ACHARIUS, ERIK (1757–1819), Swedish botanist, was born on the 10th of October 1757, and in 1773 entered Upsala University, where he was a pupil of Linnaeus. He graduated M.D. at Lund in 1782, and in 1801 was appointed professor of botany at Wadstena Academy. He devoted himself to the study of lichens, and all his publications were connected with that class of plants, his Lichenographia Universalis (Göttingen, 1804) being the most important. He died at Wadstena on the 13th of August 1819.
