            <p> Liparis macrosepala Z.W. Wang, Y. Zhang &amp; W.C. Huang sp. nov.</p>
            <p> Figs 2, 3 Chinese name:  大萼羊耳蒜</p>
            <p>Type.</p>
            <p>  China. Yunnan Province (云南),  Xishuangbanna (西双版纳), Mengla County (勐腊县) epiphyte on the tree trunk, 1620 m elev., 23Nov 2021, Zhengwei Wang, Xiaochen Li, Yu Zhang &amp; Zhijin Wu, WZW04247 (holotype: CSH!) </p>
            <p>Diagnosis.</p>
            <p> 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. </p>
            <p> Epiphytic herbs. Roots slender, flexuose. Pseudobulbs clustered, ovoid-fusiform, slightly compressed laterally, 1-2  × 0.5-1 cm, upper half with 4-5 widely spaced leaves. Leaf blade ovate-oblong, 1.8-2.3  × 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  × 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  × 3-3.6 mm, 1-veined, abaxially carinate, apex acute; lateral sepal oblong-ovate or ovate-lanceolate, 5-6  × ca. 0.6 mm long, abaxially slightly carinate. Petals narrowly linear, 3-4  × ca. 0.2 mm; lip elliptic, 2-3  × 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. </p>
            <p>Phenology: Flowering in November-December.</p>
            <p>Distribution and habitat.</p>
            <p> It is found on tree trunks on a limestone ridge-top evergreen broad-leaved forest at an elevation of 1500-1700 m in Mengna County, Xishuangbanna Autonomous Prefecture, Yunnan Province,  People’s Republic of China. The habitat presents a tropical monsoon climate. </p>
            <p>Etymology.</p>
            <p>The species epithet refers to the large and conspicuous dorsal sepal of the flower.</p>
            <p>Taxonomic notes.</p>
            <p> Liparis macrosepala differs from  L. delicatula in its 4 to 5 leaves with slightly crispate margins on their apical half and single pair of wings on the column. Its entire, not Y-shaped petals and sessile lip (i.e. without a claw) easily distingush  L. macrosepala from  L. fissipetala . The dosal sepal of  L. assamica is narrowly ovate-oblong, in contrast with the heart-shaped dorsal sepal of  Liparis macrosepala .  Liparis resupinata is distinguished from  L. macrosepala by its 10-50-flowered raceme and the column with a single pair of broad wings, each with a retrorse thread. The main differences between these closely-related species, according to our phylogenetic analyses, are summarised in Table 2. </p>
            <p>Conservation assessment.</p>
            <p>The new species was found in a ridge-top evergreen broad-leaved forest on a limestone mountain. Despite numerous surveys in the areas, only six mature individuals were found without fruits or evidence of cross-pollination.</p>
            <p>This extremely small effective population occurs in a touristic zone which is a serious threat to the survival of the species. Consequently, the species can be assessed as Critically Endangered (CR, D), based on current information and following IUCN guidelines (IUCN 2019).</p>
