Description

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

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]
