FURTHER NOTES ON HIERACIA. 867 



appear to me to belong to this species. The specimens are old, 

 discoloured, and badly dried, and the locality should be searched 

 anew. Under cultivation the styles of the Dovedale plants become 

 pure yellow, and thus exactly approximate to the form occurring in 



the Settle district. 



H. britannicum var. vagense, n. var. — As a variety of this 

 species a very remarkable plant discovered by the Rev. Augustin 

 Ley, on rocks by the Wye in Errwood, may be suitably described. 

 It extends for a considerable distance on both sides of the river in 

 Brecon and Radnor, whence Mr. Ley first sent me specimens, 

 gathered on the 16th of June, 1887. The following year I received 

 through the Botanical Exchange Club, a specimen, differing but 

 little from the Wye plant, from Craig Breidden, also collected by 

 Mr. Ley, on the 13th of June, 1887. This had evidently been sent 

 to Mr. Backhouse mixed with some H, *" 



made a pencil note,—" Probably the same as the other ; yet it 

 looks more like pallidum crinhjerum than they do." The plant 

 appears to me to agree well with a type specimen in the Kew her- 

 barium of H. pallidum Biv. var. Pseudo-catsium Schur. Its affinities, 

 however, are much more with H. britannicum than with H. pallidum. 

 A single sheet was sent to Dr. Lindeberg, who dismissed it as a 

 " forma monstrosa Hieracii murorum." As it is a form occurring 

 in two counties over a considerable length of the Wye, and is also 

 found on Craig Breidden, Montgomery, and which when cultivated 

 and grown from seed maintains all its distinctive characters, it can 

 hardly be disposed of thus. Professor Babington wrote concerning 

 specimens submitted to him : " I have what seems to be the same 

 as this from Cairntoul, gathered and named nitidum by Backhouse, 

 except that the styles are differently coloured. Backhouse I see 

 does not venture on a name for yours. The curiously overtopping 

 phyllaries in the heads of the Wye plant deserve attention." It is 

 impossible, for many reasons, to place this plant under H. nitidum, 

 as would be apparent to anyone seeing it when fresh, whilst the 

 extreme glaucousness and prominent venation of the leaves, shape 

 and clothing of the involucre, as well as its fair agreement in 

 general characters, closely unite it to H. britannicum, from which, 

 however, it may be readily distinguished by its narrower, more 

 deeply and acutely toothed leaves, pure yellow styles, and slenderer 



habit. . ,, ,., . 



H. Sommerfelth Lindeb. var. tactum, n. var.— Another striking 



form from the mountains around Kingshouse, Argyleshire. Closely 

 resembling H. Sommerfeltii in foliage and general habit ; the invo- 

 lucre is so conspicuously different as to raise a doubt whether it 

 may be possible in the long run to treat it has a mere variety of this 

 species From the limited locality from which it is yet known, and 

 from the paucity of material in my possession, I prefer to do so for 

 the present. The plant is of too marked a character to be passed 

 over and it is well that attention be at once directed to it, in order 

 that' others may endeavour to extend the knowledge of its range, 

 and gain additional information respecting its habits. Mr. Mar- 

 sh all and I first found it on Cla^k Leathead, and in Fionn Glen,
