360 ON A VARIETY OF HIERACIUM CESIUM. 



Finally, in April, 1879, just before I left Rasen, Mr. W. Allen 

 and myself were "moss-trooping" across some swampy uncultivated 

 ground at Woodhill, near Rasen, where are several old clay- 

 bottomed pools, — on Kimmeridge clay, not red sand, — when my 

 companion drew my attention to a dwarf, strikingly golden tinged 

 moss growing with undoubted B. nitabulum upon a damp clayey 

 grassy ridge close by one of the jdooIs. I was led to examine it 

 carefully, when of course it turned out to be the palustral form or 

 variety Mildeanwn, Schimp. Here was a further confirmation of 

 the accuracy of Renauld's restriction as to site of growth in the 

 variety. The Woodhill plant was not fruiting ; but I have seen 

 B. Mildeanum from Southport (H. Boswell), and Hayle sands, 

 Cornwall (W. Curnow). 



An old record (1838) of William Wilson's names Helk's Wood, 

 Ingleton, in West Yorkshire, as a station for H. salebroswn 

 (Raines's 'Flora of Yorkshire,' 1840), but there I have, so far, 

 only been able to find Brachytliccium (jlareosum — which, by-the-bj^e, 

 is H. salehrosum of Hooker and Taylor, but not of Hoffmeister. 

 To my eyes H. salehrosum, Hofi^m., is quite as likely to be passed- 

 by as H. (/lareosum as is H. imtahuluw ; esj)ecially is it like 

 a rank and barren state of H. (/lareosum, which is common on 

 damp shady banks in old limestone quarries near Wetherby. 



Of importance as extending the range of H. salehrosum, Hoffm., 

 much beyond the limits already alluded to, must be stated the fact 

 that Mr. Mitten is said (Hobkirk, ' Synopsis,' p. 148) to have 

 found it in Sussex. Has Mr. G. Davies seen this last ? The 

 authority is too good for it to be a likely error. 



It is quite needless for me to attempt to add anything to 

 Mr. Spruce's account of the differences between B. salehrosum and 

 allied species ; yet, let me say, lest it should be thought, in my 

 effort to confirm Mr. Spruce, I appreciate differences only after 

 others point them out, that in the Y^orkshire ' Naturalist ' for 

 February, 1878, I placed on record my discovery of the true 

 B. salehrosum in Lincolnshire ; and that I there drew attention to 

 the very differences Mr. Spruce alludes to in 1879, and in words 

 not so very dissimilar pointed out the hue of green as one readily 

 api)reciable, noting the silkier more plumose tufts, and more 

 gradually-acuminate leaves of B. salehrosum as compared with 

 B. rutahulum, and the fact that when once carefully observed, side 

 by side, they can be distinguished at a glance by the ' colour-test ' 

 alone. 



ON A VARIETY OF HIERACIUM CESIUM FROM 

 THE GREAT ORMES HEAD. 

 By J. G. Baker, F.R.S. 

 There is a Hieracium on the Great Ormes Head of which I 

 have known for many years, but have never had the opportunity of 

 gathering or seeing alive under cultivation, of which the remem- 

 brance has just been revived in my mind by receiving a specimen 

 to be named collected there in last July by the Rev. W. H. Painter.
