Hab. South Brazil. Province of St. Catherine, Chamisso, Selluiv. 

 Minas Geraes, Lanysdorff. Stony shady places. Province of St. Paul, 

 Brazil, Serra de Natividade, Gardner, n. 3556. — A much larger, stouter 

 and more robust plant than Cassehcera tTiphylla. The caudex is similarly 

 horizontal, bearing the same wiry roots. The stipites are less crowded ; 

 the rachis a span to a foot long, less glossy and ebeneous than the preced- 

 ing species. The frond is simply pinnated, as shown by Kaulfuss and 

 Kunze and as in our specimens from Natividade : but not unfrequenily 

 bipinnate, as represented by Martius, and as in our specimen from Sellow. 

 The pinnae and pinnules are 2 inches and 2^ inches long : and the black 

 midrib runs up almost to the a])ex. In our best specimen from Gardner 

 the scales of the caudex are bright lawny. 



3. Cass, gleichenioides, Gardn. ; fronds bipinnate, pinnules 

 petiolate linear-elongated deeply pinnatifid or even pinnated, 

 lobes or ultimate pinnules orbicular-subquadrate when dry 

 recurved the margin (beyond the involucre) thickened entire.

Hab. Bushy rocky places, Diamond district, Brazil, Gardner, n. 5295. 

 — Imagine an unusually large specimen of Cass, pinnata more divided 

 (i. e. more bipinnated than usual), and instead of having the shallow lobes 

 to that species, to have those lobes, or the sinuses of those lobes, cut down 

 to the very rachis into roundish lobes or ultimate pinnules with the mar- 

 gin or edges of those pinnules thickened, and you have an idea of the 

 structure of the present species. The scales of the caudex of this as well 

 as of the preceding species, are bright tawny, not black as we find them in 

 (Jass. triphylla. Our tallest fronds of this are 6 — 7 inches long, and the 

 deeply divided, convex and nearly opposite ultimate pinnules of a rounded 

 form, have quite the ajipearance peculiar to some Gleichenia, whence 

 Mr. Gardner's appropriate specific name. We find the capsules upon long 

 stalks, which seem to be characteristic of the other species. Although this is 

 found in tropical Brazil, it is probably a mountain plant : and all the spe- 

 cies may be said to belong to the temperate rather than tropical regions.
