Bhutan, NE India, SW China (Yunnan).</p> <p>Conservation status:—Preliminarily estimated as nationally critically endangered, CR (B1a,b(i-iii,v), B2a,b(iiii,v); D). Available observations indicate that the species in Vietnam meets the following IUCN Red List Categories and Criteria (IUCN 2019) as following: only two populations were discovered with extent of occurrence (EOO) less than 100 km 2 (B1a) and the area of occupancy (AOO) less than 10 km 2 in two known locations (B2a); observed in both cases the expected continuing of decline (b) of extent of occurrence (i), area of occupancy (ii), area, extent and quality of habitat (iii), number of mature individuals (v); populations are very small with estimated number of mature individuals less than 50 (D).</p> <p>Notes:—All early reports of this species in Vietnam were doubtful (Seidenfaden 1992, Averyanov 1994, Averyanov &amp; Averyanova 2003a) and later were identified as a new species, Cleisostoma melanorachis Averyanov &amp; Averyanova (2006a, b). The present report represents actually the first verified record of this species in Vietnam based on observations in nature and collected voucher herbarium specimens. Respectively, we provide here the description and illustrations for this rare species assessed in Vietnam as Critically Endangered.</p> <p>In floral morphology, Cleisostoma aspersum resembles described earlier C. flavescens Averyanov &amp; Averyanova (2003b), but well differs in shorter stems less than 3 cm (vs. stem longer than 3 cm), leaves 8–13 cm long, truncate, 4–5 denticulate at apex (leaves 12–20 cm long, bilobulate at apex with roundish lobes), simple inflorescence (vs. inflorescence paniculate, many branching), lip side-lobes shallowly bilobulate, flat (vs. lip side-lobes entire, flabellate, finely crisped along the margins). Cleoisostoma aspersum also resembles C. discolor Lindley (1845: 59), but well differs in twice smaller flowers, fleshy lip (vs. lip thin textured), entire or slightly crenulate lip margin (vs. lip margin erose to irregular denticulate), side-lobes erect, rectangular, shallowly bilobed (vs. side-lobes recurved, entire, broadly flabellate), and median lobe fleshy, broadly triangular, upright ascending (vs. median lobe thin, oblong triangular, recurved).</p> <p>Studied specimens:— VIETNAM, herbarium specimen prepared from cultivated plant in 20.06.2022, by L.

Primary evergreen broad-leaved and mixed forests on granite at elevation 1000–2000 m a.s.l. Flowers in September.</p> <p>Distribution:— VIETNAM. S Vietnam, Kon Tum Province, Ngoc Linh Mountains. Endemic.</p> <p>Conservation status:—Despite many-years, special field searches of professional botanists and numerous orchid enthusiasts only few samples of this extremely rare species were found in one location. Being into consideration vast deforestation in Ngoc Linh Mountains it may be expected that this species stands on the verge of full extinction in the nature. According to available data, having one population with EOO and AOO less than 100 km 2 and 10 km 2 respectively, expected coming extinction, and very small population with less than 50 mature individuals, it may be preliminarily assessed as globally Critically Endangered – CR (B1a,b(ii,iii), B2a,b(ii,iii); C1a(i,ii), C2a(i,ii); D).</p> <p>Notes:—According to plant and floral morphology, the new species has rather isolated, intermediate taxonomic position between C. sect. Cleisostoma (Seidenfaden 1975: 10) and C. sect. Paniculata Seidenfaden (1975: 34). The structure of its pollinarium has triangular conduplicate stipe with large rectangular longitudinally concave viscidium, very large discoid stigma broader than the column itself, dense bunches of white hairs at the column apex, and dense inflorescence are features unique in the genus (Averyanov et al. 2015). We see no any close relatives for our plant among its congeners.</p> </div>	https://treatment.plazi.org/id/03FA834FDD4A113F5C8CFA8AFE8C9D97	Public Domain	No known copyright restrictions apply.

