Saxifraga squarrosaSlo.: nasreni kreDat.: Aug. 5. 2013Lat.: 46.43865 Long.: 13.64407Code: Bot_739/2013_IMG3883Habitat: Stony alpine pasture, modestly south inclined mountain slope, growing on large calcareous boulders scattered around, full sun, wind swept terrain, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 1-3 deg C, elevation 1.975 m (6.500 feet), alpine phytogeographical region. Substratum: soil in rock crevices of stony faces and large boulders. Place: Mt. Mangart flats, ~100 m north of Mangart alpine road when it passes Red rock region, Julian Alps, Posoje, Slovenia ECComment: Saxifraga squarrosa is endemic to southeast Alps and one of the most beautiful, high-elevation, late-summer flowering plants in Julian Alps. It is quite a common species on Mangart flats. One can find it almost on every big enough calcareous boulder, which are abundantly laying at the foot of Mt.Mangart's west face. A single small and dense cushion can often have more than hundred relatively to the leaves quite large flowers. Sometimes, like miracle, a cushion apparently grows right from solid rock. Indeed, very small rock crevices suffice to this plant to thrive successfully under harsh high-mountain sun rays and on the most exposed and wind and rain swept places. A very similar close-relative, Saxifraga caesia, also grows in the same region and on similar places. It differs from S. squarrosa mostly in details of very tiny leaves and flower steam hairs. Reliably distinguishing between both species without a good hand magnifier is sometimes quite a challenge.Ref.:(1) M. A. Fischer, W. Adler, K.

Saxifraga oppositifolia ssp. oppositifoliaL., syn.: Saxifraga murithiana, Saxifraga rudolphianaPurple saxifraga, DE: Purpur-Steinbrech, Gegenblatt-SteinbrechSlo.: nasprotnolistni kreDat.: June 17. 2014Lat.: 46.43986 Long.: 13.64561Code: Bot_813/2014_DSC1837Habitat: among rocks, northwest oriented scree slope; open, sunny place, relatively humid, acid soil, calcareous/siliceous rock, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 0-2 deg C, elevation 1.990 m (6.530 feet),alpine phytogeographical region. Substratum: soil among rocks.Place: Mt. Mangart's flats, scree slopes west of Mt. Mangart, East Julian Alps, Posoje, Slovenia EC Comment: Saxifraga oppositifolia is a jewel of Slovenian alpine flora. To me, it is the most beautiful species of genus Saxifraga among numerous others I know. This Arctic-Alpine floral element has been pushed by glaciers far south from its original distribution in Arctic during last Ice age and then, after the glaciers had melted, left only on the highest peaks of the Alps. Saxifraga oppositifolia is the highest climbing plant of the Alps found at 4.505 m (14.776 feet) elevation on Mt. Dom in Switzerland (Ref.:4). In Julian Alps it hardly descends below 2.000 m but ascends right the top of Mt. Triglav at 2.863m (9.391 feet).So unique to me and at the same time the commonest flower to kids in Greenland!Ref.:(1) A.

Saxifraga stellaris ssp. alpigena TenesyStarry Saxifrage, DE: Sternbltiger SteinbrechSlo.: zvezdasti kreDat.: July 22. 2008Lat.: 46.43846 Long.: 13.63398Code: Bot_286/2008_DSC2012Habitat: road side; almost vertical rocks, thickly overgrown with mosses, over which water is trickling; south aspect; calcareous rock; full sun; elevation 1.780 m (5.850 feet); average precipitations ~ 3.000 mm/year, average temperature 1-3 deg C, alpine phytogeographical region. Substratum: soil in rock crevices.Place: Mt. Mangart region, somewhat before the last tunnel of alpine tool road to Mt. Mangart's pass, East Julian Alps, Posoje, Slovenia EC Comment: Saxifraga stellaris ssp. alpigena is a very small, tender plant not frequently encountered by humans. It too perfectly signifies an antithesis of modern 'Big is beautiful!'. Yet, to those, who are willing to kneel down and look it from close, it becomes a source of joy and admiration. The plant keeps with very moist places high in the calcareous mountains, and since such habitats are not many it is not frequent. On the other hand, it is also not a rare plant. It is very broadly distributed. It grows in the whole Alps and other central and southern European mountains including whole Balkan Peninsula as well as in Arctic regions of America and Eurasia. Very similar relative Saxifraga stellaris ssp. stellaris exists, which replaces it in the North Europe. Ref.:(1) M.A. Fischer, W. Adler, K.

Saxifraga hostii ssp. hostii TauschHost's Saxifrage, DE: Hosts SteinbrechFamily: SaxifragaceaeSlo.: Hostov kre, Hostov kamnokreDat.: July 4. 2016Lat.: 46.21123 Long.: 13.55172Code: Bot_983/2016_IMG0705Picture file names: from Saxifraga-hostii_raw_20 to Saxifraga-hostii_raw_28.Habitat: stony roadside of a dirt road; calcareous, skeletal, stony ground, sunny and dry place, moderately inclined mountain slope, south aspect; exposed to direct rain; elevation 1.300 m (4.260 feet); average precipitations ~ 3.000 mm/year, average temperature 3-5 deg C, pre-alpine phytogeographical region. Substratum: soil among rocks and in rock crevices.Place: Next to the dirt road from village Livek to Mt. Matajur, near Planina Matajur, East Julian Pre-Alps, Posoje, Slovenia EC. Comment: Saxifraga hostii ssp. hostii is an endemic member of large genus Saxifraga containing numerous marvelous, mostly alpine pants. It is actually not a true high mountains species, since it can be found fully developed and in full bloom in Trenta valley below 500 m elevation. But it also climbs to alpine elevations well above 2.000 m. Habitus, leaves and inflorescence are much similar better known Saxifraga crustata, but it is larger in all its parts. The tallest plants can be more than 50 cm high and hence belong to the tallest members of this genus in the Alps. It can be found in northeast Italy, Slovenia and south Austria. Actually it is a sub-endemic plant because one can find it also in some places of Dinaric Mountains (Ref.1.). Slightly different subspecies Saxifraga hostii ssp. rhaetica grows in a limited region of south Alps in Italy.Flowers of Saxifraga hostii ssp. hostii are generally white, however sometimes the petals are decorated with beautiful, tiny red dots as shown in my picture. Such dots appear also on other species of this genus. Saxifraga hostii ssp hostii is a perennial plant. During the winter, if not covered by snow, its leaves get beautifully colored. Ref.:(1) D.
