Gustav Maass

Gustav Friedrich Hermann Maass (2 December 1830 – 28 April 1901) was a German botanist who was a native of Brandenburg an der Havel.

Within this association, he carried out extensive studies of flora found in areas surrounding the Ohre and Aller Rivers.

Results from these field studies were incorporated into Schneider's book Flora von Magdeburg.

Maass is credited with discovering several new species of blackberry, and for providing assistance to Wilhelm Olbers Focke (1834–1922) with the latter's 1877 treatise Synopsis Ruborum Germaniae.

Increasingly, from the mid-1880s, he combined his botanical trips with historical research, in particular investigations of megaliths and other prehistoric monuments, as well as studies of ancient villages and forts.
