2£ BRITISH HIERA.CIA. 



lax, especially the small outer ones. Florets bright yellow ; hairy 

 externally, and more or less densely pilose at the tips. Styles 

 livid, clothed with minute fuliginous hairs. 



Var. tenellum, resembles the typical form, but has more slender 

 and less elongated stems (4 to 8 in.) ; entire, or slightly dentate 

 (rarely coarsely dentate) leaves, and yellow styles. 



A plant wliich. occurs above Glen Caness and on the cliffs above 

 Loch Ceanndin, which has stems 9 to 12 inches long, large rather 

 ovate obtuse very coarsely toothed root-leaves, lanceolate stem- 

 leaves, and very large heads with broader phyllaries and yellow 

 styles, is probably an extreme form of this variety, but requires 

 further examination. 



"When growing in the crevices of hard micaceous rock (as in Glen 

 Piadh, Glen Dole, &c.) its leaves are toothed, but when on crumbling 

 or shaly mica slate (as on the cliffs around Loch Brandy and Loch 

 Wbarral) it produces entire leaves. In the wild state it rarely (?) 

 branches, though I have met with a few specimens both of the 

 incised and entire-leaved forms, bearing 2 to 4 flowers on the 

 same stem. 



Under cultivation this plant flowers twice in the same season (in 

 the 6th and 8th months). At the first flowering the heads are 

 usually produced upon simple (unbranched) stems, while at the 

 second flowering (one to two months later) they are borne upon 

 robust branched stems sometimes Ig feet high, with 4 to 6 heads on 

 elongated peduncles. The var. tenellum (which seems to be the 

 " form" that H. eximium assumes on the granite) when cultivated 

 becomes nearly as robust and branching as the typical form, but 

 always retains its yellow styles. 



Among a large range of specimens of the " Alpinum growp" from 

 Norway, Switzerland and the Tyrol, I do not find a single example 

 of jff. eximiwm, and consequently conclude that it is rare, or possibly 

 not existing in those countries.
