Gentiana froelichii

Gentiana froelichii was described by German botanist Heinrich Gottlieb Ludwig Reichenbach[4] in his work Fl. Germ. Excurs. from 1832.[2][1] Species' name is dedicated to German doctor, entomologist and botanist Josef Aloys Frölich, who lived between 1766 and 1841, and is an author of monography from year 1796, dealing with genus Gentiana.[9] There are two reported plant subspecies; Gentiana froelichii subsp. froelichii and Gentiana froelichii subsp. zenariae.[2][9]

The species appearance is similar to that of related Gentiana clusii[10] and Gentiana frigida[11] species. The plant reaches from 5 to 10 cm of height.[12] Linear to oblanceolate gutter-like leaves are arranged into rosette. There are only a few stem leaves (usually one or two pairs[5]),[10] which are also visibly smaller.[12] The plant's characteristic are many non-flowering shoots growing nearby flowering shoot.[10]

A flowering shoot has one, less often two flowers.[5] This low growing plant's petals are bright blue[10][12] to violet[12] and its corolla lobes are not spread out like in many other Gentiana species (instead they are set upright).[10] Corolla measures from 3 to 4 cm,[10][12] with corolla tube being conically shaped. Calyx is bell-like, while having long, straight and sharpened calyx teeth. Anthers are fused together right next to style. The plant's stigma is lobate, its lobes being linear to oblanceolate.[10] The gentian's flowering period is between August and September.[10][13]

Gentiana froelichii has not yet been studied for the IUCN Red List.[14] It is thought the species is potentially threatened.[12]

In Slovenia and Austria it can be found as an endemic plant in eastern Karawanks and Kamnik–Savinja Alps. Gentiana froelichii also grows elsewhere; different subspecies occurs in Italian Julian Alps and Carnic Alps.[14] The plant grows beyond the tree line; its usual habitat consists of stony meadows and rock crevices, located in alpine zone.[10]
