BRITISH HIERACIA. 57 



nearly destitute of glands. Innermost pliyllaries usually very 

 attenuate and acute. Florets bright yellow. Btijles faintly livid. 



The reaemblance of this species, in some of its forms especially, to 

 H. pallidum, H. lasiophyllum, and H. murorum, is considerable. It 

 may be distinguished from ^e first of these by its smaller stem-leaf, 

 sub-obtuse phyllaries, perfectly glabrous florets, and rather livid 

 styles ; also by the absence of the long rigid coarse hairs which 

 usually frini^e the root-leaves of that species. From all the forms 

 of H. lasiophi/Uum it diflFers in having more acute root-leaves, and 

 in the absence of the very coarse hairs which dlothe both surfaces of 

 the leaves of that species more or less densely : also in having livid 

 styles. Lastly, it may be distinguished from H. murorum by its 

 coriaceous, darker green root-leaves, much reduced stem-leaf nar- 

 rowed to a nearly or quite sessile base, straighter and longer 

 peduncles, larger and fewer heads, more floccose but less setose 

 involucres, obtuse or sub-obtuse outer and very attenuate pointed 

 innermost pliyllaries. 



Fries describes H. ccesium as having " one or few leaves," which 

 character is maintained in specimens from the vicinity of Christiania 

 given to me as the true S. ccesium by Professor Blytt. Some of 

 these, indeed most of them, have a large stalked stem-leaf, and seem 

 to be very closely allied to H. murorum., if indeed they are distinct 

 from that species. This circumstance makes me doubt the identity 

 of the plant above described (which has a much reduced stem-leaf 

 or none at all) with the H. casium, Fries' Symb. p. 112. 



The species of which the Giggleswiok plant may be regarded as 

 typical, agrees well with the description oi " H. ccesium" in Grenier 

 and Godron's Flore de France, p. 371. On the Clova and Braemar 

 mountains a plant not unfrequently occurs with more rigid less 

 hairy broader-based root-leaves, a rather large stem-leaf, and less 

 attenuate inner phyllaries, which is no doubt the plant described by 

 Fries as H. ccesium ; indeed specimens of it transmitted to Fries 

 are acknowledged by him to be that species. The Giggleswick 

 plant may eventually prove distinct from this, but as yet I have not 

 found characters sufGLoiently marked to warrant their separation,
