Asplenium adulterinum (?!) (4850' N 1553' E)

Description:

2010.06.13 Lower Austria, Hollabrunn/Thaya National Park (300 m AMSL).Rare, that is if ID is correct.Sporangia in july/august.German name: Grnspitz-Streifenfarn (?!)ID: Fischer & al., Exkursionsflora (2008 3rd): ID is provisional as sporangia weren't developped yet and as young plants of Asplenium trichomanes show stems which are green at the tip (and will grow brown later) while those of A. adulterinum have green-tipped stems even on adult plants; I will try and back up ID through visiting the same place later this year - as A. adulterinum only grows on serpentine and magnesite this species is rather rare but the green tip still balances ID towards this species.
