Teucrium racemosum

Teucrium racemosum, the grey germander, is a slender perennial herb or subshrub of the Lamiaceae native to inland eastern and southern Australia, where it occurs on heavy clay floodplains, gilgai depressions, and seasonally inundated grassland. Plants arise from a slender, often rhizomatous rootstock and reach 20–60 cm, with quadrangular, finely white-tomentose stems that are slightly woody at the base. Leaves are opposite, sessile or short-petiolate, narrowly oblong to elliptic, 2–6 cm long and 4–10 mm wide, with entire to shallowly crenate margins, grey-green and finely tomentose on both surfaces, the lower side paler. Inflorescences are slender, terminal, elongate racemes 5–20 cm long with the flowers in distant, often opposite or whorled pairs subtended by small bracts. Each flower has a 5-toothed tubular calyx and a strongly zygomorphic white to pale-pink corolla 8–12 mm long; as in all Teucrium, the upper lip is essentially absent and the four stamens are exserted between the deeply divided upper lobes onto a prominent 5-lobed lower lip. The fruit is 4 small reticulate nutlets.
