Festuca edlundiae, commonly known as Edlund's fescue, is a native, perennial, tufted grass of the High Arctic. It occurs in Alaska, the Canadian Arctic Archipelago, northern Greenland, far eastern Arctic Russia, and Svalbard.[1] The specific epithet honours Canadian botanist Sylvia Edlund. The species was first formally described in 1995 by Susan Aiken, Laurie Consaul, and Leonard Lefkovitch.[2]
Description
Festuca edlundiae is closely related to Festuca brachyphylla and resembles boreal fescue (Festuca hyperborea). It differs in having longer flag-leaf blades (5 mm or more) and larger spikelets. Plants form dense clumps and lack rhizomes.[3]
Habitat
F. edlundiae grows in High Arctic environments, typically on fine-grained or calcareous soils. It is well adapted to cold, short-season conditions and occurs in tundra habitats where few grasses can survive.
