226 Dr. Smith's Observations respecting 



bourhood of the places mentioned in the Flora Anglica, and so 

 I believe have many other botanists, without finding any thing 

 which could be referred to these species. I was therefore obliged 

 to content myself with avowedly copying Hudson, subjoining 

 whatever I could ascertain as illustrative of these species ; and in 

 doing this I have been thought by a learned friend to have taken 

 the one for the other. From this supposed error I now wish to ex- 

 culpate myself; — at the same time the following observations may 

 clear up the history of these plants, hitherto almost equally ob- 

 scure to the botanists of every country in Europe. 



It is necessary to premise that these two species are as distinct 

 as possible from each other. What I understand as H. dubium 

 is strikingly related to Pilosella, from which it differs chiefly in 

 having more than one flower, generally 3 or 4, on a stalk, and 

 hence probably obtained the name of dubium. Its leaves are 

 short, obovate, blunt, much fringed at the base; its flowers le- 

 mon-coloured both above and below ; its calyx woolly, sprinkled 

 with scattered, very short, black hairs. This is H. Auricula of 

 Fl. Dan. t. 1111. 



My H. Auricula, the dubium of Fl. Dan. t. 1044, is generally 

 a taller and larger plant, with fewer and smaller scyons from the 

 root, longer and perfectly acute leaves, which are less copiously 

 and regularly fringed ; its flowers smaller, more numerous, of 

 the full yellow or orange-colour usual in the genus ; the calyx 

 clothed with very black long dense hairs. 



I now proceed to a chronological history of each. 



Hieracium dubium is first mentioned by Linnaeus in the 

 first edition of his Flora Suecica, No. 634, under the specific cha- 

 racter of "foliis integris ovato-oblongis, stolone repente, scapo nudo 

 multifloro." In the first edition of Species Flantarum it occurs 

 under the same definition, except the advantageous alteration
