Long'S Northern Rockcress (Braya longii)
Description
Long-s Braya is a small scapous (flower-stalk grows directly from the ground) perennial, with basal leaves that are fleshy and greyish-green to bluish in colour.It stands erect at a height of 1-10 cm. It is an obligate calciphile, meaning that it requires calcium-rich soil, and grows in limestone substrate disturbed by either natural (frost heave, wind or water erosion) or anthropogenic processes. The plant has a deep taproot for anchorage and moisture access, and dies back to the crown in winter.The flowers are each connected to a central scape on stems often with a single leaf, and, like all members of the mustard family, each flower has four tall and two short stamens. White, four-petaled flowers, each with four oval, green to purple-tinged sepals arranged in a raceme,have claws that are usually tinged with bluish- or reddish-violet. Leaves are linear-spatulate,with pointed ends, and measure 1-4 cm in length, 1-3 mm in width.
