 and call it H. arenaria Gaud. without hesitation. 



In several fleras, so in Reiche's Flora de Chile, Dusen's 

 länd., we find H. arenaria Gaud. as a citizen of Patagonia 

 statement seems to be incorrect and is due to the fact, that H.

 Herbaria of Upsala and Stockholm thus named, belong to H

H. arenaria: 

 Leaves few, variable, the oldest ± entire, 

 spathulate, sinuate and irregularly 

 denticulate, the others (or even all) 

 obovate-lanceolate, long petiolate, irre- 

 gularly pinnatifid with ± large end- 

 lobe, setulose along the margins, 

 slightly hispid on both surfaces, 4—6 

 (—8) X 0,5— 1,6(— 2) cm. 



Peduncles simple, aphyllous or with 1 — 2 

 involucral scales just below the head, 

 hispidulous below, ± arachnoideous at 

 the apex, 1 — 6 cm. high, on fruiting 

 specimens 10 — 15 cm. 



Head narrow campanulate, gradually 

 narrowed to the base, 1,5 — 2 cm. long, 

 0,5—0,6 cm. broad in the middle. 



Involucral scales dark brown or nearly 

 black, outer 0,4 — 0,7 cm., linear, gra- 

 dually narrowed to the tip, obtuse, with 

 coarse, black hairs along the middle, 

 and with ± arachnoideous, finally sub- 

 glabrous margins, inner l,o — 1,6 cm., 

 linear, acutate, almost glabrous and 

 with scariose borders. 



Flowers with tube 4 mm., tongue 5x1,5 

 mm., bright yellow. 



Style little exserted, 2 mm. longer than 

 the corolla tube; its branches filiform, 

 1 mm. long. 



Achene fusiform, furrowed longitudinally 

 and regularly striated across, 7,5 mm. 



H. coronopifolia : 



Leaves numerous, filiform-linear, on long 

 petioles, ending in a short, pungent, 

 cartilagineous mucro, with thick, not 

 setulose margins, especially in the 

 lower half with a few, short (to 0,5 cm.) 

 mucronate lobes, as young ± arach- 

 noideous on both sides, låter ± gla- 

 brous, 4 — 7 cm. long with rhachis of 

 0,1—0,3 cm. 



Peduncles simple, aphyllous or with 2 — 3 

 subulate, tomentose leaves in the upper 

 half, ± arachnoideous, upwards with 

 more dense, whitish wool, 2,6 — 10 cm. 

 high, on fruiting specimens 12 — 15 cm. 



Head ± broad calyculate, suddenly 

 contracted at the base, 1,5 cm. long, 

 0,7 — 1,0 cm. broad in the middle. 



Involucral scales blackish, outer 0,5 — 0,6 

 cm., linear triangulate, with dark wool 

 at the base, arachnoideous with per- 

 sistent tomentum, inner linear, l,o— 

 1,2 cm. long, obtusate, arachnoideous, 

 with scariose borders. 



Flowers with tube 7 mm., tongue 8x2 — 



2,6 mm., påle yellow. 

 Style mucli exserted, 8 mm. longer than 



the corolla tube; its branches 0,3 mm. 



thick, 4 — 4,5 mm. long.
