Nearest D. cultratum Presl, but larger, with brown paleoe, nonauricled pinnge, 
and the terminal pinna entire or with a single pair of basal lobes. D. xipho- 
phylluni (Baker in Joiirii. of Bot., 1879, p. 207), of Borneo, has numerous 
nai’rower pinnas; my D. pulauanense difl'ers from it ehiefl 3 ^ in having short sori 
falling far short of the margin.

In size, and in the measure of dissection of the frond, this species is veiw 
like D. graimnitoides Presl; in color and texture it is more like D. si/lvaticum. 
Fruiting fronds are found less than 5 cm. in height, including the stipe. It 
bears the name of R. S. Williams, of the New York Botanical Garden, my com- 
panion Avhen it was found.
