a tall Eryngmm growing in the pampa and take it, with some hesitation, 

 to be E. agavifolium Gris. They compare the plant also with E. san-

Mexico, S. America on the Cordillera southwards at least to Argentina, 

 S. Fuegia, Falkland Ids., Tasmania, New Zealand. No Patagonian 

 locality is known to me. See Engler und Prantl, die nat. Planzenfam., 

 Ill, 8, p. 163. (D.) (Its occurrence on the Falkland Is. requires its 

 retention here; also in S. Fuegia.) 



O. DAUCOIDES Urb. 



Basal leaves 50-70 cm. long, tripinnate on pinnatisect peduncles, the 

 lower paired; in fruit a half meter long; the upper oppositifoliose ; invo- 

 lucral leaves mostly pinnatifid. Fruiting pedicels 3-5 times as long as 

 the fruits. 



Peru. 



Is often noted as a synonym of the foregoing species ; according to 

 Urban an independent species belonging to the flora of Peru ; by O.
