Here’s some recent items, from a very busy summer!

August 9:

A recording day in SW coastal Cumbria, with Cumbria Biodiversity Data Centre, organised by Gary Hedges. We looked at Low Church Moss, Beckermet, NY045057, and at the cluster of kettle-hole mires between Braystones and Nethertown, of which Silver Tarn (NX998068) is the largest.

The mires were all remarkably distinct in appearance and plant-communities, presumably an aspect of their stages of development, varying from quaking-bogs surrounding areas of open water, and very wet marshes and fens, to quite firm valley-mires with no standing water. A great variety of plants, with a few of them below. Perhaps most striking were colonies of Royal Fern Osmunda regalis at two sites. “Colonies” was the right name, since there were encouraging numbers of smaller plants, and even patches of tiny ‘new’ plants.

A Flora of Cumbria Recording Group meeting in the Blea Tarn area (the Blea Tarn between Great and Little Langdale): a small amount of a bladderwort in one of the ditches at the outflow fitted Utricularia stygia, seemingly the most common (or least rare) of the intermedia aggregate in the county.

The amazing “quadrifid hairs” on the inside surface of the (2mm long) traps have to be exposed and must be examined to get a firm ID. I find it best to get a photo and work from that to estimate the divergence, etc., of the hairs’ arms.

The seepages in Blea Moss below Blea Tarn had some small colonies of Bog Orchid, Hammarbya paludosa. These seepages are more open than many where this plant grows, so making the tiny shoots rather more conspicuous. The flowering plants were at their peak, and the tiny bulbil-fringed leaves of the vegetative plants were remarkable, once spotted. [JR]

July 31:

A walk along the boardwalk over Bowness Common (starting from the RSPB carpark at North Plain Farm. Most surprised to see a good colony of about twelve large plants of Fine-leaved Water-dropwort, Oenanthe aquatica, by one of the ponds just before the hill up to Rogersceugh Farm.

This is only the second extant county record, the other being in a ditch along the Roman Wall west of Irthington in the north of the county. A surprisingly rare plant in the county.

The Gypsywort, Lycopus europaeus, was in fine form and abundant by one of the ponds at North Plain itself.  [JR]

July 14:

Phill and I met with RSPB manager at Haweswater Reserve, Lee Schofield, and we looked at a section of the Reserve along Gatescarth Beck which now has an exclosure fence, and already is illustrating how rapidly such herb-rich areas of the Lakeland uplands (260-330 metres a.s.l.) can ‘recover’ when the vegetation is allowed to ‘go its own way’ for a spell.

Lee has kindly provided more details of this project:
The RSPB, in partnership with United Utilities, plan to develop an area at Mardale Head to show off the diversity of Lake District flora. They have identified an area, already reasonably botanically rich, that will be fenced to exclude livestock and deer to encourage greater diversity. 
Nearby Harter Fell is well known as a crag with a good mountain flora, but the many wonderful and colourful species that grow here are out of sight from the general public. Many plants that we consider ‘mountain plants’ only grow on crags and ledges since these are the only places that they can escape grazing pressure. Given the opportunity, these species will happily grow in more easily accessible areas. 
There are various places around the UK where livestock exclosures have been put up and a diverse upland sward can now be seen, Ben Lawers in Scotland being one of the most well known. There are no equivalents in the Lake District, so it is hoped that over time, this area at Haweswater will develop into a place where visitors can come to appreciate the diverse and beautiful suite of species that were once so much more widespread.

