Grassington (VC64)

Grassington is not somewhere I have ventured for a few years, and with the priorities for the New Atlas it was not on the hit list of hectads to visit as it is already adequately re-recorded. But my mind has been on Potentilla lately and this is a key location for the 'Yorkshire Dales' problem. But that is a post in its own right, so more on that later. There is more than enough at this botanical hotpsot to fill a post, so a few highlights below.

My route took me first down to Linton and its falls (Potentilla wild goose chase), then along the river to Ghaistrill's Strid, into Lower Grass Wood, Grass Wood proper, back across the fields towards Grassington and up to Bastow Wood, before back to the village. A good route, with each location having its own special interest and enough to remind me that I need to get into this part of the Dales more often.

Starting at Linton Falls the sheer riverside cliffs had a small population of a distinctive hawkweed, and not only could I identify it (that's four now out of the 90 recorded from VC64, baby steps) but I knew I was right as there was a record in the database from an expert. This stunner, distinctive by hawkweed standards, was Wood Hawkweed (Hieracium silvaticoides). Later to be seen again on rocks by the river in Lower Grass Wood. The photo is a plant in situ growing out of vertical rock, what a tough plant.


There was a second hawkweed here, not in flower yet. I had a fair idea of what it should be and it is not to be collected under an circumstances, I suspect herbaria are already full of it.  So admired at a distance and as far as is known this is its only surviving population, and it occurs no where else in the world. I only saw two plants! A precarious existence, water on one side, sheep and tourists on the other. This is Linton Falls Hawkweed (Hieracium lintonense).


The River Wharfe here has some exceptionally good stands of Opposite-leaved Pondweed (Groenlandia densa)

In Grass Wood I was really pleased to stumble over some Herb-Paris (Paris quadrifolia) in full bloom. Flowering plants have eluded me for so long, normally it is well into berry and past its best. Sure I could have twitched it somewhere it if I wanted, but I am quite happy to wait until something wants to reveal itself to me. A memory based on a sense of time and place has much more meaning.



Finally, at the base of a drystone wall on the way back to Grassington was an abundance of Brittle Bladder-fern (Cystopteris fragilis).

Stackhouse Detour (VC64)

I took advantage of the favourable weather forecast on Thursday and headed out to Settle. I'm not sure why I had not made it there sooner given it couldn't be easier by train, but my trips to the Dales have been all too infrequent as I focus efforts elsewhere for the New Atlas. Halfway round my planned circuit to Giggleswick Scar and back, I came to the little hamlet of Stackhouse and thought it worth a brief detour. Its fair to say the "spidey senses" were tingling and I've learnt not to ignore those! The gut-feeling didn't disappoint particularly when I found a little track that went round the back of the village between some high, old limestone walls.

First up was a fine stand of Hairy Bindweed (Calystegia pulchra), a bit of a thug but a very fine thug. I last saw this species 10 years or so ago in Wales, so a re-encounter was long overdue. This is a rare plant in the county and the historic records have a very low level of detail associated with them, so it was good to find a new location and record it accurately.


Next up was an even scarcer species and a new one for me - Lamb's-tail (Chiastophyllum oppositifolium). Just a shame I had missed it in bloom, as this huge colony must be an impressive sight when covered in yellow flowers. Previously this species has only been reported from Bowland, so this is a marked range extension.


Here's what I had missed earlier in the season ...

My luck was still in when, just round the corner, were two large plants of Elecampane (Inula helenium). This is another rare plant and predominantly found in the east of the county.


Elsewhere, I almost discounted the Yellow-flowered Strawberry (Potentilla indica) for the Wild Strawberry (Fragaria vesca) which is common on the scars above Stackhouse. Luckily there was a single flower and then I clocked the distinctive fruit. This is only the second record for the VC, and the first record lacks a detailed grid reference.



Final mention must be made of the uncommon white-flowered form of Ivy-leaved Toadflax (Cymbalaria muralis subsp. muralis) that was adorning some of the walls.This goes by the cultivar name of 'Pallidior'.
