|
---|---|---|
cushion buckwheat, oval-leaved eriogonum |
||
Habit | Mat-forming perennial that is highly variable in leaf shape, pubescence, length of flowering stem and flower color. | |
Leaves | All basal, white-woolly on both surfaces to somewhat green on the upper surface, spatulate (less than 1 cm. long, without a petiole) to elliptic to rhombic to oblanceolate, the blades 5-20 mm. long and 3-15 mm. broad on petioles 1-3 times as long as the blades. In Washington, it is primarily a sub-alpine species, with white-woolly leaves about 1.5 cm. long and broadly elliptic. |
|
Flowers | The inflorescence is a capitate cluster of several involucres, 1-3.5 cm. broad, subtended by 3 or more narrow bracts, on leafless stems 3-20 cm. tall. Involucres narrowly cup-shaped, 3-5 mm. long, with 5 lanceolate, erect teeth; tepals usually cream to rosy-pink, the segments free nearly to the base, which is not stipe-like, the outer ones oblong and nearly twice as wide as the inner segments. |

Eriogonum ovalifolium |
|
Identification notes | The tight, ball-like inflorescence on a naked, unbranched or minimally branched stem usually will separate E. ovalifolium from the similar E. strictum. If the color is bright pink to rose-red, it is E. ovalifolium, not E. strictum. | |
Flowering time | May-August | |
Habitat | Sagebrush deserts, juniper and ponderosa pine forests, to alpine ridges. | |
Distribution | Occurring on both sides of the Cascades crest in Washington; British Columbia to California, east to the Rocky Mountains.