Besides three saxifrage species (Mossy; Starry; Yellow) and many other herbs, most striking was the presence of about thirty plants of Alchemilla wichurae, Rock Lady’s-mantle, down the stream-banks.
This is the only place so far in Lakeland where I have ever seen this species ‘come down off the cliffs’. Of course, it was already here in the pre-exclosure flora, but overlooked until now amongst the small, grazed, Alchemilla glabra plants, when it has had a chance to shine!
There was also a superb patch of the lichen Peltigera leucophlebia – one of the three species of bright green dog-lichen with a green-alga Coccomyxa as its main algal complement. (Most Peltigeras have the blue-green Nostoc, and so look some shade of brown, grey or purple. These green ones still have Nostoc, but only in the little ‘warts’ – cephalodia – on the surface.) [JR]

At the end of the day we dropped down to look at the large areas of silt in the draw-down zone at the head of the reservoir. All plants were very tiny, perhaps partly through exposure to the elements (altitude 245 metres a.s.l.) here and partly the frequent grazing of Canada, Barnacle, and Grey-lag Geese!

The main colonists were in sheets: flowering Water Purslane, Lythrum portula, and two water-starworts, Callitriche. Some of the latter was the usual Common Water-starwort, C. stagnalis, with spoon-shaped leaves, but the other one, narrower-leaved, much commoner, and indeed in tens of thousands, was puzzling, until Phill washed the silt off some plants and found that the ripe fruits, previously buried, were black – an unusual character in Callitriche, but characteristic of Narrow-fruited Water-starwort, Callitriche palustris, a species new to Cumbria.

31st July update: The BSBI referee for the genus, Richard Lansdown, has confirmed our identification, but adds that the various other records for England (currently about 20 in the BSBI Distribution Database, in 12 vice-counties) remain unconfirmed, and hence this Haweswater colony would seem to be the first confirmed English record! [JR]

Other plants: some gravel beds had lots of tiny plants of Corn Spurrey, Spergula arvensis – a rapidly declining plant in UK as an arable weed. However, A Flora of Cumbria does mention its occurrence on the draw-down zones of reservoirs.

Further up in the grassy fringes were a few plants of Heath Dog-violet, Viola canina, evidently not recorded previously in this catchment, and probably a colonist onto gravel at some earlier stage when water-levels were higher. (It is on lakeside gravel in the Lake District, e.g. by Ullswater and especially frequent along some stretches of the eastern shore of Derwent Water.) [JR]

September 3:

Nigel Gilligan made a good find at the southern end of Millom Docks – as Nigel says, “an arid and hostile environment for most plants”: Vervain, Verbena officinalis[photos by NG]

Long spreading flowering shoots arise in opposite pairs

This appears to have very few recent records for the county, and it is good news that it is still around.

The distinctive ‘five-lobed but two-lipped’ flowers of Verbena 

July 29:

Lois Harbron writes: “I was at Augill Pasture Cumbria Wildlife Trust reserve on 21 July, counting the second flush of Frog Orchids, Dactylorhiza [Coeloglossum] viridis, and spotted an obvious hybrid of some sort from a little distance. On closer observation, I was sure it was a Frog/Common Spotted hybrid [× Dactyloglossum mixtum*], given its appearance and neighbours. Luckily I was due to meet Alan Gendle nearby. He was happy to confirm my sighting, and sent photos to Richard Bateman. I was lucky not only to find it, but in that the plant was at its peak, a lovely specimen.” I am delighted to add her fine picture here.

The form of the flowers is reminiscent of Frog Orchid, except the lip is three-lobed (two-lobed in Frog) and the spur is longer. The colour of course matches that of the Spotted-orchid parent, with loop-markings on the lip somewhat ‘faded’ in this example.

Is this hybrid new to the Cumbrian vice-counties? There’s no mention in A Flora of Cumbria, and the BSBI Distribution Database currently has no record. The only other record for the whole of northern England that I’ve spotted is in the new Hybrid Flora which seems to be that mentioned in the Distribution Database from Co. Durham by Heslop-Harrison in 1964, but with no more recent record given there. The Hybrid Flora reports the hybrid in a total of 28 hectads in the British Isles, with most in south-central England and the Outer Hebrides.

