truncate at the base. Phyllaries acute, dark-olive, with rather 

 long and stiff white hairs with black bases ; outer ones lax. 

 Plorets hairy externally and at the tips. Styles livid, yellow in 

 var. /3. Plant green. 



Var. a, genuimmi. 



H. villosum, Sm. Eng. Bot. No. 2379. 



Stem elongated, 6 to 15 inches high. Radical leaves elliptical- 

 oblanceolate, generally toothed. Styles livid. 



Var. 3, tenellum. Back. 



Stem 4 to 8 inches high, more slender than in var. a. Hadical 

 leaves narrower, usually entire. Pericline smaller, of a darker colour. 

 Styles yellow. 



On cliffs at an elevation of 2,000 to 3,000 feet. Not uncommon 

 on the mica-slate rocks of the Clova district and head of Glen 

 Callater, rare on the granite, where it occurs sparingly on Loch- 

 na-gar, Ben-na-bourd, and Little Craigindal, Aberdeenshire, and 

 Ben Alder, Inverness-shire ; var. (3 on granitic mountains of the 

 Cairngorum range. I have gathered it on Cairntowl and Loch- 

 na-gar, and Mr. Backhouse on cliffs of Ben-na-main, above Loch 

 Awn, Ben-na-bourd and Little Craigindal (Braemar), Caness, and 

 cliffs above Loch Ceanndin (?), Porfarshire. 



Scotland. Perennial. Autumn. 



Extremely like H. calenduliflorum, with which Dr. Walker 

 Arnott is probably right in combining it. The leaves, how- 

 ever, are longer, narrower, and more acute ; the teeth are gene- 

 rally smaller, and when large, point forward and not outward, as 

 in H. calenduliflorum. The anthodes are considerably smaller ; the 

 pericline generally about \ inch long, scarcely so dark in colour, 

 and with the phyllaries not so numerous. Mr. Backhouse states 

 that the leaves are entire when growing on crumbling rock and 

 toothed when on hard rock. 



Var. 3 is considered a distinct species by Professor Grenier. 



Grey-headed Saickweed.
