Adaptations for climbing

(Appendages or modifications which may or may not be involved in climbing.)

L107 stems and/or branches twining

L108 tendrils present

Tendrils present on the twigs, small branches, leaves, stipules or petioles. Tendrils can take on various forms and may be modifications of a number of other organs, e.g. inflorescences, branches, petioles, stipules etc.

L109 hooks or spines present

Hooks or spines present on the twigs, branches, leaves or other vegetative organs. These hooks or spines may or may not be involved in the climbing process.

L110 branches otherwise obviously modified

Branches obviously modified, but not forming tendrils, hooks or spines. This is a modification which is sometimes associated with the climbing habit and in such cases the branches project backwards so that the angle in the axil exceeds 90 degrees.

L111 adventitious roots or haustoria present

Adventitious roots or haustoria produced by the twigs and small branches. This feature is developed by some vines to facilitate climbing, particularly in their juvenile stages.
