81BDBCAD156054AE829A15F82007C187.taxon	diagnosis	Diagnosis. Liparis macrosepala is characterised by the ovoid-fusiform, slightly compressed pseudobulbs with 4 or 5 alternate leaves on their apical half, these with slightly crispate margins, dorsal sepal ovate with cordate base, broadly elliptic, ca. 4 mm long, 2 callus-shaped and thickened folds, base with 2 oblong lobes on both sides, centrally with 1 thickened, concave callus, column with a single pair of arcuate wings. Epiphytic herbs. Roots slender, flexuose. Pseudobulbs clustered, ovoid-fusiform, slightly compressed laterally, 1 - 2 x 0.5 - 1 cm, upper half with 4 - 5 widely spaced leaves. Leaf blade ovate-oblong, 1.8 - 2.3 x 0.8 - 1.2 cm, apex acuminate, base contracted into a short petiole, articulate, margins of their apical half slightly crispate. Peduncle 7 - 10 cm long, with several sterile bracts 2 - 5 mm long; raceme with 7 - 10 flowers arranged in zigzag manner. Floral bracts broadly ovate with cordate base, 2 - 3 x 1 - 1.5 mm, acute. Flowers greenish-orange; pedicel and ovary ca. 7 mm long. Dorsal sepal broadly ovate with cordate base, 3.2 - 5 x 3 - 3.6 mm, 1 - veined, abaxially carinate, apex acute; lateral sepal oblong-ovate or ovate-lanceolate, 5 - 6 x ca. 0.6 mm long, abaxially slightly carinate. Petals narrowly linear, 3 - 4 x ca. 0.2 mm; lip elliptic, 2 - 3 x ca. 1 mm, apex apiculate, base bearing a bituberculate callus, then expanded on each side into a thickened, folded, rounded lobe, with 1 excavation with raised margins between the lobes. Column straight, ca. 2 mm long, with a pair of subtriangular, obtuse wings on each side near the middle and a ridge on the back of the column. Anther cap hemispherical, pale yellow; pollinia 4 in 2 pairs with one pollinium of each pair smaller than the other, waxy, brownish, with minute apical viscidium. Phenology: Flowering in November-December.	en	Wang, Zhengwei, Zhang, Yi, Zhang, Ze, Li, Xiaochen, Wu, Zhijin, Yan, Lan, Lu, Aixian, Xie, Chengzhi, Hu, Chao, Huang, Weichang (2022): Liparis macrosepala (Orchidaceae), a new species from southwest China with its phylogenetic position.
