Cymbidium quinquelobum,a new orchid from Yunnan, is described and illustrated.It is akin to Cymbidium wenshanense Y.S.Wu et F.Y.Liu,from which it differs by having a 5-lobed lip that is fused at base to the basal margins of the column forming a tube 8-10mm long.
Phalaenopsis malipoensis Z.J.Liu et S.C.Chen,a new species of Orchidaceae from southeastern Yunnan,is described and illustrated.This is a quite distinct species from those known from China and its adjacent regions.It shows a faint resemblance to Phalaenopsis gibbosa Sweet of Laos and Vietnam,but differs by having narrower petals,not zigzag rachis and a large callus on the mid-lobe of the lip which is deeply forked with each arm dividing into 2 filiform-linear antennae.
