21. H. sfrictum Fries (straight-hranched IL); stem leafy 

 ri^id, leaves oblong-lanceolate narrowed at the base and sub- 

 amplexicaul, peduncles clothed with stellate down and the 

 blackish involucres sprinkled with seta3 and haii^s, scales rather 

 irregularly imbricated inner ones obtuse, ligules ciliated, achenes 

 blackish-brown slightly scabrous. 



Scotland, in mountain-glens. Ochills and Braidalbane mountains, 

 Forfarshire. I/.. 7,8. — '^ Hairs on the underside of the leaves 

 bulbous-based." — Bah. Fries says that the branches are leafless, but in 

 specimens from Dr. Dewar, similar to those examined by Fries, they 

 are furnished with small leaves or bracteas. Peduncles frequently 

 with a few short black hairs or setas mixed with the down. Involucres 

 with more copious black hairs and seta3 than could, be inferred from 

 the character given by Fries: scales appressed, imbricated; the 

 margins with white down, particularly in bud, 



22. H. tridentdtum Fries {straight-scaled shruhhy H,) ; stem 

 leafy rigid or flexuose slightly hairy panicled at the top, lower 

 leaves ovate-lanceolate slightly stalked few-toothed about the 

 middle, upper narrower and smaller passing gradually into 

 bracteas, peduncles elongated erecto-patent and the involucres 

 stellately downy with few black hairs and sometimes seta?, 

 invol. in flower ovate at the base after flowering ventricose 

 and constricted in the middle, scales dark green bluntish or 

 acute paler at the margin outer ones lax inner narrowest, 

 ligules glabrous at the apex, styles yellowish. 



Woods and thickets, probably frequent, l^. 7, 8, — The above 

 character is obtained from Mr. Baker's notes made on the plant as found 

 in Teesdale : he adds that it is '^ intimately allied to H. sylvaticum .-" 

 sometimes there is a rosette of leaves at the base of the stem when 

 the plant is in flower. 



23. H. rigidiim Hartm. (rigid- stemmed i7.) ; green, stem 

 rigid leafy panicled at the top, leaves lanceolate or linear-lan- 

 ceolate all nearly similar in shape few^toothed about the middle 

 lower ones stalked, upper nearly sessile, involucres after flower- 

 ing narrowed upwards and not constricted in the middle with 

 fugacious stellate down sprinkled with black hairs and set^, 

 scales lanceolate bluntish uniformly green blackish by drying, 

 ligules glabrous at the apex, achenes blackish-brown slightly 

 scabrous. 



Mountainous districts. IJL. 7, 8. — With this species we ar^ 

 scarcely acquainted, and have therefore taken our character almost 

 entirely from Fries, who compares it with the last, from which it 

 would appear to differ by the involucre, Mr. Baker informs us that 

 when Teesdale specimens of H. corymhosum were sent to Fries, he 

 labelled them '\H, rigidum.'' 



24. H. corymbosiim Fries (corymbose JT.) ; *' stem rigid nearly 

 glabrous densely leafy paniculato-corymbose at the top, leaves
