BRYOLOGICAL NOTES ON A TRIP IN NORWAY. 93 



as the var. often is. A. nivalis, Hook. Horre pass and Mari- 

 stuen, common in alpine streams. 



Catharinea tenella, Røhl. Near Odde and Maristuen ; the 

 o^ plant and old fruit. It was much commoner near Maristuen 

 than C. undulata. 



Polytrichum sexangulare, Ehrh. Common on the moun- 

 tains near Maristuen and often with fruit: fruit small. 



P. commune var. perigoniale, Schp. Bratlandsdal and 

 Slutemyr near Maristuen. — The perichætial bracts and general 

 habit of the variety well marked, but with the apical cell of 

 the lamellae distinctly grooved and in the Slutemyr plant almost 

 typical. 



Buxhaumia apliylla, L. Wood by the Laera, Maristuen, 

 very sparingly. 



Ditrichum tenuifolium, Ldb. Bleja and the Nærodal. The 

 Bleja plant fruiting in company with Dicranella secunda Ldb., 

 the Nærodal plant more robust, but sterile. 



Rhabdoweisia denticulata, Brid. Odde c. fr., a rather 

 robust form. 



Cynodontium gracilescens, Schp. Maristuen, c. fr. Leaves 

 sharply papillose; some of them rather obtusely pointed; the 

 capsule pale, erect, striate on a straight seta. C. torquescens, 

 Limp., and C. fallax Limp, both c. fr. These two species which 

 are very closely allied to C. gracilescens were found very spar- 

 ingly near Maristuen. Some doubts might be raised as to 

 their value as species, but the specimens agree well with the 

 description given by Limpricht. C. laxirete, (Dixon) Grebe, 

 (C. polycarpum var. lœvifolium, Hagen). Rocks in the valley 

 below the Buar Brae, Odde c. fr. 



Dicranella secunda, Ldb. Bleja, c. fr., not very common. 



Dicranoweisia crispula, Ldb. Maabødal, Maristuen &c., 

 c. fr.; very fine near Maristuen, often with the leaves markedly 

 secund.
