Josef Bogner in the context of the history of aroid systematics: a personal view  — page 5

 

Simon Mayo

 

ABSTRACT

A brief account is given of some major events in the history of aroid taxonomy, setting Josef Bogner's manifold contributions in their historical context. Josef Bogner takes his place as the true successor to those past giants of aroid systematics, Heinrich Wilhelm Schott and Adolf Engler.

Josef Bogner’s Influence on Paleobotany — page 41

 

Ruth A. Stockey, Georgia L. Hoffman, and Gar W. Rothwell

 

ABSTRACT

Josef Bogner's energy and enthusiasm helped to bring about a great expansion in our knowledge of the fossil record of Araceae, and of other monocots as well. Building on his encyclopedic knowledge of the biology of extant aroids, Josef knew that fossils are essential to understanding the evolution and biogeography of the family through time. His tireless scrutiny of putatively araceous fossils increased the confidence in their affinity (or lack thereof) to Araceae, and his delight in each newly discovered fossil inspired many paleobotanists, including the authors.

Josef Bogner — and the genus Cryptocoryne  — page 83

 

Niels Jacobsen

 

ABSTRACT

For more than 50 years, besides studying most of the genera in the Araceae, Josef Bogner also devoted much time to the genus Cryptocoryne, both field observations where he has seen more than 40 taxa in their natural habitats and in the cultivation of most of the species. He was an active member of informal groupings, and besides writing or co-authoring more than 40 papers on Cryptocoryne, he also promoted other people’s work, and has been involved in all together more than 100 articles on Cryptocoryne.
