Tree trunks They are robust stems, developed at the bottom and branched at the apex.
They are found in most trees and shrubs of the dicotyledonous group.
Stipes they are usually unbranched stems, which present at their apex a tuft of leaves. They are typical of palm trees.
Culms they are unbranched stems that are distinguished from the stems by presenting, in all their extension, sharp division into buds. Thatched buds can be hollow like bamboo or full like corn or sugar cane.
Climbing Stems they are present in climbing plants and grow wrapped around various types of support. This type of stem represents an adaptation to obtain brighter places where there is more light for photosynthesis.
