location
Lower Trenta valley, between villages Soča and Trenta; Matevž's gorge, right bank of river Soča slightly downstream from hanging footbridge; East Julian Alps (Posočje, Slovenia)notes Slo.: apnenka - syn.: Nephrodium robertianum (Hoffm.) Prantl, Lastrea obtusifolia (Schrank) Janchen - Habitat: river shore in a narrow gorge, light mixed wood; moderately steep mountain slope, south east aspect; mostly in shade, humid place; calcareous ground; elevation 535 m (1.750 feet); average precipitations ~ 3.000 mm/year, average temperature 5-7 deg C, alpine phytogeographical region. - Substratum: soil. - Comment: Growing scattered and in groups of a few specimens. Gymnocarpium robertianum is a common fern in Slovenia; hence it is easy to find. It grows everywhere in the Alps and in almost all other European mountains also in low elevations. However, there exist two species - Gymnocarpium robertianum and Gymnocarpium dryopteris, both common and wide spread, which are very similar in appearance. Gymnocarpium robertianum loves basic, calcareous ground, while Gymnocarpium dryopteris prefers acid ground. Distinguishing both types of ground is not always a simple task for a layman and therefore usually not a handy characteristics for separation of both species. Fortunately there exists another difference, which is a clear-cut trait. Leaf stalks and underside of Gymnocarpium robertianum are covered by small but conspicuous glandulous hairs (see Picture 7b) while Gymnocarpium dryopteris has none. - Ref.: (1) M.A. Fischer, W.
