Sphaeralcea munroana is a relatively uncommon species, found at medium elevations in the northern Great Basin Desert and adjoining areas. The leaves often provide the best means of identifying globemallows; this species has leaves that are broadly triangular, with curved bases and rounded tips, prominent veins and large, coarse teeth along the edges. Older leaves may be weakly lobed. Stems, calyces and leaves (especially the undersurfaces) are canescent, covered by very fine, white, star-shaped hairs.
Flowers form in an elongated cluster along the top few inches of the stem, attached by short pedicels (shorter than the calyces). The five petals are about half an inch long; red to orange, light green at the base, arranged around a group of pale yellow filaments topped by yellow anthers. Flowers are supported by a green calyx that opens to five lobes, fused for about half their length.
