Pamor Kembang Pete (Stinky Bean)

[Bjorn]

I stumbled upon a pamor called kembang pete. I believe the pete here refers to pete beans, known in English under various names (sator bean, stinky bean, bitter bean, etc.). Personally I find them delicious and that is probably why this pamor immediately intrigued me.

If you compare the below photo of the beans still in their pod, I think it looks very similar to the pattern depicted on the keris' blade. However, kembang means flower, which suggests the pattern should resemble the flowers instead of the beans (flowers also pictured below). Is it possible that kembang here actually does refer to the beans, and not the flowers? Or is that wishful thinking on my part?

Also, I'd love to know what this pamor represents. What are the societal implications? Was it popular, rare, used by a specific sort of people? I'd like to know as much as possible about this pamor, so if anyone has knowledge to share it would be greatly appreciated.
