Substratum: Sand and fine gravel among rocks.Place: Lower Trenta valley, between villages Soa and Trenta; right bank of river Soa, near farm house Matev, about 15 m off the river shore below the main road Bovec Vri pass, East Julian Alps, Posoje, Slovenia EC.Comment: Aethionema saxatile ssp. saxatile is not a common plant as its Slovenian vernacular name "navadna" (common) "kamnica" (growing on rocks) suggests. It is a quite tiny plant and hence probably also frequently overlooked. The species is primarily a Mediterranean floral element, but it grows also in almost the whole Alps and other European mountains (Ref.: 7). In several regions it is quite rare (Ref.: 2, 8) and protected. IUCN considers it a vulnerable species. In Slovenia it grows sparsely scattered all over the country. But it has been apparently found the most frequently in the Alps, just around Trenta valley. In Croatia one can find it in the mountains Velebit, but most frequently much southern in the mountains of the Adriatic Sea shores and particularly on island Bra (a very stony island with quite high mountains) (Ref.:6). Tiny flowers of Aethionema saxatile ssp. saxatile are usually reddish, pink or violet. They can be also almost white, but rarely. The plant is in any case a tiny beauty seldom encountered!Ref.:(1) A.
