The researchers studied the early development of the endangered plant Euryodendron excelsum's flower. They used a scanning electron microscope to observe the process. The flower of E. excelsum has both male and female parts and grows in a unique way. The sepals and petals grow in a specific order and arrangement. The stamen, which are the male parts, grow in a ring shape and then divide into groups. The ovary, which contains the female parts, has three sections and a special stigma. Overall, the way E. excelsum's flower develops is different from other plants in the same family.
