- Abstract
In the speciality literature, the number of Alnus species varies between 30 and 35. However, by analysing the species present in different herbarium (Al. Beldie Herbarium from Romania, WU Herbarium from Wien and Harvard University Herbaria from U.S.A.), this number increases to 42. The most numerous Alder species present in these herbariums are Alnus incana and Alnus viridis (spread out on a vast natural range, namely Eurasia and North America), followed by Alnus serrulata (which can be found in North America). As such, the Alnus Genus is well represented in Asia (especially in China and Japan), as well as in North America or Europe. The analysis of vouchers present in different herbariums has significant contributions regarding the number of species from a certain genus, their spreading, as well as their particular characteristics. However, in order to obtain satisfactory results, a large number of herbariums is required, followed by an appropriate geographic distribution. In this regard, the BUCF Romanian herbarium is a good case study.
