THE PHANEROGAMS OF THE JUAN FERNANDEZ ISLANDS

The insular plant is certainly identical with L. Harioti Franch. Miss. sci. 

 Cap Horn V. 344, of which I have seen type material from Herb. Mus. d'hist. 

 nat. in Paris. Another question is if this is different from L. nudicaulis (Comm.) 

 P. Dus. (fig. 27 c— e, 28 a— b). L. Harioti (fig. 28 c— e) is larger and more 

 slender, the leaves less crowded, more distinctly dentate and always pubescent. 

 The involucral scales are larger, c. 4 mm, rarely exceeding 3 mm in nudicaulis. 

 The flowers are slightly larger, but the achenes look very much the same in 

 both. There may be as much reason to regard L. Harioti as a form of the 

 other, in which case the name var. gracilis (Alboff) should be used. Alboff, 

 Contr. Fl. Terre de Feu II. 27 placed his variety under L. hirsuta Less. It has

nothing to do with this. L. hirsuta (fig. 27 a— b, 28 h— m) is known by the 

 shape of the leaves, that are larger and more deeply crenate, and especially 

 by the long beak of the achene, which also has strong lateral nerves absent in 

 the others, as seen from fig. 28 h— m; these nerves are also visible in the figure of 

 POEPPIG and ENDLICHER, Nov. gen. et spec, plant. II tab. 26, though not mentioned 

 in the descriptions. I have figured one achene of the original material (fig. 28 h). 

 L. Harioti has been mistaken for hirsuta on account of the hairy leaves, also 

 by the writer (Zur Flora des Feuerlandes, Wiss. Erg. Schwed. Siidpolar-Exp. 

 IV: 1 : probably all the specimens quoted belong to L. Harioti). Franchet 

 regarded his species as »bien differente de L. Commersonii (= nudicaulis) et 

 voisine de L. Forsteri (=pumila)»: comp. fig. 28 n— o. Still, it is much nearer 

 to the former. L. pumila differs in the shape of the leaves and bracts and also
