In botany, describing a plant or tree whose vascular bundles (the tubes that transport water and nutrients) are arranged throughout the roots rather than concentrated in a central structure.
From 'bundle' (a bundle of vascular tissue) plus 'rooted' (having roots). This botanical terminology emerged in the 19th century as scientists developed more detailed understanding of plant anatomy.
Bundlerooted plants like monocots (grasses, corn, palms) have fiber-like roots that spread more efficiently through soil than the 'taproot' system of dicots—this is why grass doesn't have one deep root like a carrot does!
