In biological phylogenetics, a clade (from Ancient Greek κλάδος (kládos) 'branch'), also known as a monophyletic group or natural group, [1] is a grouping of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree.

Branch attachment. A branch attachment is where a branch is attached to the trunk of a tree. Three types of branch attachment are recognized due to differences in the anatomical position of buds that form them. Two key components contribute to the mechanical strength and toughness of the attachment: interlocking wood grain at the top of the ...
A branch collar is the "shoulder" between the branch and trunk of woody plants; the inflammation formed at the base of the branch is caused by annually overlapping trunk tissue. [1] The shape of the branch collar is due to two separate growth patterns, initially the branch grows basipetally, followed by seasonal trunk growth which envelops the ...
Inosculation. 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/against" or etymologically and more illustratively "to make a small mouth inward ...
The leaves are variable, being 15–25 mm (5 ⁄ 8 –1 in) long and flat on young trees and shaded lower branches in older trees. The leaves are scalelike, 5–10 mm ( 1 ⁄ 4 – 3 ⁄ 8 in) long on shoots in full sun in the upper crown of older trees, with a full range of transition between the two extremes.
