Athyrium Roth (Woodsiaceae) Earlier placement: Athyriaceae, Dryopteridaceae

Lady fern

Etymology Greek: From athyrium meaning a small door. The indusium is hinged on one side. Description Rhizome: short-creeping or erect. Frond: deciduous, monomorphic. Stipe: deeply grooved above, swollen at base, scaly, vascular bundles: 2, lunate, uniting to a U-shape above. Blade: 2-pinnate-pinnatifid, linear to bradly triangular, herbaceous, below: absent or of linear to lanceolate scales or 1-celled glands. costae V-grooved above, continuous from rachis to costae, segments serrate or crenate, veins veins free, simple or forked. Sori: linear or oblong or j-shaped (round), in 1 row between midrib and margin, indusium: shape of sori (absent), sinus, sporangia: brownish. Distinctive Characteristics Dichotomous keys are unsuccessful in keying out this genus, i.e., it is poorly circumscribed. In the main it is closest to Deparia and Diplazium, sharing with them 2 vascular bundles and rachis/costa grooves on the upper side. These two genera and most Athyrium have elongate sori. It is separated from Deparia by deeper grooves and continuity

근경 직립 또는 비스듬히 서고 잎이 총생한다

엽병: 길이 20-40cm, 기부에는 흑갈색의 인편이 붙는다. 인편은 선형이고 가장자리가 밋밋하다.

엽신: 30-50cm, 2회우상복엽이다. 타원형 또는 삼각상 난형으로 상부가 갑자기 좁아지고 엽질은 초질이다. 우편은 짧은 자루가 있고, 하부 우편의 자루는 1cm에 달한다. 소우편은 중열-천열하고 맨 밑에 있는 열편은 특히 커서 귀 모양으로 나오며, 우축을 덮는다.

포자낭군: 중륵 가까이에 2줄로 배열하고 포막은 타원형이며 등을 맞댄 것도 간혹 섞인다,
