About eucalyptus pollen
Angular, three-cornered pollen from planted gum trees.
Plants that produce it
- Red gum, blue gum and other landscape eucalypts
- Windbreak and street plantings in warm dry cities
How to recognize it
Small, distinctly triangular grain with the three furrows set at the corners and a smooth wall — the outline alone is usually diagnostic.
Typical published size: 18–28 µm
Commonly confused with
- Sedge pollen — triangular but with pores, not corner furrows
Allergy relevance
Weakly to moderately allergenic; mostly insect-pollinated, so airborne counts stay modest even near large trees.
