September 6th Banks of River Wye

The Monmouth meeting under the informed leadership of Heather Colls had a riparian theme as we explored river banks on both sides of the English/Welsh border. Six members met the leader near Dixton churchyard for a gentle walk upstream along the right bank of our first river, the Wye (Afon Gwy). Here the very plentiful Impatiens glandulifera (Himalayan Balsam) did not out-compete other species. Tanacetum vulgare (Tansy) and Mentha suaveolens (Round-leaved Mint) were flowering well, the latter recognised by its roundish leaves with the teeth bent under to appear blunt. Patches of yellow here and there indicated a second flush of flowers on Brassica nigra (Black Mustard) and Raphanus raphanistrum ssp. raphanistrum (Wild Radish) each with their characteristic fruits. In the shallow water of the river’s margin we spotted several dozen flowering stems of Butomus umbellatus (Flowering Rush).

At a point where we could actually get down to the water’s edge we found Mentha x verticillata (Whorled Mint), Myosoton aquaticum (Water Chickweed) and Achillea ptarmica (Sneezewort) on the bank and Elodea canadensis (Canadian Waterweed), Potamogeton perfoliatus ( Perfoliate Pondweed) in the water. Ranunculus aquatilis (Common Water-crowfoot) grows here in quantity and Heather described to us how the surface of the water is turned white when the plant is in flower.

We retraced our footsteps stopping to admire a splendid many-trunked Tilia cordata (Small-leaved Lime) growing out of the churchyard wall and spotting Ceterach officinarum (Rustyback) growing on the wall on the other side of the lane.
