Sarasin 1022, from Central Celebes, cited by Christ with those of Koorders, has sterile pinnae to 6 x 1.5 cm and sporangia strongly setiferous. v.A.v.R.'s description of D. acrostichoides was based on Koorders's specimens at Bogor named by Christ; these were not cited by Christ in 1898; I have selected Koorders 17153 as the type of v.A.v.R.'s name.
