H. TENERIFOLIA (Remy). 



The next species, H. tenuifolia (Hook. & Arn.) Gris. is very probably 

 identical with H. tenerifolia, as supposed by Skottsberg, Flor. Feuerland, 

 p. 37. Both marked by him as having achenes rostrate. 



H. USHUAI/E Skottsberg. 



A perennial with thick rootstock sending up numerous stems. Leaves 

 rosulate, obovate-lanceolate to lanceolate, narrowing to a petiole, 10-17 

 cm. long, i cm. more or less broad, acutish, repand, tooth remotely 

 repand-toothed, glabrous. Scape leafless, with one head, about 12 cm. 

 long, scape thick and tomentose upwards, and tomentose, or rufous. 

 Involucre 12 mm. high, 10 mm. wide. Outer scales ovate-lanceolate, 

 4-5 mm. long, hispid-pilose ; inner scales longer ; innermost longest and 

 thinnest. Pales of receptacle very narrow, filiform, tipped, scarious. 

 Flowers, including achenes, about 12 mm. long; achenes (young only seen) 

 with rostrum 7 mm.; pappus 7-8 mm., whitish. 



S. Fuegia, in alpine regions above Ushuaia, swamps in the Bolax- 

 heaths, about 700 m. 



TARAXACUM Wiggers.

T. IBARI Phil. 



The description published in Anal. Univ. Chil., Tom. LXXXVII, p. 

 324, is too brief and incomplete to give a clear conception of the system- 

 atic rank of this species. There is, however, in the diagnosis nothing 

 inconsistent with the presumption of the identity of T. ibari with T. 

 magellanicum Comm. ; Sch. Bip. Philippi, actually, has expressed the 

 supposition of these two species being identical. The question cannot 

 be decided without examination of type-specimens. 



This species is dubious.
