FURTHER NOTES ON HIERACIA. 181 



Hieracium nigrescens Willd. var. commutatum Lindeb. — From 

 the eastern slopes of Cairn Toul, and probably other mountains in 

 the Cairngorms. 



H. norvegicum Fr. var. confertum Lindeb. — From Glen Lyon, 

 collected by Mr. W. F. Miller in 1888, and so named by Dr. 

 Lindeberg from two stations. The Kev. E. S. Marshall collected 

 the same plant in 1890 by a burn descending from Ben More 

 (Perth), about two miles east of Crianlarich. 



H. diaphanum Fr. f. — A plant collected by Mr. J. C. Melvill at 



Prestwich, near Manchester, was so named by Dr. Lindeberg. The 



Lancashire specimen agrees well with No. 85, Hierac. Scand. 

 Exsicc * 



H. diaphanum Fr. var. stenolepis Lindeb. — Collected by the 

 Rev. Augustin Ley in August, 1890, from the Northern Cliff of the 

 Brecon Beacons ; also from Craig Gledsian, both localities being in 

 Breconshire. A very distinct form. 



H. cesio-murorum Lindeb. — First determined as a British plant 

 from a specimen collected by the Eev. E. F. Linton at the Linn of 

 Quoich, near Braemar, in 1889, and subsequently collected at 

 several stations in Perthshire both by Dr. F. Buchanan White and 

 the Rev. E. S. Marshall. Our specimens agree admirably with the 



type No. 59, Hierac. Scand. Exsicc. 



H. protractum Lindeb. — Collected during successive seasons by 

 Mr. W. H. Beeby in several localities in Shetland ; the specimens 

 agree well with the type No. 40, Hierac. Scand. Exsicc. A very 

 distinct and handsome species, apparently confined to the Shetlands, 

 as far as Britain is concerned. 



H. murorum L. pt. var. sagittatum Lindeb. — Gathered from 

 four distinct localities in Perthshire by Dr. F. Buchanan White, 

 Mr. Marshall, and myself. Specimens have been seen and so 



Hierac 



agree well with 



H. onosmoides Fr. — First determined as British from speci- 

 mens gathered at Braemar, where, however, the flowers seldom or 

 never develop properly, the ligules remaining curled up and of a 

 greenish colour. The same may be said of specimens gathered in 

 Uig,^ Skye, by the Rev. W. R. Linton in 1888. I gathered my first 

 specimens on rocks in the Clunie, in the middle of the village at 

 Braemar, also by the Linns of Dee, in 1886, but, regarding them as 

 abnormal, I did little with them until the Rev. E. F. Linton sent me 

 similar specimens from the Sluggan in 1889. Some of these I sent 

 to Dr. Lindeberg, who at once named them "H. onosmoides verum, 

 v. paucifolius." It was not, however, till July, 1890, when the Rev! 

 E. S. Marshall and I met with a luxuriant and well-developed 

 Hieracium on the railway-bank at Tain, in East Ross, growing in 

 great quantity, that really good specimens of this plant were found, 

 and these were so luxuriant (some over four feet high) that they were 



* I purposely omit quoting the paragraph on this plant appearing in the 

 Eev. E. F. Linton's paper in the Journal of Botany, 1891, vol. xxix. p. 272, as I 

 feel some doubt about the identity of the Prestwich and Longridge plants, and 

 have not time to clear the question up before this paper goes to press.
