A couple of options:
with(mod, text(Species, Dplus, label = rownames(dune),
pos = 2, cex = 0.7))
fiddle with pos - see ?text for details.
Another option is
with(mod, identify(Species, Dplus, label = rownames(dune), cex = 0.9))
where you now click around the points you want to label. See ?identify
for further details.
