THE FLORA OF HALIFAX. 1 65 



Wet banks, Todmorden. — Herb. Nwl. 



1840. Wet rocks and sides of streams, very common in the 

 Halifax district, and in the Vale of Todmorden. — Baines 

 Flo. Not rare. •/. Norn ell, Sup p. 



Not uncommon : Crimsworth Dean, High Greenwood, 

 Hardcastle. — /. Needham ; H. T. Soppitt ! Many places 

 in Booth Dean, Rishworth ; Ogden Clough ; Gosport 

 Clough, Stainland ; Blackshaw Clough, Soyland, etc. ! 



Dichodontium flavescens, (Dicks) Lindb. (Dicranium flavescens, 



Stanelly Clough. — /. Nowell, Brit. Moss- Flo. [Turn. 



Dripping bank, river side, Hebden Bridge (opposite Hollins, 

 Heptonstall). — J. Needham. 



Nowell omits the Stanelly Clough record in Baines' Supp., 

 nor are there any specimens in his moss herbarium. 



A much rarer plant than pellucidum with us. There are 

 fruiting specimens in Herb. Leyl. from Shedden Clough 

 1834, which have been re-examined. Gibson records it in 

 Baines' Flo. from the same locality. Both species are 

 variable in their leaf characters, and it is not always safe, 

 in the absence of capsules, to refer forms approaching 

 flavescens in cell structure to that species. 



Shedden Clough lies about a mile beyond the county 

 boundary in the direction of Burnley. 



Dicranella heteromalla, (Dill. L.) Schp. (Bryum, Dill. L., 

 Dicvanum, Hedw.) 



1775. J.Bolton. Stansfield Moor ; Ogden, etc. — Herb. Leyl. 

 Banks at Todmorden.— Herb. Nwl. 



Very common on banks in woods, doughs, and way-sides, 

 etc., throughout the parish, growing in dense, dark or 

 yellowish-green tufts, or extended beds. It is one of the 

 few mosses that can manage to survive the town atmos- 

 phere, and it may be seen appropriating patches of grass- 

 plots after the grass has been stifled, but it rarely comes 

 to perfection in such situations. 



Dicranella cerYiculata, (Hedw) Schp. {Dicvanum cevviculatum 

 1842. Stansfield Moor. — Herb. Leyl. [Hedw). 



On banks of peat, Langfield Moor. — Herb. Nwl. 

 1888. Todmorden. — T. Stansfield, Lees' Flo. 

 Common on moist banks, especially those of a peaty nature, 

 in open situations. When barren it is easily overlooked
