The image is a photograph of a signboard in a garden. The signboard is rectangular in shape and has a green background with white text. On the left side of the signboard, there is an illustration of a bunch of acronychia pedunculata, a type of flowering plant. The illustration is in black and white and shows the leaves and flowers of the plant. 

On the right side, there are two illustrations of white flowers, one on the top right corner and the other on the bottom left corner. Below the illustrations, it reads "Rutaceae" in Chinese, which translates to "Habit: Tree" in English. The text below the illustrations reads "Flowering Season: April to August".

The signboard appears to be located in a wooded area, as there are trees and shrubs visible in the background.
