Campylopus atrovirens, De Not. Bratlandsdal, a very 

 green form with the upper cells of the leaves rather shorter than 

 usual. 



Dicranodontium longirostre, B. & S. Wet rocks by the 

 Laatefos: a very tall robust form quite eight inches high. 



Dicranum fulvellum, Sm. Bleja c. fr., apparently rare near 

 Maristuen. D. hyperhoreum, G. M. Rocks by the Maristuen- 

 fos and on the summit of the Saddel c. fr., the plant from the 

 Saddel poor, the other much finer. Our specimens differ very J 

 markedly from D. fulvellum, Sm. in the more robust habit 

 larger leaves ending in a rigid, highly glistening bristle point, 

 and much larger stouter capsule, deeply furrowed and pachyder- 

 matous. The calyptra also is large, inflated, and very glossy, 

 and the spores which in D. fulvellum range from 15 to 20 f.i., 

 reach the size of 30 /n. in D. hyperhoreum, averaging about 25 

 to 27 f,i. The British plants referred to Arctoa hyperhorea by 

 the authors of the Bry, Eur. and other writers all belong to D. 

 fulvellum. The confusion between the two has probably arisen 

 for the most part from the description of the latter species in the 

 Bry. Eur. and elsewhere, as having smooth capsules, whereas 

 they are in reality always or nearly always more or less striate 

 or furrowed. 



D. elongatum, Schleich. Maabødal c. fr., Maristuen c. fr. 

 Common and fruiting freely on rocks by the Maristuen fos. Var. 

 Sphagni (Wahlen.) an attenuated form with the upper cells of 

 the leaves more elongate. 



D. fuscescens Turn. A form occurred on the Saddel with 

 the cells more porous in the upper part of the leaf, which 

 was almost smooth. D. Bergeri, Bland. Common in bogs, often 

 sterile, but c. fr. at Slutemyr. 



Grimniia apocarpa var. alpicola H. & T. Wet rocks 

 Maristuen c. fr., well marked. Var. gracilis W. & M, Fine & 

 well marked near Odde; nerve rough at the back. G. conferta 

 FuNCK. Simodal, c. fr. : a small delicate form. G. funalis,
