COMPOSITE. 173 



This plant comes very near H. melanoceplialum, but the stem- 

 leaves are more developed, the lower ones generally nearly equal 

 in size to the radical ones ; the pericline is smaller, and blacker 

 from a greater number of the hairs being destitute of white points. 

 The florets are more glabrous on the back, and the styles duller 

 yellow. The plant is also of a lighter green.

Stem usually simple, very sparingly clothed with stellate down 

 and black gland-tipped hairs, intermixed with long black-based 

 simple hairs. Radical leaves obovate or oblanceolate, " abruptly " 

 (Backhouse) or gradually attenuated into the petiole, obtuse ; the 

 inner ones narrower and sub-acute ; all denticulate or serrate- 

 dentate or entire, more rarely coarsely toothed, glabrous or nearly 

 so above, generally hairy beneath and on the margins ; stem- 

 leaves few, small, rarely 2 to 4 and large ; the lower ones oblan- 

 ceolate, attenuated into a j)etiole ; the upper one, or all, strap- 

 shaped-lanceolate, sessile. Anthodes solitary or rarely 2 to 4 in a 

 corymb, globose in bud. Pericline hemispherical, rounded at the 

 base. Phyllaries narrow, very acute, olive-black, densely clothed 

 with rather short black-based and black hairs, interspersed with 

 short black gland-tipped ones. Plorets sub-glabrous, externally 

 glabrous, or slightly pilose at the tips. Styles bright-yellow. 

 Plant green or glaucous. 



On granite and felspar, at an elevation of 2,500 to 4,500 feet. 



I have gathered it only on Cairntowl, but it occurs also on Ben- 



na-main, Ben-na-muic-dhui, and the north side of Little Craigindal, 



Braemar.

This plant comes very near H. gracilentum ; but the anthodes 

 are considerably larger, the phyllaries much narrower, longer, more 

 acute, and not so black ; the buds are more globose. I cannot find 

 any tangible difi'erence in the shape of the leaves, judging from 

 my specimens, which are authenticated by Mr. Backhouse.
