Perennial or annual herbs, at least sometimes tuberous and stoloniferous, with simple hairs; leaves toothed, petiolate; inflorescence thyrsoid, with cymes up to 3(-4)-flowered, or racemoid; calyx 5-lobed, lobes subequal, often ± spinescent; corolla strongly 2-lipped, 4-5-lobed (1/3, 2/3), purple to white, posterior lip long, hooded; stamens not exserted from corolla, thecae weakly distinct; stigma-lobes slightly unequal; nutlets truncate or subtruncate at apex, glabrous or sometimes hairy. One to perhaps five spp., forests, hill slopes and wet sites, China, Taiwan, Japan. Matsumurella is often included in Galeobdolon or in Lamium. The three Chinese species, described under Galeobdolon, G. szechuaense C.Y. Wu, G. yangsoense Sun and G. kwangtungense C.Y. Wu, may be more closely related to Matsumurella than to Lamium (incl. Galeobdolon). Some authors include Matsumurella in Lamium.
