On returning to Germany he became chair of the Hamburg Herbarium, before taking up the position at Kaiserslautern where he remained till retirement.
[2] Huber was one of the first scientists to challenge the traditional division of angiosperms into monocotyledons and dicotyledons, on morphological grounds.
His contributions did not meet a wide audience outside of his own country since he mainly wrote in German, and publishing in the Mitteilungen der Botanischen Staatssammlung München.
[4] When Dahlgren and Clifford published their study of families of monocotyledons (1985)[5] they developed and popularised Huber's concept, giving rise to the formation of a new order, the Asparagales.
Other important work deals with the Rosiflorae (sensu Dahlgren), the classification of dicotyledons and seed anatomy.
