A contribution to the vascular flora of Bulgaria: new species record and chorological update

Abstract

The present paper discusses new data on the distribution of 15 plant taxa, native or alien to the vascular flora of Bulgaria. Allium urusakiorum is reported to Bulgaria for the first time. Five of the listed taxa, Thelypteris palustris, Isolepis supina, Cladium mariscus, Carex punctata, and Avena eriantha are of conservation significance at regional scale. The current invasive status of the alien to the Bulgarian vascular flora Mollugo verticillata is discussed. Additional nomenclature notes and comments on some neglected herbarium records distributed in the indexed Bulgarian herbaria were included to the text.
