 Notes: —Another species, Zeuxine clandestina Blume (1858: 70), is extremely similar to Z. sakagutii, but without field observations and sufficient fresh materials, we hesitate merging Z. sakagutii under Z. clandestina. Meanwhile, Z. parvifolia (Ridley 1903: 87) Seidenfaden (1978b: 82), Z. gracilis (Breda 1829: t. 9) Blume (1858: 69) and Z. affinis (Lindley 1840b: 487) Bentham ex Hooker (1890: 108–109) are also similar to each other and often misidentified. This whole complex needs to be studied further.
