About Koenigia davisiae (W.H.Brewer ex A.Gray) T.M.Schust. & Reveal
Koenigia davisiae is a deciduous perennial herb that grows a decumbent or upright stem from a woody caudex, reaching a maximum erect height of close to 40 centimeters. Stems can range in color from pale green to red. Its leaves are oval and pointed, widely lance-shaped, or somewhat triangular. They are yellowish or pale green, with a waxy texture that may be slightly hairy or smooth. Leaf margins are either entire or minutely toothed. A thin reddish sheath formed from the leaf's stipules, called an ochrea, is present at the base of each leaf. From late summer to autumn, the leaves change color to orange or red. Flowers grow in clusters of 2 to 5 in leaf axils. The flowers are yellowish, greenish, or purple-tinged, and are just a few millimeters wide.
Koenigia davisiae is native to the western United States, where it occurs in Washington, Oregon, and central and northern California (specifically the northern Coast Ranges and northern Sierra Nevada). Isolated populations of this species are also found in central Idaho. It grows in high mountain habitats including talus and fellfields.
