I98 THE FLORA OF HALIFAX. 



Hypnum stellatum, Schreb. 



1840. Widdop. — 5. Gibson, Baines' Fl. 

 1888. Todmorden. — A. Stansfield, Lees' Fl. 



Hypnum uncinatum, Hedw. (H. aduncum, L. ; Amblystegium 

 aduncum, Lindb.) 



1775. /. Bolton. Boggy moors, frequent. — Herb. Leyl. 



Hebden Valley. — Herb. Nwl. ; ' rare ' — A . Stansfield, Lees' Fl. 



1892. Pecket Wood ; Hardcastle. — /. Needham. 



So much confusion prevailed among the older authors 

 between H . aduncum, L. = H. uncinatum, Hedw. ; and 

 H. aduncum (non L.) Hedw. = H. Kneiffii, Schp., that it 

 is scarcely safe to say which species the H. aduncum 

 recorded by Bolton, really is. After considering the 

 synonomy, and examining Nowell's and Leyland's 

 specimens it was decided to place all three records here. 



Forma plumosa, Ren. (var. plumosum, Schimp.) 



Pecket Wood, on rocks ; Hardcastle, in fruit. — /. 

 Needham (The Naturalist, March 1901, p. 75). This 

 form is commoner than the type about Hebden 

 Bridge. 



Var. plumulosum, Schimp. 



Among other mosses on damp rock, Pecket Wood ; on 

 the Scar, Hardcastle. — /. Needham (The Natural- 

 ist, March 1901, p. 76.) There are intermediate 

 forms between the type and these two varieties. 

 J. A. Wheldon remarks on one, "if. uncinatum 

 between type and f. plumosa Ren., nearest the 

 latter ; one of the plants which proves Renauld is 

 right in reducing var. plumosum to a mere forma." 



Hypnum fluitans, L. 



1840. In fruit, Stansfield Moor. — Baines' Fl. 



Redmires, Stansfield Moor. — Herb. Leyl. ; Herb. Nwl. 



In Wils. Bry. Brit, the author remarks, "a variety with 

 suberect capsules has been gathered by Nowell on 

 Stansfield Moor." 



1888. Heptonstall Moor. — A. Stansfield, Lees' Fl. 

 Group, amphibium, Ren. 



var. Jeanbernati, Ren. 



1890. In rill, Gibb Slack Moor, Wadsworth ; in
