Branch attachment in common ash Fraxinus excelsior L. Figure 1: Anatomical drawing of the wood grain of a branch attachment in a tree. Initially branches are mechanically attached to the trunks of trees by forming interlocking wood grain patterns at the top of the joint, within what is known as 'axillary wood' (Fig. 1).
Rooted phylogenetic tree optimized for blind people. The lowest point of the tree is the root, which symbolizes the universal common ancestor to all living beings. The tree branches out into three main groups: Bacteria (left branch, letters a to i), Archea (middle branch, letters j to p) and Eukaryota (right branch, letters q to z).
The crown is the spreading top of a tree including the branches and leaves, [29] while the uppermost layer in a forest, formed by the crowns of the trees, is known as the canopy. [30] A sapling is a young tree. [31] Many tall palms are herbaceous [32] monocots, which do not undergo secondary growth and never produce wood.

The branches and leaves of a tree. Looking up into the branch structure of a Pinus sylvestris tree. Leafless tree branches during winter. A branch, also called a ramus in botany, is a stem that grows off from another stem, or when structures like veins in leaves are divided into smaller veins. [1]
Pictorial representations of the Jesse Tree show a symbolic tree or vine with spreading branches to represent the genealogy in accordance with Isaiah's prophecy.

Inosculated branches drawn by Arthur Wiechula (19th century) Beech tree trunks conjoined. Inosculation is a natural phenomenon in which trunks, branches or roots of two trees grow together in a manner biologically similar to the artificial process of grafting. The term is derived from the Latin roots in + ōsculārī, "to kiss into/inward ...
Merkle tree. An example of a binary hash tree. Hashes 0-0 and 0-1 are the hash values of data blocks L1 and L2, respectively, and hash 0 is the hash of the concatenation of hashes 0-0 and 0-1. In cryptography and computer science, a hash tree or Merkle tree is a tree in which every "leaf" node is labelled with the cryptographic hash of a data ...
