PTERIDOPHYTA HALCONENSES. 
129 
Diplazium palauanense Copel. 
In humid forests at 200 m. alt. (No. 5915). 
Hitherto known from Palawan only. 
One large frond has 16 pairs of pinnae, the largest nearly 40 cm. long but only 
3 cm. broad. A few “sori” are scolopendroid and some sori reach the margin; 
in spite of this modification of its character, however, the species is very distinct 
from D. bantamense. 
Diplazium Woodii Copel. n. sp. 
Rhizomate erecto, 1 cm. crasso; stipitibus confertis, 20-30 cm. altis, 
2 . mm. crassis, rectis, basibus branneo-nigris, dense brunneo-falcato- 
paleaceis, sursum rhachibnsque stramineo-brunneis, paleis pancis 2-3 mm. 
longis castaneis angustis distantibus vel deflexis sparsis vestitis; fronde 
40-50 cm. alt a, vix 20 cm. lata;, acuminata, bipinnatifida ; pinnis ntroque 
latere 12-17, medialibns maximis horizontalibns brevi-pedicellatis 2 cm. 
latis, acnminatis, rhachin versus truncatis, profunde pinnatifidis, glabris, 
herbaceis, supra atro-viridibus infra olivaceis, costa castanea; segmentis 
oblongis, 5 mm. latis, subfalcatis, oblique truncatis serrulatis, ala 1.5 
mm. lata connexis sinubus ca. 1 mm. latis interpositis, venulis simplicibus, 
5-6-jugatis ; soris 2-3 mm. longis, obliquis, rarissime diplazoideis costa 
remotis nec ad marginem attingentibus. 
In silvis, 300 m. s. m. (No. 5917). 
This would seem to be very near to Blume’s D. acuminatum, so far as the 
original description of that species shows, but differs from Christ’s undoubtedly 
correct interpretation of that species 4 in the paleaceous stipe, deeply cut pinnae 
and in some minor details: I would not call it in the Japonicum group. 
It is dedicated to Major-General Leonard Wood. 
Diplazium asperum Bl. 
In forests at 300 m. alt. (No. 5918). Fronds 2 to 3 m. high on stipes 1 m. 
high. The same fern has been found near the base of Mount Halcon by McGregor 
(No. 277). 
India, Java. 
AN ISOGON I U M Presl. 
I am by no means convinced that this genus will stand, but it is at least as 
distinct from Diplazium as the latter is from Athyrium, and as all our species 
already have names in Anisogonium, its use here does not encumber nomenclature. 
Anisogonium cordifolium (Bl.) Bedd. 
On ridges on the mossy forest at 1,400 m. alt. (No. 5909), fronds all simple; 
on forested ridges at 850 m. alt. (No. 5910), fronds all pinnate and the venation 
approaching that of A. alismaefolium. 
Luzon and southward. 
Malaya. 
Anisogonium alismaefolium (J. Sm.) Christ. 
In humid forests at 200 m. alt. (No. 5911), fronds all simple, upper surface 
with beautiful metallic luster. 
Luzon, Mindanao. 
Celebes.
