Type specimens preserved in the Trèmols and Costa herbaria (BC)

Abstract

The Trèmols herbarium, preserved at the Botanical Institute of Barcelona, is one of the oldest herbaria in Catalonia, largely made up of European plants collected in 19th century. The digitization of this historical collection, currently in progress, has made possible to locate nomenclatural types of various authors, acquired through exchange. In this article, we indicate two syntypes (for <i>Fumaria caespitosa</i> Loscos and <i>Carex loscosii</i> Lange), and one isolectotype (<i>Polygala vayredae</i> Costa) in Trèmols herbarium. Additionally, we designate the lectotype of Polygala vayredae in the Costa herbarium and its isolectotype in the Vayreda herbarium.
