Louis-Marie Aubert Du Petit-Thouars
Louis-Marie Aubert du Petit-Thouars (5 November 1758, Bournois – 12 May 1831, Paris) was an eminent French botanist known for his work collecting and describing orchids from the three islands of Madagascar, Mauritius and Réunion. Introduction Petit-Thouars came from an aristocratic family of the region of Anjou, where he grew up in the castle of Boumois, near Saumur. In 1792, after an imprisonment of two years during the French Revolution, he was exiled to Madagascar and the nearby islands such as La Réunion (then called Bourbon). He started collecting many plant specimens on Madagascar, Mauritius and La Réunion. Ten years later he was able to return to France with a collection of about 2000 plants. Most of his collection went to the ''Muséum de Paris'', while some species ended up at Kew. He was elected member of the prestigious ''Académie des Sciences'' on 10 April 1820. Du Petit-Thouars is remembered as the author of the book ''Histoire des végétaux recueill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tahiti
Tahiti (; Tahitian ; ; previously also known as Otaheite) is the largest island of the Windward group of the Society Islands in French Polynesia. It is located in the central part of the Pacific Ocean and the nearest major landmass is Australia. Divided into two parts, ''Tahiti Nui'' (bigger, northwestern part) and ''Tahiti Iti'' (smaller, southeastern part), the island was formed from volcanic activity; it is high and mountainous with surrounding coral reefs. Its population was 189,517 in 2017, making it by far the most populous island in French Polynesia and accounting for 68.7% of its total population. Tahiti is the economic, cultural and political centre of French Polynesia, an overseas collectivity and an overseas country of the French Republic. The capital of French Polynesia, Papeete, is located on the northwest coast of Tahiti. The only international airport in the region, Faaā International Airport, is on Tahiti near Papeete.

Battle Of The Nile
The Battle of the Nile (also known as the Battle of Aboukir Bay; french: Bataille d'Aboukir) was a major naval battle fought between the British Royal Navy and the Navy of the French Republic at Aboukir Bay on the Mediterranean coast off the Nile Delta of Egypt from the 1st to the 3rd of August 1798.

The British fleet was led in the battle by Rear-Admiral Sir Horatio Nelson; they decisively defeated the French under Vice-Admiral François-Paul Brueys d'Aigalliers. Bonaparte sought to invade Egypt as the first step in a campaign against British India, as part of a greater effort to drive Britain out of the French Revolutionary Wars. As Bonaparte's fleet crossed the Mediterranean, it was pursued by a British force under Nelson who had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cycad
Cycads are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, that is, individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly and live very long. Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group. Cycads are gymnosperms (naked-seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones ( strobili), somewhat similar to conifer cones. Cycads have been reported to fix nitrogen in asso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycas Thouarsii
''Cycas thouarsii'', the Madagascar cycad, is an evergreen arborescent cycad in the genus ''Cycas''. It is named after a French botanist Louis-Marie Aubert du Petit-Thouars (1758—1831). Description The stem of this cycad resembles that of a palm, and grows 4–10 meters tall and up to 45 cm in diameter. The large photosynthetic leaves have spiral arrangement on the stem and are interspersed with many brown, hairy, triangular scale-like leaves. The photosynthetic leaves are pinnate, dark-green, somewhat glossy, and usually 150—300 centimeters long, with 60-120 leaflets per side. The leaflets are ''c.'' 17 cm long, lanceolate, with a slightly bent margin, and a midrib that is more prominent on the paler lower surface. The leaf-stalk is 40–50 cm long, and has two rows of spines along almost its whole length. The emerging leaves are hairy and show involute vernation; and the young leaves have a distinct bluish tint, which distinguishes it from its relatives '' ...

John Lindley
John Lindley FRS (5 February 1799 – 1 November 1865) was an English botanist, gardener and orchidologist. Early years Born in Catton, near Norwich, England, John Lindley was one of four children of George and Mary Lindley. George Lindley was a nurseryman and pomologist and ran a commercial nursery garden. Although he had great horticultural knowledge, the undertaking was not profitable and George lived in a state of indebtedness. As a boy he would assist in the garden and also collected wild flowers he found growing in the Norfolk countryside. Lindley was educated at Norwich School. He would have liked to go to university or to buy a commission in the army but the family could not afford either. He became Belgian agent for a London seed merchant in 1815. At this time Lindley became acquainted with the botanist William Jackson Hooker who allowed him to use his botanical library and who introduced him to Sir Joseph Banks who offered him employment as an assistant in his h ...
