Brachythecium Starkei, B, & S. Simodal. B. glaciale, B. 

 & S. Blejà. c. fr. Rather variable. B. reflexum, B. & S. Rocks 

 in woods, Odde and Maristuen c. fr. B. populeum, B. & S. 

 var. amœnum. Rocks near Lærdalsøren. 



Plagiothecium silesiacum, B. & S. Rotten pine trunk 

 Eide c, fr. P. striatellum, Ldb. Rotten birch stumps, Eide. 

 P. denticulahim, var. ohtusifolium, H. & T., Blejà, c. fr. P. 

 Müllerianum, Schp. Odde, Simodal Sec. A few capsules in 

 the Simodal. The moss was growing at Odde on the rotten 

 stump of an alder (Alnus incana) in company, with P. latebri- 

 cola. P. laiebricola, B. & S. Odde, c. fr. P. piliferum, B. 

 & S. ; Rocks below the Saddel, Maristuen. 



Amhlystegium Sprucei, B. & S. Cavern in the Simodal; 

 a slender bright green form. 



Hypnum fluitans (exannulatum) var. hrachydidyon, Ren. 

 A remakrable form of this plant occurred fruiting in the bog at 

 Slutemyr. It was for the most part dioicous, but some fruiting 

 stems bore c3^ flowers also. The leaves on the c/' stems and 

 on the branches of all the plants were short, shortly pointed and 

 subobtuse, erect or nearly so (as in f. orthophylla, Ren., var. 

 orthophyllum, Milde), and with scarcely any differentiation of 

 the leaves from H. pseudo-stramineum, Müll, The lower leaves 

 of the fertile stems were however falcate, and of the normal 

 form and structure in the exannulatum group. Mons. Renauld 

 thinks it may probably deserve varietal rank, and in that case 

 suggests for it the name var. Nicholsoni. 



H. incurvatum, Schrad. Near Husum, c. fr. H. Patientiœ, 

 Ldb. Common in many places. H. pratense, Koch. Marshy 

 ground, Blejà, rare. H.revolutum, Ldb. Blejà, rare; acumen of 

 the leaves rather more serrate than in British specimens. H. 

 hamulosum, B. & S. Not infrequent on rocks; also found on 

 tree trunks in the Nærødal and at Maristuen. H. hadium, 

 Hart. This pretty and distinct species occurred in several places 

 above Maristuen at an altitude of 4 to 5000 feet. H. ardicum.
