The Hainburg spring carnation ( Dianthus lumnitzeri ) is a species of carnation ( Dianthus ) within the carnation family (Caryophyllaceae). It is rare in Central Europe.
description
Vegetative characteristics
The Hainburger spring carnation is a perennial herbaceous plant that reaches heights of 20 to 30 centimeters. The stem is square and has blue-green prunings.
The basal and stem leaves are arranged opposite one another. The simple leaf blade is linear with a width of 1 to 3 millimeters . The narrowing of the leaf blade begins above the center.
Generative characteristics
The flowering period extends from May to June. Their stems usually have only one flower. The hermaphrodite flowers are radially symmetrical and five-fold. The outer sepals are blunt and briefly pointed. The five petals are white, rarely pale pink. The plate of the petals is 12 to 18 millimeters long and slashed to the middle.
Dianthus lumnitzeri is hexaploid or tetraploid with a chromosome number of 2n = 90 or 60.
ecology
The Hainburg spring carnation is a Chamaephyte or Hemikryptophyte .
Occurrence
Dianthus lumnitzeri is only known from relatively few locations in the Pannonian Floral Province . It is relatively common at the Locus classicus , the Hainburger Mountains in Lower Austria . There are several locations in the Little Carpathians in Slovakia. There are other occurrences in the Pilis - and in the Vértes Mountains northwest of Budapest . The populations in the Pollau Mountains in South Moravia are also assigned to Dianthus lumnitzeri , while the populations that follow from here to the northeast are assigned to Dianthus praecox .
It grows in rock and turf steppes over limestone (dry limestone lawn). It is limited to the colline altitude level . There are minor deposits in carbonate pioneer dry grasslands. In the Hainburg mountains is characteristic species of Diantho lumnitzeri-Seslerion albicantis. Important companion species are clump grasses such as Carex humilis and carpet shrubs such as Genista pilosa .
The Hainburg spring carnation is rare, but it is common locally. It is considered to be potentially endangered. It is completely protected in Lower Austria. Endangerment is caused by the natural rarity on the one hand, and on the other hand by population losses through natural succession (forest cover) and the destruction of the sites through material mining. Protected areas were designated to protect the species, and this species is also grown in culture.
Systematics
Dianthus lumnitzeri was first published by Johann Baptist Wiesbaur . The specific epithet lumnitzeri honors the old Austrian botanist Stephan Lumnitzer (1750–1806).
The Hainburger feather carnation belongs to the species group around the feather carnation ( Dianthus plumarius ) in the genus ( Dianthus ).
