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

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

 this species to D. degaiis Sw. {D. denticulata Mett.). If the spurious 

 venules so characteristic of D. I'lcgann are of any value for determining 

 species, this plant cannot be included in that species.

 Delamboa, near Sange, July 1856 ; and the other, No. 125, appeared

This cannot be distinguished from the South American species to 

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

 has the pinnae 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. Schimperi 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.
