A leaf venation pattern characterized by a network of interconnected veins that branch and rejoin, forming a net-like pattern. This venation type is typical of dicotyledonous plants.
From Latin 'reticulum' meaning 'little net' (diminutive of 'rete' meaning 'net') combined with 'venation.' The term was coined in the 19th century as botanists developed precise vocabulary for describing leaf architecture.
Reticulate venation creates biological redundancy - if one vein gets damaged, the interconnected network can still transport materials around the blockage! It's like having multiple alternate routes on a highway system.
