    Abstract

    Two new orchid species, Pinalia fuscinervia J.D. Ya, Z.D. Han & H. Jiang and P. brevistyla J.D. Ya, Z.D. Han & H. Jiang, are described and illustrated from Yunnan, China. In addition, Pinalia leucantha Kuntze is newly recorded for China. Pinalia fuscinervia is morphologically distinct from P. japonica in its brown-veined leaf sheaths, falcate-lanceolate lateral sepals, an ovate and fleshy lip mid-lobe, and a lip disk bearing three yellow lamellae, with the median lamella inconspicuous. Pinalia brevistyla differs from P. leucantha in its lateral shorter sepals and petals; an orange-brown to dark purplish-red lip mid-lobe with irregular verrucate protuberances adaxially, a disk bearing a pair of tooth-like calli, and an extremely short, inconspicuous column foot.
