Laphamia megalocephala var. megalocephala (Nevada rock daisy) is a native California subshrub in the Asteraceae family, recognized by larger variety with broader leaves.
Nevada rock daisy is a California native shrub found in the White and Inyo Mountains on talus slopes, bare rocky outcrops, and cliffs in pinyon and juniper woodland and bristlecone-pine forest at elevations of 1,400 to 3,000 meters. Flowering from June to November, this plant produces white flowers in compact heads about 5 to 6 millimeters in diameter. Growing 30 to 60 centimeters tall with a robust, spreading form, it develops multiple stems that create a distinctive shrubby appearance. Its leaves are numerous, lance-ovate to rounded, measuring 7 to 15 millimeters long and 4 to 9 millimeters wide, creating a dense foliage structure. The plant notably lacks a pappus bristle, which distinguishes it from many other daisy-like mountain species.
