A speeiea of the D. silvaticuni group, but smaller, proliferous, its pinnae distant, 
generally short, shortly pointed and long petioled, unequally auriculate, sli«fhtly 
lobed, one long sorus and sonic short ones on each lobe, very pale beneath. The 
specimen from San Ramon is very large with IG pairs of pinn.*c 12 by 2 cm., 
and more deeply lobed than tlie others. 
I think that the plant that T took for />. silvaticum Presl in luj' first paper 
on Loher^s Philippine ferns,^ and of which 1 have not a specimen at band, is
