Stems wiry to woody, hairy with mainly long fine simple hairs, and some forked or rarely stalked stellate hairs (needs a hand lens or a macro app on your phone/tablet to see). Leaves alternating along the stems, 0.28–0.86 cm long, less than 1 mm wide, upper surface sparsely simple hairy with mixed longer and shorter hairs when young, becoming warty later, lower surface sometimes visible between the scarcely raised central vein and the rolled down margins. Tufts of hairs, often forked or rarely stellate hairs, at the bases of the leaves, continued along the grooves on the sides of the leaf bases (which continue down the stems). Flowers with 5 yellow petals each 6.6-8.3 mm or more long. Stamens 13-15, on one side of the carpels. Carpels 2, hairy with erect to appressed hairs. Flowers single, stalkless, at the ends of the stems. Flowers mainly spring.
