H RARUM R. Br. Macl., p. 130. 



The occurrence of his species in S. America appears to be somewhat 

 doubtful. H. rarum 3 omitted in The Reports of the French Cape Horn 

 Expedition, and has ben found neither by Skottsberg, nor by Spegazzini 

 and Dus6n. The S.American plant hitherto stated to belong to H. 

 rarum represents, acording to Christiansen, some forms of 21, Hymeno- 

 phyllum cuneatum Ke, Anal, pterid., p. 50, which consequently should 

 replace H. rarum R. Jr.
