Galium setaceum Lam. and Sisyrinchium rosulatum E. P. Bicknell, Two New Species for the Albanian Flora, Distribution and Ecology

The Albanian flora includes 31 taxa in the genus Galium and one taxon in Sisyrinchium, the non-native S. angustifolium Mill. Here we present two new species for the Albanian flora, found at Krasta Park, Elbasan, May 2019. Galium setaceum Lam. was found on the southwestern side of Krasta Hill, in dry disturbed clearings of Pinus halepensis Mill. forest, on calcareous rocky substrate. Populations were small (lt%253B1m2) with a variable number of individuals. Sisyrinchium rosulatum E. P. Bicknell, which is native to southeastern North America, is the second new taxon for the Albanian flora. Two populations of were found in moist open disturbed grassy areas in P. halepensis forest. The first population detected was located in the northeastern side of Krasta Hill, while the second was located at the top of the Hill. For both taxa, specimens were collected and identified using multiple keys in the literature and specimens at the Albanian National Herbarium. Voucher specimens were deposited in the Albanian National Herbarium. In this paper we also present data on the distribution, ecology and habitat of these species, which enlarge the Albanian flora and the species distribution range, and illustrate the floristic diversity of Krasta Park
