Modified Scalariform and Reticulate Perforation Plates in Species of Euodia (Rutaceae)

Abstract

Although there have been some reports of occurrence of scalariform and modified scalariform types of perforation in vessels of some members of the Rutaceae, no such observation has so far been made in the woods of Euodia species. In two species, E. elleryana and E. lunuankenda, besides the scalariform type, irregular and regular reticulate types of perforation have been observed. Additionally, silica bodies have also been noticed in vessels, fibres and axial parenchyma.
