Ornithogalum sibthorpii Greuter

Taxonomy: Fam. Asparagaceae// Genus: Ornithogalum/ Species: Ornithogalum sibthorpii Greuter. The taxonomic classification is given according to The Euro+Med PlantBase (Raab-Straube, 2022+).

The determination was based on the botanical keys provided by Zahariadi (1980 in Tutin et al.) and Diklić (1975 in Josifović). The prior lists it as Ornithogalum sibthorpii Greuter, while the later as Ornithogalum nanum Sm. Both names refer to the same taxon, but O. nanum used in older literature is considered illegitimate. According to The Euro+Med Plantbase (Raab-Straube, 2022+), the accepted name is O. sibthorpii.

Lifeform: Bulbous perennial; Geophyte according to the  Raunkiær system.

The Euro+Med PlantBase (Raab-Straube, 2022+) considers O. sigmoideum a separate species with Asiatic distribution.
