To Addingham and Back Again (VC64)

Time for a bit of a catch up on local news. Last week I took a trip over to Ilkley as I had always fancied a walk along the river towards Bolton Abbey, but had never quite made it. Spring was definitely springing in Wharfedale, but not as advanced as on my local patch. So I enjoyed a second final hurrah from the daffodils, while also being able to enjoy some of the species just starting to come into there own.

It was nice to see the thriving colony of Fairy Foxglove (Erinus alpinus) on Old Bridge, Ilkley. Far too early for flowers though.

Not a rare plant, but I forget how prolific Few-flowered Garlic (Allium paradoxum var. paradoxum) is along the Wharfe. All those bulbs where there should be flowers.


A surprise find on a tree stump well away from gardens was Trailing Bellflower (Campanula poscharskyana), but this is not my first find of this species on an isolated river bank.


On the river bank at Addingham, and likely of planted origin, was Star Jasmine (Trachelospermum jasminoides).


Moving up hill away from the river towards Langbar, I was surprised to find a Chameleon ... i.e. Sweet Spurge (Euphobia dulcis 'Chameleon'). The hedgerow along Langbar Lane also had the hybrid hawthorn Crataegus x subsphaerica (to be seen again later in the hedge bounding Ilkley golf course).


Another nice find on Langbar Lane was a particularly robust lush clump of Alternate-leaved Golden-saxifrage (Chrysosplenium alternifolium).


A rubbish photo but this odd Daffodil (Narcissus 'Pipit') lit up a shady beck bank at Nesfield. I'm not even going to try linking this to a named Daffodil species or hybrid! Google it for a better image.


Back towards Ilkley were Garden Solomon's-seal (Polygonatum x hybridum) and this striking, and very early into bloom this year, Broom (Cytisus scoparius subsp. scoparius f. andreanus).

Alexanders in Giggleswick (VC64)

Alexanders (Smyrnium olusatrum) is a rare plant in VC64 and indeed Yorkshire in general. It is a more familiar plant further south, particularly in the southeast and southwest of England. See the BSBI Distribution Database for its current distribution.

Mike Canaway adds a new dot to its distribution, having found it in the Dales at Giggleswick. He forwards the following photographs.

Goldilocks

Passing through Methley churchyard (VC63) yesterday a blaze of gold caught my eye. Most of it was attributable to Lesser Celandine (Ficaria verna), an impressive swathe nonetheless. But on closer inspection another plant came into focus and I realised there was also a fairly large stand of Goldilocks (Ranunculus auricomus) mixed in.


This seems to be a fairly uncommon plant locally, with this being a new hectad. This was a particularly fine form with large fully formed flowers, unlikely the form in VC31 where there are normally petals missing from newly opened flowers. This species is one of the last apomictic species groups in the British flora to be investigated critically, and at present it is very poorly known with no available reference to help untangle the diversity.

Viola riviniana subsp. minor

Common Dog-violet (Viola riviniana) is a familiar plant of woodland and hedge banks. It is normally of lanky appearance, with elongated flowering shoots. I found an extensive colony of this species today in North Lincolnshire, in open acid grassland and in a guise I was not anticipating. This was not helped by the botanical parts of my brain which are still groggy from a winter of under-use.

This dwarf form was well known to Victorian botanists but has fallen by the wayside in recent years, and goes by the name of subspecies minor (or sometimes var. minor). Whether it would stand close scrunity in cultivation trials is another matter, but based on the field evidence it merits re-evaluation and recording. Those like me who still value their copy of Keble-Martin's Concise British Flora will find it illustrated and some descriptive notes on its identification.

Flowering Currants

Nothing beats, as far as I am concerned, the early spring exuberance of Flowering Currant (Ribes sanguineum). My childhood memories are not just of the colour and the scent, but also the buzz of countless bumblebees attracted to this bountiful nectar source. In Yorkshire the latter seems to be reduced, presumably because the cooler climate means that the flowers are too early to coincide with the first brood of worker bees.

It is not a native plant but is commonly naturalised in VC64. In VC31 it is rare and usually of planted origin. Everyone knows the standard red flowered form, but there are other cultivars with flowers of different shades. In West Yorkshire (VC63 and 64), a pale pink form is commonly encountered and given its predominance around Woodlesford clearly breeds true. The name 'Pallescens' seems to cover this plant.

Shoal of Minnows

See the daffodils springing into bloom reminded me of some photographs sent by Bruce Brown a few weeks back. He has known a stand of vegetative non-native daffodils at Grass Wood (VC64) for a number of years, but was finally able to grow an offset to flowering in 2016.

Setting aside (the desire to rant about!) the need of certain sectors of society to introduce non-native bulbs into native wild habitats, this is certainly an interesting find. It is clearly a member of the tazetta group and appears to match the cultivar 'Minnow', a popular cultivar registered in the early 1960's.


The origins of 'Minnow' are obscure but the Daffodil Register suggests that it is a backcross to N. tazetta from an earlier cross of cultivars that may have involved N. poeticus in the parentage. Perhaps involving parents similar to 'Canaliculatus' (probably a form of tazetta subsp. tazetta) and 'Poetaz' (tazetta x ?poeticus), between which it seems intermediate. If true it has a similar but more complex origin to Primrose-peerless (Narcissus x medioluteus), but this name as currently used has a rather narrow concept. Whatever the origin it is a charming little daffodil.

February Highlights (VC31)

Brian Laney has sent the first records for 2017, following a recent botanising session at Peterborough Services of all places. However, as I know from my own experience, it is such places that often turn up the goods. Brian definitely did.

Brian's best find was Knotted Clover (Trifolium striatum), spotting it in its vegetative state. He sent this photo.


He also found several rosettes of Bee Orchid (Ophrys apifera), offering the promise of flowers to come.

Other good finds for this part of the county were Spotted Medick (Medicago arabica) and Knotted Hedge-parsley (Torilis nodosa).
