Botanical Name: :Aspidium spinulosum
Class: Polypodiopsida /
Common Name : Wood fern, Male fern,Shield fern,Buckler fern
Habitat :Aspidium spinulosum is a genus of about 250 species of ferns with distribution in the temperate Northern Hemisphere, with the highest species diversity in eastern Asia. Many of the species have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of fronds. The sori are round, with a peltate indusium. The stipes have prominent scales.
The Prickly-toothed Shield Fern is allied to the Male Shield Fern, but is not so tall, about 8 to 14 inches, and has very much broader leaves. The rootstock is similar to Male Fern, but there are differences in the number of wood bundles in the stems, also in the hairs on the margins of the leaf-stalk scales. The fronds are more divided – twice or thrice pinnate – and are spinous, the pinnae generally opposite and the lowest pair much shorter than the others. The sori are circular, with kidney-shaped indusium, much smaller than in Filix-mas.

The Prickly-toothed Shield Fern is moderately erect and firm and grows in masses, being common in sheltered places on moist banks and in open woods.
Dryopteris filix-mas was throughout much of recent human history widely used as a vermifuge, and was the only fern listed in the U.S. Pharmacopoeia.
The medicinal uses are as in Male Fern, with the rhizome of which, as imported from the Continent, it has always been much mixed.
Many Dryopteris species are widely used as garden ornamental plants, especially D. affinis, D. erythrosora and D. filix-mas, with numerous cultivars.
