Alternate intervessel pits showing pit borders and pit apertures in the wood of Petersianthus macrocarpus (Lecythidaceae). Lens et al. report that several wood features, including among others vessel pits, type of vessel perforation and the structure of the rays, are phylogenetically informative at the subfamily level. See "A search for phylogenetically informative wood characters within Lecythidaceae s.l." American Journal of Botany 94(4), pp. 483-502.
