location
Lazovški preval pass, below Mt. Debeli vrh, close to the trail from Planina Laz to Lazovški preval pass, East Julian Alps (Posočje, Slovenia)notes Slo.: Widderjeva murka - Habitat: alpine grassland, calcareous ground; open place, full sun, exposed to direct rain, altitude 1.940 m (6.350 feet), average precipitations about 3.000 mm/year, average temperature 0-2 deg C, alpine phytogeographical region. Substratum: soil. - Comment: Nigritella widderi was recognized as a new taxon in calcareous Northeast Alps in Austria about thirty years ago in 1985. In Slovenia it was first found in Julian Alps south of Mt. Triglav, 2.863 m in 2011 (Ref.: 6) . Up to now a few other stands have been found. All of them are in Julian Alps. To distinguish it from other red blooming Nigritella species is not always simple. The important typical traits are pink flowers at the bottom of the inflorescence, which are paler than the purple-red ones on the top of it. Also dark purple-red bracts, which can be seen among the flowers, are significant. The inflorescence is rather short and never distinctly cylindrical. There are also tiny morphological differences in rostellum, but it is almost impossible to observe them in the field without experience and a good hand lens. In addition, one has to pick the flowers to make such observations, which is prohibited, because the species is protected. Protected according to: Uredba o zavarovanih prostoživečih rastlinskih vrstah, poglavje A, Uradni list RS, št. 46/2004 (Regulation of protected wild plants, chapter A, Official Gazette of Republic Slovenia, no. 46/2004), (2004).
