Probably pointing out the obvious here, but it's an angraecoid (Angraecum sp. or close relative, e.g., Aerangis sp. maybe). Actually, given the small size I would guess Aerangis of some sort.
One of my favourite groups of orchids. The Darwin orchid (Angraecum sesquipidale) has just the coolest stories behind it. And the flowers are spectacular, as are the scents they give off.
