Silene bernardina is a species of flowering plant in the family Caryophyllaceae known by the common name Palmer's catchfly.[1]

It is native to western North America.

Description

Silene bernardina is a variable plant and is divided into several subspecies. In general, it is a perennial herb growing from a taproot and leafy caudex unit, the hairy, erect stems growing up to about .5 metres (1 12 feet) tall. The slender stems have glandular, sticky patches on their upper parts. The linear or lance-shaped leaves are up to 8 centimetres (3 inches) long low on the stem and smaller on the distal branches.

Flowers occur in a terminal cyme at the top of the stem, as well as in some of the leaf axils. Each has a hairy, glandular calyx of fused sepals with ten red veins. The calyx is open at the top, revealing five white or purple-pink petals which may be almost 3 cm (1 14 in) long. The petals have usually four fringelike lobes at the tips and feathery appendages at their bases. The stamens and three or four long styles protrude from the flower's center.

Distribution and habitat

It is native to western North America from Washington (state) and Idaho, through California and Oregon, to Baja California. It grows in several types of habitat, including chaparral scrub, mountain forests, and higher-elevation habitats in alpine climates.
