though he learnt Dr. Dahlsteclt's opinion (" seems to be very 

 closely related to H. expalliclwn Norrl. andiJ. j^hilanthrax Stenstr. 

 from Sweden "). It may therefore be placed in our list somewhere 

 between these two. I am able now to add some further localities 

 by uniting with this some other gatherings of mine from Scotland, 

 a gathering of Eevs. W. E. Linton and E. S. Marshall from Kinnel 

 Burn, near Moffat, and with rather less assurance one of Eev. 

 A. Ley's Yorkshire gatherings of H. j^hilanthrax, which seems to 

 be not that plant but my new species. The distribution then is: — 

 64 Buckden, Mid-w^est Yorks, A. Ley. 72 Dumfries, W. E. Linton. 

 88 Meall na Saone, Mid-Perth, E. F. and W. E. Linton. 90 By 

 the Blackwater Eiver, Loch Brandy and Glen Doll, Clova, Forfar. 

 A Glen Shee plant, 89, perhaps belongs here, having the foliage 

 though not the more glandular inflorescence of H. orithales. 



H. HOLOPHYLLUM W. E. Linton var. dentulum, nov. var. 

 Leaves dull green, purpurascent, more rounded or even truncate 

 at the base than the type, inner ovate-oblong, somewhat dentate 

 in the lower half (strongly dentate in cultivation) ; stem-leaf ovate- 

 acuminate more or less dentate. Peduncles floccose, with several 

 glands and hairs ; phyllaries darker green than the type with 

 more numerous glands and hairs. Style livid. 



Hestleden Glen ; Cowside Beck, Arncliffe ; Kettlewell ; Dent 

 Dale, W. Yorks. 



This variety is more distinct than appears from comparing the 

 description here given with that of the type in Brit. Hier. p. 50. 

 The latter was expanded so as to include the Arncliffe and Kettle- 

 well forms. The leaves of the type have no well-developed teeth, 

 the heads are green not blackish-green, the styles are pure yellow 

 by the original description, and yellowish though not always 

 a clear yellow, "becoming dusky with age" (Journ. Bot. 1890, 

 376). 



The material for this variety was collected by the Eevs. A. Ley 

 and W. E. Linton, and points of difference were noted, but no 

 MS. name occurs in their notes. 



H. EiGiDUM Hartm. var. eubefactum, nov. var. ex herb. W. E. 

 Linton. Stem somewhat scabrid, pilose, rubescent. - Leaves firm, 

 rather sparse, lanceolate, narrowed to the petiole in the lower or 

 to a sessile base in the upper, only the uppermost rather broad- 

 based ; dentate with few teeth, ultimately rubescent ; phyllaries 

 efloccose, with fairly numerous unequal glands, hairs few or 0, 

 Style livid. 



This variety comes nearest to var. Friesii of our forms, and 

 has " not been seen among the Scandinavian Rigida " {teste 

 Dahlstedt). 



This variety has been found in the following localities : — 

 Derbyshire : Chapel-en-le-Frith ; along Bar Brook, above Baslow ; 

 a plant from near Bamford, with more yellow-livid styles, seems 

 to be the same variety. Eadnorshire : railway banks near Ehayader.
