[Docks and Sorrels: The Genus Rumex in the Columbia River
Gorge of Oregon and Washington]
Veiny Dock, Winged Dock
Rumex venosus
Veiny dock growing on a large sand dune in the southern Goodnoe Hills of south-central Klickitat County, WA.......April 20, 2011.
The
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.
The photo above shows a stem leaf and stipules
of veiny dock as seen east of Celilo, OR.......mid March, 2005. The leaf
is very thick and stiff, and bears numerous veins as seen here.
