Sinocrassula ganluoensis R.J.Li, J.G.Wang & J.Zhao sp. nov. ( Fig. 2 View FIGURE 2 , 3 View FIGURE 3 ).

Type.— China. Sichuan: Ganluo County, Liangshan Yi Autonomous Prefecture , elev. ca. 863 m, 29.095453 N, 102.835810 E, on the granite crevices, 5 July 2023, Jing Zhao et al. YUS-6699 (holotype YUKU!; isotype YUKU!) GoogleMaps .

Diagnosis. Sinocrassula ganluoensis is similar to S. indica var. obtusifolia in having rosette and quadrate nectar scales, as well as similar to S. jiaozishanensis and S. ambigua in reddish purple petals and corymbiform inflorescences. However, the new species with the combined morphological characters of compact rosette is different from S. indica var. obtusifolia lax rosette, S. jiaozishanensis and S. ambigua without rosette. The quadrate nectar scales are also distinguished from S. jiaozishanensis oblong or kidney-shaped nectar scales.

Description. Plants terrestrial or lithophytic, perennial, 2–14 cm tall. Roots fibrous. Leaves with basal rosette, 2 × 1 cm in diam, orbicular- lanceolate, apex acute, 1–3 × 0.9–1 cm. Flowering stems 5–11.5 cm long, glabrous; bracts alternate, lanceolate, red with purple spots, 3.2 × 0.7 cm. Inflorescences corymbiform, ca. 2.5 × 2 cm in diam. Flowers ca. 5.4 × 4.7 mm in diameter. Sepals ovate-lanceolate, ca. 2.2 × 1.1 mm, densely reddish purple papillate, apex obtuse. Petals yellowish, deeply purplish red upward, broad triangular, 4 × 1.9 mm, minutely papillate abaxially, apex usually reflexed. Stamens oblong-cordate, yellowish, ca. 2–3 mm, anthers longitudinally robed, purple, pollen yellow. Nectar scales quadrate, ca. 0.48 × 0.88 mm. Carpels 5, lanceolate 2–3 mm. Styles 0.6–1 mm long. Flower July to October. During the post-blooming phase, bracts and leaves are prone to abscission.

Distribution and habitat. Sinocrassula ganluoensis is currently known only from west and south west Sichuan ( China). Two populations were found in granite crevices, dry stony, or gravelly slopes at elevations from 860 to 1680 m.

Additional specimens examined (paratypes). CHINA. Sichuan: Sijiazhai Village, Kangding City, Ganzi Tibetan Autonomous Prefecture, Sichuan Province, elev. ca. 1683 m, 30.400371 N, 102.120510 E, on the granite crevices, 9 July 2023, Jing Zhao et al. YUS-13920 (YUKU!).

Etymology. The epithet ganluoensis refers to Ganluo County, location where the species was discovered. Its Chinese name is suggested as ‘flffiƃṯ (gan luo shi lian)’.
