Brecknock, v.c. 42

Following Government guidance and in the interests of health and safety, this year's field meetings are cancelled with immediate effect and until further notice. For further information please contact your County Recorder(s).

Brecknockshire is an interesting vice county in several respects. It contains the most southerly land over 800m in the UK. There is limestone with characteristic sinkholes and pavements on the southern border. In the north the vice county stretches into the Cambrian Mountains and includes parts of the Elan Valley, drained by acid streams and bogs. Much of the eastern boundary lies along the River Wye and the county also contains most of the upper and middle catchment of the River Usk. The north-western border follows the Tywi (River Towy) that flows south and then west through Carmarthen to the sea. Further south the county extends into possibly the most remote-from-roads land in England and Wales on the back of the Black Mountain (not to be confused with the Black Mountains in the south east of the county!). Wet meadows are still reasonably common along many of the tributaries of the rivers. Llangors lake at the Northern limit of the National Park is the largest completely natural lake in Wales and it is surrounded by both hay meadows and marsh. A high proportion of county Rare Plant Register species grow there.

The heights of the Central Beacons may at first seem devoid of much botanical interest but the very steep northern slopes host a variety of interesting species including Sea Campion, Gludlys arfor, Silene uniflora; Dwarf Willow, Helygen fach , Salix herbacea; Purple saxifrage, Tormaen porffor , Saxifraga oppositifolia; Rock (or Welsh) Stonecrop, Briweg Gymreig, Petrosedum forsterianum and Serrated Wintergreen, Glesyn-y-gaeaf danheddog, Orthilia secunda. Limestone escarpment in the south east is host to populations of Angular Solomon's-seal, Llysiau-Solomon persawrus, Polygonatum odoratum and Hutchinsia, Beryn y graig, Hornungia petraea. There are also many rare Hieracium, Sorbus and Taraxacum species in the county, some endemic. Many species are found at or near their highest known altitude occurrence in the county, for example Mistletoe, Uchelwydd, Viscum album and Marsh Fern, Rhedynen y gors, Thelypteris palustris.

Persicaria mitis, Y dinboeth ddi-flas, Tasteless Water-pepper. Found on a casual walk in August. This was not quite a first for the county as A E Wade had recorded it down in the far south west of the county in 1927 – with no records since.

Greater Broomrape, Gorfanhadlen fawr, Orobanche rapum-genistae. This turned up near Brecon. Occurrences are sporadic in the county.

Little Mouse-ear, Clust-y-llygoden fach, Cerastium semidecandrum. Found in 2018 by Ray Woods but the first opportunity to photograph the flower was in 2019.

Thelypteris palustris (Marsh Fern) at possibly its highest altitude in the country. Army permission was needed to search for it.
