The position of this species is uncertain ; it seems most likely to be a 
relative of Diplazium asperum Bl. The less dissected frond, with corre- 
spondingly long sori, suggest an immature plant; but it is fruiting freely, 
and juvenile specimens of the ferns of this group, as known to me, do not 
grow through such a stage as this. 
ATHYRIUM PARIENS Copel. in Philip. Journ. Sci. 3 (1908) Bot. 299. 
Mount Salak, alt.' 1,600 m, No. 631 in part. Already known from Min- 
danao and Negros. 
This is very possibly identical with ATHYRIUM FORBESII (Baker) 
{Asplenium Forbesii Baker Ann. Bot. 5 (1891) 312). 
ATHYRIUM SUBSERRATUM (Bl.) Milde. 
The origin of this species with simple fronds on adult plants, from 
ancestors with compound fronds, is attested by the occurrence of bipinna- 
tifid fronds on juvenile specimens. I have previously pointed out that the 
species with dissected fronds are the more primitive.* 
The collection contains two other apparently new Athyria, but as the 
material is imperfect, they are not described.

These and various other Javan specimens in Manila herbaria are very 
uniform, and constantly thoroughly distinct from Pteris pellucida Presl, of 
which our material is naturally ample. The differences are well given in 
the brief original diagnoses. P. venulosa has the axes red and polished, 
most of the leaflets decurrent-connected, leaflets broader, the sterile not 
wavy, much less acuminate, and coarsely crenate-serrate instead of finely 
and very sharply serrate toward the apex. Its veins are less conspicuous, 
but the hydathodes more so.
