A slender small form, the fronds rather short and broadly deltoid, the stipes 

 rough, slender, tawny, the segments pectinate, free at the base, papyraceous, 

 yellowish in color, the sori and indusia generally very slender. Tliis form is 

 often found strongly reduced in size, resembling Pteris Grevilleann. I have the 

 same form from Sikkim "Pteris aspericaulis Wall." leg. Dr. Jcrdon, and from 

 Cao Bang, Tonkin, leg. Dr. Billci, 1006.

Pteris cretica is exceedingly variable in the Philippines, I have not seen from 

 the Archipelago forms resembling those of Europe, but the above specimens 

 match closely P. stenophyUa, with 3 to several pinnae at the sumtnit of the 

 frond, more or less fan-Iike, the tips elongated. Texture normal, firm, shining, 

 light green.
