👉 Exochilum is a type of plant that grows in cold climates, often found on rocky or sandy soil. It typically has a thin, waxy outer layer called exoskeleton and can be divided into two main types: exocarp (the inside part) and exosperm (the outside). Exochilums are adapted to survive in extreme environments by storing water and nutrients, which helps them thrive in arid or semi-arid regions.
