COMPOSITE. 193 



Var. a, genuinum. 



Radical leaves generally attenuated towards the base, sub- 

 acute, dentate ; petioles slightly woolly ; stem-leaf very small and 

 sessile, or none. Elorets bright-yellow. 



Var. 3, ohtusifolium. 



H. obtusifolium, Back. Mon. Hier. p. 58. 



Pirst radical leaves rounded at both extremities, nearly or quite 

 entire ; petioles very short and shaggy ; stem-leaf rather large, 

 shortly stalked. Plorets pale-yellow. 



On rocks chiefly in mountainous districts, but apparently much 

 less abundant than H. murorum. The specimens in Mr. H. C. 

 Watson's Herbarium and my own are from near Settle and 

 Hawnby, Yorkshire ; Xirkstone, Northumberland ; Braemar, Aber- 

 deenshire ; and Durness, Sutherland. Mr. Backhouse considers 

 that a plant from Hoy Hill, Orkney, belongs to this species ; but 

 the specimens are too immature to enable us with certainty to 

 extend the range so far North. 



England, Scotland, Ireland. Perennial. Summer 

 and Autumn. 



Stem 9 to 18 inches high. Leaves thicker in texture, more 

 glaucous, more attenuated into the petiole than in H. murorum, 

 which it very much resembles. Anthodes fewer and considerably 

 larger, with more stellate down and white hairs, and fewer gland- 

 tipped hairs than in the ordinary state of H. murorum. The 

 pericline is much broader and not cylindrical when in fruit. 

 The softer hairs, reduced stem-leaves, whiter phyllaries, and yellow 

 styles, distinguish it from H. pallidum and nigrescens. Eries says 

 of H. caesium, " Eolia radicalia * * * subtus stellato-floccosa ;" 

 but the British plant has no stellate down on the under side of 

 the leaves. Is it the same as Eries's plant ? 



H. obtusifolium I have never seen : Professor Babington refers 



it to H. caesium. ^ . ^ ^ ,
