Veronica laxa Benth. Scroph. Ind. 45. 1835 et In DC. Prodr. 10: 474. 1846;中国高等植物图鉴, 4: 42.图5497. 1975.——V. thunbergii A. Gray, Mem. Am. Acad. N. S. 6: 402. 1857——V. melissifolia auct. non. Poir. : Pennell, Monogr. Acad. Nat. Sci. Philad. 5: 86. 1943.
植株高（15）50-80厘米，全体被白色多细胞柔毛。茎直立或上升，不分枝。叶无柄或具极短的叶柄，叶片卵形或卵状三角形，长2-5厘米，宽1-3厘米，边缘具深刻的粗锯齿，多为重锯齿。总状花序单支或成对，侧生于茎中上部叶腋，长而花疏离，果期长达20厘米；苞片宽条形或倒披针形，长约5毫米；花梗比苞片短得多；花萼裂片条状长椭圆形，花期长4毫米，果期长5-6毫米；花冠辐状，紫色或蓝色，直径6-10毫米，裂片圆形至菱状卵形；雄蕊与花冠近等长。蒴果倒心形，长4-5毫米，宽5-6毫米，基部楔状浑圆，有多细胞睫毛，花柱长3-4毫米。种子南瓜子形，长略过1毫米。花期6月。2n＝46
分布于云南、四川、贵州、湖南、湖北及陕西和甘肃（东南部）。印度也有。生海拔1500-2500米的沟谷阴处或山坡林下。
该种以其比较高大的植株、长而疏生花的总状花序不同于本组其他种，仅仅与V. rchamaedrys较近，但两者又以茎上被毛方式、花柱长短、苞片与花梗比例而不同，且两者分布区也完全隔离。

Perennials, (15-)50-80 cm tall, entirely with white multicellular hairs. Stems erect or ascending, simple. Leaves sessile or short petiolate; leaf blade ovate to ovate-deltoid, 2-5 X 1-3 cm, margin coarsely dentate and mostly double dentate. Racemes 1 or 2, axillary from middle and upper leaves, lax, to 20 cm in fruit; bracts broadly linear to oblanceolate, ca. 5 mm. Pedicel much shorter than bract. Calyx 4-lobed; lobes linear-elliptic, subequal, ca. 4 mm at anthesis, 5-6 mm in fruit. Corolla purple to blue, rotate, 6-10 mm in diam.; tube less than 1.5 mm; throat hairy; lobes orbicular to rhomboid-ovate. Stamens almost as long as corolla. Capsule obcordate, strongly compressed, 4-6 X 5-6 mm, ciliate with multicellular hairs, base cuneate to rounded. Style 3-4 mm. Seeds 2-10 per locule, ovate, flattened, ca. 1 mm. Fl. Jun. 2n = 46.
Valleys, forest slopes; 1500-2500 m. SE Gansu, Guangxi, Guizhou, Hubei, Hunan, Shaanxi, Sichuan, Yunnan [India, Japan, Kashmir, Pakistan].
