LEAFLETS OF PHILIPPINE BOTANY [Vor. III, Arr. 45 
ad 15 cm. alta, lanceolata, acuminata, deorsum pinnata, sur- 
sum pinnatifida; segmentis fere integris, pinnis dentatis, vel 
infimis remotis brevi-pedicellatis lobatis, obtusis, venulis mar- 
ginibusque setosis, aliter glabris; venulis furcatis, liberis; 
soris elongatis, nudis; sporangiis atrobrunneis, rarissime seta 
ornatis; sporis verrucosis. 
Mt. Apo, at falls of Cati creek, alt. 1750 m., No. 11508. 
This little fern suggests D. africana (Desv.) C. Chr. and 
D. philippina (Presl) C. Ohr., the latter of which is identical 
with D. aoristisora (Harr.) C. Chr. D. gymnocarpa is super- 
ficially enough like Athyrium grammitoides (Presl) readily to 
permit confusing them. 
Dryopteris calva Copel. spec. nova. 
Species gregis D. gracilescentis, costis infra glabris, soris 
costulae quam margini propioribus, D. gracilescente haud aliter 
distinguenda. 
Gravelly soil along Seriban creek, Mt. Apo, alt. 1800 
m., No. 11485. "''Paeat-pang-pang."' 
This is so near to D. gracilescens (Bl.) O. K. as to be 
readily mistaken for it. However, in the seven collections 
of that species which I have from various parts of its range, 
there is not a specimen the costae of whose pinnae are not 
conspicuously hairy beneath, nor whose sori are as close 
to the eostule as those of D. calva. The surface of D. calva 
is not at all glandular, but I find D. gracilescens somewhat 
variable in this respect. 
Dryopteris Foxii (Copel.) Christ in P. J. S. 2, C (1907) 208. 
In wet rock crevices by Sibulan river, alt. 900 m., 
No. 10832. ‘‘Libagod.’’ 
Throughout the Philippines, on rocks submerged by 
floods. 
Dryopteris viscosa (J. Sm.) O. K. 
Terrestrial in mossy forest, Mt. Calelan, alt. 2350 m., 
No. 11354. ''Saladat.'' Collected also at 1800 m. alt. on 
Mt. Apo by DeVore and Hoover and myself. This Apo 
form is very small and only obscurely glandular.
