acutis, leviter crenatis ; soris subremotis, submarginalibus, versus 
marginem apertis; parvis.

In position of sori, this is similar to Prosaptia ancestralis Copel. of Min- 
danao, but is very much more delicate and finely cut. Although it seems 
to me to be distinctly a Prosaptia, I have tried to find a name for this plant 
in Polypodium; but the only species it would seem even possibly to be is 
P. brevifrons Scort. in van Alderverelt’s Handbook, p. 600; and a diagnosis 
of this has never been published. Prosaptia semicrypta is distinct in several 
respects from Polypodium repandulum Mett. 
LOXOGRAMME FORBESII sp. nov. 
Rhizomate 3 mm crasso, radicibus pilosissimis more Antro- 
phyi aquam conservantibus dense obtecto; stipite 1 cm alto, ni- 
gro, valido; fronde ca. 60 cm alta, 10 cm lata, oblanceolata, 
acuminata, deorsum ad pedem fusco-siccam truncatam sensim 
angustata, integra vel minute crenulante, glabra, vix coriacea, 
infra pallida, costa superne tereta, subtus deorsum carinata; 
venis, pede sicca excepta, inconspicuis ; soris multis, a costa 
fere ad marginem protensis, prope costam curvis. 
No. 121. On trunk. 
I suppose this to be Raciborski’s var. Forbesii of L. blumeana Presl, but 
am quite unable to regard it as a variety of that species. The widened 
base has the same biological significance as those of Polypodium musifolium 
and P. linguaeforme and Asplenium Nidus. The texture is thinner and the 
veins more evident than in large forms of L. blumeana, and the appearance 
of the sori is very distinct. I have made Brooks’ plant the type of the 
species in order to avoid any possible doubt as to the plant which the name, 
as a specific one, fits. 
LOXOGRAMME BROOKSII sp. nov. 
Species unica generis foliis vero lanceolatis; rhizomate late 
repente, 1 mm crasso, paleis parvis angustis vetustate deciduis 
vestito; stipitibus distantibus, 1 cm longis; fronde uniforme, 
lanceolata, 12-20 cm alta, 10-12 mm lata, infra mediam latissi- 
ma, deinde utrinque angustata, valde acuminata, deorsum vix 
in alam decurrente, integra, coriacea; costa praecipue superne 
prominente; venis omnino inconspicuis, in parte majore frondis 
seriem unam solummodo includentibus ; soris brevibus, erecto- 
patentibus, non imbricatis, leviter immersis nec non superne 
elevatis. 
No. 12A. 
The fronds of Loxogramme lanceolata are usually widest above the middle; 
they are also much more decurrent than this plant, and have longer and 
broader sori, which are more elevated above the upper surface.
