490566F8EFB65F61991B5D21C3716FCB.taxon	diagnosis	Diagnosis. Similar to Tarenna tsangii, but distinguished by its small form, asymmetrical leaves, vegetative leaves larger than inflorescence leaves, blades adaxially pilosulous, pendulous inflorescences, longer pedicels (15 – 35 mm vs. 4 – 7 mm in T. tsangii), shorter corolla tubes (1 – 1.4 cm vs. 1.8 – 1.9 cm), multiple ovules per locule (vs. 2), and sparsely pubescent fruits with 13 – 19 seeds (vs. glabrous fruit containing only 4 seeds).	en	Qin, Yong-Hua, Bussmann, Rainer W., Liu, Zhi-Rong, Li, Man, Xia, Chang-Ying, Wu, Wang-Hui, Yu, Sheng-Xiang (2025): Tarenna pendula (Rubiaceae), a new species from Guangxi, China.

490566F8EFB65F61991B5D21C3716FCB.taxon	description	Description. Erect shrub up to 1 – 2 m tall, with a single main stem; branches flattened, shortly pilosulous, first year branchlets green, becoming brown or grayish-brown with age. Leaves opposite; petiole ca. 1 cm long, pilosulous; leaf blades asymmetrical, papery and blackish-brown when dried, oblong – obovate or oblanceolate, 4 – 17 cm × 1.5 – 4 cm, vegetative leaves large, 7 – 17 cm × 3 – 4 cm, inflorescence-supporting leaf pairs small, 4 – 7 cm × 1.5 – 3.5 cm, adaxially with adnate short hairs, abaxially scabrous and sparsely puberulent to subglabrous, with pubescence denser along principal veins, base cuneate, apex acuminate or shortly acuminate; midrib flat on upper surface, prominent on lower surface; secondary veins in 5 – 7 pairs, prominent on lower surface; stipules triangular, 3 – 5 mm, acuminate or apiculate when longer, persistent. Inflorescence corymbose, axillary or sometimes terminal, pendulous, 5 – 7 cm × ca. 3 cm, 3 - 5 - or sometimes 9 - flowered, shortly pedunculate, peduncles 3 – 8 mm, inflorescence axes and pedicels gray strigillose. Rachis unbranched. Flowers opposite on rachis, pedicels 1.5 – 3.5 cm long, proximal pedicels long, 2.5 – 3 cm long, distal pedicels short, 1.5 – 2 cm long. Calyx green, pilosulous; hypanthium portion cylindrical – urceolate, ca. 1 mm long; limb ca. 0.5 mm long, lobed for up to 1 / 2 of length. Corolla white, 1.5 – 1.9 cm long; tube cylindrical, ca. 5 mm long, inside at the upper part near the throat with dense hairs and at the lower part glabrous or sparsely pubescent, outside glabrous; lobes 5, contorted to the left in bud, oblong, 10 – 14 × 2 – 3 mm, with rounded apex, adaxial surface glabrous or sparsely pubescent at base, abaxial surface glabrous. Stamens inserted in corolla throat, alternating with corolla lobes, attached to the throat by a short filament; anthers yellowish-gray, linear, 8 – 10 mm long, basifixed, twisted after spreading. Style-stigma complex 1 – 1.2 cm long, exserted for 5 – 7 mm from corolla tube at anthesis; style sparsely pubescent at the middle; stigma fusiform, acentric apices. Ovary small, usually cup-shaped, 0.5 – 1 mm long, with 2 locules, each axile placenta with multiple ovules. Fruits berry-like, subglobose, 5 – 6 mm in diameter, with short persistent calyx teeth or calyx scar at the apex; seeds 13 – 19 per fruit, elliptic, 3 – 3.2 × 1.8 – 2 mm, brownish or black, testa rugose.	en	Qin, Yong-Hua, Bussmann, Rainer W., Liu, Zhi-Rong, Li, Man, Xia, Chang-Ying, Wu, Wang-Hui, Yu, Sheng-Xiang (2025): Tarenna pendula (Rubiaceae), a new species from Guangxi, China.

490566F8EFB65F61991B5D21C3716FCB.taxon	distribution	Distribution, habitat, and ecology. Tarenna pendula grows in southern subtropical evergreen broadleaf forests, particularly in mixed bamboo understory (Indosasa sinica C. D. Chu & C. S. Chao), at 1380 m a. s. l. The species is only known from this single locality in Napo County, Guangxi Autonomous Region, China (Fig. 3).	en	Qin, Yong-Hua, Bussmann, Rainer W., Liu, Zhi-Rong, Li, Man, Xia, Chang-Ying, Wu, Wang-Hui, Yu, Sheng-Xiang (2025): Tarenna pendula (Rubiaceae), a new species from Guangxi, China.

490566F8EFB65F61991B5D21C3716FCB.taxon	etymology	Etymology. The specific epithet is derived from the pendulous inflorescence, which differs from several other Tarenna spp. in the area.	en	Qin, Yong-Hua, Bussmann, Rainer W., Liu, Zhi-Rong, Li, Man, Xia, Chang-Ying, Wu, Wang-Hui, Yu, Sheng-Xiang (2025): Tarenna pendula (Rubiaceae), a new species from Guangxi, China.
