Caudex creeping, covered with numerous, chaffy, brown scales, and sending 
forth many flexuose, blackish, slightly branched fibrous radicles. Stipes 
and rachis hairy. Sterile fronds, several from the same caudex, scarcely — 
more than 2 inches long, pinnated, with about 7 or 9 obovato-cuneate, 
opposite leaflets, which are terminated by an odd one; these are strongly 
veined, crenate at the extremity, hairy beneath, scarcely so above. The 
fertile frond is supported upon a rather long stalk ; and from the summit 
of this stalk, at the base of the frond, arise the 2 oblong, compound spikes 
of fructificalion, standing upon rather long, glabrous peduncles. Capsules 
crowded,but somewhat secund ; each is obovato-spherical, reticulated, sur- 
mounted at the top with a concentrically striated swelling, and opening 
outwardly by a vertical fissure. Seeds numerous, spherical, beset with 
numerous elevated points. 
I am indebted for my specimens of this pretty little fern to 
Professor Rappr of Florence, who gathered it in clefts of old 
walls, and especially near the aqueduct which conveys the wa- 
ter from the mountains of Corcovado to the city of Rio Janeiro 
in the Brazils. That gentleman has described it under the 
name of A. repens, quoting doubtfully the 4. tenella of Ca- 
VANILLES; but I think there cannot be a question of its iden- 
tity with the Osmunda humilis of CAVANILLES, whose figure
