Crepis nana is a species of flowering plant in the daisy family
known by the common name dwarf alpine hawksbeard. It is native to much of northern North America and northern Asia, where it is a plant of the alpine climate
and maritime regions across the Arctic
. It grows in scree
, on gravelly sandbars and sandy, exposed snowmelt streambanks, and other disturbed, open habitat. It can be found on the Canadian Arctic Archipelago
and the islands of Alaska
. This is a dwarf perennial herb producing a low clump of purple-tinged green leaves on a stem just a few centimeters high. The hairless leaves are oval and sometimes have a few lobes along the edges. The inflorescence
has 2 to 4 flower heads
nestled close to the leaves and near the ground where the air is warmest. Each flower head has several yellow ray florets with a base of phyllaries
tipped with hairs.
