Halimolobos jaegeri (Jaeger's halimolobos) is a native California subshrub in the Brassicaceae family, recognized by Only Halimolobos species in California, Great Basin endemic with limited California range.
Jaeger's halimolobos is a California native perennial found in western Inyo and eastern Mojave Desert regions on limestone cliffs, steep rock outcrops, and sagebrush-juniper areas at elevations of 1,200 to 2,600 meters. Flowering from May to September, this plant produces small white petals 4.5 to 6 millimeters long with delicate, narrow form. Growing with many-branched stems 15 to 75 centimeters tall that are somewhat woody at the base and densely hairy, it develops a moderately robust structure. Its leaves are oblanceolate to obovate, 3 to 8 centimeters long with coarsely dentate margins and dense hair coverage, becoming progressively smaller up the stem. The fruit develops as a narrow cylindric pod 1.5 to 2.6 centimeters long, densely covered in fine hairs with seeds arranged in a single row.
