Abstract
The Mesozoic fossil wood assemblage, the Protopinaceae, have a type of pitting on the radial walls of their tracheids that is now almost extinct. Until now, the proposed explanations for this type of pitting were unsatisfactory. New observations show a connection with tree architecture, and a new hypothesis is proposed. Key words: Protopinaceae, Gymnosperms, Mesozoic, anatomy, architecture, morphology.
