CHAKACTEKS OF TRIBES A-VD GENERA. 121 



Pp. D. fui'cata {Willd.) (v v.) ; D. subpiunatifidum, 

 (Moore) . 



Obs. — The latter species is probably a variety of the 

 first, the chief difference being- that in some specimens the 

 venules of the lower part of the frond when sterile are 

 free. 



Natives of the West Indies and Tropical America. 



37. Neueodiuji, Fee (1812). 

 Tcp.niiis sp. Sio. : Hooh. Sp. Fil. 



Surculum short, cajspitose. Fronds contiguous, simple,

 portion partially contracted and fertile. Veins obscure. 

 Venules compoundly anastomosing. Eeceptacles compital,

Type. Tceniiis lanceolata, R. Br. 



Illust. Hook. Fil. Exot., t. 45 ; Moore Ind. Fil., p. 18, B ; 

 J. Sm. Ferns, Brit, and For., fig. 17.

 slightly contracted. 



Sp. N. lanceolatum {Sio.) (v v.) 



Native of the West Indies and Tropical America.

Lindsece sp. and. ,- Houk. Sp. Fil. 



Surcidimi short. Fronds dimorphous, 6 to 12 inches long, 



stipitate, opaque and subcoriaceous, the sterile ones 



cordate, entire, or trilobed ; fertile frond linear, more or
