A note on refinding Carex pauciflora in Montgomeryshire (v.c.47), G. & P.Foulkes

If hybridisation events are not overly rare at Cae Blaen-dyffryn then it is perhaps a small coincidence that the capsule chosen proved to contain hybrid seed, conceived in v.c.44 but borne in v.c.46 on this occasion, strangely, though such liaisons cannot be uncommon between plants along vice county boundaries. My thanks go to Richard Pryce for encouraging me to write this note.

A note on refinding Carex pauciflora in Montgomeryshire (v.c.47)

Gill and Peter Foulkes (GF is BSBI v.c.47 Joint Recorder) Rather late in Summer 2021, we decided to look for a record from 2000 of Carex pauciflora (Few-flowered Sedge) on Trannon Moor, near Carno. This rather inconspicuous species is found in acid raised and blanket bog often growing on and around old Sphagnum (Peat Moss) hummocks (NVC M2 Sphagnum cuspidatum (Feathery Bog-moss)/recurvum (Recurved Sphagnum) bog pool community) (Averis et al., 2004). It occurs throughout the Highlands and Outer Isles, Northern Scotland, the Lake District and North Pennines. The only records in Wales are from Montgomeryshire (v.c.47) and Caernarfonshire (v.c.49). In A Vascular Plant Red Data List for Wales (Dines, 2005) it is listed as CR (Critically Endangered), with less than 50 individual plants and reaching the southern edge of its British distribution.

We found it growing in two small depressions, on Sphagnum, in peaty mire (probably with less than 20 plants in total) at almost identical grid refs to the records from 2000. Associates included: Andromeda polifolia (Bog-rosemary), C. magellanica (Tall Bog-sedge), Drosera rotundifolia (Round-leaved Sundew), Eriophorum angustifolium (Common Cottongrass), Narthecium ossifragum (Bog Asphodel) and Erica tetralix (Cross-leaved Heath).
