Abstract Wood anatomy of Melicope ternata, M.
simplex, and Phebalium nudum is described. In M. simplex and
M. ternata vessels have no helical thickenings, most perforation plates
are simple but some are scalariform or reticulate, grooves connect pit
apertures, and vessel to ray pits are sometimes unilaterally compound.
Disjunctive ray and axial parenchyma cells are present. Melicope simplex
is distinguished from M. ternata in having narrower rays, more
disjunctive ray cells, and narrower boundary bands of axial parenchyma. The
vessel elements of P. nudum have helical thickenings and simple
perforation plates, and lack unilaterally compound pits. Disjunctive axial
parenchyma cells are absent and disjunctive ray cells are rare. Boundary axial
parenchyma and rays are usually only 1-2 cells wide. Vasicentric tracheids are
common in P. nudum but rare in M. simplex and M. ternata.
Silica bodies occur in the parenchyma cells of all three species.
