dendrochilum identification

[Jade]

two years ago I bought this little cutie as a dendrochilum formosanum. The vendor told me that it was a formosanum with green-cream flowers.
It flowers easily,every year in this period, but I'm not sure it's a formosanum.
Actually, I saw that formosanum has two brown lines on the lip, while mine not.

Can you help me with the identification of my dendrochilum?

(If it could help: It has a very strong scent. Sometimes it almost stinks)
