168 FURTHER NOTES ON HIERACIA. 



almost orange, pilose externally, and more or less so behind the 

 tips. Styles fuliginous. Involucre urceolate-campanulate, very 

 dark. Phyllaries dark green, with very numerous short black- 

 based hairs and setse. Stem fistular, sparsely floccose. Leaves 

 glabrous above, with scattered white hairs below and on the 

 margins. Two years' cultivation by Mr. Marshall and myself show 

 the distinctive characters to be well maintained, and, in a light 

 Surrey soil, strengthened. 



H. callistophyllum. n. sp. — This, like the last, appears to be 

 confined to the mountains of Argyleshire and West Perth. Mr. 

 Marshall and I gathered it in July, 1889, from no less than five 

 distinct localities around Kingshouse, from all of which I have it in 

 cultivation; and last year Mr. Marshall sent me a single plant 

 from the cliffs of Stob Garbh. Though probably referable to the 

 Xitjrescentes, the plant differs conspicuously from its allies in the 

 remarkable and beautiful form of the radical leaves (this suggested 

 the name), in the large size to which it often attains, and in its 

 short, rather blunt, and grey-tipped phyllaries. Stem from 1 to 2 ft. 

 high, often much branched, and bearing from 1 to 18 large showy 

 heads ; radical leaves of extraordinary and very characteristic form, 

 the outer ones being almost balloon- shaped, the apex forming a 

 complete semicircle, devoid of teeth, and sometimes even emargi- 

 nate ; whilst the base, armed with coarse outward-pointing teeth, 

 gradually tapers into a long petiole ; the inner leaves much more 

 acute and sharply-toothed, all of medium texture, and very prone 

 to turn purple. There is usually one sessile cauline leaf, also very 

 acute and sharply-toothed. Heads from 1^ to 2 in. across. 

 Ligules bright medium yellow, faintly pilose-tipped when young, 

 then quite glabrous. Styles very slightly livid or almost pure 

 yellow. Phyllaries dark green, rather blunt, bearing a tuft of long 

 white hairs at the tips, clothed throughout with white black-based 

 hairs and few setae, sparingly floccose at the base, densely so as the 

 peduncle is reached. This is a most conspicuous species in culti- 

 vation, often forming a dense clump from 3 to 4 ft. high, separating 



n at a glance from any form of IL niyrescens or H. suhmurorum, to both 

 of which Dr. Lindeberg has at times thought it to bear some affinity. 

 H. anglicum Fr.* var. jaculifolium, n. var. — A plant apparently 

 confined to the English Lake District. Whilst closely allied to 

 H. angUcum, it differs remarkably from any other variety of that 

 species in having the cauline leaf borne on a long straight petiole, 

 and not sessile, both radical and cauline leaves often javelin-shaped, 

 the ligules never properly developed, but alwavs curled up (con- 

 stituting what continental botanists would call a "forma styfosa"). 

 Ihe heads rather more numerous, and peduncles shorter, &c. It 

 was hrst sent to me in August, 1881, by Mr. W. 13. Waterfall, from 

 (rhyll iu Kirk Fell, Cumberland." The .specimen was immature,
