A duplicate of Copeland's No. 1478, occ-urring in the Buiten. 

 zorg Herbarium, has the barren lobes bluntly rounded at the 

 apex, the fertile more or less acute when seen from above, but 

 the compressed projections blant or obliquely retuso-truncate 

 when seen from the side.

Lowest segments sometimes rather remote from the others, 

 elongated and pinnatifid again, as in Pt. salakensis y.J..v.i^. (Bull. 

 Btz., 1912, VII, 26), but with the lowest secondary segments 

 close to the rachis, not decurrent. -The relation of this to Pt. 

 salakensis, I think, is as that of Pt. quadriaurita Retz, to Pt. 

 longipinnula Wall.
