Comment
Aids plant in climbing. May be branched, may have adhesive disks at its distal end, may be woody, and may bear small leaves. A stem apex tendril differs from a branch tendril in that it arises from the shoot apical meristem, rather than in an axil. However, a shoot apex tendril may arise either from the apex itself, in which case it is terminal, or from the side of an apical meristem, in which case it is a lateral structure. In the latter case, the main stem of the plant undergoes sympodial growth. A stem apex tendril is often located on the opposite side of a stem from a leaf at the same node, as in Vitaceae. See also leaf tendril (PO:0025361), leaflet tendril (PO:0025362), leaf apex tendril (PO:0025363), branch tendril (PO:0025364), leaf rachis tendril (PO:0025366), and prophyll tendril (PO:0025365). Careful observation is required to correctly classify some tendrils.
