TOPOGRAPHICAL NOTES ON HIERACIUM 235 



of H. dovrense, Fr., and then to be H. onosmoides, Fr., was 

 eventually submitted to M. Arvet-Touvet, who forthwith 

 rejected the Skye-Braemar-Moffat plant as not typical, and 

 claimed this Tain plant as exactly his H. bnglossoides. 



H. sifoaticum, Gouan, aggr. Prof. Trail (p. 96) says, 

 "All except 73, 103." This statement of wide distribution 

 is perhaps founded on a note in "British Hieracia," ambiguous 

 because too condensed, " This is the H. murorum, var. ft 

 silvatmim, of Linnaeus, etc." This note gives the impression 

 that the restricted H. silvaticum, Gouan, includes all the 

 numerous forms that we have associated with H. murorum, 

 auct. angl., whereas in "British Hieracia" it only includes a 

 few varieties which are scarce and very local. Var. micra- 

 cladiuin, Dahlst, is the most frequent, and may perhaps be 

 on record for nine Scottish vice-counties. Var. phacotrichum 

 should be phceotrichum, and I agree with W. R. Linton in 

 doubting very strongly any British record of it. 



H. custalis, Linton. Omit 92 ; I have withdrawn this 

 plant as not identical. 



H. duriceps, F. J. Hanbury. The counties from which 

 this "has been recorded" must all be struck out except 98, 

 1 08, and 112, the ones referred to in " Brit. Hier." The case 

 is an instructive one. H. duriceps was founded on specimens 

 gathered at Bettyhill by Mr. Hanbury in 1884. In the 

 next two or three seasons several gatherings were made of 

 a very similar looking plant, and recorded as H. duriceps. 

 Most of these gatherings proved to be H. micracladiuni, 

 Dahlst., and in course of time came to be so recorded. 

 These deduct largely from the records of H. duriceps, and 

 account for most if not all of the erroneous ones. 



H. truncation, Lindeb. To the best of my knowledge 

 i i 2 is the only genuine record. 



H. stictophyllmn, Dahlst. ( = H. spars if oliu-in bot. angl.). 

 I can confirm 72 (Moffat frequently, and Sanquhar), and 73 ; 

 also I 10 (Stornoway) ; and can add 108 ; but can find no 

 data for 86, 99, 102, 105. It is, however, a very distinct 

 species, not easily mistaken. Omit 97 ; this record belongs 

 to H. sparsifolhuii, Lindeb. 



//. strictum, Fr. I have specimens from 96. 



H. corymbosuin, Fr., var. salicifolium, Lindeb. A plant
