FURTHER NOTES ON HJEBACIA. 259 



Phyllaries all rather obtuse, floccose, and very sparingly clothed 

 with setae and short black-based hairs, the outer very small, rather 

 lax, and extending into the peduncle, Ligules glabrous. Styles 

 slightly livid on the under surface. 



A plant collected by Dr. White in 1875, from Glen Tilt, Perth, 

 may, I think, be referred to this species ; but the only specimen I 

 have is immature, and not well dried. A further search therefore 

 in this locality should be made. Specimens sent to the Botanical 

 Exchange Club by Mr. T. A. Cotton, who collected them last 

 autumn in Upper Wharfedale, Yorks, are perhaps best placed to a 

 form of this species, despite their almost glabrous involucre and 

 weaker habit. While calling attention to these probable British 

 localities, it is to the Irish specimens from Down and Donegal that 

 I give the name, and from which both the description and drawing 

 have been taken. 



H. murorum L. pt., var. pulcherrimum, n. var. — A singularly 

 beautiful variety, first collected and pointed out to me by Miss 

 Thompson, with whom I subsequently gathered it at Catterick 

 Force, near Settle. Here, on the inaccessible rocks of the deep 

 gorge, and constantly moistened by the spray rising from the water- 

 fall below, grows a fine colony of it, whence a good series was 

 secured for drying and figuring. My next acquaintance with the 

 plant was made on the Carnarvonshire Hills, prior to my visit to 

 which Mr. J. E. Griffith asked me to carefully observe a very 

 beautiful form of H. murorum, which was scarce, and grew on 

 ledges at a good elevation. With the Rev. Augustin Ley, I found 

 it on the Carnedd Dafydd Cliffs, near Bethesda. Though the 

 specimens were fine, they were by no means abundant, and in all 

 probability we failed in finding its head-quarters in the district. 

 Whilst united to the more ordinary forms of H. murorum in average 

 size and general arrangement of the foliage and inflorescence, it is 

 conspicuous by its beautiful close panicle of deep golden-yellow 

 flowers, very black velvety setose involucre, slender almost straight 

 peduncles, and markedly pilose-tipped ligules. The leaves, both 

 radical and cauline, are lanceolate to ovate, more entire than in the 

 type, and narrowed at the base into a shaggy petiole. 



Before passing from H. murorum, I may here mention that the 

 variety, sarcophyllum Stenstr., published as a subspecies under H. 

 silvaticum (L.) Almq.,* has been found by Dr. White on the banks 

 of the Tay, at Murthly Castle ; by the Messrs. Linton at Black's 

 Hope, Moffat, Dumfries ; and by Miss Thompson, Mr. Whitwell and 

 myself about Settle, and at the base of Ingleboro' ; and by the Rev. 

 H. E. Fox at Kirk Fell, Ennerdale. Another variety, H. micra- 

 Indium Dahlst. (also published under H. silvaticum), has been 

 found by Colonel J. S. Stirling in a corrie at the Head of Balglass, 



* In Scandinavia many of the authors reverse the sense in which we use the 

 names H. murorum and H. sy Iv at ic urn, though the sheet in the Linnean Her- 

 barium clearly supports, I think, our view as to what plants Linnaeus intended 

 to be designated by the name viurorum; but, like many questions of nomen- 

 clature, it is somewhat complicated, and for the purposes of this paper may be 



left for the moment,
