Veronica tibetica Hong, sp. nov. , in Addenda 404.
多年生草本，植株高约10厘米，具横走的根状茎。根须状，粗壮，直径达1毫米。茎数支丛生，上升，不分枝，密被白色多细胞长柔毛。叶多对，下部的较密集，花期枯萎，绿叶3-4对，具长5-7毫米的柄，上部叶的柄较短，叶片三角状卵圆形至卵形，长1-2厘米，宽1-1.5厘米，上部的叶较大，薄纸质，顶端钝至急尖，网脉明显，两面相当密地被白色多细胞长柔毛，边缘具5-7枚深刻而常钝的锯齿。总状花序1-2支，侧生于茎顶端叶腋，看起来象顶生，花期长2-3厘米，总梗长1厘米，花序轴及花梗被多细胞腺毛；苞片条状椭圆形，长于花梗，稍有毛；花梗花期长2毫米；花萼裂片4枚，长椭圆形，疏生睫毛，长3-4毫米；花冠白色，辐状，直径11毫米，喉部无毛，前方裂片倒卵形，其余3枚圆形；雄蕊略短于花冠；子房及幼果强烈侧扁，上缘有睫毛，花柱长3.5毫米。花期6月。
产我国西藏南部（吉隆）。生海拔2500米的河谷林下。
未见果实，但花萼4深裂，花冠辐状，子房及幼果扁平而上缘有睫毛以及总状花序侧生而花疏离，显示这个新种是属于疏花组的。由内面无毛的花冠、丛生而矮小的体态、茎下部具多对在花期枯萎的叶子、较短而粗壮的根状茎和粗壮的须状根看来，它是一个颇独特的种。

Perennials, ca. 10 cm tall. Roots thick, to 1 mm in diam. Rhizomes horizontal. Stems several, cespitose, ascending, simple, densely villous with white multicellular hairs. Leaves basally crowded, withered at anthesis; middle and upper leaves 3 or 4 pairs and larger upward; petiole 5-7 mm, shorter on lower leaves; leaf blade deltoid-ovate to ovate, 1-2 X 1-1.5 cm, papery, densely villous with white multicellular hairs, margin deeply incised with 5-7 and often obtuse teeth on each side, apex obtuse to acute, veins conspicuously reticulate. Racemes 1 or 2, axillary from uppermost leaves, appearing terminal, 2-3 cm in flower, axis and pedicels with multicellular glandular hairs; peduncle ca. 1 cm; bracts linear-elliptic, longer than pedicel, very sparsely hairy. Pedicel ca. 2 mm at anthesis. Calyx 4-lobed; lobes narrowly elliptic, 3-4 mm, subequal, sparsely ciliate. Corolla white, rotate, ca. 1.1 cm in diam.; tube less than 1.5 mm, glabrous in throat; lower lobe obovate, other 3 lobes orbicular. Stamens slightly shorter than corolla.
