HAWKWEEDS. 



JOHN CRYER. 



In an interesting article in the ' Journal of Botany ' for January 

 and February, the Rev. A. Ley, M.A.. dealt with the groups 

 and species ol" the West Yorkshire hawkweeds and their dis 

 tribution as far as they have been ascertained. Much work, 

 hov."e\ er. remains to be done before the list of West Yorkshire 

 hawkweeds and the distribution, are at all adequately known. 

 Grassington and the immediate neighbourhood are fairly rich. 

 in hawkweeds, as the following list of species gathered by the 

 writer will testify : — 



(i ; Hieracium hypochaeroides Gibs., var. saxorum F. J. Hanb. 



(2) 



hritanniciim F. J. Hanb., var. ovale Ley. 



(3' 



silvaticiim Gouan., var. asymmetriciim Ley. 



U; 



var. suhcyaneum W. R. Linton. 



(5) 



cymbi folium Purchas. 



(6) 



duriceps F. J. Hanb. (Type) 



(7) 



scanicum Dahlst. 



(&} 



sciaphilum, L^echtr., var. transiens nov. var. 



{9; 



stnimosum sp. nov. 



(10; 



sparsifoliiim Lindeb., var placerophylhim 





Dahlst. 



^11) 



tridentatum Fr., var. acrifolium Dahlst. 



^12; 



rigidum Hartm., var. calcaricolum F. J. Hanb. 



On 



comparing the above with Mr. Ley's list it will be noticed 



that numbers g, 11, and 12, are not recorded for the West 

 Riding of Yorkshire, and numbers i, 2, 6, 7 and 8 are not 

 recorded for Wharfedale, and the rest are not recorded for 

 Grassington and the immediate district. 



H. sarcophylliim Stenstr. is recorded b}-^ Mr. Ley for Lang- 

 clifi. Ribblesdale. The writer gathered a fine specimen at 

 Malham, August 2nd, igo6, also a specimen of H. hritannictim- 

 F. J. Hanb.. var ovale, Ley, and one of H. cerebridens Dahlst., 

 in the neighbourhood of Malham. Fine specimens of H. 

 scanicum Dahlst. were found growing near Leeds in September 

 of last 3'ear, along with H. cacuminatum Dahlst. Mr. Ley 

 says of this latter, 'rare in Britain.' 



H. Gothic urn Fr., described by Mr. Ley as ' not common,' 

 was found by the writer in fair abundance near Shipley, August 

 1907.
