Bulbophyllum sp (Unknown I.D)

Bulbophyllum sp

I'll like to share photo of this beautiful unknown bulbophyllum from a local nursery recently. According to the owner, the orchid is from some place near PNG.

It appears similarly to Bulbophyllum lepidum, but I am not entirely sure about the I.D. Perhaps someone can help to identify it please? Thanks in advanced.

This commonly grown orchid, Bulbophyllum putidum or common known as 'The Putrid Mastigon' emits a foul smell of rotting matter to attract its pollinator, usually flies. Although, the smell may not be pleasant, its unique lip that moves with the slightest air movement and as well as its crimson red lip color, never fails to 'fascinate' many growers from all over the world.
