Joseph Marie Henry Alfred Perrier de la Bâthie

From Wikipedia, the free encyclopedia

Joseph Marie Henry Alfred Perrier de la Bâthie (1873–1958) was a French botanist who specialized in the plants of Madagascar. He delineated the two chief floristic provinces of Madagascar (see Ecoregions of Madagascar). Some of his works include La végétation malgache (1921), Biogéographie de plantes de Madagascar (1936), and numerous volumes of the series Flore de Madagascar et des Comores (1946-1952).

The orchid genus Neobathiea (originally Bathiea) was named in his honor, as was the indriid lemur Perrier's Sifaka (Propithecus perrieri). Several species of Madgascar plants were named for him, including Erythrina perrieri, Ensete perrieri, Euphorbia perrieri, Melanophylla perrieri, Podocarpus perrieri, Takhtajania perrieri (originally Bubbia perrieri), and Xerosicyos perrieri.
