Codonopsis atriplicifolia Y. Yu & Q. Wang , sp. nov. Figs. 2A–F

Type:— CHINA. Sichuan, Baiyu, Chola mountains , rocky slope, 3300 m, 19 Jul 2020, Y. Yu et al. DS02 (holotype: SZ barcode 02042692!; isotypes: SZ barcodes 02042693!, 02042694!, 02042695!) .

Roots carrot-shaped, slender, 5–20 cm long, 0.3–0.5 cm in diameter. Stems erect, 50–120 cm tall, simple or branched below, sparsely pubescent to subglabrous. Leaves subrosulate, alternate; petiole 0.5–4 cm long, subglabrous; leaf blade linear-lanceolate, 3–15 cm long, 0.5–1.5 cm broad, adaxially green, sparsely hispidulous, abaxially gray-green, sparsely hispid along veins, base cuneate, margin subentire to pinnatipartite, apex obtuse. Flowers often solitary and terminal on main stem and branches. Calyx tube adnate to whole hypanthium, semiglobose, 10-ribbed, subglabrous; calyx lobes narrowly deltoid, 0.4–0.8 cm long, 0.2–0.3 mm broad, glabrous, margin entire, sometimes sparsely serrate, apex acute; sinus between lobes broad and truncate. Corolla broadly campanulate, 1–2 cm long, 1.5–2 cm wide, lobed to near one third, red-purple with dark purple veins, and white on apex of corolla lobe, glabrous on both sides with sparsely hispidulous margin. Stamens glabrous; filaments 0.3–0.5 cm long, slightly dilated at base; anthers ca. 3 mm long. Capsule semiglobose below, conical above. Seeds unknown.

Etymology:—From Latin, atriplici- ‘ Atriplex ’ + folia ‘leaf’. Meaning the species with leaves like those from the species of Atriplex Linnaeus (1753: 1052) , which is a genus that belongs to the family Amaranthaceae . In order to facilitate communication among local scholars, we suggest a Chinese name: bīnlíyè dǎngshēn (滨※叶党参).

Phenology:—Flowering from June to August; fruiting in September and October.

Habitat:—Rocky slopes at an altitude of ca. 3300 m.

Distribution:—Endemic to western Sichuan, China.
