Title: The relationship between histological structure and chemical composition in leaves of forage grasses and legumes A study was conducted to determine the relationship between histological structure and chemical composition in leaf blades of the forage grasses Bouteloua repens and Bothriochloa pertusa and of the legumes Stylosanthes scabra, Desmodium barbatum and Tephrosia cinerea. In grasses and during the dry season, sclerenchyma content of B. pertusa increased by 197.8%, and variation in this parameter explained 64% of the variation observed in in vitro dry matter digestibility (IVDMD, P
