Four Flowers

There are four flowers in this picture, which are half purple and half white, hanging on the branch. The sepals are total indigo. The petals of these four flowers are thick, the shape of them is like the skirt’s hemline of ladies’, also is like a horn. The color of them is changing from the indigo at the bottom to the white of the edge. The white of the flowers is not pure, it has some purple spots gleams on it. The stamens of the flowers are yellow, the anther on the top is like a grain of wheat. Based on the consensus, the flower might be the size of a fist of a young girl supposedly. The pistils of these flowers are not inconspicuous because of the clusters of the stamens.
