Abstract

In order to amplify and correct information in the literature, qualitative and quantitative data are presented for wood, root, stem, and leaf anatomy of the two species of Eupomatia. Perforation plates of vessel elements have many bars and variously extensive remnants of pit membranes; imperforate tracheary element's are septate fiber-tracheids with reduced borders on pits; axial parenchyma is diffuse and sparse. Reports of storying and vesturing in wood of Eupomatia are probably incorrect. Tuberous roots have furrowed xylem and highly parenchymatous secondary phloem. Nodes are multilacunar. Tannin-like structures in stems and petioles are cellular rather than ducts or cavities. Stomata are paracytic. The two species are compared. Eupomatiaceae are placed in Magnoliales (sensu stricto) in recent studies. Vegetative anatomy confirms that placement, but, as in previous studies, this study cannot decisively place the family close to any one family of Magnoliales.
