broadlh, wnlls incrassnled, slii^hHy and indistinctl}'^ or not al all pored, 

 rec'langular, clongalcd, along llic margins shorter, groiip of angular- 

 cclls brownish, small, not distinctly defincd, rcmoved from the nerve, 

 somelimes indislincl or wanling; nerve narrow, ^/is — ^/ao of base, 

 consisling of homogcnous cells, excurrent in a short or long, acute 

 subula. Perichælial-bract broad, sheating, of laxer texture, suddenly 

 conlracted to a subula -/s — Vs lenglh of the sheath. Seta very 

 shoil, pale, about twice the lenglh of capsule. Calyptra cucullate 

 with a tliick rostrum. Capsule immersed in the perichætum, ovato- 

 globose, wide-mouthed, fuscous, without stomata, sulcate when dry, 

 outer cells of exothecium very thickwalled, in the deepenings irre- 

 gularly rhombic and rectangular, in the walls elongated and narrow; 

 annulus persistent, of 2 rows of cells; lid orange, conic, with a 

 long, subulate, oblique beak; peristome suberect when dr}^ red, 

 teeth narrowlj' lanceolate-subulate, irregularly bifid or perforated. 

 Spores large (0,025 — 0,033 mm.), pale brownish-green, finally papillose. 

 Male inflor. below the perichætium, gemmiform, about 0,66 mm. 

 long, bract shortl}^ acuminate, inner obtuse. 



A distinct species, readily distinguished from all other European 

 Dicrana by the immersed capsule without stomata. My friend Mr. 

 H. Lindberg of Helsingfors, has kindly compared the Fæoese 

 specimen with the original specimen of Arctoa Anderssonii Wich. 

 in Professor S. O. Lindberg' s Herbarium, and informs me that 

 he has found no difference of value between them. The spores 

 of the Færoese specimen are a little smaller and the group of 

 angular cells in the leaves appears to be a little more distinct. 

 Nothing else!
