discussion
Taxonomic discussion: — To our knowledge, there had been no subsequent collections of this species since 1997. During recently field work in Yunnan and Guangxi province, we had firstly found and get the fresh materials. Morphologically, it is similar to G. guangtungensis Z. H. Tsi (1996: 139) and G. acinacifolius Z. H. Tsi (1989: 25) by having repent stem and falcate leaves. However, it differs from latters by having the leathery leaves with densely purple-violet spotted or almost entirely purple-violet, inflorescence usually with 3 – 8 - flowered, small flowers (sepals size: 2.5 – 3.0 × 1.5 – 1.8 mm), and epichile triangular, adaxially glabrous (Tsi 1996, Averyanov 1997, Chen et al. 2009).
