Wheldon : The North of England Harpidia. 



Group KneiffH Ren. 



(H. aduncum * Kjieiffii Boul. H. adancum Blandowii Sanio ex 



parte). 



Facies not or only indistinctly harpidioid. Usually larger 

 plants than those of the last group. Leaves ordinarily lax, the 

 lower erect or spreading, or slightly secund here and there, 

 the upper much wider and shorter, ovate, acuminate, with a flat 

 point. 



Var. pungens H.Mull. Yellowish green. Stems procumbent, 

 simply divided or slightly ramulose. Leaves erect, subimbricate, 

 the apical ones appressed, forming a cuspidate point, which is 

 straight or slightly curved. Leaves oblong to oval oblong, the 

 lower ones ovato-lanceolate and more spreading. Upper cells 

 long and linear, lower but little dilated. Apparently rare with us. 



9. Pits between Knutsford and Thelford (58), Holt ! 



The only other British specimen I have seen was collected 

 near Stanion (32) by Mr. H. N. Dixon. 



Var. potycarpon Bland. Green. Stems procumbent, much 

 divided, divisions numerous and slender, sometimes fastigiate, 

 not pinnate. Leaves patent or erect, slightly curved at the 

 point, hardly falcate except at the apex of the branches, oval- 

 deltoid or oval-oblong, shortly acuminate, very decurrent, the 

 lower oblong lanceolate, those of the branches often secund. 

 Cells oblong-linear, short, suprabasal lax, quadrate. Fruit 

 apparently rare, but when fructiferous the setae are very 

 numerous. 



9. Near Morecambe (60), Wheldon ! Walton, near Liver- 

 pool (59), Wheldon ! ! 



10. Near Scarborough (62), Wheldon ! Naburn (61), 

 Ingham. 



Var. attenuatum Boul. Rich bright green. Stems very 

 slender, elongated, hardly pinnate, intricate. In drier situations 

 more rigid and depressed, of a less lively green, resembling 

 a miniature form of the preceding. Stem leaves short, deltoid, 

 patent, and recurved at the point, with a short nerve tending 

 to become forked. Auricles of the branch leaves usually almost 

 or quite obsolete. 



The habit of this plant is very distinct, recalling that of 

 Amblystegmm Kochii. Apparently rare. 



9. Burscough (59), Wheldon ! ! A poor state in half dried- 

 up pools. Catterall, near Garstang (60), very fine and typical, 

 A. Wilson ! !
