3. Moreover, there will be a bract at the bottom of the pedicel of each flower where it is connected with the flower axis, closely surrounding the ovary of the flower. Usually, the bracts of ground orchids are longer, which can reach about half the length of ovary. The bracts of epiphytic orchids are very short, usually one-third of the ovary

4. After the orchid is fertilized, the ovary will gradually expand and develop into fruit, and the skin color of the fruit will change from yellow green to brown. When its fruit matures, it will split longitudinally and expose its seeds
