Flower and fruit anatomy of Cordia nodosa Lam. and Varronia bonplandii Desv. (Cordiaceae, Boraginales) with phylogenetic implications

Despite their ecological importance and wide distribution, Cordiaceae have not been subject to detailed anatomical study yet. We examined flower and fruit anatomies of Cordia nodosa and Varronia bonplandii (using paraffin sectioning and light microscopy) in comparison with other woody members of Boraginales. The internal architecture of the superior bicarpellate ovary resulted from the development of secondary septa including apical, basal and...
