Saxifraga rivularis is a species of saxifrage known by several common names, including highland saxifrage,[1] weak saxifrage,[2] alpine brook saxifrage, and pygmy saxifrage.
Distribution
Saxifraga rivularis is native to the northern parts of the Northern Hemisphere, where it has a circumpolar distribution, occurring throughout the Arctic and into the alpine climates of mountainous temperate areas, such as the Sierra Nevada in California . It also occurs in the Highlands of Scotland, from which it takes its name, however it is very rare in this area.[3] It can be found in moist and wet, rocky habitat, in substrates rich in nitrogen and organic material, such as bird rocks and mossy peat flats.[4]
Description
Saxifraga rivularis is a small perennial herb growing not much more than 12 centimeters in maximum height. It has small, lobed leaves at the base and along the stem. Basal leaves are between 5-20mm in length, and petioles are substantially longer than the blade.[5] The inflorescence arises on a hairy, erect peduncle bearing white-petaled flowers and reproductive bulbils.
