Four new species, Cheirostylis calcarata X. H. Jin & S. C. Chen, C. malipoensis X. H. Jin & S. C. Chen, Gastrochilus alatus X. H. Jin & S. C. Chen, and G. malipoensis X. H. Jin & S. C. Chen, together with seven new records, Bulbophyllum rolfei, B. ovatilabellum, Eria cristata, G. affinis, Listera micrantha, Luisia macrotis, and Oberonia teres, of Orchidaceae are reported from Yunnan, China. Cheirostylis calcarata differs from its ally C. spathulata by having a vertical rhizome, a spurred lip, and stylidia much longer than rostellum arms;Cheirostylis malipoensis from C. yunnanensis by its internodes with constricted ends, hypochile with a longitudinal septum, and stylidia shorter than rostellum arms;Gastrochilus alatus from G. distichus by having yellow flowers, and wider and membranous epichile with longitudinal ridge centrally;Gastrochilus malipoensis from G. calceolaris by its racemose inflorescences, and glabrous and semicircular epichile. The new record, Bulbophyllum rolfei, is characterized by its dorsal sepal half as long as the lateral sepals, inflorescence equaling or exceeding leaves, lateral sepals connate for at least part of their length;Bulbophyllum ovatilabellum by its forked lateral veins in dorsal sepal and a U-shaped callus on the lip;Eria cristata by its purple and reflexed bracts, white to cream lip with three calli adaxially;Gastrochilus affinis by its dentate-margined epichile with two ridges ranging from base to apex;Listera micrantha by its trilobed-tipped lip;Luisia macrotis by lateral sepals as long as lip, petals less than 5 mm wide, and lip dark purple with cordate epichile;Oberonia teres by its terete leaves and emarginated midlobe.
