Takhtajan system

A system of plant taxonomy, the Takhtajan system of plant classification was published by Armen Takhtajan, in several versions from the 1950s onwards. It is usually compared to the Cronquist system. It admits paraphyletic groups.

Systems

The first classification was published in Russian in 1954,and came to the attention of the rest of the world after publication of an English translation in 1958 as Origien of Angiospermous Plants. Further versions appeared in 1959 (Die Evolution der Angiospermen) and 1966 (Sistema i filogeniia tsvetkovykh rastenii).[1] The latter popularised Takhtajan's system when it appeared in English in 1969 (Flowering plants: Origin and dispersal). A further revision appeared in 1980.[2][3]
