1152 LEAFLETS OF PHILIPPINE BOTANY [Vor. IV, Arr. 61 
being my number 1899. The Indian and African plants, as far as 
I know them, are different, and the African plant at least is 
distinct from T. adenophora. 
ADIANTUM Linn. 
Adiantum cupreum Copel. spec. nova. 
A. opaco Copel. affine, quo frondibus plerumque minoribus, 
pinnulis plus orbicularibus et minus opacis, sub luce oblique

No. 12400, Sibuyan Island, alt. 450 m. 
“Small terrestrial tufts in fertile soil among rocks of a deeply 
shaded declivity...... Fronds strongly recurved or nearly 
flat, pointing down hill" The stipes are 5 to 15 em. long; 
fronds 10 to 15 em. high and wide; coriaceous reflexed margin 
("indusium") 3 to 5 mm. wide, 1 to 1.5 mm. deep. Like A. 
opacum, this has the sporangia confined to the veinlets, and 
pinnules deciduous and bordered by a very narrow hyaline 
margin. A. opacum is also copper-colored by very oblique 
reflected light, but much less brilliantly so.
