Herbs, perennial, erect to somewhat climbing, with woody rootstock; stems 0.5 m or more, clustered, quadrangular, angles ± retrorsely aculeolate. Leaves in whorls of up to 6-8(-10), narrowly linear, 20-50 × 0.5-1 mm, base acute, margins revolute and antrorsely aculeolate, otherwise glabrous and smooth, single vein forming a thick midrib ca. 1/2 of leaf breadth, apex acute, with hyaline point. Inflorescence thyrsoid, with lax, few-flowered axillary and terminal cymes; bracts filiform; pedicels ca. 5 mm. Ovary ca. 0.5 mm, glabrous. Corolla dark red (perhaps sometimes ?white), rotate, 3-4 mm in diam., glabrous; lobes triangular, 3-veined, abruptly caudate with acumen ca. 1 mm. Mericarp berry black, 3-4 mm in diam. Fl. summer-early autumn, fr. late autumn-early winter.
● Dry and rocky meadows; 3000-3800 m. Sichuan, NW Yunnan.
Together with Rubia angustissima Wallich ex G. Don and R. charifolia Wallich ex G. Don from the Himalaya, both with greenish-yellowish flowers, the dark-red flowering R. haematantha forms an aberrant, closely related species assembly, provisionally called R. angustissima group. It occurs from the W Himalaya (Kashmir) to Nepal, Myanmar, Bhutan, and SW China. The group shares retrorsely aculeate stems, linear to filiform leaves in whorls of up to 8(-10), and caudate corolla lobes. Species delimitation within this group is still provisional. Whereas Deb and Malick (Bull. Bot. Surv. India 10(1): 5. 1968) unite R. angustissima and R. charifolia ("R. charaefolia"), the two taxa are maintained by Long (Fl. Bhutan 2(2): 823-825. 1999). The reliability of the flower color as differential character of R. haematantha also needs further study. If only one species is accepted, its name would have to be R. angustissima.Together with Rubia angustissima Wallich ex G. Don and R. charifolia Wallich ex G.
