Stem

Simple botanical illustration of a single upright plant stem shown in side view as a straight to gently tapering cylindrical axis, green in a young herbaceous form or brown to brownish-green in a more mature form. The outer surface is smooth to slightly ridged, firm but flexible, and unbranched or with only very subtle leaf, bud, or small branch attachment points. Visible nodes appear as slight swollen rings or segment marks dividing the stem into short to moderate internodes. The base may be slightly thicker than the upper end. No leaves or surrounding plant parts are attached, presenting the stem as an isolated reusable botanical component.
