The lines connecting elements are called "branches". Nodes without children are called leaf nodes, "end-nodes", or "leaves". Every finite tree structure has a member that has no superior. This member is called the "root" or root node. The root is the starting node. But the converse is not true: infinite tree structures may or may not have a ...
Kohekohe is notable for having characteristics normally associated with trees growing in the tropics, for example, its flowers and fruit grow directly from the trunk or branches (known as cauliflory), and it has large, glossy, pinnate leaves up to 40 cm in length.
It is a handsome, small, erect evergreen tree, with deep green leaves growing in dense clusters. Its flowering season is around February to April. The ashoka flowers come in heavy, lush bunches. They are bright orange-yellow in color, turning red before wilting. As a wild tree, the ashoka is a vulnerable species.
Vachellia xanthophloea (previously Acacia xanthophloea) is a tree in the family Fabaceae, commonly known in English as the fever tree. [3] This species of Vachellia is native to eastern and southern Africa (Botswana, Kenya, Malawi, Mozambique, Somalia, South Africa, Eswatini, Tanzania, Zambia, Zimbabwe).
The root has depth zero, leaves have height zero, and a tree with only a single vertex (hence both a root and leaf) has depth and height zero. Conventionally, an empty tree (a tree with no vertices, if such are allowed) has depth and height −1. A k-ary tree (for nonnegative integers k) is a rooted tree in which each vertex has at most k children.
The following is a list of individual trees. Trees listed here are regarded as important or specific by their historical, national, locational, natural or mythological context. The list includes actual trees located throughout the world, as well as trees from myths and religions .
Araucaria are mainly large trees with a massive erect stem, reaching a height of 5–80 metres (16–262 ft). The horizontal, spreading branches grow in whorls and are covered with leathery or needle-like leaves. In some species, the leaves are narrow, awl-shaped and lanceolate, barely overlapping each other; in others they are broad and flat ...
It is slow-growing, very hardy to drought and fairly frost-resistant. The light-grey colored thorns reflect sunlight, and the bipinnate leaves close when it is hot. [6] The wood is dark reddish-brown in colour and extremely dense and strong. It is good for fires, which leads to widespread clearing of dead trees and the felling of healthy trees.
