Distribution and habitat

This orophyte species occurs in central and southern Europe and western Asia, in rocky lawns, limestone hills and mountains of Pyrenees, Alps, Apennines, Rhodope Mountains and Urals, at an elevation of 1400m-2500mm (4,600feet-8,200feetm) above sea level.[2]

Description

Linum alpinum has stems erect or recumbent, densely leafed, reaching an average of 10cm-50cmcm (00inches-20inchescm) in height. This plant is glabrous and woody at the base. It has alternate leaves that are linear-lanceolate, up to 2.5cm (01inches) long, and sessile. The hermaphrodite, rather large flowers with radial symmetry are blue, yellow at the bottom, with a diameter of 2cm-3cmcm (01inches-01inchescm) and with erect or slightly inclined pedicels, in loose clusters each containing one to eight flowers. Sepals are unequal, with three veins at the base, 5–7 mm long. The petals are 12–20 mm long, three-four times longer than sepals. The fruits are capsules 6–8 mm long. Each fruit compartment contains a blackish seed.[2] [3] This species is quite similar to Linum leonii and Linum ockendonii.[4]

Biology

This perennial plant blooms from May to August.[2] The flowers are bent before flowering, where as floral peduncles remain erect after flowering. Typical pollinators are insects (bees, bumblebees, wasps, hoverflies, etc.).
