H. boreale Fr. The form far most common in Herefordshire 

 seems to fall under that called Eu-sabaudum, of Zahn, characterized 

 by having its stem very hairy from base to heads, including the 

 phyllaries themselves. A plant answering to H. obliquum of 

 Jordan in being less hairy in all its parts, and having smaller 

 lanceolate leaves, occurs on the Red Daren, Hatterel Hills. Another 

 form, which appears to be the var. eminens of Jordan, with glabre- 

 scent stems and heads, the leaves ovate, broader, and coarsely 

 toothed, occurs in several places in woods. Bolston Wood, 1888 ; 

 Haugh Wood, 1891. This form is common in Wales.
