Angraecum sesquipedale



From Wikipedia, the free encyclopedia
Angraecum sesquipedale


Angraecum sesquipedale ( /ˌsɛskwɨpɨˈdeɪliː/), also called Darwin's orchid, Christmas orchid, Star of Bethlehem orchid, and King of the Angraecums, is an epiphytic orchid in the genus Angraecum that is 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.[1]


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 then unprecedented
.


His prediction had gone unverified until 21 years after his death when the 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.

Sesquipedalia verba: Parole di un piede e mezzo. (Orazio, Ars poetica, 97).


Parole che riempiono la bocca. Si cita a proposito di certi oratori e conferenzieri che pare facciano un apposito studio per tirar fuori paroloni ad effetto, molte volte incomprensibili; in simili casi si potrebbe citare il motto: "Res non verba"( fatti, e non parole).
