Abstract
Qualitative and quantitative wood anatomical data are given for two narrow Queensland endemic Eucryphia species, E. wilkiei B.Hyland and Eucryphia jinksii P.I.Forst. Comparisons of wood anatomy of all extant Eucryphia taxa show that E. jinksii and E. wilkiei are distinct from each other, and other Eucryphia species. However, for both species characters relating to perforation plates, helical thickening (E. wilkiei only) and fibres are shared with the South American species, whereas the presence of crystals in the axial parenchyma is shared only with the Australian species. These data suggest that, based on wood anatomy, E. jinksii and E. wilkiei are basal among Australian species.
