Dr. Dablstedt remarked on specimens sent him, " H. sordichim 

 does not belong to any of our forms, and not to H. Sclimicltii 

 group, which has yellow styles ; this one has dark styles." 



First gathered by us in 1890 at Craigmichen Scar, near Moffat, 

 Dumfriesshire, and grown at Bournemouth and Shirley ; then in 

 large quantity in 1907 by the Revs. W. R. Linton and E. S. Mar- 

 shall (see Watson B. E. C. Report, 1910, pp. 148, 149) from the 

 same locality. 



Allied to H. Schmicltii by its foliage and to H. lasiopliyllum 

 by the look and clothing of the involucre, it differs from the 

 former in its inflorescence generally and its spot-leaved foliage, 

 from tlie latter by its broader subglabrate leaves, and from both 

 by its compact habit and livid style. The latter feature suggested 

 the name. 



H. dentifex, sp. nov. Stem about 18 in., subglabrous, thinly 

 hairy below ; leaves green, hairy beneath, dentate (sharply in 

 cultivation), long-petioled, earlier broadly ovate with broad sub- 

 cordate or truncate base, later ovate-oblong to oblong-lanceolate ; 

 stem-leaf or at most a laciniate bract. Panicle few-flowered ; 

 peduncles floccose, glands numerous, strong, very unequal ; phyl- 

 laries lightly floccose chiefly on the margins, strongly glandular, 

 with few hairs, scarcely senescent (the primary head nearly as 

 hairy as it is glandular) ; ligule tip glabrous ; style yellow. 



H. DENTIFEX, sp. uov. Caulis sparsim vel raro pilosus, superne 

 floccosus. Folia rosularia viridia, longe petiolata, supra glabres- 

 centia, subtus pilosa, exteriora late ovata basi subcordata-truncata, 

 interiora ovato-oblonga — oblongo-lanceolata, inaequaliter et grosse 

 dentata acuta ; folium caulinum velparvum laciniatum. Anthela 

 oligocephala, pedicellis floccosis, glandulis densis fortibus et in- 

 aequalibus instructis. Involucra basi rotundi-ovata. Squamae 

 angustae dorso levius marginibus densius floccosae, sparsim pilis 

 densius glandulis sat validis obsitae, vix comatae. Ligulae ad 

 apicem glabrae. Stylus luteus. 



This was sent by W. R. Linton to Dr. Dablstedt as H. Schmidtii 

 form ?, and he replied that it was " not H. Schmidtii, but an allied 

 form." It differs from the aggregate H. Schmidtii in having green 

 not glaucous leaves, shorter and less acuminate, longer petioles, 

 more glandular and less pilose peduncles, floccose and much more 

 glandular heads with stronger and more unequal glands. It is 

 best placed next after H. Schmidtii.

H. SoMMEEFELTii Lindeb. var. setosum ex herb. W. R. Linton,
