location
Left bank of river Učja, next to the trail along north slopes of Učja gorge, about 1 km west of village Žaga, East Julian Alps (Posočje, Slovenia)notes Slo.: kimasta lepnica - syn.: Silene brachypoda Rouy - Habitat: Forest trail side, mixed forest, Ostrya carpinifolia dominant tree; steep mountain slope, south aspect; calcareous ground, among other tall herbs; in shade, elevation 480 m (1.575 feet); average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, alpine phytogeographical region. - Substratum: soil. - Comment: Silene nutans in broader sense is an extremely variable plant and insufficiently studied in Slovenia (Ref.: 1). It is an Euro-Siberian temperate floral element (Ref.4). The all-greenish plant as well its small, dropping flowers are inconspicuous particularly during the day. This is because its perianth-lobes are rolled inwards during the day making flowers really small. Only in the evening they unroll and the flowers become somewhat showier and also fragrant, which attracts their pollinators - moths. - Several subspecies of Silene nutans have been described with little consensus among botanists. Slovenian key as well as Ref. 2 (Austrian key) recognize two subspecies: Silene nutans L. ssp. nutans and Silene nutans ssp. livida (Wild.) Jeanmonod & Bocquet = Silene nutans ssp. insubrica (Gaudin) Soldano = Silene insubrica. The main distinguishing characters for Silene nutans L. ssp. nutans are: one-sided inflorescence and whitish outer side of the petals. For Silene nutans ssp. livida these are: all-sided inflorescence and olive green to dirty reddish-green outer side of the petals. - However, in practice the plants frequently don't want to obey books and keys. Most often I find something in between these two subspecies. An illustrative example are the pictures shown. The plants shown have clearly one-sided inflorescences and muddy greenish (not whitish!) petals on the outer side. So, to which subspecies they belong? Ref.: (1) A.
