My vote goes to Brachystelma cathcartensis. It smelled so nasty that I never resampled it, which is why I can't give a very clear accounting of its fragrance. From memory, it was a carrion smell, but a particularly dirty one. Fortunately the plant hugs the ground, and the smell doesn't seem to carry far (I never noticed it at all until I actually stuck my nose in it).
