I had to take someone for a regular appointment at Singleton Hospital today so, rather than spending my time in the waiting room, I took a short walk in the adjacent Singleton Park and the grounds of the university. There has been some clearance within the wooded gardens immediately north of the university, and I chanced upon about half-a-dozen plants of small balsam Impatiens parviflora, a particularly unspectacular member of the balsam family (photo of flower below). I estimate the grid ref to be SS631921 and it was found along a path some 20ft or so approximately westwards of a large clump of Gunnera, and with a large man-made decorative rock outcrop in the background (in case anyone wants to re-find it).
Elsewhere in the park, I noticed water bent Polypogon viridis (a grass that is rapidly spreading in the Llanelli area of SE Carmarthenshire) and grey sedge Carex divulsa, the latter at the base of railings edging a pathway where the university grounds meets the hospital to the west.
It was good to see the more biodiversity-friendly management of the park grounds, with areas of uncut grass (presumably to be cut, hay-meadow style, in due course) and sizeable dead tree stumps which will provide a niche for deadwood invertebrates. Full marks to the park authorities!...and I wish that Carmarthenshire would do the same, rather than removing old trees in public areas, with sometimes very dubious justification.
