IGNS collection number: NZGS4690, NZGS4692.
Botanical classification: Class Magnoliopsida; Order Myrtales; Family Myrtaceae.
Common name: Eucalypts, gum trees.
Pollen type: Eucalyptus type.
Comparison remarks: There is some variation between pollen of various species of Eucalyptus and the related genera Corymbia and Angophora. The pollen resembles that of Metrosideros in having a triangular "island" of exine where the furrows join at the poles, but is commonly larger or with more coarsely patterned exine and appears to have thicker exine around the pores.
Morphology (unacetolysed pollen): Size class: very small (<20 μm), or small (20-30 μm). Shape in equatorial view: flattened oval (oblate). Shape in polar view: triangular/rounded triangular. Aperture numbers: 3. Aperture type: furrows with pores, or united or irregular furrows. Surface pattern: smooth or indefinite, or granular. Exine section: thin to medium (no rods visible). Other structural features: thickened or projecting edges to apertures.
Bee pollen pellet colour: White to light yellow (Walsh 1978).
