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.

Cerastium strictum Haenke, syn.: Cerastium arvense ssp. strictum (Haenke) GaudinField Chickweed, DE.: Steif-Aker-HornkrautSlo.: toga smiljkaDat.: May 22. 2014Lat.: 46.35935 Long.: 13.70588Code: Bot_798/2014_DSC0890Habitat: once per year mowed sandy grassland, sandy roadside, flat terrain, calcareous ground, full sun, dry place, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 530 m (1.750 feet), alpine phytogeographical region. Substratum: sandy soil.Place: Lower Trenta valley, next to the road Bovec-Trenta, between villages Soa and Trenta, near 'Otokar', Trenta 4 farm house, East Julian Alps, Posoje, Slovenia EC Comment: Many members of the large genus Cerastium seem to me extraordinarily tender and beautiful, particularly those which grow in the harshest high mountain conditions in subalpine and alpine elevation. The striking contrast between this apparent inner tenderness and outer austerity seems absurd, not in a sense of something, which is not true or possible, but in a sense of something, which goes beyond human reason. Cerastium strictum is not a high alpine plant; nevertheless it is not less beautiful. The plants photographed certainly belong to the group Cerastium arvense agg., but splitting this aggregate down to species level with certainty is yet un unresolved problem for me. Different botanists have different approaches to this taxonomically critical group and hence it is not surprising that Ref.:(1), which divides this aggregate into four species, openly admits that the key presented is rather an attempt than a final solution and that this group obviously requires further detailed studies. In spite of this following this key and, based on relatively low plants and short leaves of about 15 mm length (the most probable alternative Cerastium arvense ssp. arvense has up to 40 mm long leaves) I decided for Cerastium arvense ssp. strictum.Ref.:(1) M.A. Fischer, W.
