240 MR. G. E. HUNT ON MOSSES NEW TO BRITAIN. 



Fissidens viridulus, Jj. Probably the plant so named 

 in Bry. Brit, is a variety of F. pusillus. Inflorescence 

 synoicous. Banks at Clitheroe^ Dr. Wood. Near Bristol. 

 Dr. Wood first pointed out tbe synoicous inflorescence as 

 probably being a distinguishing feature in this species. 



Fissidens incurvus, Schwsegr. Inflorescence monoicous. 

 Male flower gemmiform,, at the base of the fertile stem ; 

 capsule curved, cernuous. The var. Lylei occurs in Che- 

 shire, though very rarely. Varying in a single habitat from 

 a minute plant, with 3 or 4 leaves, and setse 5 inch long, 

 erect capsule, to a plant twice the size, with capsule 

 slightly curved, and thence into true incurvus. The 

 typical incurvus is very common on shady banks in Che- 

 shire. 



Fissidens pusillus, Wils. Sandstone rocks. Difficult 

 to distinguish from the small state of F. Lylei. 



Fissidens crassipes, Wils. Monoicous ; male flower 

 either gemmiform at the base of the fertile stem, or ter- 

 minal on a long ofishoot. A much stronger plant than 

 the last, with larger leaves and thicker setse. Capsules 

 erect. IVequent in sluices. Mr. Boswell sends magni- 

 ficent specimens from Oxford, fully an inch long. 



Fissidens decipiens, De Not. {Fissidens rupestris, Wils. 

 MS.). Allied to F. adiantoides, but distinguished by its 

 pale-margined thickened leaves, more slender growth, 

 and shorter setse. Young plants, which, according to Mr. 

 Wilson, are the males, are abundant, nestling between the 

 wings of the leaves. Frequent on damp rocks and old 

 walls throughout the more elevated parts of Britain. 



Habrodon Notarisii, Sch. First discovered by Mr. J. 

 Nowell at Windermere, but not then distinguished. Killin, 

 Perthshire, Mr. A. M'^Kinlay, July 1865. Devonshire, 

 Mr. J. Nowell. On the trunks of elm and whitethorn. 

 Previously only known in Sardinia and Italy.
