Subspecies of C. meniscioides (Willd.) Pr. ; it differs by its very rigid 

 texture, the more numerous pinnae, which are horizontal, approximate, and 

 imbricated in the sterile frond, and by its very distinct and raised veins.

Rachis, like the stem, shining, black, throughout densely clothed with 

 I'ed-brown, deciduous tomentum, consisting of long, hairlike, thin scales 

 with a somewhat broader base; pinnae often lobed towards their base or 

 with a distinct auricle on the upper side; under surface (and sometimes 

 also the upper one) paleaceous along the veins; texture very rigid and 

 leathery; whole plant smaller than the type.

The plant of Mosen is a curious, evidently abnormal form with the 

 pinnae auricled on both sides and sori extending into the auricles. Our 

 variety somewhat resembles A. caudatum Forst., but the position of the 

 sori is that of A. serra, and apparently it is a xerophilous form of this 

 species. 



— Max. Kuhn in his „Filices africana?" pag. 208 says: ^Aspleiumi 

 Nigritianum Hook, nullo modo ab Aspleno pedicularifoUo St. Hil. (Voy. 

 d. 1. dist. d. Diam. 1, 380) fide spec. orig. distingui potest, quod nomen 

 ex prioriatis legibus anteponendum est". — A. nigritianum Hook, is a 

 well-marked species from the islands of west-tropical Africa, but by recent 

 authors not recorded from Brazil, and the plant of Saint Hilaire is not 

 noticed either by Baker in „Flora brasiliensis" or by Fee in his „Grypt. 

 vase, du Bresil". hi our herbarium I find two specimens collected by 

 Glaziou in the state of Minas Geraes, marked on the sheets A. rJiizophyl- 

 lum Kze. by Baker, but they are evidently extremely different from this 

 species. The dried plants are black; rhizome woody, strong, oblique or 

 erect; frond bipinnate, lower pinnae reduced, ternate, the upper ones with 

 several short-stalked rhomboidal or nearly fan-shaped, dentate pinnules; 

 young rachises and stems clothed with dark-brown scales. The specimens 

 exactly agree with the description and figure of Hooker (2 century tab. 44), 

 and clearly they belong to the same species. Then the synonymy and 

 distribution of the species are as follows :
