Inflorescence condensed, with 6-flowered verticils touching in flower and up to 10 mm apart in fruit; bracts linear, 3 mm long, erect above forming an inconspicuous terminal coma, soon deciduous, the scar developing into a bowlshaped nectary; pedicels 2 mm long, ascending, slightly flattened

O. canescens differs from O. obovatum var. obovatum by the virgate stems and smaller broader, densely pubescent petiolate leaves and from var. galpinii by the smaller leaves and subshrub habit. These characters may be an adaption to withstand grazing.
