186 CHAEACTEES OF TRIBES AXD QENEKA. 



92. — MiCEOFTEEit?, J. Sm. (noil Besv.). 

 Polypodmm, sp., aiict., and Hooh. 8p. Fil. 



Vernation uniserial, sarmentum slender, filiform, elonga- 

 ted. Fronds distant, 1 to 3 inches high, linear, gramineous 

 serrate or pinnate, opaque, rigid. Sori punctiform or 

 Blightly oval, terminal, solitary in each segment. 



Type. Polypodium fallax, Schlecht. 



Illust. Mett. Polyp., t. 1., f. 4 to 6. 



Obs. — The above character comprehends three very small 

 Ferns, specially differing from each other by the fronds 

 being simple and grass like in one, serrate-pinnatifid in 

 another, and pinnate in the third, but agreeing so closely 

 in their mode of growth and structure, that I deem it best 

 to associate them together as a distinct genus, and this I do 

 the more readily in consequence of their not possessing, 

 either collectively or individually, direct affinity with any 

 other genus. 



* Fronds linear, entire. 



Sp. M. graminoides, /. Sm. 



** Fronds linear, serrate. 



Sp. M. monticole, Kloi. 



*** Fronds pinnate, pinnce cuneiform. 



Sp. M. fallax, Schlecht. 



These three species are vei-y local, the first being found 

 in Jamaica, the second in Columbia, and the third in 

 Mexico. 



93. — Adenophoeus, Gaud. (1826). 

 Polypodium sp. auct., Hook. Sp. Fil. 

 Vernation sarmentose. Fronds contiguous, caespitose, bi- 

 sub-tripinnatifid, 3 to 11 inches high, oblong lanceolate,
