Matteuccia struthiopterisOstrich FernSlo.: navadna peruaDat.: June 8. 2013Lat.: 46.37746 Long.: 14.03571Code: Bot_722/2013_IMG3537 Habitat: almost flat bottom of a narrow gorge, northeast oriented, mixed wood, mostly Picea abies, Acer sp., Ulmus sp., Corylus avellana, Lonicera sp., Sambucus sp., calcareous ground, mostly in shade, high air humidity, average precipitations 1.600-1.800 mm/year, average temperature 6-8 deg C, elevation 750 m (2.450 feet), alpine phytogeographical region. Substratum: soil.Place: Pokljuka gorge, near village Gorje, East Julian Alps, Gorenjska, Slovenia EC Comment: Growing in large groups of many species. The largest population I've ever seen (2). This fern, not really common in Slovenia, is not difficult to recognize based on its characteristic narrow funnel shaped growth, size, and two different type of leaves. Only sterile leaves are shown on my pictures. Fertile ones, appearing later in the season, are brown, much narrower and growing straight upwards.
