New findings and confirmation of the presence of two alien grass species in Croatia: Cenchrus longisetus and Sporobolus indicus

This paper provides new data concerning the presence of two alien grass species in Croatia based on a revision of herbarium material from ZA, ZAHO and ZAGR, literature data and on field observations. Two poorly documented alien grass species Cenchrus longisetus M. C. Johnst. and Sporobolus indicus (L.) R. Br., are confirmed for the country. Brief information on the species distribution in Croatia and a discussion of the alien and invasive status in the country is provided. Judging from the literature and field observations both species should be considered as naturalized, non-invasive species in Croatia. The text is illustrated with photographs from the new localities of both species. These new confirmed records allow us to better define the European and national distribution of the targeted species and offer new insights into the alien flora of Croatia
