A species of the D. silvatieum. group, but smaller, proliferous, its pinnse distant, 

 generally shoit, shortly pointed and long petioled, unequally auriculate, slightly 

 lobed, one long sorus and some short ones on each lobe, very pale beneath. The 

 specinien from San Ramon is very large with 16 pairs of pinn« 12 by 2 cni., 

 and more deeply lobed than the otliers. 



I think that the plant that I took for Z). silvaticum Presl in my first paper 

 on Lohrr's Philippine ferns,' and of whieh 1 have not a specimen at hand, is
