 Brachijthecinm cirrosum (Schwagr.) Schimp. 



SW. Iceland: Esja!; Kolvidarhol !, at an altitude of about 300 metres. 



In Esja it grew rather scantih 7 on a damp slope, in company with 

 Hypnum chrysophyllum. Near Kolvidarhol it grew abundantly on the 

 ground among grass and species of Carex. 



262. Eurhynchium piliferum (Schreb.) Br. eur. 



Hypnum piliferum Schreb. 



W. Iceland: Budahraun (H. J.)!; Alafoss near Reykjavik!; Hafnar- 

 fjordur!. SE. Iceland: Hornafjordur!. S. Iceland: Reykirdalur !, up to

 places up to about 300 metres above sea-level; between Thingvellir and 

 Geysir (Grl.)!; common around Thingvellir!; Drangshlid!; Vestmannaey !. 



Rather common in the South-western and Southern parts of Iceland. 

 It usually grows in protected localities, for instance in lava-clefts, but 

 occasionally, for instance near Reykir, it occurs on moss-grown slopes 

 in company with Hylocominm spp. Near Thingvellir it was found abun- 

 dantly in Almannagja, at the grass-covered bottom of the ravine. Only 

 sterile specimens have been found.

/ 



Hypnum Swartzii Turn. 



S. Iceland: Drangshlid (H. J.:!); Merkjafoss (F.)!; common on Fljots- 

 hlid and below Eyjafjall!; Reykirfoss!. SW. Iceland: Alafoss. 



This species was found only in S. Iceland, but was common there 

 on damp rocks, especially at the base of the sides of tuff rocks in clefts 

 and in damp caves. Only sterile specimens have been found. 



Note. Eurhynchium hians from Merkjafoss Jeg Feddersen) belongs 

 to E. Swartzii. 



Hypnum prcelongum is recorded from Iceland by Zoega. There 

 are no specimens of it in the collections, but perhaps it has been con- 

 fused with E. Swartzii 



264. Eurhynchium Stockesii (Turn.) Br. eur. 



Hypnum Stockesii Turn. 



S. Iceland: Drangshlid!; Hrutafell!; Holt!; Seljaland!; Vestmannaey 

 (H. J.;!). 



Rather common south of Eyjatjall and on Vestmannaey. It usually 

 grows rather scantily on the ground, between blocks of rock or in clefts. 

 On Vestmannaey it occurred in several places; among other localities 

 at the foot of cliffs, in company with Mnium undiilatiun and Lophocolea 

 cuspidata. Only sterile specimens have been found.
