A NEW BEITISH HIERAC1UM. 



By the Rev. Edward S. Marshall, M.A., F.L.S. 



H. anfraetiforme, n. sp.— Stem 9-20 in. high, simple or (in 

 luxuriant specimens) branching from below the middle, rigid, 

 fistular, glabrous below, becoming floccose upwards, and bearing a 

 very few stalked glands. Branches rigid, ascending, Boot-stock 

 woody, with rather numerous, stoutish fibres. Bo»t -leaves firm in 

 texture, glabrous and bright green above with prominent pellucid 

 veins, sometimes slightly glaucous-tinted, their margins with a few 

 weak patent hairs, pale beneath, with scattered hairs ; from linear- 

 lanceolate to lanceolate or oblanceolate in outline, acute or apicu- 

 late. Blade 2-4 in. long, very gradually tapering into a long 

 (1~2| in.), slender, hairy petiole, strongly dentate or sharply 

 incised. Teeth pointing forwards, gland-tipped, narrowly tri- 

 angular or linear, the longest (lowest) sometimes exceeding £in. in 

 length, from 5 to 10 on either side. Stew-leaf one (rarely two on 

 strong plants), stalked, very deeply cut into linear segments or but 

 slightly toothed, reduced to a linear bract in small specimens. 

 Peduncles £-1 \ in., erect or ascending, somewhat floccose, darkened 

 in their upper part by numerous stalked glands. Heads 1-4, when 

 the stem is simple ; when branched, the branches bear from 1-4 

 heads apiece. Involucre cylindric in bud, campanulate in flower ; 

 phyllaries very dark with black-based hairs and stalked glands, 

 woolly -tipped with white down before the flowers open, with a 

 scarious border, obtuse, gradually narrowing from their base. 

 Flowers golden-yellow, about l£in. across when fully expanded ; tip 

 of the ligules ciliate. Styles rather livid with minute dark hairs. 

 Acheves chestnut-coloured. 



Habitat: Rocky subalpine streamlets of the Western Breadal- 

 banes, on granite and mica-slate, from 1400 to 1800 ft. 



I first met with this species in June, 1888, by a burn descend- 

 ing from Clach Leathad, Glen Etive, Argyle, and was much struck 

 by its distinct look. The follow ng summer, I again found it in 

 Corrie Ardran, near Crianlarich, Perthshire. Mr. F. J. Hanbury 

 r visited both stations in my company, and we agreed in thinking 

 it different from any form hitherto known in this country. H. 

 anfractani Fr., as represented in Lindeberg's Scandinavian sets, 

 appeared to resemble it very closely, and specimens were sent to 

 Dr. Lind^berg under that name. About those from Glen Etive he 

 wrote: — "Primo obtutu videtur forma scaposa H. anfracti, at 

 involucra et lata anthela demonstrant, eandem esse aliam novam 



formam"; while he reported on the Perthshire ones thus: 



u Species nova, a ceteris bene distincta videtur.' J 



Dr. Buchanan White has collected the same plant on the 

 Argyle side of Ben Laoigh ; and, although I have forgotten the 

 exact date of his discovery, I believe that it somewhat precedes my 

 own. Mr. Hanbury also informs me that it was found last summer 

 by Dr. W. A. Shoolbred, near the road between Glen Lyon and 

 Tyndrum.
