222 CHARACTEES OF TRIBES AND GENERA. 



Sp. A. nodosa, Presl Bedd. F. Brit. Ind., pi. 93 (Aspidium 

 foliolosum, Wall). 



114. CAMPTODIUM, Fee (1852). 

 Pachyderis, J. Sm., 1854. Nephrodium sp., Hook. Sp. Fil. 



Vernation fasciculate, erect, acaulose. Fronds stipate, 

 deltoid, cordate, tri- or pedately-lobed, thick, coriaceous, 

 smooth, 8 to 12 inches in length. Veins obscure, flabel- 

 lately forking in the lobes. Receptacles punctiform, terminal. 

 Sori large. Indusium reniform. 



Type. Aspidium pedatum, Desv. 



OBS. This genus is founded on a solitary Fern, which 

 differs from all free- veined Aspidece in its fronds being cor- 

 date, sub-entire, or more or less lobed, and of a thick, 

 coriaceous, firm texture, and obscure veins ; its peculiar 

 habit induced me to characterise it as a distinct genus, 

 under the name of Pachyderis, but which is superseded by 

 the earlier one of Fee. It may be considered as holding a 

 position intermediate between Polystichum and Lastrea. 



Sp. C. pedatum, Fee. 



Native of the West Indies, Jamaica. 



115. ADENODERRIS, /. Sm. (1852). 

 Aspidium Sect. Polystichum, Hook. Sp. Fil. 



Vernation fasciculate, erect, acaulose. Fronds 6 to 8 

 inches in length, oblong, lanceolate, pinnatifid, densely 

 covered with pilose glands, decurrently attenuated to a short 

 stipe. Veins pinnately forked. Eeceptades punctiform, 

 medial. Sori round. Indusium orbicular, occasionally 

 reniform. 



Type. Aspidium glandulosum, Hook, and Grev.
