Tectaria (English name)

Japanese: ナナバケシダ（英語表記）Tectaria

An evergreen perennial fern of the Dryopteridaceae family. In the strict sense, Tectaria is the species T. decurrens (Pr.) Copel., found from Okinawa to New Guinea, but in horticulture it is sometimes used as a general term for the Tectaria genus. Tectaria in the strict sense is native to tropical and subtropical regions, and its leaves are polymorphic, ranging from simple to pinnate, from which the name Nanabakeshida (seven-leaved fern) comes. The surface often has yellow hawk's feather-like spots. The veins of the leaves are finely connected in a reticulate pattern, with irregular free veins.

オシダ科の常緑多年生シダ植物。狭義にはナナバケシダは沖縄からニューギニアにかけて分布する種T.decurrens (Pr.) Copel.をさすが，園芸的にはナナバケシダ属Tectariaの総称とされることもある。狭義のナナバケシダは熱帯から亜熱帯の原産で，葉は単葉から単羽状と多型で，七化羊歯（ななばけしだ）の名はこれに由来する。しばしば表面に黄色の鷹の羽状の斑（ふ）がはいる。葉脈は網状に細かく結合し，不規則な遊離脈がある。
