Perennials or subshrubs; (caudex well-developed, woody); not scapose; (glaucous), glabrous. Stems (simple or few to several from base), erect or ascending, usually branched distally. Leaves cauline; not rosulate, petiolate, subsessile, or sessile, blade (somewhat fleshy, becoming leathery when dry, base not auriculate), margins entire, denticulate, or coarsely dentate. Racemes (corymbose, few- to several-flowered, sometimes bracteate proximally), elongated in fruit. Fruiting pedicels divaricate to ascending or suberect, slender. Flowers: sepals ascending to erect, oblong, lateral pair usually not saccate basally (slightly saccate in H. linearifolius, apex of median pair cucullate or not); petals white, lilac, lavender, purple, or yellow (sometimes with darker veins), spatulate, claw differentiated or not from blade; stamens tetradynamous or subequal; filaments not dilated basally; anthers oblong to linear, (apex obtuse or apiculate); nectar glands: lateral annular or lunar, median glands often confluent with lateral. Fruits sessile or stipitate, linear, not torulose, terete or slightly latiseptate; valves each with prominent midvein; replum rounded; septum complete; ovules 8–110 per ovary; style distinct; stigma capitate or conical, entire or 2-lobed (lobes prominent, connivent).

Discussion
Species 5 (5 in the flora).
For a detailed account on the generic limits and affinities of Hesperidanthus, see I. A. Al-Shehbaz (2005). As delimited here, the genus includes what R. C. Rollins (1993) assigned to Schoenocrambe Greene (minus the type), Caulostramina, and Glaucocarpum. One species is endemic to Inyo County, California, three are highly localized endemics in Utah, and the fifth is widespread in the southwestern United States and northern Mexico.
