Wheldon : The North of England Harpidia. 



accordingly describe the plant here rather than in the group 

 obsoletum. Many of the British forms hitherto referred here 

 must be placed under var. atlanticum Ren. 



9. Tatham Moor, Cotshaw Fell, and Hawthornthwaite Fell 

 (60), A. Wilson ! ! Mallowdale Fell (60), Wheldon and A. 

 Wilson ! ! 



Forma condensata Sanio. Stems short and tufts compact. 

 Appears to be merely a starved state of dried-up marshes. 



8. Crowden Brook, Edale (57), W. R. Linton. 



9. White Moss, Hindburn (60), Wheldon and A. Wilson ! ! 

 Var. atlanticum Ren. (Journ. Bot., 1901). Approaching the 



var. Jeanbernati, but differing in its glossy green colour, its 

 leaves wider, oval, more suddenly narrowed to a shorter acumen 

 and usually densely chlorophyllose. Nerve wider at base (58-64 \l 

 as against 46-48 ju). Basal cells wider and shorter, gradually 

 longer above, chlorophyllose. For a fuller description see Journ. 

 Bot, 1901, p. 277, 'New Varieties of Hypnum fluitans,' by 

 H. N. Dixon. 



8. Kinder, near Hayfield, and Redcar Brook, above Dove 

 (57), W. R. Linton ! 



9. River Wyre, Wyresdale (60), Albert Wilson ! ! Pendle 

 Hill (59), Wheldon ! ! Calder Valley, above Oakenclough (60), 

 A. Wilson ! Longridge Fell (60), Wheldon ! Black side of 

 Tarnbrook Fell, Hare Apple Tree Moss, and Abbeystead Fell 

 (60), A. Wilson and J. A. Wheldon. 



10. Near Halifax, a large submerged form (63), Crossland ! 

 Forma gracilis Ren. More slender, leaves smaller, but of 



similar form to the type. - Nerve narrower, but the cells remain 

 wider than in var. Jecuibernati.

It is probable that this variety, which has already been found 

 in France (Lachenaud) and North America (Dr. Grout), will be 

 found not only widely spread, but variable, and the var. Holleri 

 may have to be subordinated to it. They require further study. 



Var. elatum Ren. et Arnell. More laxly tufted than the 

 last, loosely intricate and floating. Stems more robust, and 

 more branched, the branches again pinnately divided. Leaves 

 larger, more crowded, somewhat falcate, oblong or oblong 

 lanceolate, truncate at the base, rather suddenly contracted to 

 a rather wide and short acumen, denticulate. Nerve narrow, 

 reaching three-quarters, or shorter. Cells long and narrow, 

 auricles ill defined, their cells sometimes a little swollen. This 

 approaches very closely to the var. Jeanbernati, but is taller,
