LuzON, Province of Laguna, Mount Maquiling (Loher) April, 1906: Provincc 

 of Rizal, Ampalit (Loher) April, 1906. 



No. 51 Cuming "Polnfpodium adfinc Reinw." in Herb. Bureau of Science, 

 approaches Loher's speeimens eited above, except that the sori are not confined 

 entirely to the lobes and are less marginal. 



In many respects similar to U. canescens var. lobatum, but tlie accrescence of 

 tlie pinnse toward the apex and the increasing length of thc lobes toward the 

 tips of the pinnse is more accentuated. The sori are large, marginal, bordering 

 tlie lobes in a single series and tlie plant has not the harshness and grayish color 

 that distinguishes D. canescens, so that the present form can liardly be referred 

 to the preceding as a subspecies.

 hastata, antice plus minus aucta, pinnis dentato-serratis dentibus decum- 

 l)entibus, nervis goniopteridis, pinnatis inter costam marginemque areas 

 4 ad 5 formantibus quaque area nervulum liberum porrectum includente. 

 Fronde fertili longius stipitata, pinnis angustioribus magis remotis.