(*On the question of the abandonment of the much-loved generic name Coeloglossum for Frog Orchid, and its transfer to Dactylorhiza, I note that the Hybrid Flora just published says “the present evidence for the separation or amalgamation [of these two genera] is somewhat equivocal”, echoing Stace’s comments (New Flora, 3rd ed., 2010), “Coeloglossum is morphologically very distinct, and molecular evidence suggesting its amalgamation with Dactylorhiza is not yet unequivocal”. No prizes for guessing which side of the fence I prefer on this vexatious issue. As far as the correct nomenclature for the hybrid goes, the epithet mixtum appears to apply whether the hybrid resides in Dactylorhiza or in × Dactyloglossum.) [JR]

July 19:

Much recording going on around the county!

One of my favourite plants, Campanula glomerata, Clustered Bellflower, is showing well at a few sites in the county.

In the open and sunny sites on thin limestone soils east of Shap, even at 340 metres altitude, a few shoots are already in flower, but more are still in early bud. Typical heights of shoots are about 30 centimetres.

Meanwhile, by the River Eden, at only 60 metres altitude, a plant in tall riverside vegetation is still managing to survive, but its stems are a metre tall to compete with surrounding perennials, and it is not quite in flower as yet. [JR]

July 12:

Before a Carlisle Natural History Society outing at Clints Quarry CWT Reserve, we called in at Maryport Marina. The Yarrow Broomrape ~ Orobanche pupurea was in astonishing abundance over a large area: has anyone had time to do a thorough count in recent years?

Yarrow Broomrape ~ Orobanche purpurea [JR]
Yarrow Broomrape ~ Orobanche purpurea, Maryport [JR]
It was first found here in 1983 (A Flora of Cumbria). Its existence here is a puzzle, with the nearest sites being in Lincolnshire and South Wales. However it arrived, it is clearly very well-suited to the situation (artificial slag and ballast heaps) and the local climate.

The other great draw is the super-abundance of Pyramidal Orchid ~ Anacamptis pyramidalis. [JR]

June 29:

Carex aquatilis Borrans Mo Richards Jun 15
Water Sedge ~ Carex aquatilis, Borrans Marsh [Mo Richards]
One of the specialities of Borrans Marsh, at the head of Windermere: Carex aquatilis, Water Sedge.

Small forms, not quite so well defined as the one pictured, grow in patches across the marsh itself, but perhaps the best forms occur in small quantity in the strip of marginal vegetation by the river to the west, growing with Typha angustifolia, Lesser Bulrush (*), and other tall emergents.

A member of the Carex nigra (Common Sedge) group, it has just two stigmas (thus distinct from a great many other sedges, which have three, although only useful before the stigmas shrivel, and eventually are shed).

It is closest to Carex nigra itself, in being patch-forming rather than strongly tufted, and in having the stomata on the upper or inner surfaces of the leaf, making that surface matt and grey, whilst the lower or outer surface has few stomata and so is shiny and green.

It is easy to tell from C. nigra by its usually much greater vigour, smooth edges to the more rounded stems below the inflorescence, very long female spikelets narrowing below (well shown here), and especially by the very conspicuous, leaf-like, channelled, wide, and long bracts: the lowest bract (arrowed in the picture) is the best-developed, and often greatly overtops the whole inflorescence. (The two do hybridise, however, and some populations may show introgression.)

The finest UK sites are probably those in the Spey Marshes, where the plant may be dominant, and over 1.5 metres tall. In a strong wind, the long bracts sweep, sway and hiss!

The other patch-forming sedge in this group, Carex acuta, Slender Tufted-seddge, also has longer bracts, although not so splendidly developed as here, but that has stomata on the lower surface only, and a sharply-angled stem.

Water Sedge occurs in several of the swamps and marshes in the Lake District, by the River Irthing in far north-east Cumbria (and on a few other riversides), and there is a recently-found series of patches of a stunted form by the Pennine Way on the north side of Great Dun Fell at 800 metres a.s.l., in which the stem is actually much shorter than the inflorescence. This form grows taller when cultivated at low altitudes, so may be stunted simply by the climate at height (Linda Robinson, pers. comm.).

