COPELAND. 
opacis, mox glabrescentibus, fertilibus baud diversis; margine 
reflexo sat lato. 
Mindanao, Agusan Subprovince, Mount Hilonghilong, alt. 115 m, C. M. 
Weber 1H3, March, 1911. 
A relative of Pteris opaca J. Sm. but much smaller; easily distinguished 
from all forms of Pteris cretica by the simple and entire, decurrent, coria- 
ceous pinnae. 
Dryopteris dichrotricha Copel. sp. nov. 
Thelypteris, D. (Nephrodio) adenophorae affinis; rhizomate 
erecto, paleis angustis castaneis vestito ; stipite 30 cm alto, brevis- 
sime hirsute, sursum pinnis in auriculas minutas reductis donate ; 
fronde 35 cm alta, 12 ad 15 cm lata, acuminata, ubique densis- 
sime minute albido-setosa ; pinnis utroque latere ca. 20, sessilibus, 
acuminatis, 10 ad 15 mm latis, | ad costam pinnatifidis; utroque 
facie ad costa venasque setis majoribus vestitis; venis simplicibus, 
utroque latere 6 ad 9 ; soris medialibus, indusio persistente, 
setose. 
Mindanao, Agusan Subprovince, Mount Hilonghilong, alt. 120 m, C. M. 
Weber 1173, March 1911. Nearer to D. adenophora than to any species 
with free veins. 
Dryopteris mesodon Copel. sp. nov. 
Species gregis D. dissectae, stipite ad basin paleis linearibus 
castaneis 15 mm longis vestito, supra sparse spinuloso; fronde 
35 ad 40 cm alta et lata, rhachibus castaneis, supra costisque velu- 
tinis ; pinnis infimis oppositis multo maximis, stipitatis, deltoideis, 
valde acuminatis; earum pinnulisi infimis stipitatis, acuminatis; 
harum pinnulis^^ brevistipitatis, cordatis, acutis, ad basin pin- 
natis; pinnulis”’^ adnatis, obtusis, grosse serratis, utroque latere 
una ; pinnulis ordinum omnium superioribus decurrenti-connexis, 
et ala decursa saepe dente uno ornata ; segmentis penultimis acute 
grosse serratis, acutis, oblanceolatis ; soris a costa remotis, parvis ; 
indusio persistente, minute praecipue ad insertionem puberulo. 
Mindanao, Agusan Subprovince, Mount Hilonghilong, alt. 120 m, C. M. 
Weber 1176, March, 1911. 
This bears the same relation to Dryopteris dissecta that D. pnrpurascens 
does to D. sparsa. Its nearest relative is D. balabacensis Christ.

Sagenia, rhizomate ca. 1 cm crasso, suberecto, apice paleis 
angustis atrocastaneis 4 mm longis dense vestito; stipite 20 ad

ad 5 mm latam pinnatifida; segmentis plerumque 5, sat remotis, 
late lanceolatis, sinuatis, obtusis, versus costam angustatis, her- 
baceis, lamina glabra; venis minute glanduloso-piliferis, venis 
primariis remotis, fere ad marginem protensis, areolis primariis
