Cerastium carinthiacum Vest. ssp. carinthiacumCarinthian mouse-ear chickweed, DE: Krnten-Hornkraut Slo.: koroka smiljka Dat.: Aug. 1. 2015Lat.: 46.44283 Long.: 13.63977Code: Bot_906/2015_DSC8343Habitat: Crevices of a medium size limestone boulder on mountain pasture, southwest aspect, open place, full sun, exposed to direct rain and wind, average precipitations ~ 3.000 mm/year, average temperature about 0 deg C, elevation 2.040 m (6.700 feet), alpine phytogeographical region. Substratum: soil in a rock crevice.Place: Mt. Mangart region, right side slope of the main ravine of Mt. 'Mangart's flats below Mt. Mangart's tool road, near ez jezik pass, 2.055 m, East Julian Alps, Posoje, Slovenia EC.Comments: Cerastium carinthiacum ssp. carinthiacum is an endemic plant known only from east part of the Alps. Genus Cerastium is difficult to treat taxonomically and not sufficiently studied in Slovenia (Ref.:3). There are quite a few taxa, which grow in neighboring countries Italia and Austria, which haven't been found in Slovenia in spite of expectations and apparently sufficiently similar environment. Literature also disagrees in some points. For example Cerastium carinthiacum ssp. carinthiacum is described as an almost glabrous plant, while close alternative determination option Cerastium carinthiacum ssp. austroalpinum is described as densely glandular hairy in Ref.: 2 and Ref.: 4.. Just the opposite situation is stated in Ref.: 3. The plants photographed have conspicuous glandular hairs (see picture 1c) and fit to the description of Cerastium carinthiacum ssp. carinthiacum according to Ref.: 3. Ref.: 5 considers it a rare plant in the Julian Alps. Ref.:(1) D. Aeschimann, K. Lauber, D.M. Moser, J.P. Theurillat, Flora Alpina, Vol. 1., Haupt (2004), p 294.(2) M.A. Fischer, W. Adler, K.
