Arabis alpina, the Alpine rock-cress, is a

native to mountainous areas of Europe, North and East Africa, Central and Eastern Asia and parts of North America. In the British Isles, it is only known to occur in a few locations in the Cuillin Ridge
of the Isle of Skye. It inhabits damp gravels and screes, often over limestone.

Description

The stems grow up to 40 cm (16 inches) tall, and are topped with loose heads of white, four-petalled flowers. Flowers bloom in spring. The leaves in the basal rosette are long, strongly toothed and clearly stalked, although the stem leaves are stalkless and clasp the stem. It is a perennial herb.[1] The plant attracts butterflies.[2]

Taxonomy

Arabis alpina is believed to have originated in Asia Minor about 2 million years ago. From there it migrated twice into East Africa (500,000 years ago) where it grows today on the high East African mountains in the

periglacially. In genetic terms, the highest diversity is found in Asia Minor. In central and northern Europe, A. alpina seems to be genetically quite uniform.[3]

There is growing interest to develop Arabis alpina as a model organism for

QTL mapping
.

Subdivision

A former subspecies, A. alpina subsp. caucasica, is now recognised as a separate species, Arabis caucasica.
