Abstract
Vessels in some species are connected by intervessel pits on the tangential walls of radial multiples, which may allow the radial flow of sap. This network was investigated in Machilus thunbergii Sieb. et Zucc., a diffuse-porous wood with radial multiples extending through growth ring boundaries. Air permeability measurements suggest radial flow paths exist through a growth ring boundary. Flow paths were pressurestained with reduced basic fuchsin solution. Observations of serial cross sections confirmed the flow paths to be via vessels and intervessel pits in radial multiples of vessels on growth ring boundaries. Resin casts of low-density polyethylene, viewed by scanning electron microscopy, showed the vessel network extending through a growth ring boundary as well as the branching of vessels.
