Liparis tianchiensis (Orchidaceae, Epidendroideae), a new species from Wenxian County, Gansu Province, China, is described and illustrated, based on morphological characters. Liparis tianchiensis is morphologically similar to L. damingshanensis, L. pauliana and L. mengziensis with erect, lax flowered-inflorescences, small persistent floral bracts, small greenish-purple flowers, spreading sepals, free reflexed and linear petals, a lip with 2 calli near the base and an arcuate column. Liparis tianchiensis differs from L. pauliana by the single and much smaller leaf, shorter sepals and petals, smaller and reflexed oblong lip. It differs from L. mengziensis by having fewer and larger flowers and not connate lip apex. The novelty mostly resembles L. damingshanensis, but can be readily identified by having longer sepals and a reflexed oblong lip. Liparis tianchiensis only occurs in evergreen broad-leaved forest around a mountain lake in Wenxian County, Gansu Province, China.

Bulbophyllum reflexipetalum, a new species from Motuo County, Southeast Xizang, China, is described and illustrated here. This new species belongs to Bulbophyllum sect. Umbellata Bentham & J. D. Hooker, and it is morphologically similar to B. umbellatum Lindley, B. guttulatum (J. D. Hooker) N. P. Balakrishnan and B. salweenensis X.H. Jin, but is distinguished from them by having reflexed petals, base of dorsal sepal with 1 dentate on each side, lip with significantly revolute margin, adaxially with dark brown spots or patches and one longitudinal groove.

Liparisnapoensis, a new orchid species belonging to section Cestichis from Guangxi, China is described and illustrated. It occurs in the karst limestone forest. The new species is morphologically similar to L.viridiflora and L.somae, but can be readily distinguished by having narrowly oblong-falcate petals; flabellate-quadrate lip distinctly concave at base and emarginate at apex; conspicuously arcuate column with a pair of wedge-shaped wings.

Bulbophyllumchrysolabium, a new species belonging to section Racemosae from Yunnan, China is described and illustrated. The species is related to B.orientale and B.morphologorum, but differs by having the following set of characters: obliquely broadly-based triangular petals with a long filiform apex; lip densely glandular papillose and conspicuously ciliolate along margins; lip auricles well developed, narrowly falcate, tapering to a long sharp point at the apex; stelidia subulate and twisted inwards, slightly exceeding operculum. The conservation status of B.chrysolabium is assessed and taxonomic notes are provided.
