Having two sides or margins in a symmetrical arrangement, often used in botany to describe plant structures.
From 'bi-' (two) plus Latin 'collateralis' (from 'col-' meaning together plus 'latus' meaning side). The term emerged in botanical science to describe bilateral symmetry.
Bicollateral vascular bundles in plants are evolutionary engineering marvels—they allow nutrients to flow in two directions simultaneously, giving plants like pumpkins and beans extra transport efficiency that single-sided systems can't match.
