Coconut palm leaves. Cocos nucifera is a large palm, growing up to 30 metres (100 feet) tall, with pinnate leaves 4–6 m (13–20 ft) long, and pinnae 60–90 centimetres (2–3 ft) long; old leaves break away cleanly, leaving the trunk smooth. [6]
The leaf base of some palms is also used to extract coir. [citation needed] The oldest leaf forms the outermost layer of the crownshaft. Eventually the lowest palm frond dies back, the outer layer of the crownshaft splits, the leaf unwraps and pulls away from the trunk exposing the new crownshaft surface.

Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
The coconut husk and shells can be used for fuel and are a source of charcoal. [17] In Thailand, the coconut husk is used as a potting medium to produce healthy forest tree saplings. A dried half coconut shell with husk can be used to buff floors. It is known as a bunot in the Philippines and simply a "coconut brush" in Jamaica.

The coconut palm has made Sri Lanka a particularly beautiful place. The graceful trunk of the tree rises to a height up to 30 m (98 ft) ending in a compact crown of 30-40 large feather like leaves. Each leaf is about3–4 m (9.8–13.1 ft) in length.
