2EC807E5DA735213A76F7D8CF06E67A5.taxon	description	Description. Shrub erect, up to 2 m tall. Stems cylindrical, branched. Branches solid with white pith. Petiole 1.5 – 2.5 cm long, inconspicuously pubescent. Leaves opposite, leaf blade narrowly lanceolate, stiffly papery, 2 – 4 cm × 0.5 – 0.8 cm, hairy, narrow, margin with irregular undulations, entire, apex tapering. Inflorescence thyrsoid, axillary, cymes opposite and reduced to paired flowers, pedunculate with a pair of bracts and 2 pairs of bracteoles; bracts long, ca. 4.5 mm × 0.5 mm, bracteoles wide and short, ca. 0.5 mm × 0.5 mm. Paired flowers with free ovaries. Pedicels 1.5 – 2.5 cm long, Calyx 5 - lobed, with sparse glandular hair. Corolla bilabiate, yellow-green at the beginning, turns into reddish-purple after anthesis, ca. 1.4 × 0.5 cm; tube shallowly to deeply gibbous toward base, outside sparsely spreading hairy, inside puberulent; lower lip slightly recurved; upper lip 4 - lobed to middle. Stamens subequaling corolla, filaments pubescent. Ovary inferior, locules 2; style ca. 1.1 cm long, slender, hairy; stigmas capitate. Fruit a berry, round, green, turns red when mature, ca. 0.6 cm in diameter. L. lanzhouensis is morphologically most similar to L. webbiana and can be readily distinguished from it by having narrow leaves, yellow-green flowers at the beginning and reddish-purple when mature, and long involucrate bracts. In contrast, L. webbiana has ovate-elliptic to ovate-lanceolate leaves, red flowers and short involucrate bracts.	en	Liu, Shun, Wang, Yu-Jin (2025): Lonicera lanzhouensis (Caprifoliaceae), a new species from Gansu, Northwest China.
