August Wilhelm Eichler , also known under his Latinized name , Augustus Guilielmus Eichler (22 April 1839 – 2 March 1887), was a German botanist who developed a new system of classification of plants to reflect the concept of evolution . His author abbreviation in botany is Eichler .
4-645: Choripetalae Eichler (1876), is a descriptive botanical name used in the Eichler and Wettstein systems to categorize a group of flowering plants . It represents one of two subdivisions within the Dicotyledones , with the other being the Sympetalae . The latter have fused petals (sympetaly) which distinguishes them from the free, unfused petals of the Choripetalae. Thus if the petals are free from one another in

It was the first to accept the concept of evolution and therefore also the first to be considered phylogenetic . Moreover, Eichler was the first taxonomist to separate the Phanerogamae into Angiosperms and Gymnosperms and
