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. This form is 
often found strongly reduced in size, resembling Pteris Grevilleana. I have the 
same form from Sikkim “Pteris aspericaulis Wall.” leg. Dr. Jerdon, and from 
Gao Bang, Tonkin, leg. Dr. Billet, 1906.

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. stenophylla, with 3 to several pinnae at the summit of the 
frond, more or less fan-like, the tips elongated. Texture normal, firm, shining, 
light green.
