" Notices of several recently discovered and undescribed 

 British Mosses," by G. E. Hunt, Esq. 



Oymnostortiuiin Calcareiini, N. and H., var. hrevifolium, 

 B. and S. Gyninostoinum viridulum, Bridel, 



Perennial ? dioicous ; stems coespitose, sparingly branched, 

 very slender, a third of an inch in height, of a reddish brown 

 colour below, upper part pale green, slightly glaucous; 

 leaves ovate or ovate lanceolate, with erect bases, thence 

 spreading, papillose, margin crenulated in the upper part; 

 cells in the upper portion of the leaf opaque, quadrangular, 

 in the lower portion elongated, sub-diaphanous; nerve 

 thick, papillose, extending almost to the apex. Male 

 flowers gemmiform, on very short axillary branches which 

 usually spring from an innovation ; perigonial leaves ovate, 

 suddenly acuminated, nerved to the apex. 



I have not seen female flowers or fruit. 



Habitat : Rocks at Blackball, near Banchory, where it was 

 discovered by Mr. John Sim. 



Entosthodon rainimum, Hunt, sp. nova. Annual, dioicous; 

 stems gregarious, erect, an eighth to a quarter of an inch 

 high; lower leaves obovate, margin reflexed, nerve thin, 

 vanishing below the apex ; upper leaves oblong, suberect, 

 subcanaliculate, margin recurved, crenulate in the upper 

 part, nerve rather strong, produced ahnost to the apex ; 

 areolae large, those of the lower part of the leaf elongate- 

 hexagonal, of the upper part shorter. 



Male plants with the flowers terminal, antheridia 6 to 8, 

 sessile, without paraphyses, perigonial leaves usually like 

 the upper stem leaves, but occasionally (together with all the 

 stem leaves) obovate, when they 'contain clavate, slightly 

 swollen paraphyses, without antheridia. 



Female plants with the flowers both terminal and in the
