    Just wondering if anyone recognizes this plant, presumably a perennial?

    It was growing right beside the sea but in an area of freshwater seepage, near Dashing Rocks, Timaru, New Zealand. Regrettably, although there were some advanced buds and flower stems, none of the flowers were open. The largest leaves and petioles had a combined length of around 25cm.

    Any ideas?

    Perhaps Alisma.

    Well done, thank you. I'm familiar with Alisma gramineum but its flower stems tend to be shorter than the foliage. This looks to be Alisma plantago-aquatica, which has certainly been recorded in the area.
