CHARACTERS OF TRIBES AND GENERA. 115 



Sp. P. longifolia (Bl.) (v v.) (Polypodium contiguum, 

 Wall.) P. stenophylla (BL) 



Natives of the Malay and Philippine Islands. 



30. DICTYMIA, /. 8m. (1846). 

 Polypodium sp. R. Br, and Hook. Sp. Fil. 



Surculum short. Fronds simple, linear, or lanceolate, 

 coriaceous, smooth, 6 to 18 inches long, half an inch broad. 

 Veins reticulated, uniform, obscure. Receptacles punctiform, 

 compital. Sori oval, transverse uniserial, destitute of

Type. Polypodium attenuatum, R. Brown. 



Illust. Hook, and Bauer, Gen. Fil. t. 71, B ; Moore Ind. 

 Fil., p. 57, B ; J. Sm. Ferns, Brit, and For., fig. 15. 



OBS. On account of the similarity of the venation, 

 Presl associated the typical species of this genus with 

 several of the large compound fronded species constituting 

 his genus Dictyopteris, which belongs to the division Des- 

 mobrya. In habit the species agree with Phymatodes, but 

 differ in the venation being simply reticulated.

 Sp. Fil. and Gard. Ferns, t. 30) (v v.) ; D. lanceolata 

 (Polypodium lanceolatum, A. Cunn. HSS., Dictyopteris 

 attenuata, Hook, and Bauer t. 71, B, not Dictymia atten- 

 uata above given), 



The first is a native of Australia, the second of New
