Expected and Unexpected finds

The week started with the unexpected: on a walk to stretch our legs around the block in Hay last Sunday I spotted this right next to the pavement as we passed the Medical Packaging factory near the Meadows.
Autumn Lady's-tresses, Troellig yr hydref or Spiranthes spiralis

This is rarely seen in the county but I suspect may be under-recorded. Now is the time to watch out for it in short turf. But obviously the mower and sheep are its mortal enemies - there could well be places (like this in Hay) where it grows but rarely gets to present a spike for long. The insignificant rosette of basal leaves has withered by the time the flowering spike emerges.

So for my eagle-eyed helpers here is a better picture of one from Uphill near Weston-super-Mare to show what to look out for:

Then after the volunteers picnic at Allt Rhongyr (BWT reserve) we did a walk around the reserve and spotted the significant number of white-variant Devil's Bit Scabious in amongst the swards of the normal blue variety:
Devil's-bit Scabious, Tamaid y cythraul or Succisa pratensis at Allt Rhongyr

Nearly back at the cars we were very pleased to find a second site for the reserve's signature plant:
Autumn Gentian, Crwynllys yr hydref or Gentianella amarella at Allt Rhongyr

But when two of us went to Brechfa Pool to answer the question put to me by a visitor a week earlier: "what is that growing out in the deeper water", I was humbled to find that it was actually just Soft Rush with some Marsh Bedstraw amongst it. Good to establish the answer but not the "interesting sedge" my less-than youthful eyesight had me hoping for. 
Soft-rush or Juncus effusus in wetter than normal conditions

We then did a four mile circular walk through the lanes and byways around Brechfa and the common above the pool, generating a good and varied list of records including this Broad-leaved Helleborine by a roadside:
Broad-leaved Helleborine, Y galdrist lydanddail or Epipactis helleborine

And I finally got the shot I wanted of Bittersweet:
Bittersweet, Elinog or Solanum dulcamara

Finally on Friday I joined a BSBI group very much with an expectation in mind for what we should find as we were looking for the Bog Orchid near Pont ar Elan. Populations fluctuate from year to year (and are never very high).

So it was a relief after many flushes had been examined in detail high and low by a large number of BSBI botanists to finally hear the call from Gillian Foulkes that one was found. It turned out that this - with an associated non-flowering plant and one smaller spike were all we were going to see of this in the whole day.

This species does grow in Brecon (and Paul Green confirmed one site last year) but I have yet to see it in my county. It will be tricky to spot if plants are the size of the smaller (more typical ?) one we found at Elan:

Not a lot to report except...

Keith Noble has spotted a Small Blue butterfly (Cupido minimus) near Brecon:
"A worn female Small Blue, which, going by the Millennium Atlas, is the first Powys record."

This, I read, is our smallest resident butterfly with a wing span that can be a little as 16mm. Unfortunately this specimen may be a long way from it's sole larval food-plant, Kidney Vetch (Anthyllis vulneraria), which is only known to we botany recorders at a few sites on the limestone at the south of our county. It may be that we have a population of this, often coastal, plant nearer though - perhaps on a road verge site where seeding has been done and limestone used. However what I know about butterflies wouldn't fill a postage stamp in large print so let's hope this isn't the last sighting.

Heaven for a Small Blue

We postponed the planned expedition to the Black Mountain this week due to poor weather and hope to make it there next week so I decided to walk the bridle way from Brecon to Y Gaer yesterday and got a lot of records - none spectacular. But sometimes a picture opportunity just presents itself in front of your camera as happened here while I was eating my lunch near Cradoc on the way back.
Hogweed or Efwr, Heracleum sphondylium

The camera was out of my bag to record this new viewpoint of the Beacons for me:

I'm also on the lookout on days like that for updates to common species where I feel I haven't yet got a really good picture so I tried to get one of plentiful Bittersweet here:
Bittersweet ir Elinog, Solanum dulcamara
Still not the picture I am seeking !
another in the same vein:
Meadowsweet or Erwain, Filipendula ulmaria
at least I have anthers covered now...

Brambles, Roads and Car Parks

I spent three days in North Wales on a Brambles Course last weekend. They are now slightly less of a mystery than they were but I'm only starting on a difficult road if I am going to get to recognise easily even the more common of about 500 species !

Rubus ulmifolius - the only sexually active species and quite common
(one I ought to get familiar with)

I have many more pictures from this course on floralimages.uk but won't burden this blog with any more!

On Wednesday the group (well two of us) went along to help Steph record a long Road Verge Nature Reserve near Henrhyd Falls. While waiting at our rendezvous in Brecon at the BBNP Car Park (police Car park also) I noticed a good stand of the newly named Knapweed I featured last week. So anyone who wants to examine this species can go along and see it easily there...

Slender Knapweed, Centaurea debeauxii at the at the BBNP Car Park in Brecon

At the roadside near Henrhyd we found many interesting things including:

Common Hemp-nettle or Y benboeth, Galeopsis tetrahit
Zigzag Clover or Meillionen igam-ogam, Trifolium medium
Beech Fern or Rhedynen gorniog, Phegopteris connectilis
