another little look at Cefn Bryn

I spent an hour and a half on Cefn Bryn in the rain on Saturday and recorded 53 species in an area of flushed ground to the north of Arthur's Stone.  Kurzia pauciflora was more frequent here than I've seen elsewhere on Gower, typically growing through mounds of Sphagnum papillosum. Amongst eight Sphagnum, tenellum was the only species of any note.

I only came across one base-enriched flush, where there were small quantities of Palustriella falcata and Sarmentypnum exannulatum mixed in the short turf, which held frequent Campylium stellatum and Scorpidium cossonii.

Grimmia trichophylla & Racomitrium heterostichum were present on several of the rocks in the area, surprisingly this being the first time the latter has been recorded on the Gower peninsula.

  1. Lovely photo of the Kurzia. Some of those Gower tetrads must have very respectable totals by now.

  2. Out of interest, was that R. heterostichum s.s? R. affine might be more expected in that habitat.

  3. Good shout and just checked (see extra photo), but with 8 cells across adaxial surface of the costa and cross section showing ~2 layers of cells, this seems to fit heterostichum using Smith. Any more comments welcome, sorry section pic is a bit soft.

  4. No quibbles there; the costa you demonstrate is very typical being wide as well as canaliculate. I find I can see the thicker and narrower nerve of R. affine in the field now but I still need to check at least once in every tetrad. Still, it's a relatively easy leaf to section and mine aren't always as complete as you've obtained.
