Arthropteris orientalis humblotii

Description

Dryopteris, commonly called wood fern, male fern (referring in particular to Dryopteris filix-mas), or buckler fern, is a genus of about 250 species of ferns with distribution in Eastern Asia, the Americas, Europe, Africa, and the Pacific islands, 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. Hybridisation is a well-known phenomenon within this group, with many species formed by this method. They have a short rhizome, robust, oblique, pale; palea broad, with the entire margin, sometimes with marginal glands. Densely fasciculated fronds; blade 1-4 pinnate, with symmetrical pinnacles, glabrous or glandulosa, with free rib. Soros usually orbicular; indusio reniforme. Monoecious, ellipsoidal spores.Hybridization is a well-known phenomenon within the group, with many species formed by hybridization.
