Sisyrinchium micranthum (Iridaceae), a New Alien Record from Türkiye

Sisyrinchium is one of the largest genera in the Iridaceae family, including over 200 taxa. It is native to regions ranging from the Hawaiian Islands through temperate and subtropical areas of the Americas, extending down to the Falkland Islands. S. angustifolium Mill. is only recorded from Artvin, Kemalpaşa (Türkiye) from this genus. A newly allien species, S. micranthum Cav., has been reported as a new taxon for the Flora of Turkey from the eastern black sea region of Türkiye. S. micranthum is morphologically distinguished from S. angustifolium by urceolate-campanulate perianth, broadly acuminate tepal, 0.7–2 mm wide of node, 2–10 cm first internode, broadly acuminate petal apex and size of the capsule. Diagnostic characters, description and photographs are given in the manuscript. The distribution and habitat in Türkiye of the new record is determined. Taxonomic and conservation status of this species are evaluated.
