15. county. It is an area of freshwater marsh dissected by the River Blackwater, just west of the picturesque village of Feering. The western side of the river is a mature cricket bat willow plantation of 10 acres or so, intersected by a dyke. Other vegetation of that area includes reeds, sedges, alders and a few large trees of various species. The eastern bank of the river is a smaller wetter area, bisected in almost equal parts by a footpath. South of the path is a very wet reedbed with a few "islands" of willow scrub. North is a dryer reedbed gradually losing area to grasses, nettles, cow parsley and willow herb. The flora of the total reedbed area includes some very interesting marsh plants. One of the earliest to flower, which this spring spent some days completely submerged is the marsh marigold or Kingcup (Caltha Palustris). This plant resembles a large buttercup. One of the most impressive flowers of the reed-bed is the Yellow Iris (Iris Psendomus) the huge yellow flower contrasting sharply with the uniform grey-green of the reed—bed. Bullrishes also abound. A ditch on the edge is often choke by Watercress (Nasturtium officinale), the favourite habitat of the water shrew. Along the river, Yellow Water Lilies (Nuphar lutea) and my favourite, the bright blue water forget-me-not (Myosotis scorpioides) were both in flower last June. Slightly earlier in the season I discovered a single plant of Cuckoo Flower (Cardomine pratensis) an uncommon member of the cabbage family, usually associated with water meadows. ---oOo---
