180 FURTHER NOTES ON HIERACIA. 



little tour among the beautiful mountains in South Donegal. Mr. 



Hart's thorough familiarity with this country and the continuance 

 of fair weather made this trip a most successful one — agreeably 

 ended by a day or two's rest at my companion's picturesque home on 

 the western shore of Loch Swilly. The Mourne Mountains in Co. 

 Down formed the next district to be examined. Here I was 

 fortunate in having as a guide Mr. S. A. Stewart, whose botanical 

 acquaintance with the N.E. of Ireland is known to all. The rocky 

 bed of the Shimna river, in Tollymore Park, yielded several 

 interesting species. Hilltown then became our head- quarters, 

 whence several fruitful excursions were made, giving me the 

 opportunity of studying in situ several forms which had been the 

 subject of much previous correspondence. A few days near Bangor, 

 in the company of Mr. J. E. Griffith, and then three more among 

 the Carnarvonshire hills with the Rev. Augustin Ley, completed my 

 personal explorations. 



To particularise the large amount of local work accomplished by 

 many valued correspondents in nearly every part of Great Britain 

 and Ireland during the same period would be out of place here, and 

 unduly lengthen my notes. I cannot, however, refrain from ex- 

 pressing my great indebtedness to my frequent companion and 

 constant correspondent, the Rev. E. S. Marshall ; to the Rev. 

 Augustin Ley, for the expeditions he has made to nearly every part 

 of Wales ; to Mr. W. H. Beeby, for a very fine set of Shetland 

 Hieracia ; to the Revs. E. F. and W. R. Linton, for good work done 

 in Dumfries, Forfar, and Aberdeen ; to the Rev. H. E. Fox, for 

 several valuable parcels of fresh Hieracia from the Lake District ; 

 to Dr. Buchanan White, for a very large collection of Perthshire 

 specimens got together by himself and friends in connection with 

 his forthcoming Flora of that county; to Mr. G. C. Druce, for 

 specimens from Ross, Inverness, Banff, &c. ; to Messrs. Hart, 

 Levinge, More, Praeger, Scully, and Stewart, for Irish specimens; 

 and to the Revs. W. H. Purchas and W. H. Painter, Messrs. 

 H. and J. Groves, J. C. Melvill (to whom I am also indebted for 

 some useful suggestions in nomenclature) and R. Kidston ; to the 

 Misses Thompson, and others. 



One result of all this kind help has been to increase my own 

 collection of the British Hieracia to the somewhat unwieldy bulk of 

 about 4000 sheets, exclusive of the Backhouse and Boswell herbaria, 

 which are kept separate, and thus unavoidably to hinder and delay 

 my work, though I trust the ultimate outcome may be to make it 

 more thorough and comprehensive in its character than could 

 otherwise have have been possible. Once more I have to acknow- 

 ledge the invaluable assistance of Dr. C. J. Lindeberg in looking 

 through and maldug critical suggestions on some very large parcels 

 transmitted to him ; indeed, but few British forms remain which 

 have not now passed through his hands. 



Before proceeding to describe and name those forms which 

 I believe to be new, it may be best to mention the following species 

 and varieties, recognised on the Continent, that have been added 

 to the British list since the appearance of my last notes in 1889 ; a 

 few already published, others now made known for the first time.
