Step 1: Understanding the Concept:
Dendrological identification of forest trees relies on macro-morphological bark, leaf, fruit, or exudate features that remain stable and visible year-round.
Step 2: Detailed Explanation:
- Terminalia elliptica (commonly known as Indian Laurel, Asan, or Saj) is a prominent, large deciduous canopy tree of Indian forests.
- The tree is characterized by a dark grey to black, thick, deeply fissured bark.
- This bark cracks into distinct rectangular blocks, closely resembling the scaly skin of a crocodile, which has earned it the common descriptive name "crocodile bark tree."
- Other species in the family like Terminalia arjuna have smooth, flaky white bark, distinguishing them clearly from T. elliptica.
Step 3: Final Answer:
Terminalia elliptica is recognized and identified in the field by its distinct crocodile bark.
