Oreocarya virginensis (Virgin river oreocarya) is a native California herb in the Boraginaceae family, recognized by fragrant flowers, large folded leaves, non-woody caudex diagnostic.
Virgin river oreocarya is a California native perennial found in the eastern Sierra Nevada and Mojave Desert bioregions on loose limestone soils at elevations of 840 to 2,450 meters. Flowering from April to June, this plant produces scented white or yellow flowers with a limb 7 to 10 millimeters in diameter. Growing 10 to 40 centimeters tall with multiple stems covered in dense, spreading yellow bristles, it forms a single basal rosette of thick, gray-green leaves. Its leaves are 5 to 12 centimeters long, oblanceolate to spoon-shaped, densely strigose with sparse spreading bristles. The fruit consists of 1 or 2 gray to tan nutlets 3.3 to 4.5 millimeters long with irregular wrinkles and a sharp-angled margin.

How to tell it apart
vs Cryptantha: Cryptanthas are slender annuals with tiny inconspicuous white flowers; Oreocarya are stout perennials from a woody branched caudex with showier, densely clustered white or yellow flowers.; vs Hackelia: Stickseed nutlets bear hooked marginal prickles that cling to clothing; Oreocarya nutlets are smooth to roughened but lack hooked prickles.; vs Plagiobothrys: Popcornflowers are annuals of moist ground, often red-staining, in open coils; Oreocarya are harsh, bristly perennials forming cushions on dry rocky or desert sites.; vs Cynoglossum: Hound's-tongue is a tall, leafy-stemmed biennial with broad soft leaves and reddish-blue flowers; Oreocarya is low and cushion-like with narrow bristly leaves and white or yellow flowers.; vs Cryptantha: Beyond size, Oreocarya has persistent basal rosettes and a woody caudex, whereas Cryptantha germinates fresh each year with no woody base.
