46 BRITISH HIERACIA. 



below the middle and with 1 or 2 ascending or slightly diverging 

 elongated branches each bearing 2 or 3 heads : lower branch 

 supported by a leaf, upper one (near the top of the stem) sur- 

 passing the original flower. Leaves extremely glaucous or ash- 

 coloured. Eoot-leaves broad, rounded at both extremities, apiculate 

 and nearly entire, or occasionally acute ; narrowed downwards, and 

 more or less dentate in the lower half j rough on both sides, 

 with long coarse scattered bulbous-based white hairs, which 

 become more numerous as they approach the densely pilose 

 margin; or destitute of hairs above; more or less floccose 

 (especially beneath) with stellate down. Original leaves sub- 

 rotund. Petioles usually rather short but sometimes elongated ; 

 dilated at the base, shaggy with villous hairs. Stem-leaves lan- 

 ceolate, very acute, narrowed into a short petiole. Peduncles 

 elongated, frequently rather arcuate, floccose and densely clothed 

 towards the top with black gland-tipped setse. Involucres sub- 

 globose. Thyllaries attenuated upwards, rather acuminate; 

 innermost ones very acute or cuspidate ; outermost frequently 

 more or less obtuse. Morels bright yeUow, perfectly glabrous. 

 Styles yellow, sometimes clothed with faintly livid hairs. 



Possibly this plant may be identical with that described by Pries 

 in his Monograph as " H. murorum pilosissimum," from Ben Bulben 

 in Sligo. Not having specimens from that locality, I am not able to 

 decide with certainty, but cannot regard the above as any variety or 

 form of H. murorum. The brittle stem, extremely glaucous leaves, 

 and slender elongated branches of S. lasiophyTlum, indicate an 

 alliance with H. argenteum. From that species however it differs 

 in being extremely hairy and in having broad and usually obtuse root - 

 leaves and more acute phyUaries. These characters are permanent 

 imder cultivation. 



Pries describes H. lasiophyllum as having " obtuse phyUaries," 

 but recognises the S. lasiophyllum, of Koch's Synopsis, (which 

 is described as having " rather obtuse outer and acute inner 

 phyUaries,") as identical with his H. lasioph/llum. "With the
