Imagem de Eritrichium nanum (L.) Gaudin

Descrição:

Slo.: triglavska neboglasnica - syn.: Myosotis terglouensis Hacq., Eritrichium nanum var. terglouensis, Eritrichum nanum - Habitat: stony ground with scattered grass patches, almost flat terrain, calcareous ground with some silicon, full sun, fully exposed to direct precipitations, elevation1.970 m (6.450 feet), average temperature 0 - 2 deg C average precipitations about 3.000 mm/year, alpine phytogeographical region. - Substratum: soil. - Comment: The English name of Eritrichium nanum tells the truth. The green 'pillows', covered by relatively large (up to 8 mm in diameter) sky-blue flowers, which are in Slovenia found mostly on bare white rock, offer unforgettable vistas. - Eritrichium nanum grows only at the highest elevations, in our mountains from 2.000 m to 2.800 m. Otherwise it can be found almost in the whole Alps, but always only on the highest peaks. This plant loves siliceous rocks and is much more common on granite rock particularly in West- and Southwest Alps; however it tolerates also calcareous ground, but it is relatively rare there. The species is supposed to be a Nunatakker relict (although this theory is nowadays more and more questioned), currently fighting for its survival in the coldest climate places of the Alps. In the scope of global warming it has probably little chances in future. In Switzerland it has already disappeared from about 20% of its known locations. - The plant was named Myosotis terglouensis by botanist B. Hacquet, one of the pioneers of botany of the Julian Alps in 1782, since he found it on Mt. Triglav. But later the name changed according to the naming rules in botany and the name of our highest mountain has been disassociated from this beautiful plant. - Ref.: (1) D. Aeschimann, K. Lauber, D.M.
