fruits ripen during July; near Se3'disfj6rdur many were found to be ripe 

 on July Ist, and in South Iceland ripe capsules were collected between 

 10—15 June. 



S])lachmim teniw is rccorded byGliemann to have been collected 

 bj' Morell, but the specimens in thc herbarium collected by Morch 

 belong partly to Sj)lachniiin sphæricuiu and partly to S. vasculosiim. 



112. Splachnum vasculosum L. 



Commonly distributed. 



Like the preceding species it grows. often abundantly, on cow-dung 

 in wet marshy ground. It is most frequent in the lowlands, but ascends 

 also as far upwards as to the mountain heights. Thus at Seydisfjardar- 

 heidi it was common up to about 600 metres above sea-level, and in 

 NW. Iceland also it was found as far upwards as about 500 metres. 

 Such forms from mountain heights are as a rule low in growth and 

 have short setæ. 



As is the case with Splachnum sphæricnin the fruit ripens at diife- 

 rent times during the course of the summer, from the flrst half of June 

 into August. 



Splachmun amjnillaceiim, as recorded to have been found by Koen i g, 

 is undoubtedly nothing else but S. vasculosum. 



FUNARIACEÆ. 

 113. Funaria hygrometrica L. 



Commonlj' distributed all over the countrj'. 



It usually grows on pcaty ground, associated with Dicranella crispa, 

 Polytrichnm (/racilc, P. jiiniperimim, Bryiim spp., etc, but is also found 

 on humus-covered rocks and on tuff". It does not occur abundantly, as 

 a rule, and it does not ascend to an}' great height, doublless not higher 

 than to an altitude of 300 — 400 metres. The fruit ripens in the be- 

 ginning of August. The spores vary considerably in size in this species, 

 from 0.011 to 021 mm., in piants which otherwise show no deviation 

 from the type. 



114. Entosthodon ericetorum (Bals. et De Not.) Br. eur. 

 Funaria obtusa (Dicks.) Lindb. 



W. Iceland: Kleppjarnsreykir in Reykholtdalur!; Englandshver!. In 

 both piaces with ripe fruit (25—30 July). 



This species grew in the above localities on warm ground. Near 

 Englandshver it grew along the outlet of a spring. Near Kleppjarns- 

 reykir it was found both on a stene standing in water of a temperature 

 of about 50^, mixed with Blindia aciita, Anenra multifida, Anthoceros 

 and Scapania irrigua, and also on warm, damp ground mixed with 

 Fissidens osmiindoides.
