Definition
Genus Citrullus refers to a group of plants related to the watermelon. 🍉 It's a botanical classification, like sorting species into related groups. Think of it as the 'last name' in the plant world; for example, Citrullus lanatus (watermelon) has 'Citrullus' as the genus. These plants are mostly vines found in Africa and Asia. Some species are cultivated for their fruit, while others remain wild. Knowing the genus helps scientists understand plant relationships and evolution, just like knowing family history.
