Abstract :
The present study examines variations in the timing of flowering between populations of Iberian Poaceae species using pollen data from 12 sites in Spain. The spatial variation in pollen season start-date for any given year was around 1 month; year-on-year differences at any given site ranged around 1.5 months. The spatial variation in the pollen season peak-date was smaller, at around 15 days, while the year-on-year variation for the peak-date at a given site was never greater than 20 days.
