ADDITIONAL SPECIES, ETC. 3C1 



including H. cerinthoides of the Manual, edition tliird ; 

 the localities for the latter having likely been formerly 

 reported as if those of H. Lawsoni. 



H. OREADES, Fries. — Apparently not known to British 

 botanists of the present day. " Gordale Scar, near Mal- 

 ham, Yorkshire, Dill." 



H. SAXiFRAGUM, Fries. — Stated in the Manual to have 

 been found on Caii-ntoul, Aberdeenshire ; Glen Dole, 

 Clova, Forfarshire ; Teesdale, York or Durham. 



H. ATRATUM, Fries. — Said to have been found in the 

 Highlands of Scotland, and on Helvellyn, Westmoreland. 

 Partially included imder the H. nigrescens (Willd.) of the 

 second volume ; but while it still remains difficult to trace 

 a clear line or limit between the three, I believe that there 

 is a thii'd species somewhat intermediate in general ap- 

 pearance between H. nigrescens and H. murorum of that 

 former volume. 



H. MURDRUM, Linn. — According to the Manual, found 

 on Cheddar clilfs, Somerset ; about Llyn Ogwen, Caer- 

 narvonshire ; Ben Wyvis, Ross-shire. It is not the H. 

 murorum treated in the second volume ; but either is 

 unknown to me, or was perhaps included under the 

 species of the second volume. 



H. CESIUM, Fries. — This would seem to correspond 

 almost precisely with H. murorum of the second volume 

 and of most English botanists and collectors. The 

 vax"iety "hypochoeridoides," for which Mr. Babington in- 

 dicates the locality of Settle only, occurs in various 

 counties of Scotland and England, but has been usually 

 labelled or reported under the misnomers of " maculatum " 

 (by Mr. Lees, &c.) and " pulmonarium " (by Mr. Gardiner, 

 &c.). The H. maculatum (Sm.) may be the H. affine (Swtz;..) 

 of the Flore de la Lou'e. But one of two specimens, given 

 to me thus labelled by Mr. Lloyd, looks very like H.
