Sp. M. alata, *S'/)!. (v v.) ; M. cicutefolia, Kaidf. (v v.) ; 

 M. elegans, Eiidl. (v v.) ; M. fraxinea, Siii. (v v.) ; M. laxa, 

 Kze. (v V.) ; M. purpurascens, De Vriese (v v.) (Marattia 

 Ascensionsis, J. Sm. Gat., 1856) ; M. Verschaffeltiana, /. Sm. 

 (V v.). 



215.— EUPODIUM, /. Sm. (1841). 



Vernation and g-eneral chai-aoter as in Maratlia, differing 

 in the synangia being- pedicellate. 



Type. Marattia Icevis, Kaidf. 



Illust. Hook, and Bauer Gen. Fil., t. 118 ; Moore Ind. 

 Fil., p. 97 B. ; J. Sm. Ferns, Brit, and For., fig. 151. 



Obs. — This genus agrees with Marattia in general cha- 

 racter, but differs in the synangia being seated on a little 

 foot stalk (pedicel), similar to the genus Peranema. 



Sp). E. Kaulfusii, /. Sm. (ilarattia Kaidfussii, Hoolc. 2nd 

 Cent. Ferns, t. 95) (v v.). 



A rare Fern, native of Brazil. 



216.— DANaiA, Sm. (1793). 



Vernation uniserial, contiguous, decumbent ; sarmentum 

 thick, fleshy ; each frond rising- from between two short 

 stipukefbrm appendages, and having the stipes once or 

 more times articulated. Fronds pinnate, rarely simple, 

 1 to 3 feet high, the fertile usually somewhat contracted ; 

 pinnas opposite, linear-lanceolate, articulated with the 

 rachis. Veins forked ; venules parallel, their apices arcuate 

 and anastomosing at the margin. Synanrjia sessile, im- 

 mersed, linear contiguous, occupying nearly the whole 

 length of the venules ; each consisting of tvfo rows of 

 numerous laterally and oppositely connate cells, united into 

 a concrete mass, forming a linear synangia, each coll 

 opening by a circular pore.
