uniforme (baud intus crenulata), celiulis marginalibus et costas 
secus opacis; soris segmenta prima acroscopica terminantibus, 
involucre anguste obconico immerso, limbo bilabiate libero bre- 
vissimo, late rotundato, subintegro, receptaculo clavato, breviter 
exserto. 
Sarawak, Mount Santubong, Foxworthy U58, June, 1908. 
Clearly distinguished by the opaque margin and Trichomanes-W^e sorus. 
The former is distinct in character from that of Crepidomanes ; and in 
spite of the latter, I believe there is no doubt as to the affinity and proper 
classification of the plant. 
HYMENOPHYLLUM CLEMENSIAE sp. nov. 
Euhymenophyllum minutum pilosum; rhizomate filiforme gla- 
brescente; stipitibus usque ad 1 cm longis, aut alatis usque ad 
pedes, aut fere omnino exalatis; fronde usque ad 3 cm alta, 1.5 
cm lata, utrinque angustata, fuscescente, ad alam latam pinnati- 
fida; segmentis obtusis pinnatifide vel dichotome incisis, seg- 
mentis ultimis integris, oblongis, obtusis, 0.7 mm latis, costis 
pilosis, pilis fuscis, simplicibus, subdeciduis, celiulis laminae mi- 
nutis, uniformibus ; soris ad vel ultra medium indusium immersis, 
parte immersa dense sed subdecidue pilosa non carinata, labiis 
liberis semiorbicularibus glabris, receptaculo clavato incluso vel 
breviter exserto.

Clearly distinguished in its subgenus by the long, simple hairs on the 
veins, particularly dense hairiness of the lower part of the involucre, and 
glabrous lips. The color and pubescence place it in the group of Euhymen- 
ophyllum which approaches Leptocionium. 
HYMENOPHYLLUM HOSEI sp. nov. 
Leptocionium lamina plana, rhachi late alata ; rhizomate crasso- 
filiforme, glabrescente, laete fusco ; stipite 10 ad 17 mm alto, fere 
ad basin alato; fronde 4 ad 5 cm alta, 2 ad 3 cm lata, ovata, bi- 
tri-pinnatifida, rhachi nigro-fusca, ubique late alata ala denticulis 
sparsis ornata; pinnis inframedialibus majoribus, ad alam rha- 
chidium ipsarum pinnatifidis, pinnulis superioribus simplicibus, 
inferioribus furcatis vel rarius pinnatifidis cum 3 ad 5 segmentis ; 
segmentis 2 ad 3 mm longis, 0.8 mm latis, obtusis, ubique anguste 
denticulatis, marginibus et dentibus nigrescentibus, lamina alibi 
fuscescente ; soris in segmenta prima acroscopica pinnarum supe- 
riorium insertis, parte inferiore obconica immersa, receptaculo 
crasso-setiforme, labiis fere aequilongo, involucre extus deorsum 
denticulate vel aspero vel fere nudo, ca. ad medium fisso, labiis 
ovatis inconspicue dentatis.
