This is a fern of such size that a fragment of the frond can not be determined 
with certainty, and descriptions which do not include the caudex nor even the 
stipe are quite insufficient. In listing synonyms I have merely followed Chris- 
tensen, and do not suppose that if the entire plants were known all of these names 
would be found to apply to one species. As to the name I have chosen, there is 
nothing in the diagnosis to show that it differs from any specimen I have listed, 
it is regarded by Christensen as a synonym of D. polypodioides, and is the oldest 
name available in Athyrium. Neither do I regard all the Philippine plants pro- 
visionally called by this name as being conspecific ; but since descriptions are 
inadequate and the many specimens at my disposal from India and Malaya are 
likewise incomplete, the best that can be done is to make this for the present a 
“Sammelspecies.” Diplazium asperum Bl. ( Athyrium , Milde) is still another 
species, which, for the reasons just given, I can not determine positively. I have 
several specimens from Java, pieces of fruiting fronds, which I can in no way 
distinguish from young specimens of A. Blumei ; but having no doubt as to the 
correctness of Blume’s judgment, I have not combined the species. 
Athyrium asperum (Bl.) Milde, just discussed, is also reported from the Phi 1 - 
ippines. We have here, in fact, two ferns which will fit Blume’s diagnosis, one 
with a stout stipe and one with a slender stipe. Old and densely fruiting fronds 
of either are practically indistinguishable from the preceding species. Raciborski, 
Pteridophyten der Flora von Buitenzorg, 227-8, reduces asperum to polypodiodes. 
The Mindoro plant, Merrill 5918, which I referred to D. asperum, Philip. Journ. 
Sci. 2 (1907) Bot. 129, does not exactly fit Blume’s diagnosis, and can not nearly 
be included in Raciborski’s description.

This differs typically from A. asperum in that the pinnules are not at all 
cuneate, and the sori in fully fruiting specimens are confluent. Near this, but 
hardly identical is Elmer 10006, from Horn of Negros Mountain. 
I should of course have taken up Milde’s name if I had suspected the identity 
of A. affine; but it is only as this paper is being finished, two years after the 
publication of D. fructuosum, that I receive one of the lower pinnules of Cuming 
167, which seems to be the same fern. We already had a fine specimen of the 
upper end of a frond of this fern, but in this group of species it is often im- 
possible to identify such parts.
