Out with the experts

I've been out with experts recently - so this blog features more than just the vascular plant world thanks to them.

But first the botany group were at Henallt Common because it hasn't actually been comprehensively recorded that recently. We recorded 120 species - and will revisit in spring / early summer to jack that total up a bit. But of course the "Naked Ladies" were the star attraction...
Meadow Saffron, Saffrwm y ddôl or Colchicum autumnale
(Some call them Naked Ladies)

The Rowans were very heavy with berries:
Rowan, Criafolen or Sorbus aucuparia

Then I visited the church at Llanfaes as Keith Noble had alerted me of a Broomrape population there. It is the same species as already established around Brecon Hospital - so has now apparently spread over the Usk.
Ivy Broomrape, Gorfanhadlen eiddew or Orobanche hederae
(A parasitic plant living, in this case, on Atlantic Ivy roots.)

Then I joined Steph from Brecknock Wildlife Trust and Hannah from the Freshwater Habitats Trust on Llangorse Lake where I was introduced to these:
Water Spider or Argyroneta aquatica

Lake Limpet or Acroloxus lacustris

And I did manage to confirm (with the help of the referee for Charophytes, Nick Stewart) that Llangorse has Nitellopsis obtusa amongst its vegetation. I didn't get any photographs - in fact I only just managed to get a suitable specimen off to be verified as the samples disintegrated around me. See pictures of the (very primitive) plant here: German site with pictures of Nitellopsis obtusa

Then Steph and I met up with plants-man extraordinaire, Andy Shaw at Brechfa to assess the Crassula invasion which was somewhat depressing (it is taking over very strongly).

But Andy recognised and pointed out this fungus which lives off a dead larva or pupa of a butterfly or moth under the ground.
Scarlet Caterpillarclub or Cordyceps militaris

Andy had recently spotted this plant which is not often seen in these parts at all. So I went to Talgarth to photograph it. We don't even see the common Fumitory species very often in our botanising trips...
White Ramping-fumitory, Mwg-y-ddaear gwyn or Fumaria capreolata

I will finish with some pictures of the experts at work:

A wet meadow near Pont Faen

I started this a few days back but didn't finish. Nothing very special - a hot day in a wet meadow!

With Ragged Robin
Ragged-Robin, Carpiog y gors or Silene flos-cuculi
Fool's-water-cress, Dyfrforonen swp-flodeuog or Apium nodiflorum
(which I hadn't pohotographed flowers of in the wild before)

Abundant Corn Mint with no sign of the more usual (for us) Water-mint.
Corn Mint, Mintys yr âr or Mentha arvensis

And another Gall. This may be Geocrypta galli or Dasineura hygrophila but we didn't look inside to see the larvae so can't be sure.
Fen Bedstraw, Briwydd y fign or Galium uliginosum (with gall)

A few patches of:
Great Burnet, Bwrned mawr or Sanguisorba officinalis

And earlier in the day we encountered this strking fungus in the gloom of a pine woodland.
Yellow Stagshorn or Calocera viscosa (I think)

Mainly Geology

My only outing last week was actually one with Hay U3A Geology Group. But we were at Craig y Cilau so there was plenty of botany to see and I even made a few records.

One such record was for this:
Autumn Gentian, Crwynllys yr hydref or Gentianella amarella

Just where we stopped to look at a this geological feature way below us:
Eroded glacial till at Craig y Cilau

The gentian would certainly be expected there - on the tramway in limestone rich grassland below the cliffs - but hasn't actually been officially recorded recently so it was useful to confirm its presence.

Senior Reserve manager, Jon, told me that it "is actually fairly widespread on the limestone but rarely (easily) visible if there are a lot of sheep about - for obvious reasons.  It appears to be more common than was previously thought, largely due to a decrease in sheep numbers over the last few years."

It also occurs at this time of year at Allt Rhongyr BWT reserve and on Gilwern Hill - always on our Limestone band.

We also saw:
Dwarf Thistle, Ysgallen ddigoes or Cirsium acaule

and
Fairy Flax, Llin y tylwyth teg or Linum catharticum

And plenty more that I didn't photograph. This picture was taken a while back but from roughly where we saw the Autumn Gentian:

Revisiting the backup plan

One of the excursions for the recent AGM Meeting involved scaling Cribyn and Pen y Fan and, given the weather history of the Brecon Beacons, there needed to be a backup plan for this one. In the event the day was glorious and many interesting species were seen at around 800m altitude on the steep cliffs.

So yesterday the botany group went to see the backup: meadows within woodland on the banks of the Nant Sere lower down the valley - the Sere rises on Pen y Fan.

We spent a lot of the time in a clearing which obviously is often very wet indeed. Yesterday it was still very damp but the tussocks were more of an impediment to progress than the water.

The highlight was probably a good population of:
Meadow Thistle, Ysgallen y ddôl or Cirsium dissectum

What we first spotted was these distinctive seed heads but when we go to the area there were plenty of the flowers as well as shown above.

There were few places suitable for lunch but we found one.



Sneezewort, Ystrewlys or Achillea ptarmica

Thanks to Sue for most of the pictures - only the one with her in it and the flower head of Meadow Thistle are mine.

BSBI Welsh AGM part 2

A few more pictures have come in from the Field excursions in the mid-July BSBI get together in Brecon.

First Stanner Rocks


Where the Spiked Speedwell was magnificent. 
Spiked Speedwell, Rhwyddlwyn pigfain or Veronica spicata

And a real rarity - only found at Stanner in the UK
Perennial Knawel, Dinodd parhaol Maesyfed or Scleranthus perennis subsp. perennis

Cwm Cadlan - updated (thanks Stephen)

Andy Jones addressing the key features of Juncus x kernreichgeltii
 Lunch

Broad-leaved Cottongrass, Plu’r gweunydd llydanddail or Eriophorum latifolium (the less common one - habitat)
Where Marsh Helleborines were abundant
Marsh Helleborine, Caldrist y gors or Epipactis palustris

Next, the intrepid exploration of the cliffs below Cribyn and Pen y Fan
The way up

On the cliffs




Some of the special plants found up on the north slopes of the Fans
Spring Sandwort or Minuartia verna

Roseroot, Pren y ddannoedd or Sedum rosea

Sea Campion or Silene uniflora (a long way from the sea!)

And the recently named Hieracium attenboroughianum, Attenborough's Hawkweed being shown by it's discoverer, Tim Rich:



On the way down
Wilson's Filmy-fern, Rhedynach teneuwe Wilson or Hymenophyllum wilsonii

And the idyllic and remote Cwm Sere to explore on the way back.




Thanks go to all those who sent me pictures - Julian, Andy, Stephen, Emily and Polly
