    We saw this mat of small heart-leaved plants yesterday floating in a stream off the road from Maple Falls to Mt Baker, and can't figure it out from "Plants of coastal British Columbia" by Pojar & MacKinnon, or "Flowering Plants of Swap & Waterway" by Lewis Clark.

    Watercress (Nasturtium officinale), I guess.
