摘　　要：对兰科(Orchidaceae)石豆兰属(Bulbophyllum)二新种,副萼石豆兰(B.malipoense Z.J.Liu,L.J.Chen&W.H.Rao)和小副萼石豆兰(B.minor Z.J.Liu,L.J.Chen&W.H.Rao)作了描述和绘图。该二新种属于石豆兰属副萼组(Bulbophyllumsection BisetaJ.J.Verm.ex N.Pearce,P.J.Cribb&J.Renz),与该组的刺萼石豆兰(B.bisetum Lindl.)相似,区别在于两新种的叶片先端二裂和唇瓣无毛。小副萼石豆兰与副萼石豆兰的区别在于假鳞茎椭圆球形;叶片卵状椭圆形,长1.2～2 cm;侧副萼片较短,长约1 mm;中副萼片几乎与两侧萼片边缘合生。Bulbophyllum malipoense Z.J.Liu,L.J.Chen W.H.Rao and Bulbophyllum minor Z.J.Liu,L.J.Chen W.H.Rao,two new orchid species from China,are described and illustrated.Both of them belong to Bulbophyllum section Biseta,and are akin to B.bisetum.Bulbophyllum malipoense differs from B.bisetum by having bilobed-tipped leaves and a glabrous lip,and B.minor differs from B.malipoense by having ellipsoid-globose pseudobulbs,ovate-elliptic leaves 1.2-2 cm long,shorter lateral calycules ca.1 mm long,and a central calycule almost entirely adnate to the connate margins of the lateral sepals.
