256 PATAGONIAN EXPEDITIONS : BOTANY. 



dentata, carnosula, c. i.o cm. longa, lamina 3.0-3.5 mm. lata et 3.0-4.0 

 mm. longa, recurvata, in petiolum sat longe decurrente, inconspicue ner- 

 vata ; capitula terminalia, solitaria, exinvolucrata, foliis caulinis supremis 

 dense cincta ; cetera ignota. 



S. Patagonia, Rio F6siles, on strong soils in the mountains (1,000- 

 1,600 m.). 



Perennial ; stem low, simple or few-branched ; the lower leaves remote, 

 small, upwards gradually greater and denser, imbricate, the uppermost 

 rosulate, spathulate, glabrous, long-petiolate, entire or rarely more or less 

 distinctly few-dentate, fleshy, recurvate, indistinctly nerved, the limb long- 

 attenuate basewards; heads terminal, solitary, without involucre, but 

 closely surrounded by the uppermost leaves. 



This species stands nearest to Moschopsis leyboldi Phil., which differs 

 from the present in longer, elongate-spathulate, acute leaves. 



As to its habit, this species reminds us of Acicarpha rosulata N. E. 

 Brown. It is, however, less robust, having more rounded leaves, being 

 entire or only laterally, never terminally, serrated. Whether Acicarpha 

 rosulata, by reason of the absence of one involucre, ought rather to be 

 placed in the genus Moschopsis may at present be left undecided.
