A twining vine, also known as a '''bine''', is one that climbs by its shoots growing in a [[helix]], in contrast to vines that climb using tendrils or suckers. Many bines have rough stems or downward-pointing bristles to aid their grip. [[Humulus|Hops]] (used in flavoring beer) are a commercially important example of a bine.<ref>[http://www.merriam-webster.com/dictionary/bine ''bine''] at [[Merriam-Webster]]</ref><ref>[http://www.wweek.com/portland/article-25406-cone-heads.html Cone Heads] at ''[[Willamette Week]]''</ref>

The direction of rotation of the shoot tip during climbing is autonomous and does not (as sometimes imagined) derive from the shoot's following the sun around the sky – the direction of twist does not therefore depend upon which side of the equator the plant is growing on. This is shown by the fact that some bines always twine clockwise, including runner bean (''[[Phaseolus coccineus]]'') and bindweed (''[[Convolvulus]]'' species), while others twine anticlockwise, including black bryony (''[[Dioscorea communis]]'') and climbing honeysuckles (''[[Lonicera]]'' species). The contrasting rotations of bindweed and honeysuckle was the theme of the satirical song "Misalliance", written and sung by [[Flanders and Swann|Michael Flanders and Donald Swann]] (but the lyrics confuse the direction of twining, describing honeysuckle as right-handed and bindweed as left-handed).<ref>[https://www.flashlyrics.com/lyrics/flanders-and-swann/misalliance-72 Misalliance]</ref>
