The trunk of a tree, usually the portion below the lowest branch. Compare canopy. bostrychoid Arranged on a conical surface (like a snail shell); used to describe inflorescence s in which the bud s are arranged in an almost helical manner on the outside of a long, tapering, conical rachis. bract
Prop-roots – In some dome-shaped (deliquescent) trees, from the mature horizontal boughs (stem-branches) some quite thick (millimeters to centimeters) roots come down. After growing and reaching the ground, they establish more elaborate root branches as well as show massive secondary thickening. Thus, they start to resemble the main trunk.
Other words for twig include branchlet, spray, and surcle, as well as the technical terms surculus and ramulus. Branches found under larger branches can be called underbranches. Some branches from specific trees have their own names, such as osiers and withes or withies, which come from willows.
Although "tree" is a common word, there is no universally recognised precise definition of what a tree is, either botanically or in common language. [ 1 ] [ 2 ] In its broadest sense, a tree is any plant with the general form of an elongated stem, or trunk, which supports the photosynthetic leaves or branches at some distance above the ground ...
The crown of a woody plant (tree, shrub, liana) is the branches, leaves, and reproductive structures extending from the trunk or main stems. Shapes of crowns are highly variable. The major types for trees are the excurrent branching habit resulting in conoid shapes and decurrent (deliquescent) branching habit, resulting in round shapes. Crowns ...
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). [1]
A twig is a thin, often short, branch of a tree or bush. [1] The buds on the twig are an important diagnostic characteristic, as are the abscission scars where the leaves have fallen away. The color, texture, and patterning of the twig bark are also important, in addition to the thickness and nature of any pith of the twig. [2]
All the branches of a tree at every stage of its height when put together are equal in thickness to the trunk [below them]. [39] A more general version states that when a parent branch splits into two or more child branches, the surface areas of the child branches add up to that of the parent branch. [40]
