Hladnikia

Hladnikia is a monotypic genus of flowering plants belonging to the family Apiaceae. Its sole species, Hladnikia pastinacifolia, is a Slovenian paleoendemite, restricted to the area of only 4 km, located in Trnovo Forest Plateau, karst plateau of Western Slovenia. German botanist Heinrich Gottlieb Ludwig Reichenbach named the genus after Carniolan botanist and founder of Ljubljana Botanical Garden Franz Hladnik.

== Description == Hladnikia pastinacifolia is a monocarpic herbaceous perennial plant, which takes a few vegetation periods to develop into a flowering plant. Individuals, which have erect flowering stem, can reach from 15 to 30 centimetres of height. At first plant's leathery and glossy leaves are simple shaped and arranged into rosettes. Later on, as their area increases, leaves also change shape into lobate. Hladnikia pastinacifolia resembles well-known celery (Apium graveolens), but has thicker foliage and shorter leaf stems. The species' root is long and lignified. The plant's flower has white, heart-shaped and 1 mm long petals.
