Racemes 1-4 pairs, axillary from upper leaves, lax, 2-7-flowered, 3-6 cm, axis and pedicels villous; peduncle 0.5-1.5 cm; bracts linear-lanceolate, shorter than pedicel, glabrous. Pedicel straight, 1-2 mm at anthesis, ca. 3 mm in fruit. Calyx 4-lobed; lobes linear-lanceolate, subequal, 3-4 mm at anthesis, elongated in fruit, glabrous. Corolla white or pale red, purple striate, rotate, ca. 1 cm in diam.; tube less than 1.5 mm; throat hairy. Stamens slightly shorter than corolla. Capsule pliciform-rhomboid, strongly compressed, 4-5 X 9-11 mm, base subtruncate or at an angle greater than 120°, margin apically sparsely ciliate with multicellular glandular hairs, emarginate.

Veronica henryi has been confused with V. cana, but they are distinct and no intermediates have been found. The relationship between V. henryi and V. riae is not completely understood, and V. henryi may be conspecific with V. riae.
