woods at about 1500 to 2000 ft. In fr. Dec. 1880. No. 56. Baker 

 (Syn. Fil.), and Mettenius in Kulin, Fil. Afr. p. 158, have referred 

 this species to D. drgans Sw. {D. dentictdata Mett.). If the spurious 

 venules so characteristic of D. elfgans are of any value for determining 

 species, this plant cannot be included in that species.

This cannot be distinguished from the South American species to 

 which Mettenius referred it. D. concinna Schrad. from South Africa 

 has the pinnte decreasing downwards as well as upwards, while the 

 fronds of D. thecifera H.B.K. , are sub-deltoid, with the pinnae largest 

 at the base. D. Schhnperi Hk. is a synonym of D. concinna Schrad. 

 There are specimens of D. thecifera H.B.K. in Herb. Mus. Brit., 

 from Madagascar collected by the Rev. Deans Cowan, and from 

 Equatorial Africa, east of Kiriandusi, 6100 ft., collected by Dr. J. 

 W. Gregory.
