ID for miniature

[kavanaru]

A vendor from Bangkok, who is coming to visit one of the orchids nurseries I use to visit in Switzerland, send me some pictures of miniature plants he will bring with him. All of them but 3 were identified with latin names. I could identify 2 of the NOIDs (Dendrobium peguanum and Trichoglottis triflora), however, I could not identify this plant. I asked the vendor, but I only received what I suppose to be the chinese name (Chiang Xi Ging). Does anybody here knows this species?

P.S.- Pictures are posted with permission of the vendor.
