Diplazium petiolare Presl seems by its diagnosis to be a most distinct species. 
Included in Cuming 31/9, the type collection, we have at least one fertile frond 
which corresponds closely enough to the description to be without doubt the 
same plant. This specimen might have come, so close is the resemblance, from 
the same plant as my No. 1078, from San Ramon. We have the same form 
from Lanao, as well. If the species were otherwise very uniform, I would be 
willing to maintain this form as distinct; but as the collections in hand show 
that it is a variable species, and indicate that there is no open gap between this 
and other forms, it seems best to unite them. Our specimen of Cuming 31/9, 
referable here, has the pinnae lobed less than half way to the costa, but decidedly 
deeper than in typical A. pinnatum. The species is variable in this respect in 
other lands as well as here. As to the pubescence, it is unusually marked in 
“D. petiolare ;” but the rachis bears some, if not so many, hairs of the same fine 
type, in the channeled upper side of the rachis of every specimen of A. pinnatum 
I have seen, from whatever source; and in Javan as well as Philippine specimens 
some of this pubescence is always (at least in my plants) present on the stalk 
of the pinnae, and at least while young, on the costa. On the convex side of the 
rachis, it may or may not be evident. 
It has already been noted that Christensen treats D. tenerum as this species. 
We have also this fern under Cuming 333, the number cited by Presl. But this 
number seems to include also A. vestitum, and a number including these two 
need not be trusted not to include still others. This species is at any rate not 
closely related to A. grammitokles, as Presl says D. tenerum is. 
35. Athyrium cultratum (Presl) Milde. 
Luzon, Cuming 199; Mount Banajao, Elmer 9012, rare on banks of water 
courses in dense woods, alt. 850 m. It is probable that Cuming collected this 
fern in the same vicinity. 
30. Athyrium crenato-serratum (Bl.) Milde. 
Mindoro, Merrill 5916, much less cut than is typical: Mindanao, Copeland 
1661. 
Malaya. 
Javan specimens vary widely enough to include the Mindoro plant. 
37. Diplazium inconspicuum Christ in Bull. Herb. Boiss. II 6 (1906) 1000. 
(Mabacal, Rizal Province, Loher, Montalban, holier.) 
The sessile, obtuse pinnte are finely and regularly bicrenulate. 
38. Athyrium pallidum (Bl.) Milde. 
Luzon, Cuming 188; Rizal Province, Bur. Sci. 1801 Ramos; Mount Banajao, 
Elmer 9016: Mindoro, For. Bur. 9950 Merritt: Negros, Copeland s. n. : Palauan, 
Bur. Sci. 579 Foxworthy : Mindanao, Lanao, Clemens s. n. ; San Ramon, Copeland 
161/1 ; Davao, Copeland 956, 11/97. 
Malaya, Queensland. 
I have not seen Asplenia m camarinum Baker, described from Cuming’s collec- 
tion. number not stated; and I can not discern from the description wherein it 
is specifically different from A. pallidum.

Mindoro, Merrill 1776, Whitford 11/02: Leyte, Cuming 303: Mindanao, Suri- 
gao, Bolster 3.89; San Ramon, Copeland 737, 151/1/; Davao, Copeland 663, 91/9:
