English term or phrase: venation

Definition from planandplant.com:
the arrangement of the veins in leaves and petals. Trees that are simliar in other characteristics can identified by the patterns of the veins in their leaves.

Example sentence(s):

In pinnate venation, the veins extend laterally from the midrib to the edge, as in apple, cherry and peach. Palmate venation occurs in grape and maple leaves, where the principal veins extend outward, like the ribs of a fan, from the petiole near the base of the leaf blade. The University of Arizona
Parallel venation occurs in the leaves of nearly all monocotyledonous Angiosperms, whose embryos have one cotyledon, as in flowering plants such as lilies and grasses. Net Industries
Recent work has shown that this diversity in venation has consequences for leaf and whole-plant hydraulic capacity, for leaf biomechanical support, and for leaf tolerance of vein damage. eco.confex.com

nervatuur

Definition from Houtwal.be:
Nervatuur is het geheel van de nerven of bladaders .

Example sentence(s):

De nervatuur van een blad zorgt enerzijds voor de versteviging van het blad en anderzijds voor de aanvoer van water en voedingsstoffen en de afvoer van assimilaten. De nerf bestaat uit twee soorten weefsels: floëem en xyleem. Het floëem bevindt zich aan de onderzijde van de nerf en verzorgt de afvoer van assimilaten. Het xyleem ligt daarbovenop en zorgt voor de aanvoer van water en daarin opgeloste voedingsstoffen. Het floëem en xyleem wordt voor de versteviging omgeven door dicht parenchymatisch weefsel en collenchym. - Wikipedia
Het verloop van de nerven in een blad noemen we nervatuur. Er zijn drie verschillende typen te onderscheiden. Veernervige bladeren hebben één hoofdnerf. De zijnerven verlopen vanaf de hoofdnerf naar de bladrand. Bij handnervige bladeren vertakt de hoofdnerf zich aan de voet van het blad in meerdere even dikke nieuwe hoofdnerven. Bij parallelnervige bladeren lopen alle nerven evenwijdig (parallel) aan elkaar. - Biodoen
