THE BRYOPHYTA OF ICELAND 463 



FAM. ORTHOTRICHACE.E. 



95. Amphidium lapponicum (Hedw.) Schinip. 



Anaectangium lapponicum Hedw. 



Very common. 



This species usually grows on damp rocks, especially in clefts and 

 crevices, but may also occur on a more dry substratum, for instance in 

 lava caves and among stones on heaps of debris at foot of cliffs Urd). 

 It grows both on bare rocks and on humus in rock-clefts, occasionally 

 also in gravelly soil or on earth, and even upon the sides of knolls in 

 bogs. It does not appear to ascend to any great height on the moun- 

 tains; it is most widely distributed up to 200300 metres above sea- 

 level, but it has, however, been found, although scantily, up to about 

 500 metres above sea- level. 



The fruit was usually ripe in the first half of June. 



96. Amphidium Mougeotii (Br. eur.) Schinip. 



Ancectangium Mougeotii Lindb.

 Hof near Eyjafjordur (O. D.!); Hrutafjordur (St.)!; M\vatn (Grl.)!. XW. Ice-

 South Iceland: common!. 



Common all over the southern and western part of the country 

 and probably also in NW. Iceland, certainly everywhere north of Isa- 

 fjordur. In N. Iceland it appears to be rarer, but occurs abundantly 

 near Eyjafjordur. In E Iceland it is common everywhere around Sey- 

 disfjordur and is probably also frequent elsewhere. It usually grows 

 in large, thick cushions on damp rock-sides in clefts, and by waterfalls, 

 but is also one of the species most commonly found in lava-caves. 



This species rarely ascends to any great height on the mountains. 

 In Esja it occurred 400 metres above sea-level, and has nowhere been 

 collected at a greater altitude. Only sterile specimens have been found. 



97. Uiota phyllantha Brid. 



Utota maritime C. M. et Kindb. 



Weissia maritima Britt. 



E. Iceland: Everywhere along the coast from Hornafjordur to Be- 

 rufjordur!. NW. Iceland: Frequent around Isafjordur!. W.Iceland: Snre- 

 fellsnes (H. J.)!; Stykkisholmur!; common near Reykjavik, Hafnarfjordur 

 and ever} r where around Hvalfjordur!. S. Iceland : Vestmannaey! 



This species is probably common everywhere along the coasts, 

 where it grows in company with Grimmia maritima quite close to the 

 sea-side. It is only rarely met with at a distance from the sea, as, for 

 instance, around Reykjavik, and in a few places in the lava-fields near 

 Hafnarfjordur. The reason why it has not been collected in North
