MACLOSKIE: REVISION OF FLORA PATAGONICA. 133 



Add: 

 THLASPI ALPESTRE L. var. GRACILE (Phil.) Gilg & Muschler. (Synonym.) 



Glabrous, simple; radical leaves rosulate, bright green, oblong, atten- 

 uate to a petiole, obsoletely toothed ; cauline leaves auricled, semiam- 

 plexicaul, distant. Raceme lax ; silicic obovate, long-attenuate at base , 

 its apex nearly truncate, as long as the pedicel. Style one third as long. 



Central Chili, in the Cordillera; eastern slopes of the Cordillera of 

 Valdivia ; S. Patagonia, in the mountains near Lago Argentine. 



Note by Gilg & Muschler (Engler's Bot. Jahrb., Bd. 42, p. 453). This 

 variety is much more robust than the type. The specimens of Thlapsi 

 gracile Phil., collected by Mr. Prichard in the district of Lago Argentino 

 (see Journal of Botany, Vol. 42, p. 329), are, however, much more slender 

 than the type. 



P. 429 : Thlaspi glaucophyllum Barn. (No. 2) is only a var. of T. 

 magellanictim. Thus Thlaspi magellaniciim Com. var. glaucophyllum 

 (Barn.) with synonym. T. glaucophyllum Barn. 



P. 429 (No. 3) : The authority of Thlaspi magellanicum is Commerson 

 (1806). (Persoon gave the same name in 1807.) 



Add Macl., p. 429: 



T. ANDICOLA Hook. & Arn. 



Note. Reiche in his Flora de Chile, 1. 169, gives T. andicola as an 

 independent species. Gilg & Muschler are of the same opinion. Skotts- 

 berg (Engler's Bot. Jahrb., Bd. 42, p. 452) regards T. andicola as iden- 

 tical with T. magellanicum. (See Skottsberg, zur Flora des Feuerlandes, 

 p. 18; Wissenschaftliche Ergebnisse der Schwedischen Siidpolarexpedi- 

 tion 1901-1903, 4 Lief. 4.) Dusen regards this opinion as well-founded, 

 and consequently accepts Skottsberg's arrangement. 



Common in the Fuegian and Patagonian steppes, especially in the 

 remote southern and western sections ; also in the mountains of Western 

 Patagonia, as in the upper valley of Rio Aysen, about 1,200 m. at 

 Arroyo Scheuen. 



Sisymbrium sagittatum Hook. & Arn. and Sophia sagittata Hook. & 

 Arn. infra, p. 449, are identical with each other, and both synonyms of 

 Thlaspi magellanicum Comm.
