Ecology & Habitat

Description

Mat Buckwheat is a low, perennial herb or subshrub that forms cushions up to 5 cm high. The alternate, oblong leaves are 10-15 mm long, including the petiole, have entire, downturned margins, and persist on the stem after withering. The foliage is covered with long, gray hairs. The numerous flowers are borne in crowded, globose inflorescences atop leafless stalks that are 3-8 cm high. Flowers arise from a solitary, cup-shaped involucre with 6-7 reflexed lobes. Each flower has 6 yellow and rose, petal-like perianth segment that are 3-5 mm long. The perianth segments are united below and taper to a hairy woolly base.

Diagnostic Characteristics

The tapered, stalk-like perianth and the solitary involucre distinguish this species from other mat-forming ERIOGONUM.
