Anthoceros punctatus in Ystradgynlais

Found in disturbed pasture today and wonder if this might be new for vc42? Voucher retained if necessary. Horns still 'in bud', but plenty ripe antheridia on view...

  1. Nice record Barry.
    In The Mosses and Liverworts of Brecknock, Ray Woods describes one record (1995) for A. punctatus from the north of Brecs (below Craig Cwerfu) in a location that sounds very much like the Afan Forest Park site. He also notes that a specimen lodged in the NMW collection was collected in 1926 either from the Brecon Beacons or 'along the Usk and Abergavenny Road below Brecon'.
    I have also noted recently that A. punctatus was recorded in VC41 by Appleyard (BBS) on a damp track by Burry Pill in 1963 (Trans BBS, 1964), which means that the Afan Forest Park record was not a new county record either. Appleyard's record does not appear to be supported by a specimen (as far as I am aware) which may be why Roy didn't include it in the Flora of Glamorgan.

  2. Thanks for these extra detsils Charles. It seems our predecesdors left a trail of breadcrumbs, which if you have the skills of Hercule Poirot, can lead to a treasure trove of information.

  3. Hi Barry,

    A. punctatus in vc42 is a bit of a mystery as it is not shown for the county in the Census Catalogue - perhaps Ray has a specimen from the 1996 location? I haven't had the opportunity to search through the NMW collection yet, but I expect Nicholson's specimen would still be present. Charles' comment about this record reminded me of some diary entries of Nicholson's from 1926, when he journeyed from Lewes in Sussex and met up with H Knight, F Woodbridge and Miss Armitage in Brecon, from where they toured Brecks and further north (Knight was lucky enough to have a car) - he mentions the Anthoceros on a "new bank" of the Usk 5-6 miles along the road to Abergavenny, which I guess must have been the Pencelli area where there are still nice big meanders and oxbows to this very day.

    If yours is good material I would submit the specimen as a vc voucher.

    I'll have to try and keep the momentum going in Brecks - so far in 2018, visiting bryologists are averaging over 1 new species per month for the county!

  4. Yes, specimen is good enough for a voucher. I'll see who is curator for Hornworts and post on while fresh...
