specimens in U!). 
D. protensa is the best-known member of a group of African ferns that all have 
been referred by some authors to D. protensa (resp. D. subquinquefida), while others 
have created a number of species. Lacking sufficient material I shall not try here to 
clear up the real nature of these African forms, but a minute comparison between 
them and very similar forms occurring in America was necessary for settling the 
question, whether the American plants belong to the same species as the African 
ones or not. I have arrived at the conclusion that the common American form 
cannot be separated from D. protensa as a species, but there are some small differ- 
ences so that I find it justifiable, at least provisionally, to name the American plants: 
var. funesta (Kze.) C. Chr. Ind. 286. 
Syn. Aspidium funestum Kunze, Linnaea 9: 96. 1834; Mett. Aspid. no. 169. 
Nephrodium funestum Hook sp. 4: 129 tab. 259. 1860; Jenman, W. Ind. and 
Guiana Ferns 219. : 
Aspidium Nemes Willd. sp. 5: 215 (part.?) 1810 (non Sw. 1801); Kze. Flora 
1839': Beibl. 33, KI. Linnaea 20: 371. 1847. 
Aspidium acrocarpon Fée, 11. mém. 84. 1866. 
Type from (N.?) Brazil: Ega, leg. Porppic (not seen). 
In habit, colour, texture, pubescence, venation etc. the variety does not differ 
from the African form, but it is as a rule larger, the stipe and rachis furnished with 
several small entire fibrils that are very few or absent in true D. protensa. The sori are 
generally small, supramedial or almost: submarginal and covered with firm, persistent 
_indusia, while the sori of D. a beekeere are larger, rather medial and their indusia 
12°
