Galium hypotrichium

Galium hypotrichium is a species of flowering plant in the coffee family known by the common name alpine bedstraw. It is native to the western United States, where it grows in mountain and plateau habitats, including parts of the Great Basin and Sierra Nevada in California, Nevada, and Utah.

Galium hypotrichium is a perennial herb forming mats from woody bases, sometimes taking dwarf form with stems just a few centimeters long. The stems have many whorls of four fleshy rounded or oval leaves. The inflorescences are made up of small protruding clusters of flowers scattered along the stems. The flowers may be white or tinged with yellow, green, pink, or red. It is dioecious, with male and female flowers on separate plants.
