This is a graceful, rock-loving fern with long (to 48 in.), slender, recumbent, light-green fronds which taper to a point. Bulblets, which form on the undersides of the fronds, begin as microscopic dots, eventually growing to 1/2 in., by which time they are producing delicate young fronds of their own.
