Guihaia Explained

Guihaia is a genus of three species of dioecious palms found in China and Vietnam.^{[1] [2] [3] [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.
