 posed to be a subspecies of Oreomyrrhis andicola. 



P. 639 : 



APIUM L. 



Concerning the species of this genus I shall venture on only a few 



remarks. D. 



A. AMMI (Jacq.) Urb. 



(Described in Macl., p. 640, sub syn. Apium leptophyllum (DC.) F. Muell.) 

 N. B. Jacquin was the first who described this specie.?. 



A. CHILENSE Hook, et Arn. 



Macloskie's statement about this species having been found at Coy Inlet 

 is erroneous and refers to Apitim graveolens L. (Dusen). Why not 

 Apium graveolens L.? (Skottsberg.) 



P. 640: 



A. PROSTRATUM Labill. 



Not being found either in Patagonia or in Magellan, this species is to be 

 eliminated.

May be omitted ; not known from our district.
