Ctenitis subglandulosa (Hance) Ching

Japanese: カツモウイノデ（英語表記）Ctenitis subglandulosa (Hance) Ching

An evergreen perennial fern of the Dryopteris family. It often forms a dominant community in chinquapin forests. The rhizome grows upright from an upward angle, and several large leaves grow in a clump. The leaves are pentagonal-ovate and 3-4 times pinnate. The central axis and rachis are covered with brown scales that are somewhat compressed, but those at the base of the petiole are long, linear, yellowish brown to reddish brown, and form a bushy bundle. This is where the Japanese name "Kuuhauino-de" comes from. The sporangia are small, located slightly toward the midrib of the lobe, and are surrounded by a finely lobed envelope. It occurs in warm areas west of the Kii Peninsula, and is close to subtropical elements, but is rare in areas with heavy rainfall.

Japanese:

オシダ科の常緑多年生シダ植物。しばしばシイ‐タブ林内に優占的な群落をつくる。根茎は斜上から直立し，大型の葉を数枚，叢生（そうせい）する。葉は五角状卵形で，3～4回羽状複生。中軸や羽軸には褐色の鱗片が圧着気味につくが，葉柄基部のものは線形で長く，黄褐色から赤褐色で，ふさふさとした束になる。これから褐毛イノデの和名が由来した。胞子囊群は小さく，裂片のやや中肋寄りにつき，辺縁が細裂した包膜につつまれる。紀伊半島以西の暖地に生じ，亜熱帯要素に近いが，多雨域には少ない。
