ialibns maximis, 50 cm. longis, 13 cm. latis, fere horizontalibns, acumi-

stipitatis 7 cm. longis, 1 cm. latis, serrato-acuminatis, deorsum ad rhachin 
infra perpaleaceam paleis biformibus, supra breve denseque villosum 
pinnatis; pinnulis 11 anguste abovatis, obtusis, adriatis, minute nec lente 
erenato-serratis, tenue coriaceis, supra subnigris, glabris, infra atro-oli- 
vaceis, costis deorsum paleis bullatis ciliatis obtectis, aliter glabris; ve- 
nulis sterilibus inferioribus plerumque furcatis, fertilibus simpbcibus; 
soris costalibus; pinnulis prasertim fructuosis contractis, soris laminam 
totam complentibus.

A most striking species remarkable for the dark color of the whole frond and 
especially for the shiny black stipe and rachis.

On ridges in humid forests at 250 m. alt. (No. 6050). 
Madagascar to Polynesia.

in Formosa. 
Throughout the Philippines, not common.

Lygodium M err i 1 1 i Copel. n. sp. (PI. IV.) 
Species distinctissima pinnis sessilibus, pinnulis pinnatis, pinnulis 11 
haud articulatis, segmentis fertilibus sparsis, venulis ubique anasto- 
mosantibus. 
In dumetis scandens, 300 m. s. jn. (No. 6057). 
In all probability a relative of Lygodium flexuosum, rather than of any other 
species with reticulate venation.
