Chiloschista quangdangii Vuong & Aver. sp. nov. (Fig. 1) Type:— VIETNAM. Ha Giang Province, Quan Ba District, Quyet Tien Commune, forest around the Lung Muoi Village, 6 June 2023, Truong Ba Vuong, Ngo Quang Dang, BV 1748 (holotype VNM00063979). Paratype:— VIETNAM. Ha Giang Province, Quan Ba District, Quyet Tien Commune, forest around the Lung Muoi Village, 6 June 2023, Truong Ba Vuong, Ngo Quang Dang, BV 1749 (VNM00063980). Diagnosis:—The newly discovered species can be distinguished from the closely related C. parishii by its narrowly saccate spur-like hypochile and the presence of a small callus on the lip disc. Additionally, it differs from the similar C. glabrisepala due to its densely hairy hypochile on the inside and the small callus on the disc. Etymology:—The species is named after Mr. Ngo Quang Dang, who successfully cultivated the plant and kindly provided the materials for this study. Description:— Herb leafless (during anthesis), miniature, monopodial, with an abbreviated stem ca. 3 mm long and many long, glabrous, flattened, green roots. Inflorescence green, marked with brown, up to 13 cm long, covered by short white hairs; peduncle ca. 5 cm long, with 3 distant brownish sterile bracts; rachis ca. 8 cm long, bears 2–15 flowers; floral bracts rectangular-ovate, acuminate, ca. 3.5–4 mm long, keeled and, sparsely hairy with short hairs abaxially. Pedicel and ovary ca. 3 mm long, densely white hairy. Flowers open from the base, sepals and petals yellow with many large orange blotches, lip almost white, side lobes with 2–3 orange dots outside and many orange warty streaks inside. Median sepal obovate, 6.5–7 mm long, 4–5 mm wide, rounded at the apex, slightly retuse and sparcely ciliate along the margin. Lateral sepals broadly obovate, slightly oblique, 5.5–6 mm long, ca. 3–4 mm wide, rounded or blunt at the apex and sparcely ciliate at margin. Petals obscurely rectangular, 5.5–6 mm long, ca. 4 mm wide, truncate or rounded at apex, glabrous on both surfaces and ciliate along the margin. Lip 3-lobed, ...
