who helped to develop better ways of classifying plants.

Life and work

Rivinus was born in Leipzig, Germany, and studied at the University of Leipzig (1669–1671), continued his studies in the

University of Helmstedt The University of Helmstedt (german: Universität Helmstedt; official Latin name: ''Academia Julia'', "Julius University"), was a university in Helmstedt in the Duchy of Brunswick-Wolfenbüttel that existed from 1576 until 1810. History Found ...

(where he received M.D. in 1676). In 1677, he started lecturing in medicine at the University of Leipzig, in 1691 appointed to two chairs, that of physiology and of botany, and made the curator of the University medical garden. In 1701, he became professor of pathology, in 1719, professor of therapeutics and permanent dean of the Faculty of Medicine. The same year he became a Fellow of the Royal Society. Because of his interest also in astronomy, by the last decade of his life (around 1713), Rivinus was nearly completely blind from looking at sunspots. He died in Leipzig. In his ''Introductio generalis in rem herbariam'' and three books on the plant orders (which comprised but a small part of the whole projected work on a methodical description of plants), Rivinus introduced several important innovations which were later used by other botanists (

Joseph Pitton de Tournefort Joseph Pitton de Tournefort (5 June 165628 December 1708) was a French botanist, notable as the first to make a clear definition of the concept of genus for plants. Botanist Charles Plumier was his pupil and accompanied him on his voyages. Lif ...

and Carl Linnaeus among them). He classified the plants according to the structure of the flower. Like John Ray he extensively used dichotomous keys which led first to the higher groups, which he called higher genera ''(genus summum)'' of plant orders ''(ordo)'', and then to the lower genera. Along with

, Rivinus was the first to apply consistently the rule that the names of all species in a genus should start with the same word (generic name). If a genus contained just one species, the generic name would be its only name. If there were more than one species in the genus, their names should consist of the generic name followed by ''differentia specifica'' (a brief diagnostic phrase). His nomenclature differed from de Tournefort's in not using a diagnostic phrase with the first plant of a genus, adding ''differentiae'' only to the second and subsequent plant species. He corresponded with John Ray on matters of plant classification.
