Angraecum Striatum
''Angraecum'', also known as comet orchid, is a genus of the family Orchidaceae native to tropical and South Africa, as well as Sri Lanka. It contains 223 species. Etymology Despite the genus's distribution being largely confined to Africa and its offshore islands, the genus name is a Latinisation of names, latinization of the Indonesian language, Indonesian and Malay language, Malay word anggrek ("orchid"), itself ultimately from Javanese language, Javanese ꦲꦔ꧀ꦒꦿꦺꦏ꧀ (anggrék, "orchid"). Description Angraecums are quite varied vegetatively and florally, and are adapted to dry tropical woodland habitat and have quite fleshy leaves as a consequence. Most are epiphytes, but a few are lithophytes. The long-lasting flowers are racemose and grow from the leaf axils. They are mostly white, but a few are yellow, green or ochre.

Angraecum Sesquipedale
''Angraecum sesquipedale'' , also known as Darwin's orchid, Christmas orchid, Star of Bethlehem orchid, and king of the angraecums, is an epiphytic orchid in the genus ''Angraecum'' endemic to Madagascar. The orchid was first discovered by the French botanist Louis-Marie Aubert du Petit-Thouars in 1798, but was not described until 1822. It is noteworthy for its long spur and its association with the naturalist Charles Darwin, who surmised that the flower was pollinated by a then undiscovered moth with a proboscis whose length was unprecedented at the time. Darwin's prediction went unverified for 21 years after his death, until Xanthopan, just such a moth was discovered and his conjecture vindicated. The story of its postulated pollinator has come to be seen as one of the celebrated predictions of the theory of evolution. Description ''Angraecum sesquipedale'' is a monopodial orchid and can grow to a height of . Its growth habit is rather similar to species in the genus ''Aerides'' ...
