Having two vascular bundles or systems of vessels for transporting fluids; used in botany and anatomy.
From Latin 'bi-' (two) + 'vascular' (relating to vessels), from 'vasculum' (a small vessel). The term emerged in 19th-century botany to describe plant tissues.
Some plant leaves are bivascular—they have two separate xylem and phloem systems running through them! This double plumbing system gives the leaf extra structural strength and transportation capacity.
