, Cameroon, Equatorial Guinea, Gabon, the Gulf of Guinea islands, Rwanda, and Democratic Republic of the Congo), northeast tropical Africa (Ethiopia), east tropical Africa (Kenya, Tanzania, and Uganda), and south tropical Africa (Angola and Zambia).
 It was first described by the German botanist Heinrich Gustav Reichenbach in 1866 as "Eulophia saundersiana".
 It was later transferred to the genus "Oeceoclades" in 1976 by Leslie Andrew Garay and Peter Taylor.
 Garay and Taylor noted that "O. saundersiana" has a labellum with four lobes of equal size and the pseudobulb is long and cylindrical with two leaves.
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 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 (an abrupt termination).
 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 ugandae is a terrestrial orchid species in the genus "Oeceoclades" that is native to parts of tropical Africa, including west tropical Africa (Ghana and Ivory Coast), west-central tropical Africa (Gulf of Guinea islands and the Democratic Republic of the Congo), northeast tropical Africa (Ethiopia), and east tropical Africa (Kenya and Uganda).
 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.
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 maculata, sometimes known as the monk orchid or African spotted orchid, is a terrestrial orchid species in the genus "Oeceoclades" that is native to tropical Africa and now naturalized in South and Central America, the Caribbean, and Florida in North America.
 It was first described by the English botanist John Lindley as "Angraecum maculatum" in 1821 based on a specimen collected from South America.
 Lindley later revised his original placement and moved the species to the genus "Oeceoclades" in 1833.
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 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 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".
