Dryopteris villarii, commonly known as the Rigid Buckler Fern,[2] is a perennial leptosporangiate fern native to Central and South East Europe as well as the Western Caucasus. It was first described in 1915.[1]

Description

[edit]

Dryopteris villarii typically reaches heights around 30 to 60 cm.[3] The rigid, leathery fronds are of a matt glaucous to dark green colour, with scaly reddish petioles and rachis.[4][5] Fronds may present tufted, erect or spreading.[5] The short bipinnate leaflets are slightly dentate and narrowly oblong-lanceolate, attenuating closer to the base, with yellowish aromatic glands on either side.[3][4][5] Rhizomes are far creeping and adventitious, horizontal to ascending.[5] Sori between 0.7 mm to 1 mm, usually with glandular indusium and arranged in two rows along the midrib, usually four to six per row. They do not cover the apex.[3][4][5]

Distribution

[edit]

Dryopteris villarii appears within dolomite and limestone pavements, scree, cliffsides, rocky outcrops, scrub and non-alpine and non-saline grasslands.[5][6] It is found between 500 m to 2000 m.[4] It is tolerant of any soil type although prefers alkaline.[6]
