Bristlecone oreocarya is a rare (CNPS 1B.2) California native perennial found in the southern White and Inyo Mountains in rocky, dry meadows within open bristlecone pine-limber pine forest at elevations of 2,570 to 3,230 meters. Flowering from June to July, this plant produces pale yellow flowers with delicate white appendages in dense, head-like clusters. Growing with multiple spreading stems 1 to 3 centimeters tall that are soft and bristly, it forms numerous basal rosettes with distinctive gray-green leaves. Its leaves are oblanceolate to narrow spoon-shaped, densely covered in silky hairs with mostly appressed bristles that have bulbous bases. The fruit consists of 1 to 3 shiny dark gray nutlets, each 2 to 2.5 millimeters long with sharp-angled margins.
