Flowers in Sichuan and Yunnan are pale purple, while in Xizang they are yellow.

Perennials, to 1 m tall. Stems often several, cespitose, simple or apically branched, glabrous. Leaves alternate, sessile, narrowly elliptic to ovate-elliptic, 2-5 X 0.6-1.3 cm, glabrous, veins 3-5. Inflorescences spicate, terminal, with numerous crowded flowers, to 12 cm in fruit, axis and pedicels with sparse multicellular glandular hairs; bracts lanceolate. Pedicel short. Calyx with multicellular glandular hairs on both surfaces or only on inside; lobes linear-lanceolate, 5-7 X 1-2 mm. Corolla pale purple or yellow, 8-10 mm (excluding spur); spur 5-6 mm, slightly curved; lips equal in length; lower lip lobes ovate, ca. 2 mm wide, apex acute. Capsule globose, ca. 9 X 6 mm. Seed disclike, margin broadly winged, center verrucose. Fl. Jul-Sep.

W Sichuan, SE Xizang, NW Yunnan.

* Meadow slopes, forest margins, sparse thickets; 2500-3800 m.

Linaria yunnanensis W. W. Smith var. caerulea H. L. Li.

Flowering from July to September.

Linaria thibetica is close relative of Linaria yunnanensis, but differs from the latter in its calyx lobes linear-lanceolate (vs. lanceolate to narrowly ovate), corolla spur 5-6 mm (vs. 2-4 mm).

Linaria thibetica is occurring in W Sichuan, SE Xizang, NW Yunnan of China.

Perennials, up to 1 m tall. Stems often several, cespitose, simple or apically branched, glabrous. Leaves alternate, sessile, narrowly elliptic to ovate-elliptic, 3-6 cm long, 0.8-1.5 cm wide, glabrous, veins 3-5. Inflorescences spicate, terminal, with numerous crowded flowers, up to 14 cm in fruit, axis and pedicels with sparse multicellular glandular hairs; bracts lanceolate. Pedicel short. Calyx with multicellular glandular hairs on both surfaces or only on inside; lobes linear-lanceolate. Corolla pale purple or yellow; spur slightly curved; lips equal in length; lower lip lobes ovate, ca. 2 mm wide, apex acute. Capsule globose, ca. 10 mm long, 6 mm wide.
