The "Hakata-shida" (Arachniodes simplicior) belongs to the family Dryopteridaceae. It is an evergreen fern that is distributed from Fukushima Prefecture of Honshu west to Shikoku, Kyushu in Japan and China. It grows in the forests of mountainous areas and is 50 to 100 cm tall. The leaves are dark green, glossy, and stiff, with a bipinnate compound structure. The petiole is 20 to 65 cm long. There are 3 to 5 pairs of pinnae, with a distinct terminal pinna. The sorus is located halfway between the edge of the lobes and the midrib, and the bract is brown to dark brown and reniform. The Japanese name comes from the fact that the leaves have vertical stripes, similar to Hakata textiles. In Chinese, it is called "長尾複葉耳蕨" (chang wei fu ye er jue).
