Bracteate flower of a handkerchief tree (Davidia involucrata). Bracts are modified leaves often forming a flower like structure. The white flowers are not petals but two modified leaf bracts. Inside, the flower stamen form a purplish sphere with a pistil at its centre. This Chinese tree has become a popular ornamental tree in Europe and the USA. | |
