Tliis is an accentuated variation of the normal form, the length of the merely 
lobed apex and the pinnse, scarcely coarsely crenate, giving the plant a singular 
aspect.

Apparently common and widely distributed in the I'lulippines; endeinic.

Archipelago), that it should be recognized as a subspecies. A small plant, almost 
turf forming with elongated, weak and often running rhizomes, the fronds not, 
or but little dimorphous, the pinnae few, short, broad, nearly square and very 
irregularly lobed, the lobes sometimes short and obtuse, sometimes greatly 
elongated. The specimens with the elongated pointed pinn* have the appearance
