Abstract

Microfibrillar webs traversing the pit apertures on the lumen side of vessel member walls were observed in Coriaria arborea Lindsay, Corynocarpus laevigatus J. R. et G. Forst., and Knightia excelsa R. Br. These webs originate from a layer of wall material occurring on top of the normal secondary wall.
