Дефиниција: veins run parallel and equidistant to each other for most of the length of the leaf; they may converge or fuse (anastomose) towards the apex
Дефиниција: secondary vascular tissues with large amounts of softer storage cells (i.e. parenchyma) mixed with the wood or xylem cells. The stems of these plants are softer than the wood of trees we use for lumber.
