1. Aerial Plants: Epiphytes often grow on trees, rocks, or other surfaces but do not derive nutrition from them. They have adapted to absorb moisture and nutrients directly from the air, rainfall, and surrounding debris.
2. Leaves: Epiphytic plants display an array of leaf structures:
- Leaves can be succulent in some epiphytes, helping them store water in dry environments.
- Others have thick and leathery leaves that can withstand harsh conditions.
- The leaves may be simple, entire, or lobed, depending on the species.
3. Roots: Epiphytes possess specialized roots, often called aerial or clinging roots. These roots help attach the plant to various surfaces, including tree bark, rocks, or other host structures, for support rather than nutrient uptake.
4. Stems: The stems of epiphytes can vary greatly:
- Some have elongated, vine-like stems that can hang or climb on trees.
- Others may have erect or creeping stems that spread along surfaces.
- Stems might be flexible or rigid, depending on the plant's adaptation.
5. Flowers: Epiphytes have a diverse range of flowers that can vary in size, color, and shape:
- Many species produce beautiful flowers that bloom periodically.
- Flowers can be tiny and inconspicuous, while others are large and eye-catching.
- The color and shape of the flowers can vary significantly across different epiphytic species.
6. Size: Epiphytes come in various sizes. They can be large and sprawling, such as some epiphytic cacti or certain orchids. Others might be small and delicate, such as某些兰科植物.
It's important to note that there's a great diversity among epiphytes. Different species have evolved distinct characteristics to adapt to their unique environments, leading to a wide range of appearances across the epiphytic group.
