Dichotomous leaf venation
WebMonocots have parallel venation; the veins run in straight lines across the length of the leaf without converging at a point. In dicots, however, the veins of the leaf have a net-like appearance, forming a pattern known as reticulate venation. One extant plant, the Ginkgo biloba, has dichotomous venation where the veins fork. WebThe leaf venation system can influence leaf and whole-plant hydraulic conductance (K leaf and K plant respectively; 12–15). Under a given transpiration rate, K plant, which is constrained by K leaf, determines the degree to which stomata may remain open, thus limiting gas exchange and plant growth (14, 16). K leaf is in

Venation is the phenomenon of arrangement of veins in the lamina of the leaf surface. It is of three types, reticulate, parallel and furcate venation. In reticulate venation, veins form the network like structure. For example, leaves of dicot plants. In parallel venation, veins arise from the mid rib and run parallel.
