This is the contorted form of the Japanese Bitter Orange, Poncirus trifoliata. Sometimes called 'monstrosa', or the Japanese name Karatachi 'hiryo'. Often used as a dwarfing rootstock for citrus varieties, it is hardy to around -15C and produces round fruit about 2-4cms diameter. The fruits look like small oranges but are extremely bitter and often full of seeds.
The photos here were taken in my garden in England on a beautiful sunny morning in early November. The plants are all six year old seedlings, at various stages of leaf fall. They have not yet fruited.
