Fournier identifies the Amsterdam plant with Hymenophyllum capillare, Desv. 

 {Hymenophyllum lineare, Swartz), while Baker, in Kew Herbarium, has written it up as 

 Hymenophyllum obtusum. These species and the Hymenophyllum ceruginosum of the 

 Tristan da Cunha group are very closely allied, and pteridologists are not agreed as to 

 their limits, as appears from Kuhn (Filices African*, p. 38). See note under Hymeno- 

 phyllum ceruginosum, ante, p. 162. Hymenophyllum obtusum was founded on Hawaian 

 specimens.

The form of this widely spread fern found in Amsterdam is identified by Fournier 

 with one which also occurs in South Africa, which, however, is not accorded even varietal 

 rank by Hooker aud Baker.
