Species Ehrharta triandra

For Jakob Friedrich Ehrhart (1742–1795), Swiss-born German botanist and naturalist. He studied botany at Uppsala University (1773–1775) under the guidance of Linnaeus, before returning to Hanover where Linnaeus’s son was director of the Botanical Garden. Ehrhart was one of the first botanists to publish exsiccatae (= plant collections, precisely identified, named and labeled), for various botanists or institutions. From 1780–1793 he produced seven series of these exsiccatae, each of about 1 620 species. He also had his own general collection (Hortus siccus) of about 3 300 plant species. A set of these collections are kept in the herbarium of Moscow University. He was supposedly the first person to use the rank of subspecies in botanical nomenclature.
