A species of the D. silvaticum group, but smaller, proliferous, its pinnae distant, 
generally short, shortly pointed and long petioled, unequally auriculate, slightly 
lobed, one long sorus and some short ones on each lobe, very pale beneath. The 
specimen from San Ramon is very large with 16 pairs of pinnae 12 by 2 cm., 
and more deeply lobed than the others. 
I think that the plant that 'I took for D. silvaticum Presl in my first paper 
on Lolier’s Philippine ferns, 7 and of which I have not a specimen at hand, is 
7 Bull. Herb. Boiss. 6: 153.
