3. var. densifolia (Philippi). 
Syn. Hymenophyllum densifolium Philippi, Linnaea 29: 
108, 1857, ex descriptione. 
Size and habit of f. typica; pinne very close, imbricated, 
boat-shaped, short, falcate, bluntly rounded at the apex, 
slightly hairy on the midrib beneath; sori terminal on the 
upper pinne; indusium deeply two-lipped with obscurely

Islas Guaitecas: Melinca, 1. 7. 1908.

Colonial, nr. 446, 23. 8. 1908. — Masafuera, forest, 
27.8. 1908. 
This is another new addition to the flora of Juan Fer- 
nandez; although the specimens from both islands are sterile 
I do not hesitate in referring them to this variety, which, 
however, only with diffieulty and good will can be distin- 
guished from f. typica. Compared with the specimens from 
Falkland Islands the samples from Juan Fernandez are of a 
fresh yellowish-green colour and of a very folded appearance.
