Wheldon : The North of E?igland Harpidia. 



75 



Cells, upper linear, thin-walled, acute, basal long*, rectangular, 

 incrassate, porose, those of the auricles a little dilated, sub- 

 hexagonal with coloured walls, not distinctly separated from the 

 others. 



9. Ainsdale and Southport (59), Wilson, Marratt, Holt, 

 Whitehead, etc., where it still grows abundantly and occasion- 

 ally fruits.. In the first-named locality an unusually obese form 

 occurs, the stems having a remarkably stout appearance due to 

 the very densely crowded leaves. St. Anne's (60), Wheldon ! !

V. — [Hypnum Capillifolium W T arnst. (H. aduncum var. 

 Schunperi Sanio). A marked feature of this interesting plant is 

 its strongly excurrent nerve. Mr. Dixon refers here some speci- 

 mens found in post-glacial deposits at Mundesley, Norfolk, by 

 Mr. Clement Reid. It should be looked for in the north, as it 

 is a boreal species.] 



VI. — Hypnum uncinatum Hedw. (H. aduncum Linn. 

 Amblystegium aduncum Lindb.). Pale or yellowish green, 

 decumbent or suberect, remotely pinnately branched, branches 

 falcato-incurved at apex. Leaves long, strongly falcate-secund, 

 toothed, from a truncate base broadly lanceolate, piliform subu- 

 late-acuminate, strongly plicate. Decurrent angles of small, 

 not swollen, rectangular, hyaline cells. Perichsetium very 

 prominent, of erect, lanceolate, plicate, leaves, long nerved. 

 Annulus of three rows of cells. Outer peristome teeth with a faint 

 border, transversely striate. Autoicous. Frequent in subalpine 

 places, on walls, tree trunks, and damp ground. Not a marsh 

 plant. I have records of its occurrence in numerous localities 

 in the following vice-counties : — 57 to 60, 62 to 67, 69, 70. 



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

 slender, greener, prostrate, more closely pinnate. Leaves 

 narrower, often contracted above the base, with a long and fine 

 circinate point.
