Inflorescence of Veiny Dock, Winged Dock: Rumex venosusThe photo at right shows part of the inflorescence, which is a loose panicle. The outer floral parts as seen here are erect to spreading while the inner ones eventually become greatly enlarged, reddish, semi-orbicular and heart-shaped in fruit. Photographed about one mile east of Celilo, OR...........mid March, 2005.

Characteristics:

Veiny dock is a smooth-surfaced perennial with erect, branched stems arising 15-50 cm high from a spreading, woody rootstock. The stems are often reddish, with numerous thick, leathery leaves (no basal leaves). The leaf blades are oblong-elliiptic to broadly lanceolate or oblong-oblanceolate, from 6-12 cm long, tapering to short petioles. The stipules are white, very conspicuous, from 1-3 cm in length.

The inflorescence is a loose, leafy panicle of small flowers, each measuring 4-5 mm long.


Habitat:

Veiny dock is found on sandy or gravelly soils, including those found along riverbanks, in deserts, and occasionally in looser soils in the grasslands and the sagebrush desert.


Range:

Veiny dock may be found entirely east of the Cascade Mts. from southern British Columbia south to northeastern California, and east to Saskatchewan, North and South Dakota, Nebraska, Colorado, and New Mexico.

In the Columbia River Gorge, it may be found between the elevations of 100-500' east of Mosier, OR.
