THE BRYOPHYTA OF ICELAND 4(>/ 



FAM. SPLACHXACE.E. 



109. Dissodon splachnoides (Thunb.) Grev. 

 Taijloria lingulata (Dicks.) Lindb. 



Iceland (Morch)!. E. Iceland: Seydisfjordur. X. Iceland: Common 

 everywhere!. N\V. Iceland: Sugandafjordur!; Isafjordtirl; Armuli!; Arn- 

 gerdareyri!. W. Iceland: Brattabrekka !. S. Iceland: Barkarstadr!, 550 

 metres above sea-level. 



Grows on damp boggy ground, almost always mixed with other 

 mosses such as Hypnaceat, (Aiiclidiiim, Mccsia trichoides, Dichodonliiun 

 and Bryum ventricosiim. In N. Iceland, where it is most widely distri- 

 buted, it extends from the lowlands to a height of upwards of 600 

 metres above sea-level. Thus, near Husavik, it was very common in 

 Hypnum bogs, and near Akureyri it was found especially in bogs at an 

 altitude of 500600 metres. Near Seydisfjordur it was common from 

 about 100 metres upwards to the mountain heights. From the south- 

 western and southern part of the country it appears to be absent, or 

 is at any rate very rare; it was found in this part of the country only 

 in a Hypnum bog near Barkarstadr, at an altitude of 530 metres. 



110. Tetraplodon bryoides (Zoega) Lindb. 

 Tetraplodon mnioides (L. fil.) Br. eur. 



E. Iceland: Djupivogur!; Berufjordur!. N. Iceland: Akureyri (Car- 

 rington); Myvatn (Grl.)!; Reykir near Svinavatn (Grl.)!; Flateyardals- 

 heidi(St.)! ; near Eyjafjordur (6. D.) !. NW. Iceland: Dynjandi!. W. Iceland: 

 Husafell (Grl.)!; Brunnar (Grl.)!; Reynivcllir (Grl.)!; Kolvidarhol! ; Hafnar- 

 fjordur!. S. Iceland: Draupahlid .\Viinsted)!. 



Occurs here and there all over the country, but as a rule only in 

 single tufts on the bodies of dead animals. Near Djupivogur a large 

 tuft was found on a rotten fish. 



The fruit, w r hich occurs abundantly everywhere, ripens at the end 

 of June. 



111. Splachnum sphaericum (L. fil.) Swartz. 

 Splachnum pedanciilatum (Huds.) Lindb. 



Iceland (Morch)!; commonly distributed!. 



Grows on cow-dung in wet, marshy ground, often mixed with S. uas- 

 culosum, but is less frequent than the latter. It occurs most frequently 

 in North Iceland and also, to a certain extent, in East Iceland (Seydis- 

 fjordur and Vallanes), where it is met with abundantly in man}' localities, 

 it is somewhat rarer in South and South-west Iceland and probably 

 does not ascend higher than 300400 metres above sea-level. 



The fruit ripens rather irregularly, so that in the same tuft both 

 ripe and also quite young capsules may be found. The majority of the
