Diplazlum pctiolare Presl seems by its diagnosis to be a most distinct species. 
Included in Cuming .TJO, the type collection, wo biive at least one fertile frond 
which corresponds closely enough to the description to be without doubt the 
same plant. This specimen might liuve come, so close is the resemblance, from 
the same plant as my Xo. 1678, from San Ramon. We have the same form 
from Lanuo, 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 tliere is no open gap between this 
and other forms, it seems best to unite tliem. Our specimen of Cuming 3/f9, 
referable here, has the piiuuv lobed less than half way to the costa, but decidedly 
deeper than in typical .1. pinnaium. The species is variable in this respect in 
other lands as well as liere. As to the pubescence, it is unusually marked in 
"/). peiiolare;" hut the rachis bears some, if not so many, hairs of the same fine 
type, in tlie channeled upiH'r side of the rachis of every specimen of A. pinnafum 
I have seen, from whatever source; and in Javun as well as Philippine specimens 
some of this pubescence is always (at least in my plants) present on the stalk . 
of the pinna*, and at least wliile young, on the costa. On the convex side of the 
rachis, it mav or mav not he evident. 
It has already been noted that Christensen treats D. tenerum as this species. 
We have also this fern uiuler Cuming SSS, 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. grammitoidea, as Presl says D. tenerum is. 
35. Athyrium cultratum (Presl) Milde. 
Luzon, Cuming li)9; Mount Banajao, Efmer 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.

Mindoro, Merrill 5016, much less cut than is typical: Miudauai), Copcland

The sessile, obtuse pinnae are finely and regularly bicrenulate.

I have not seen Asplen'mm camnrinum Baker, described from Cuming*!^ collec-

is specifically difierent from A. pallidum.
