Galium serpenticum is a species of flowering plant in the coffee family (Rubiaceae) known by the common name intermountain bedstraw or many-flowered bedstraw.

Range

Galium serpenticum is native to the northwestern United States , where it grows in dry mountain forests and meadows, mostly east of the crest of the Cascade Range. It occurs in Washington (state) , Oregon, Idaho and extreme northern California (Trinity, Siskiyou and Modoc Counties).[1][2] In the Wenatchee Mountains it is sometimes found on serpentine soils.[3]

Description

Galium serpenticum is a perennial herb forming tufts of erect stems up to about 30 centimeters tall with woody bases. The stems are ringed with whorls of four lance-shaped leaves and topped with inflorescences made up of clusters of small pale yellow to whitish flowers.[4][5] It is dioecious, with male and female flowers on separate plants.[6] Male and female flowers both have 4 small pale yellow to yellow-green petals, and female flowers have a prominent tuft of long spreading hairs protruding beneath the petals.[5]
