- Abstract
Sisyrinchium is one of the largest genera in Iridaceae, comprising more than 200 species and native to Hawaiian Islands, Temperate and Subtropical America to Falkland Islands. In Bulgaria, the genus was first reported in 1972 with the species S. angustifolium. In 2020, during field work near the Oshtava village, Kresna district (SW Bulgaria), a species of Sisyrinchium was discovered. The taxon was identified as S. rosulatum. The aim of the present article is to report S. rosulatum as a new species to the Bulgarian flora and to provide data about its main distinguishing morphological characters and its distribution and habitats in Bulgaria. The genome size of the species, obtained from the Bulgarian accessions, is 1C = 1.00-1.08 pg which is congruent with earlier data from elsewhere. Based on field observations, it can be inferred that S. rosulatum is a naturalized, yet non-invasive alien species in the Bulgarian flora. A careful examination of the previously collected herbarium material of Sisyrinchium from Bulgaria revealed all specimens belong to S. rosulatum.
