Die Natürlichen Pflanzenfamilien


Die Natürlichen Pflanzenfamilien by Adolf Engler and Karl Anton Prantl is a complete revision of plant families down to generic level and often even further. As such it forms part of the Engler system of plant taxonomy.
Engler's starting point was that of Eichler who had been the first to use phylogenetic principles, and reflected the new post-Darwinian perspective, although Engler himself did not think that his was. His modified Eichler schema first appeared in 1886 in his Guide to Breslau Botanic Garden.
Die Natürlichen Pflanzenfamilien appeared in 23 volumes. An incomplete second edition was issued in 28 parts, although Engler had died in 1930. It is still considered one of the few true World Floras.
