Wood is typically thought of as stiff and rigid, but some wood, in the race upward to access the best sunlight, twists. Lianas, or woody vines, are concentrated in tropical forests; they possess a narrow stem that lets them climb to the top of the canopy, more than 100 feet above the ground, as quickly as possible by twisting their way around tree trunks. Basking in the sun at the top, these vines flower, fruit and lay out new leaves as they photosynthesize.
