CHARACTEES OF TRIBES AND GENERA. 211 



receptacle. In the "Species Filicum" only one species is 

 described, but according to my view, I consider there are 

 two, natives of Malayan and other Eastern islands. 



Species. M. Javanica, E. Br. (v v.) ; M. asplenioides, 

 /. Sm. (Sphcerostephanos J. 8m. in Hook, and Bauer Gen. Fil.) 



110. FADTENIA, Hook. (1842). 

 Hook. Sp. Fil. 



Vernation fasciculate, acaulose, becoming caespitose. 

 Fronds simple, dimorphus, 5 to 6 inches long, sterile, lanceo- 

 late, attenuated, decumbent, its apex proliferous ; fertile 

 fronds erect, linear spathulate, obtuse. Veins forked, venules 

 acutely anastomosing, free next the margin ; the lower ex- 

 terior venule in the costal areoles free, its apex soriferous. 

 Receptacle oblong. Indusium large, oblong reniform. Seri 

 contiguous, transverse uniserial on each side of the 

 costa. 



Type. Fadyenia prolifera, Hook. 



Illust. Hook, and Bauer, Gen. Fil., t. 53, B. ; Hook. 

 Fil. Exot., t. 36 ; Moore Ind. Fil., p. 68 ; J. Sm. Ferns, 

 Brit, and For., fig. 69 ; Hook. Syn. Fil., t. 5, fig. 47. 



OBS. This genus is founded on a remarkable Fern, a 

 native of Jamaica and Cuba. In habit it does not well 

 associate with any of the Aspidece group, except Polystichum 

 rhizophyllum, with which it agrees in the sterile fronds, 

 being decumbent and proliferous ; in that character as also 

 in the texture and colour of the fronds, and in the oblong, 

 apparent double indusium, seems to indicate a greater 

 relationship with Antigramma in the tribe Aspleniece, rather 

 than with any of the genera of the present sequence. 



Sp. F. prolifera, Hook, (v v.), (Aspidium proliferum, Hook, 

 and Grev. Ic. Fil., t. 96).
