Abstract: Two new species of Orchidaceae from China, Bulbophyllum malipoense and Arachnis zhaoi, are described and illustrated. The former is related to B. unciniferum, from which it differs by having clustered, ovoid-globose pseudobulbs, smaller leaves 2 - 3.5 cm long, and shorter lateral sepals 1.4 - 1.7 cm long and with their middle margins connate to each other; the latter is akin to A. labrosa , from which it differs by its pale yellow-green flowers lacking red-brown marking, and its petals slightly broader than sepals.

Key words: Bulbophyllum malipoense
