Abstract

Justander was in order the third Demonstrator in Botany (1789–1794) at Åbo Akademi. The main duty of demonstrators were to instruct medical students on the subject of medicinal plants. Justanders personal history is not well known. He defended to both Carl Niclas Hellenius and Pehr Adrian Gadd one theses, and supervised one himself, in order to obtain a docentship at Åbo Akademi. In that one new species, Festuca obliqua, and its four varietes are described as new. These validly published names have completely been overlooked. All material was probably lost at the Great Fire of Åbo in 1827.
