I recently ordered some chamaerops humilis (European/Mediterranean fan palm) seeds from the seller "jaysseeds" on Amazon (probably not the best place to order seeds but...) and ordered some trachycarpus fortunei seeds (windmill palm) from the same seller. After taking the seeds out of each pack, I notice the seeds look quite similar. They all looked like chamaerops humilis seeds. If I remember correctly, trachycarpus fortunei seeds almost look kidney-bean-shaped.
