well, plant's official names must be in latin. "Viking" is english. The name "viking" was given by the man who started taking cuttings of this plant from the wild to sell them - through other thai growers - at Chatuchak, the most famous thai market. The plants has been since then known around with this name, but it's not the official one. That's why we all call it "viking" using those two little symbols on the sides of the name. Because it's actually a nickname.
