 On damp rocks. 

 Rhacomitrium heterostichum, Brid. {Trichostomum, Hedw. ; 

 Grimmia, C. Muell.) 

 Old walls near Halifax, frequent. — Herb. Leyl. 

 Not recently met with : Leyland's Herbarium specimens 

 upon which the Halifax record was established, have 

 been re-examined and the record confirmed ! 

 Rhacomitrium lanuginosum, Brid. (Bryum hypnoides, L ; 

 Trichosotmum lanuginosum, Hedw. ; Grimmia hypnoides, 



1775. /. Bolton. [Lindb.)

 Rhacomitrium canescens, Brid. (Trichostomum canescens, 

 Timm.) 

 1854. Heaths, banks and sandy lanes near Todmorden. — 



J. Nowell, Supp. 

 Possibly this indefinite record may be established on speci- 

 mens gathered on the Lancashire side of the county 

 boundary. Both Leyland's and Nowell's herbarium 

 specimens are from Sneddon Clough. 

 Ptychomitrium polyphyllum, (Dicks) Furnr. (Trichostomum, 

 Turn ; Glyphomitrium, Mitt.) 

 High Greenwood, Heptonstall. — Herb. Leyl. ; Baines Fl.

 1888. Hebden Valley.— Lees' Fl. 



1897. O n °ld wall, Midge-hole road, Hebden Bridge. —

 Hedwigia albicans, Lindb.) 

 1840. In many cloughs in the neighbourhood of Todmor- 

 den. — Baines Fl. Todmorden valley, etc. — Herb. Leyl. 

 Leyland's specimens are all right, but it is doubtful whether 

 they were collected on the Yorkshire side of Todmorden. 

 There is no specimen in Nowell's herbarium, and it is 

 omitted by Nowell from the Supp. to Baines' Fl.
