 P. 666, line 16, add the species:

WILSONIA R. Br. 



P. 666: 



W. HUMILIS R. Br. 



Should be struck out, not being found in Patagonia. 



The plant now in question was found by me at Puerto Madryn, on the 

 east coast of Patagonia, and has been noted in my representation : 

 "Beitrage zur Flora der Ostkiiste von Patagonien Wissenschaftliche 

 Ergebnisse der schwedischen Exp. nach den Magellanslandern, Bd. Ill, 

 no. 5, p. 255. It was not stated there that the plant coincides with 

 Frankenia cymbifolia Hook., but only that it resembles and may be 

 compared with that species. But the plant turns out to be a true Frank- 

 enia and agrees with Frankenia patagonica Speg. (described in Macl., p. 



579)- D. 



EVOLVULUS L. 

 P. 667 : 



E. INCANUS Pers. 



This species is known also from Argentina and N. Patagonia, Rio 

 Colorado, Rio Negro. 



CALYSTEGIA R. Br. Macl., sub Convolvulus. L., p. p. 



(Calystegia is separated from Convolvulus by having two large bracts 

 rather close to the flower.)
