👉 In botany, a "zygomorphous" refers to a type of plant that exhibits a characteristic shape or structure that is similar to that of another plant. This can occur as a result of genetic variation, adaptation to different environmental conditions, or through a combination of these factors. For example, the zygomatic arch (the part of the head between the eyebrows and nose) in many species of plants, such as poplars, is similar to that of the human jawbone.