Bhutan, India (Assam, Meghalaya, Nagaland, Arunachal Pradesh, Sikkim, West Bengal).</p> <p>Conservation status:—Vietnamese population of this rare species is distant from its nearest location in NE India for about 2500 km, which considerably expands EOO. Meanwhile, the species was not ever reported on vast areas between newly discovered location in Vietnam and main species area in Bhutan and NE India. In this connection, it may represents isolated disjunctive refuge do not connected directly with main species area. According to available data, lone population in Vietnam has AOO surely less than 10 km 2 with the number of mature individuals less than 50. Being into consideration the extensive deforestation in the region of species location its conservation status should be preliminarily estimated as nationally Critically Endangered, CR (B1a,b(i-v); C2a(i); D).</p> <p>Notes:—In comparison with plants from Bhutan and NE India, studied Vietnamese specimens have somewhat larger leaves, longer inflorescences, and distinctly larger flowers.

Sepals narrowly ovate, concave, blunt to obtuse, (4.5)5–6(6.5) mm long, (2.2)2.5–3(3.2) mm wide; median sepal distinctly cucullate; lateral sepals somewhat oblique. Petals narrowly lanceolate, obtuse to acute, (4.2)4.5–5(5.5) mm long, (0.6)0.7–0.8(0.9) mm wide. Lip spurred, (6)6.5–7.5(8) mm long (from spur apex to the apex of epichile), 3-lobed; side-lobes fleshy, rectangular, truncate, erect, (1)1.1(1.2) mm long, (0.7)0.8(0.9) mm tall, distal corner hook-like incurved; median lobe fleshy, obscurely 3-lobulate, (2.2)2.5–3.5(3.8) mm long and wide, entire of finely erose along the margin; lateral lobules half-round, medial twice larger than side-lobules; spur conoid, at an acute angle to the ovary, (1.8)2–2.2(2.5) mm long, (1)1.2–1.8(2) mm in diameter at base, round or obscurely truncate at apex. Spur back-wall inside with large glabrous or finely papillose callus, at front rectangular, (0.5) 0.6–0.7 mm wide, (1.1)1.2–1.3(1.4) mm long, with longitudinal groove, from sideview half-circular, 0.6–0.7 mm tall. Spur front-wall inside with two roundish lateral, glabrous or finely papillose calli placed at spur entrance, between which is placed median keel coming from the base of medial lobe to the spur and forming incomplete septum. Column half-cylindric, (3.2)3.4–3.8(4) mm tall, (1.4)1.5–1.6(1.7) mm wide, near apex at front with prominent beak-like rostellum (0.9)1–1.1(1.2) mm long; stigma at front of column, in form of large ovate concave hollow.

Stipe (tegula) scarious, filiform, (1.4)1.5(1.6) mm long, suddenly widening in proximal part, distally with very small roundish viscidium, about 0.2 mm in diameter. Fruits not seen.</p> <p>Ecology and phenology:—Epiphyte. Primary evergreen broad-leaved forests on silicate parental rocks at elevation 1000–2000 m a.s.l. Flowers in July–August.</p> <p>Distribution:— VIETNAM. Provinces: Son La (Pha Din Pass area), Dien Bien, and Kon Tum (Ngoc Linh Mountains).</p> <p>Conservation status:—The species is known presently only from two locations on the border of Dien Bien and Son La provinces and in the center of Kon Tum Province. These locations placed on northern and southern Vietnam are distant from each other on about 850 km. Hence, formally its EOO may be at least 850 km 2. Nevertheless, according to available data its AOO is may be less than 10 km 2. Known populations are severely fragmented, include very few mature individuals and decline due to deforestation and habitat destruction. Due to these conditions the conservation species status may be estimated as Critically Endangered –CR (B2a,b(i-v); C1a(i,ii), C2a(i,ii); D).</p> <p>Notes:—New species morphologically is most close to known from N Thailand and Yunnan, S. yunnanensis Z.H.Tsi (Tsi 1984: 476) and described from northern Vietnam sympatric species, S. brevilabia Averyanov (2012: 133). However, it differs well from these species in plant habit and floral morphology. Their morphological features are summarized on the Table.</p> </div>	https://treatment.plazi.org/id/03FA834FDD4511345C8CFE52FE539A92	Public Domain	No known copyright restrictions apply.

