Corolla red, purple-red, or dark purple, 4-5 mm; tube as long as limb; limb actinomorphic; upper lobes ovate-orbicular, lower lobes lanceolate. Stamens slightly exserted; filaments hairy. Capsule ovoid to ovoid-globose, 2-3.5 mm. Fl. Aug-Nov.

* Valley meadows, sparse forests; below 2000 m. Guangdong, Guangxi, Guizhou (Xingren Xian), SW Hubei, Hunan, Jiangxi, SE Yunnan.

Used medicinally to treat dysentery and sore throat.

One specimen from Pingshan, Sichuan (T. T. Yü 4333) belongs to Veronicastrum caulopterum but differs in having thin stems prostate basally, petioles ca. 1 cm, short and lax inflorescences, and pedicel ca. 2 mm. Furthermore, it is a distant disjunct from the main area and seems to merit subspecific rank. However, the material is inadequate for a proper taxonomic treatment.
