Bundle scar – a small mark on a leaf scar indicating a point where a vein from the leaf was once connected to the stem. Caudex – the hard base produced by herbaceous perennials, which serves in overwintering the plant. Caulescent – with a distinctive stem.

One leaf, branch, or flower part attaches at each point or node on the stem, and leaves alternate direction—to a greater or lesser degree—along the stem. Basal Arising from the base of the plant. Cauline Attached to the aerial stem. Opposite Two leaves, branches, or flower parts attach at each point or node on the stem.
Prickles on a blackberry branch. In plant morphology, thorns, spines, and prickles, and in general spinose structures (sometimes called spinose teeth or spinose apical processes), are hard, rigid extensions or modifications of leaves, roots, stems, or buds with sharp, stiff ends, and generally serve the same function: physically defending plants against herbivory.
The stems of Athrotaxis are covered with small flat pointed leaves called "scale leaves" or "cataphylls".. In plant morphology, a cataphyll (sometimes also called a cataphyllum [1] or cataphyll leaf [2]) is a reduced, small leaf. [3]

With an opposite leaf arrangement, two leaves arise from the stem at the same level (at the same node), on opposite sides of the stem. An opposite leaf pair can be thought of as a whorl of two leaves. With an alternate (spiral) pattern, each leaf arises at a different point (node) on the stem. Distichous leaf arrangement in Clivia
