Mindanao, Davao, Monte Apo, Copcland 1490 (in part). 



Nearest D. cultratum Preal, but larger, with brown paleae, nonauricled pinnae, 

 and the terminal pinna entire or with a single pair of basal lobes. D. xipho- 

 phyllum (Baker in Journ. of liot., 1879, p. 207), of Borneo, lias numerous 

 narrower pinna:; my I), palananensc differ* from it chiefly in having short sori 

 falling far short of the margin.

Mindanao, Zamboanga, San Ramon, Copeland 1(548. Alt. 500 m., ad terrain, 

 Feb., 1905. 



in size, and in the measure of dissection of the frond, this species is very 

 like D. yrammitoides Presl; in color and texture it is more like I), sylvuticum. 

 Fruiting fronds are found less than 5 cm. in height, including the stipe. It 

 bears the name of R. S. Williams, of the New fork Botanical Garden, my com- 

 panion when it was found.

This has the aspect of D. williamsi, but is larger, more cut. with brown, 

 broader chaff, and horizontal rhizome.
