 Fl. chil. 111. (1847) Ml; Reiche, Fl. Chil. 111. (1902) 99. — »Arborescens, foliis cylin- 

 draceis carnosis, involucro omnino nullo. — Although so very dilTerent in the subslance 

 of ils leaves, tlüs is evidenlly of Ihe same genus as Ihe last, having cqually woody and 

 dichotomous stems, but Ihese are more rugged wilh the membranaceous bases of the 

 fallen leaves. The peduncles are thik and stout, longer Ihan the leaves, one to live at 

 Ihe extremity of the branches. There is no involucre, the heads of flowers are exactly 

 globose, and the paleae are as in the last species {E. hiipleuroides). Fruit exactly 

 that of an Eryngium^ slightly 4-angular, and minutely tuberculated. Styles much 

 shorter than in E. bupleuroides. — If characters be afterwards found to distinguish 

 this section as a genus, the name given by Bertero must be changed, in consequence 

 of a previous Lessonia of Bory de St. Vinc. ; but we ourselves cannot perceive any 

 sufficient difference in the flower or fruit from those of Eryngium. ^
