SUMMARY Asplenium trichomanes L. found in Iceiand by Eythor Einarsson Museum oj Natural History, Reykjavih Asplenium tnchomanes L. was first recorded from Iceland, without any locality, by Hornemann (1837), and, most likely, the record was based on information given to him, or specimens collected there, by the brvologist Axel Mörch, who stayed in Iceland during the summer of 1821. Babington (1871) records it as íound in Budahraun in Snæfellsnes, West-Iceland, by Mörch. Grönlund (1874) also records it from Budahraun, and says that specimens from there are found in Mörch’s herbarium in Copenhagen. Twenty five years later, however, no Icelandic specimens of this spicies are in evidence in museums (Jónsson, 1899), and since it has been searched for in vain in Budahraun by many botanists. Therefore it was thought safe to exclude it from the Icelandic flora (Gröntved, 1942). July lOth 1961, the present author collected Asplenium trichomanes L. at Skaftafell in Öræfi, Southeast-Iceland, where it had been found, but not deter- mined, by Mr. Halfdan Björnsson from Kvisker in Öræfi. At Skaftafell Asplenium trichomanes L. is growing in rock crevices at the altitude of ca. 100 m, where it was doing well and richly fructifying. Tlie specimens collected are 8—26 crn high, on the average ca. 15 cm higli. Thus Asplenium trichomanes L. really belongs to the Icelandic flora.
