Notes:— Teucrium chowii is a rare species endemic to Guizhou Province, China. This species is used as a traditional Chinese medicine to treat sword wounds and stop bleeding by the local people (Chen et al. 2000). Chow (1965) assigned it to Teucrium sect. Pleurobotrys Hemsley (1890: 311) , for it has 2-flowered verticillasters, conspicuously 2- lipped calyx with pilose annulate throat, and stamens twice as long as corolla tube. Teucrium chowii is closely related to T. bidentatum Hemsley (1890: 312) , but the former has subsessile leaves with entire margin and longer corolla (1.2 cm) with hairy lip center, while the latter has petioles 5–9 mm long, leaf blade margin of apical half 3–4-serrate and shorter corolla (1 cm) with glabrous lip center ( Chow 1965).
