H. c^'ESTT^M Vr. — A plant collected near Winch Bridge and High 

 Force, Teesdale, in 1<S1JG and 1903, ajjpears to nie to resemble 

 M. lasiophi/Uum \-m\ planifolium F. J. Hanb., but Mr. Linton does 

 not assent to this name, although recognizing that the heads look 

 like those of H. lasioplujUum. Its position must be held doubtful 

 for the present, but it may be pointed out that it substantially coin- 

 cides with Backhouse's description (Mon. j). 5G) of II. cccsiiim. It 

 is believed to be a widely-spread form in Teesdale. 



An entirely different plant, with coarsely dentate leaves, similar 

 to well-authenticated Swedish examples of H. ccesium Fr., was also 

 found on the Durham side of Upper Teesdale in 1903, 



H. FATHJEXSE F. J. Hanb. — Specimens agreeing with this High 

 land hawkweed w^ere found in 1919 in Hesleden Glen, West Yorks. 

 Mr. Linton assents to the naming. 



Sect. VuLfiATA, Sub-sect. Eu-Vulgata. 



H. PixxATiFiDUjr Lonnr. — A very slender form, seemingly refer- 

 able here, with few- flowered panicle and long acladium, occurred 

 sparingly by the Lawers Burn, Loch Tay, in 1907. 



H. scAXicuM Dahlst. — The i^lant sent to the Watson Exchange 

 Club by Mr. Waddell in 1902 from Saintfield, Co. Down, as K. scia- 

 philum, and determined as H. diaplianoides, is identical with 

 H. scanicum, which at that date had not been introduced to the 

 British Flora. It is stated by Ley'(Journ. Bot. xlv. Ill (1907)) to 

 be widely distributed in Wales and the west of England, so that its 

 occurrence in Ireland is not remarkable. 



The sub-umbellate panicle seems to be a marked character of this 

 plant. 



Sect. FoLiosA. 



H. BOREALE Fr. — A number of puzzling forms of this species 

 were growing in company near Bethesda, Carnarvonshire, in 1902. 

 All of them have blackish phyllaries, but while in some the heads 

 are of moderate size, wath livid styles, in others the heads are very 

 large and showy, with bright yellow styles. In some the foliage 

 approaches that of Scotch H. corymbosum, except for the hair- 

 clothing, and in others the leaves are all narrow and subsimilar as in 

 H. rigens Jord. The panicle in nearly every specimen is racemose- 

 corymbose, with rather short, suberect branches. 



The foi-m of H. horeaJe occurring round London appears to 

 be usually the variety Hervieri Arvet-Touvet, which may \)q known 

 not onl}- by its pilose peduncles and grey-green, pilose heads, but 

 by its frequently more laxly-branched panicle.
