Guihaia

Guihaia is a genus of three species of dioecious^[1] palms found in China and Vietnam.^[2][3][1][4] Perhaps its most distinctive characteristic is that it is the only palm with palmate leaves that has reduplicate (A-shaped) leaf folds. All other palmate leaves have induplicate (V-shaped) leaf folds. Guihaia lancifolia has undivided leaves.^[5]
