Hello, recent storms have resulted in a tree in my garden breaking in two at the trunk. I think it may be a palm tree, but this is just a guess. (image attached of the flowering top of the plant and remaining tree)

Does anyone know what the specific species this tree is? and also, as it has broken in two, is there anything I can do to save it (e.g. saw the trunk at a specific point and treat it) or is it a gonna requiring extraction?

Thanks.
