What is the difference between a palm tree and a sunflower tree?

The scientific name of the palm tree is Palm, and the scientific name of the sunflower tree is Palmetto. You can actually find a lot of related content on Baidu about the difference between these two trees. I will not copy those, but just talk about my own judgment method:

Mainly look at the leaves. Palm leaves are much larger than palm leaves, and the cracks on the leaves are much shallower, so palm leaves are more suitable for making fans. Another most obvious difference is that the tips of palm leaf lobes are mostly stiff, while the tips of palm leaf lobes are V-shaped long (up to 50 cm long) filamentous drooping lobes.
