   Marginal leaf glands

I have been undertaking an anatomical study of two species of
Eucalyptus (Myrtaceae) that have glands on the margins of their
leaves.  The glands are black, about 1-2mm across and are easily
visible with the naked eye. The glands give the leaf margin a
denticulate appearance.  The anatomy is unusual, in that they look
like lenticels with a cambium producing cells filled with phenolics.

I am interested if anyone knows of any other species that have this
structure (or something similar).  As you can imagine it is
practically impossible to search through descriptions of all known
species, so I would very much appreciate if anyone could help.
