Hladnikia is a monotypic genus of flowering plants belonging to the family Apiaceae. [3] Its sole species, Hladnikia pastinacifolia, is a Slovenian paleoendemite, [4] [5] restricted to the area of only 4 km2, located in Trnovo Forest Plateau, karst plateau of Western Slovenia. [6] German botanist Heinrich Gottlieb Ludwig Reichenbach named the genus after Carniolan botanist and founder of Ljubljana Botanical Garden Franz Hladnik. [4] [7]

Description

Hladnikia pastinacifolia is a monocarpic herbaceous perennial plant, which takes a few vegetation periods to develop into a flowering plant. [6] Individuals, which have erect flowering stem, can reach from 15 to 30 centimetres of height. [8] 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. [6] [8] Hladnikia pastinacifolia resembles well-known celery (Apium graveolens), but has thicker foliage and shorter leaf stems. [4] The species' root is long and lignified. The plant's flower has white, heart-shaped and 1 mm long petals. [8]

Not much is known about the plant's exact breeding system. This plant species is entomophilous and has multiple different pollinators. It is thought that outcrossing happens occasionally. [6] The species flowering period is between Mai and July. [4] After successful pollination seeds that don't have any special dispersal adaptation develop between the end of August and into September. A fruit is a schizocarp, which after maturing splits into two 4 mm sized mericarps, [6] 2 mm wide. [8]

Hladnikia pastinacifolia chromosome number is 2n = 22. [8]

Distribution and conservation

The plant is a Slovenian paleoendemic species restricted to small area (4 km2) in Trnovski gozd. There these plants grow only on southern slopes of the plateau and two isolated areas located 9 km away on the northern slopes. [6] As the plant species is not a habitat specialist its growing areas are various; Hladnikia pastinacifolia was found on stony grasslands, rock crevices and screes. Laboratory molecular analyses have shown that Hladnikia pastinacifolia is a Pleistocene survivor in situ. [8]

Even though its population trend is labeled as stable by IUCN Red list, it has data deficient (DD) conservation status. [9] [1] Among mentioned threats are human intrusions and disturbance (such as recreational activities) as well as natural system modifications. [1] The Trnovo Forest Plateau is listed as Natura 2000 site. [9] [10] Because of its small area of distribution and different threats the species is studied for possible cryopreservation. [5] [11] [12]
