282 THE JOUKNAL OF BOTANY 



not seem to have been previovisly recorded as a naturalised plant in 

 Britain, and it miglit perhaps be overlooked through confusion with 

 the somewhat similar II. amplexicaule L. 



The salient features of H. inilmonarioides may be stated thus : — 

 Plant phyllopodous, with oblong or oblanceolate radical leaves, 

 5-20 cm. long, with ascending, cusped teeth (especially towards the 

 base), and decurrent on the long, shaggy petioles ; outer leaves obtuse, 

 mucronate, inner acute or shortly acuminate, all clothed on both 

 surfaces with soft, pilose hairs, interspersed, especially above, with 

 fine glandular hairs. Stem 20-40 cm. high, corymbosely branched, 

 sub- 12 headed, pilose below, but becoming thickly glandular above 

 with fine, dark, glandular hairs ; cauline leaves 3-5, the lower lanceolate, 

 broad-based or subamplexicaul, and toothed below, the upper ovate, 

 acuminate, entire, sessile, becoming bract-like, all clothed like the 

 radical leaves. Acladium and branches densely clothed with stellate 

 hairs and long, fine, dark, glandular hairs. Involucre also densely 

 clothed with similar glandular hairs. Ligules pilose-tipped. Styles 

 livid. 



H. pulmonarioides differs from II. amplexicaule in its clear 

 green, non-viscid foliage, with a large proportion of the hairs not 

 glanduliferous ; in its narrower, less amplexicaul cauline leaves, and in 

 the characteristic long, dark, glandular hairs of the inflorescence. Its 

 heads are usually larger than those of H. amplexicaule., than which 

 it is a more conspicuous and beautiful plant. 



I have seen H. pulmonarioides growing in company with H. am- 

 plexicaule and H. lanatum Yill. on the dry rocks below the oratories 

 at Saas-Fee, in the Swiss Valais.

 H. ANGLIC UM Fr. — Although six varieties of this species are 

 described in W. II. Linton's Brifisli Ilieracia, it is probable that 

 other equally se2)arable forms of this polj^morphic plant still remain 

 to be distinguished. The Perthshire hills produce dwarf fovms quite 

 unlike the handsome, large-headed Teesdale plant, with a single 

 cauline leaf, that apparently represents Fries's type. Some of these 

 Scotch specimens are monocephalous and recall the sub-section 

 Alpina genuina, while others bear 2 or more heads, with 2-3 

 recluced cauline leaves. Another Pei-thshire form simulates H. ccesio- 

 murorum Lindeb. in its long-petioled, sharply- toothed leaves, while in 

 parts of Westerness the prevailing form has 'mostly truncate-based 

 foliage. The leaf-clothing of this species is also most variable, inde- 

 pendently of the conditions of environment, for while the foliage is 

 commonly pilose, in some forms it is almost glabrous and in others 

 markedly flocculose.

H. PROXiMUM F. J. Hanb. — A stylose-flowered form wdiich I 

 collected near Keswick in 1903 seems essentially identical with this 

 plant, as represented in Messrs. Linton's set, differing only by its 

 glaucous foliage. Mr. Linton concurs in the name. This is a new 

 locality for II. proximum, Avhich I think has hitherto been recorded 

 only for N. Scotland and N. and E. Ireland. The prevalence of
