 Tree - Wikipedia, the free encyclopedia
Trees are important components of the natural landscape and significant elements in landscaping and agriculture, supplying orchard crops (such as apples).
The earliest trees were tree ferns and horsetails, which grew in vast forests in the Carboniferous Period; tree ferns still survive, but the only surviving horsetails are not of tree form.
This is cited as dbh (diameter at breast height) in tree literature.

 PlanetMath: tree
Such trees are typically drawn with the root at the top of the diagram, with all other nodes depending down from it (however this is not always the case).
Given this parent-child relationship, a descendant of a node in a directed tree is defined as any other node reachable from that node (that is, a node's children and all their descendants).
Therefore a forest or a tree is often used as a data structure.

 B-tree - Wikipedia, the free encyclopedia
Starting at the root, the tree is traversed top to bottom, choosing the child pointer whose separation values are on either side of the value that is being searched.
This depth will increase slowly as elements are added to the tree, but an increase in the overall depth is infrequent, and results in all leaf nodes being one more hop further removed from the root.
In computer science, B-trees are tree data structures that are most commonly found in databases and filesystems.

 B-Trees
B-trees are balanced trees that are optimized for situations when part or all of the tree must be maintained in secondary storage such as a magnetic disk.
To ensure that the height of the tree is as small as possible and therefore provide the best running time, a balanced tree structure like a red-black tree, AVL tree, or b-tree must be used.
Since the "branchiness" of a b-tree can be large compared to many other balanced tree structures, the base of the logarithm tends to be large; therefore, the number of nodes visited during a search tends to be smaller than required by other tree structures.

 Save The Pacific Northwest Tree Octopus
Tree octopuses became prized by the fashion industry as ornamental decorations for hats, leading greedy trappers to wipe out whole populations to feed the vanity of the fashionable rich.
Other tree octopus species -- including the Douglas octopus and the red-ringed madrona sucker -- were once abundant throughout the Cascadia region, but have since gone extinct because of threats similar to those faced by paxarbolis, as well as overharvesting by the now-illegal tree octopus trade.
The reproductive cycle of the tree octopus is still linked to its roots in the waters of the Puget Sound from where it is thought to have originated.

When a B+ tree is implemented on disk, it is likely that the leaves contain key, pointer pairs where the pointer field points to the record of data associated with the key.

Another variant is the B* tree, which is very similar to the B+ tree, but tries to keep the nodes about two-thirds full at a minimum.