Stems rigid, ascending, simple or few branching at the base, (4)5–7(8) cm long, covered by leaf sheaths throughout, leafy in apical half, with few thick white roots near base. Leaves sessile with distinct articulation at the base; leaf blade rigid, lorate, distinctly conduplicate, keeled below, arching, with shortly bifid apex, (6)10–16(18) cm long, (0.5)0.6–1.1(1.2) cm wide. Inflorescences axillary, many branched, erect or spreading horizontally, lax panicle, (4)6–24(26) cm long; peduncle 0.5–1(1.5) cm long, sheathed at base; branches (2)3–9(11) cm long, branching, rachis slightly zig-zag, (0.5)1–6(8) cm long; floral bracts brownish, broadly ovate, blunt to obtuse, 0.5–0.7 mm long. Flowers (5)5.5–6(6.5) mm across; sepals and petals white brown orange with pale yellow at base and apex; lip white with purple tint at center, later pale yellowish; column brown orange; anther cap and pollinaria light yellowish. Pedicel and ovary olive greenish, (3.5)4–5(5.5) mm long, 0.8–1 mm in diameter. Sepals and petals narrowly obovate to oblong narrowly obovate, blunt to obtuse, spreading, (2.5)2.7–3(3.2) mm long, (0.7)0.8–1(1.1) mm wide, petals narrower and slightly oblique. Lip spurred, 3-lobe, fleshy, (3.6)3.8–4(4.2) mm long from lip to apex of spur; side-lobes rectangular, erect, slightly pointed at front, densely hairy with stiff white hairs; median lobe broadly triangular, 3-lobulate, lateral lobules small, ovate triangular, median lobule twice larger, broadly ovate, round at apex; spur narrowly conoid, 1.5–1.7 mm long. Column foot-less, glabrous, short and stout, 0.6–0.7 mm tall and wide, with round concave stigma at front. Anther cap hemispheric, 0.6–0.7 mm in diameter, shortly beaked. Pollinarium stipe slender with small round viscidium, pollinia 2, globular, incompletely divided into 2 unequal hemispherical bodies. Fruits fusiform, shortly stalked, about 2 cm long.</p> <p>Ecology and phenology:—Epiphyte in lowland evergreen broad-leaved forests. Flowers in May–June.</p> <p>Distribution:— VIETNAM (Kon Tum Province), NE India, Bangladesh, Myanmar, Thailand.</p> <p>Conservation status:—The discovered location of the species in Vietnam near the border of Laos is not much surprising and actually is allied to main species territory spreading from NE India to Thailand. Meanwhile, it expands the species distribution area on more than 200 km in the E direction. The lone discovered population has AOO surely less than 10 km 2 with the number of mature individuals less than 50, decreasing due to deforestation of habitat. According to available data the conservation species status in both countries may be estimated as nationally Critically Endangered, CR (B2a,b(i-v); C2a(i); D).</p> <p>Notes:—The species was discovered in Vietnam very close to the border of Laos and may be surely found in this country in Attapu Province. Studied specimens differ from “western” plants in glabrous column (vs. column at front shortly hairy), obtuse lip median lobe (vs. lip apex emarginate), slightly larger flowers and little different flower color scheme (figs. 6E-J). They may represent a separate variety or even new, not yet described species, study of which needs more collections.</p> <p>Studied specimens:— VIETNAM, herbarium specimen prepared in 01 June 2022, L.
