Connaissance et exploration floristiques en Languedoc—Roussillon (France): Cartographie des points d'herborisations et répartition des Malvaceae pour l'Hérault

Abstract

The study of the frequencies by “commune” and ecological region of about 1800 floral locations recorded in Flora by Loret et Barrandon (1876; 1886) and in an unpublished work by L. Granel de Solignac et L. Bertrand based on the herbarium of Montpellier (MPU), enables us to estimate the density and the lacuna of the flora census in the department of Hérault. The information from both the Flora and the collections is value at the level of all the locations and also at the level of the locations indicated for the 24 species of Malvaceae inventoried in the department. The importance of the contribution of the collections is demonstrated: In 70 % and 85 % of the original locations. The maps of the distribution of the Malvaceae are also thrown. © Société botanique de France 1995.
