Botanical classification: Class Magnoliopsida; Order Poales; Family Gramineae.
Common name: Perennial ryegrass.
Pollen type: Gramineae.
Comparison remarks: Single pore with thickened border. Cereal grasses (maize, wheat, oats etc.) generally have larger pollen than pasture and wild grasses.

Aperture type: pores only. Surface pattern: smooth or indefinite. Exine section: thin to medium (no rods visible). Other structural features: thickened or projecting edges to apertures.
