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 recueillis dans les îles de France, de Bourbon et de Madagascar (usually abbreviated in botanic literature as Hist. vég. îles France), illustrated by many beautiful drawings. Other books followed: Mélanges de botanique et de voyages and Histoire particulière des plantes orchidées recueillies dans les trois îles australes de France, de Bourbon et de Madagascar (l'île de France is the present island of Mauritius and l'île de Bourbon is the present La Réunion). He did pioneering botanical work by his descriptions of orchids from this region: 52 species from Mauritius and 55 from La Réunion.