(* This writer greatly prefers ‘Reedmace’ for Typha, and ‘Bulrush’ for Schoenoplectus, for which Stace has ‘Club-rush’.) [JR]

June 19:

Bugloss
Bugloss ~ Achusa (Lycopsis) arvensis [JR]
A Flora of Cumbria Recording Group meeting to the Aspatria area in West Cumbria. On this sandy ground (with a huge sand-quarry across the road), in an uncropped corner of a field at Aikshaw, north of Aspatria, there was a cluster of delightful arable weeds. Most conspicuous were masses of Bugloss ~ Achusa (Lycopsis) arvensis. There were many plants of Corn Spurrey ~ Spergula arvensis and Field Pansy ~Viola arvensis, and a couple of plants of the local Field Woundwort ~ Stachys arvensis: all those “… arvensises” (“of the fields”).

A meeting of the Flora of Cumbria Recording Group to the Warcop area, in the upper Eden valley, on a warm and sunny day.

Lists were collected in three tetrads. Few highlights, but the very local water-crowfoot Ranunculus pencillatus subspecies pseudofluitans was admired at Warcop Bridge.

The eastern end of Sandford Mire was penetrated by one group. Some very depauperate Lesser Tussock-sedge ~ Carex diandra was located with other sedges. [JR]

June 6:

Mike Porter brought the participants of his ever-popular ‘Sedge Day’ to Dubwath Silver Meadows (as below) on the afternoon of 6th June, particularly to see the Water Sedge – although the wind was so fierce and cold that the various wattle-and-daub huts on the site were welcome retreats!

The morning was spent at the newly-announced Cumbria Wildlife trust reserve at Eycott Hill, west of Penrith, where twenty species of sedge were recorded, despite the cold wind. There is vast amounts of Bog-sedge ~ Carex limosa at this site, and many patches of Few-flowered Sedge ~ Carex pauciflora. [JR]

 June 4:

Alchemilla wichurae Kentmere smaller
Rock Lady’s-mantle ~ Alchemilla wichurae, Kentmere [JR]
A patch of the Rock Lady’s-mantle ~ Alchemilla wichurae was spotted under a boulder by the stream dropping steeply down the fellside just north of Rainsborrow Crag, Kentmere. It appears to be the first record of this local montane Alchemilla in the Kentmere valley: the nearest known sites are north across the watershed into the Mardale valley, on Harter, Blea Water, and Small Water Crags. This was a particularly clear form, with the rounded leaf, closed sinus (ie. the basal lobes overlap), wide, rounded lobes, and many fine, curved teeth.  [JR]

May 30:

Carlisle Natural History Society outing to Dubwath Silver Meadows (by the Pheasant Inn, at the north end of Bassenthwaite).

The site is being managed to enhance its wildlife value and to protect the catchment’s water supply. New boardwalks and paths allow access to the various features of swamp, willow carr, open marsh, and hay-meadow.

Although the site has only a few species of sedges, we were surprised to see the Water Sedge ~ Carex aquatilis in several areas, including scattered all over the ‘Snipe Bog’ – the marsh occupying much of the northern half of the site. This local sedge of northern and western Britain is known locally by Bassenthwaite Water, and elsewhere, but may not have been recorded previously at the site. Another frequent sedge was Bladder Sedge ~ Carex vesicaria. [JR]

  1. A call for help with running a bioblitz event at Haig pit Whitehaven on Sat 2 July. The first one, we have flower rich grassland, coastal heath and scrub habitats and are keen to get as many species recorded as possible to have an idea of how our conservation management is working and if we need to alter our approach to accommodate any of our wild residents. Any help appreciated.

    Chris

  2. How common is Thorn Apple, Datura stramonium in the county? It has popped up in our local allotments (Kirkoswald). I also have what appears to be an Apple of Peru, Nicandra physalodes. At least, it is a physalis-like plant with blue flowers.

    1. Very scattered and irregular, Lois. A Flora of Cumbria has eleven records during the Survey period, as you will see. I’m not certain how many records are accruing since that publication. Would be very interesting to know if it is increasing.
      Do make sure these valuable records get recorded – contact details are elsewhere on this site.
