 Hymenophyllum bivalve, Hook, and Grev., Ic. Fil., t. 83. 



Juan Fernandez. Philippi; Reed. 



This species inhabits Chili, New Zealand, the Auckland Islands, Tasmania, South 

 Africa, and Mauritius. 



Hymenophylluni reniforme, Hook. 



Hymenophyllum reniforme, Hook., Sp. Fil., i. p. 110, t. 38 ; Hook, and Bak., Synopsis FiL, p. 59; 

 Gay, Fl. ChiL, vi. p. 531 ; Philippi in Bot. Zeit., 1856, p. 631 (errore uni forme). 



Juan Fernandez. Gay ; Philippi. 



Of this very distinct species, the only specimens in Kew Herbarium are from Northern 

 Peru and the Andes of Quito in Ecuador, hence there is some doubt about its being a native 

 of Juan Fernandez. Philippi does not state whether he had seen specimens, or whether he 

 copied Gay. 



Hymenophyllum subtilissimum, Kunze. 



Hymenophyllum subtilissimum, Kunze, Anal. Pteridogr., p. 50, et Farmkrauter, p. 187; Hook, and

 Hymenophyllum ferrugineum, Colla in Mem. Accad. Sc. Torino, xxxix. p. 30. 



Juan Fernandez. — On rocks and roots of trees in the shady woods of the higher 

 mountains — Bertero; Peed; Philippi; Moseley ; Downton. 



Extratropical South America, and New Zealand. 



In Hooker's Handbook of the Flora of New Zealand this is retained as a variety of 

 Hymenophyllv/m ceruginosum, Carm., a Tristan da Cunha plant, which is certainly very 

 near it ; but we have here followed the Synopsis Filicum. Plate XXXVIII. is a good 

 representation of the Tristan da Cunha plant. 



The inscription on Bertero's label with this species corresponds exactly to that cited by 

 Colla under his ILjmenopIujllum ferrugineum, and as the description agrees as well, we 

 have no hesitation in classing it with this.
