BRITISH HIESACU. S5 



Granitio and porphyritio cliffa at an elevation of 2500 to 4000 

 feet ; rare. North-eastern precipices of Lochnagar, associated with 

 H. hilosericeum and H. calenduUflorum. Corrie of Ben-na-bourd, 

 and CaimtoTil, Aberdeenshire. Canloohen Glen, Forfarshire. 



Flowers in 7th and 8th months. 



Plant 6 to 10 inches high, usually with a solitary rather large 

 head. Boot woody but slender, with few fibres. Stem with 

 2 to 4 leaves, numerous setae, and scattered blackish hairs; 

 hoary, especially in the upper part, with dense floccose down ; 

 usually with 1 head, but occasionally with few (2 or 3) heads on 

 simple elongated ascending peduncles. Leaves clothed on both 

 sides with scattered soft white hairs, or nearly glabrous. Eoot- 

 leaves lanceolate, ovate-lanceolate or spathulate, sub-acute or 

 obtuse; outermost broad, rounded; nearly entire or dentate with 

 remote, sometimes acute, glandular teeth; narrowed (usually 

 rather suddenly) into slender or slightly winged petioles. Lower 

 stem-leaves large, linear-lanceolate, acute, nearly or quite entire, 

 narrowed into short or sometimes elongated winged petioles: 

 uppermost small, frequently bract-like. Peduncles densely 

 floccose. Involucres very dark and velvety with rather short 

 dense blackish hairs, interspersed with scattered black-based 

 hoary hairs and numerous gland-tipped setse. Inndi pk^llaries ap- 

 pressed ; outer ones more or less lax ; frequently hoary at the points 

 with dense floccose down. Florets bright yellow, nearly or quite 

 destitute of hairs externally, shortly and slightly pilose at the 

 tips. Styles yellow or rather livid, frequently clothed more or less 

 densely with very minute dark hairs. 



Though closely allied to M. atpinvM, which it strongly resembles 

 in the wild state, S. gradlmtvm appears to dififer permanently from 

 that species, in being of a lighter green and in having a less hairy 

 but more slender setose stem (frequently rather flexuose), larger 

 and more numerous stem-leaves ; a blacker, less shaggy involucre ; 

 more appressed floccose-tipped phyllaries, florets nearly glabrous 

 externally, and styles usually livid. In many poidte it also very
