MACLOSKIE : REVISION OF FLORA PATAGONICA. 135 



S. Patagonia, near mouth of Rio Gallegos; on steppe by Richmond 

 farm near Sta. Cruz Emporium. 



P. 432: Delete Brassica magellanica Pers.; its correct name is Sisym- 

 brium magellanicum (Pers.) Hook, fil., on p. 431. 



Add Macl., p. 432 : 



SINAPIS ALBA Linn. White Mustard. 



Erect, with pinnatifid leaves, having large terminal lobe; fruit con- 

 stricted between the seeds; beak long and flat. Terminal raceme of 

 yellow flowers. 



Falkland Is. 



P. 432 : 



BRASSICA L. 



B. MAGELLANICA Pers. 



Should be deleted, being identical with Sisymbrium magellanicum 

 Hook. fil. 



RORIPA Scop. (Nasturtium R. Br.). 



R. PUBESCENS PINNATISECTA (Ok.) 



Should be transferred to the genus Lepidium as L. bonariense L., var. 

 pinnatisectum Ok. 



CARDAMINE L. Macl., p. 435. 



The corrections are here so numerous that it seems to me necessary to 

 give a quite new explanation of the species. Before doing so, I remark 

 that the following are to be deleted : 



The plants referred to : C. amara L., C. antiscorbutica Banks & Sol., 

 C. hirsuta L. and its var. magellanica (Phil.), C. strictula Steud., and per- 

 haps C. ciliata Phil., all belong to Cardamine glacialis (Forst.) Hook. f. 



C. corymbosa Hook, f., not in this region. 



C. pygmcea Dus. belongs really to genus Nasturtium (Roripa); but spe- 

 cifically is scarcely determinable. 



C. rostrata Gris. var. dichondroides Speg. is identical with C. integri- 

 folia Phil. 



The following species should also probably be deleted : 



C. ciliata Phil. not mentioned in Gilg & Muschler's Synopsis of S. 

 American Crucifercz; perhaps identical with C. glacialis.
