0BE63CBF2ADC54F58B05236C5AF00F27.taxon	diagnosis	Diagnosis. Stachys yingzuijieensis is most closely related to S. arrecta, but differs in its lamina oblong to elliptic-lanceolate (vs. cordate) with margin crenulate (vs. coarsely serrate), corolla white (vs. pink with purple spots) with tube included in calyx (vs. exerted from calyx) and nutlet surface smooth (vs. verrucate). Herbs perennial. Rhizomes white, densely glandular pubescent. Stems erect, simple, 50 - 75 cm long, quadrangular, densely villous and glandular pubescent. Leaves opposite; petioles 2 - 4 cm long, densely villous and glandular pubescent; lamina oblong to oblong-lanceolate, papery, 10 - 16 x 4 - 6 cm, apex acute, margin crenulate, base cordate, adaxially green, sparsely villous and glandular pubescent, abaxially light green, densely villous and glandular pubescent, lateral veins 4 - 5 - paired, conspicuously elevated abaxially. Verticillasters 6 - flowered, flowers sessile; bracts leaf-like, upper ones sessile, lanceolate, densely villous and glandular pubescent on both surfaces, longer than verticillasters; bracteoles linear, 1 - 2 mm long. Calyx campanulate, ca. 7 mm long, 10 - veined, densely villous and glandular pubescent outside, glandular pubescent inside, fruiting calyx dilated, ca. 9 mm long; teeth 5, subequal, ovate-lanceolate, ca. 3 mm long, apex spinescent. Corolla white, ca. 1 cm long, tube ca. 7 mm long, ca. 1.5 mm wide, pubescent annulate inside at 1 / 3 distance from base; 2 - lipped, upper lip erect, concave, subcircular, ca. 3 mm in diam., densely pubescent and glandular pubescent outside, glabrous inside, lower lip spreading, sparsely pubescent and glandular pubescent to glabrescent outside, glabrous inside, ca. 6 mm long, 3 - lobed, medium lob largest, trapeziform, ca. 3 mm long, ca. 4 mm wide, apex entire or emarginate, lateral lobs oblong, ca. 2 mm long, ca. 1 mm wide. Stamens 4, straight, included, filaments pubescent and glandular pubescent, anther cells 2, divergent. Style included, glabrous, apex subequally 2 - lobed, lobes subulate. Ovary rounded at apex, glabrous. Nutlets 4, dark brown, ovoid, ca. 1.5 mm in diam., smooth and glabrous.	en	Xue, Ling, Cai, Jia-Hua, Zhan, Min, Li, Xiao-Ping, Wu, Lei, Chen, Ya-Ping (2023): Molecular and morphological evidence for a new species of Stachys (Lamiaceae) from Hunan, China.

0BE63CBF2ADC54F58B05236C5AF00F27.taxon	distribution	Distribution and habitat. Currently, S. yingzuijieensis is only known from the Yingzhuijie National Nature Reserve and a total of 50 mature plants were found during our field investigation. The new species usually grows in shady and moist places in evergreen broad-leaved forests at an altitude of 300 - 800 m.	en	Xue, Ling, Cai, Jia-Hua, Zhan, Min, Li, Xiao-Ping, Wu, Lei, Chen, Ya-Ping (2023): Molecular and morphological evidence for a new species of Stachys (Lamiaceae) from Hunan, China.
