DENDROLOGY

Detailed explanation-1: -The Cyathea gigantea is the largest among these four species and is known to grow as high as coconut trees while the Cythea spinulosa stands out because of the spikes on the trunk of the plant that give the fern its name, he added.

Detailed explanation-2: -This fern can grow to 40 feet (12.2 meters) in height, and its elegant, arching fronds can be over 10 feet (3.1 meters) in length.

Detailed explanation-3: -Tree ferns are not actually trees, but with their tall ‘trunks’ and dramatic crown of fronds, they do look very tree-like. The trunk is actually a mat of fibrous aerial roots that need to be kept moist. The most common species tree fern grown in the UK is Dicksonia antarctica.

Detailed explanation-4: -While tree ferns can have single, thick trunk-like stems and can grow to a height of more than 15 metres, they are never woody. They’re also incredibly hardy-tree ferns are often the first plants to show signs of recovery in the early weeks after bushfires.
