 often girt with a short crenulate ring. DISTBIB. N. temp, and Arctic 

 regions ; species about 150. ETYM. <e/>o, a haivk. 



In the following attempt to classify the British Hieracia, I have been guided 

 by Mr. Baker. I believe that there are no characters whereby the 9 forms, 

 from alpinum to borcale inclusive, can be more than approximately denned ; 

 of these 9 Bentham makes 4, Nyman 21, and Backhouse, followed by 

 Babington (having regard to a considerable amount of constancy under 

 cultivation), makes 30, of which only 16 bear the same name in Nyman. 

 Variable as the genus is, the sequence of its forms is so natural as to have 

 been recognised by all botanists. This sequence represents to a considerable 

 extent the spread of the forms in altitude and area in the British Isles. 



SECTION 1. Piloselloi'dea. Rootstock stoloniferous. Stem scape- 

 like. Invol. scales irregularly imbricate. Ligules glabrous. Fruit minute, 

 furrowed, crowned with a crenate disk ; pappus-hairs slender, equal. 



1. H. Pilosel'la, L. ; stolons long, scape leafless, heads solitary, invol. 

 bracts acute, ligules pale yellow, styles yellow. Mouse-ear Hawkweed. 



Banks, wall- tops, &c., N. to Orkney ; ascends to 2,400 ft. in Yorks. ; Ireland ; 

 Channel Islands ; fl. May-Aug. Villous with long soft hairs. Stolons 

 creeping. Leaves 2-4 in., oblong-lanceolate or obovate-spathulate, stellately 

 downy beneath. Scapes 2-10 in., with 1-3 leaves or 0. Heads f-1 in. 

 diam. ; involucre subcampanulate and top of scape stellately downy and 

 with glandular hairs ; ligule often striped with brown on the back. Fruit 

 JQ in., dark. DISTRIB. Europe, N. Africa, N. and W. Asia. 



H. Peleteria'num, Mer. (H. pUosis'simum, Fries), is a more densely silky form, 

 with stolons shorter, heads larger.
