Eucalyptus is a large genus with so many species often difficult to
separate, but here are tips to separate them

E. citriodora are rather distinct from others in strongly scented (more
like odomos) leaves when crushed, flower buds almost as long as broad, cap
pinkish, hemispherical and cup like with sunkun disc.

E. camaldulensis has similar shaped flower buds but light brown and not
pinkish cap which is distinctly pointed, fruit has 4-5 slightly raised
teeth in the center.

E. microtheca has narrow leaves forming dense drooping canopy, buds very
small usually less than 5 mm long, pointed at tip, fruits barely 3-4 mm
long with 3-3 spreading teeth longer than base.

E. tereticornis buds are longer, often up to 1.5 cm long, cap much longer
than base and gradually tapered, fruit with 4-5 teeth, projecting upwards
almost as long as base.

E. globulus has usually single large flower, fruit more than 20 mm across

E. Polyanthemos is very distinct in its almost rounded leaves, flowers in
panicles and hemispherical cap

E. leucoxylon with usually 3-flowered clusters, on up to 12 mm long
peduncles, conical cap, as long as base, fruit 10-12 mm across.

I hope that helps.
