Ingham : Mosses and Hepatics of the Buckden District. 311 



Another peat moss, Sphagnum recurvum, occurs on the top 

 of the Pike, as also S. aciitifolium var. viride, both on the Pike 

 and on Birk's Fell. 



11. — Buckden to Oughtershaw. 



By the roadside, among- grass, was a larg-e mass of Hypmini 

 stellatiun forma gracilis Boulay. On the dry limestone Tn'chos- 

 omum crispulum and the brown tufts of Barhtila recurvifolia 

 were frequent. Other mosses were Dichodontium pellucidiim 

 forma, Orthotrichum anomalum var. saxatile, O. cupiilatnm, 

 Barhnln ruhella, JVeisia rupestris var. compacta , and Barbula 

 spadicea. 



The hepatics were Scapania aspera, the dominant one in dry 

 places, Jungermania cordifolia , Plagiocliit^i Dillenii, and Cepha- 

 lozia Jtnitans. 



III. — Birk's Fell and Wood. 



In the wood larg^e masses of Bartramia CEderi covered with 

 capsules were prominent. Wehera crnda, in fruit, and the 

 hepatic Jungermania Lyoni, in fruit, grew intermixed. The 

 pale, dull green, flat patches of the hepatic Metzgeria puhescens 

 grow here in shade. 



In Step Gill, up the fell, \s Amhlystegiiim filicimun var. Vallis- 

 clausce, and on dry stone Weisia viridula var. densifolia , but 

 the rarest moss of this g-ill is P/iilonotis adpressa, which I think 

 is an addition to the Yorkshire flora. This moss I recorded 

 from Burnhope Burn in Durham. The source of Step Gill is 

 filled with Brachythecium rivulare var. cataractarum, with Nardia 

 compressa and Chiloscyphus polyanthos, two largfe hepatics. 



Dichodontium flavescens, with very pellucid cells, and a curious 

 form of D. pellucidum also g-row by the g-ill. 



IV. — Deepdale. 



The interesting- mosses of this dale are Weisia curvirostris 

 var. scabra, Dicranum BonJeaniw3.r. juniperifolium, Trichostomnm 

 crispulum var. nigro-viride , and a flat prostrate form of Plagio- 

 t/iecium pulchellum. 



The hepatics, too, are interesting, the chief being- Lejeunea 

 serpyllifolia var. heterophylla, Lophozia Muelleri, a larg^e form 

 near var. subcompressa (Limpr.), and a smaller form with the 

 mature leaves like L. bantrieiisis, Nardia compressa, Junger- 

 7nania ventricosa, Scapania purpurea , and on a ledg"e of rock on 

 the return by Cray Gill, a very fine growth of Reboulia hemi- 

 sphcerica covered with capsules.
