British & Irish Botany: issue 3.3 published

Snake's-head fritillary
Image: P. Stroh
We've just pressed 'publish' on the latest issue of British & Irish Botany, BSBI's online, Open Access scientific journal. 

This issue features ten papers, starting with a report by BSBI Head of Science Kevin Walker on the lovely Snake's-head Fritillary Fritillaria meleagris. Kevin's blogpost about this iconic plant, as part of our Wildflower of the Month series during lockdown, proved very popular and in this new paper he analyses its occurrence in different habitats and discusses its claim to native status. 

Next up we have a paper by Michael Braithwaite about the discovery of the local flora as reflected in BSBI vice-county datasets. Michael uses Berwickshire, where he was County Recorder for many years, as a case-study and his account makes fascinating reading for all botanical recorders in the run-up to publication in 2022 of our next plant distribution Atlas

Mayweeds on Orkney

Also in this issue we have a report on Sea Mayweed, Scentless Mayweed and their puzzling  intermediates in Orkney; and Mick Crawley considers the dramatic recent increase in abundance of Rat's-tail Fescue Vulpia myuros as a weed of winter wheat-fields - he reports on a long-term experiment at Silwood Park, Bucks. to discover what extent this increase is due to no-till cultivation, or to herbicide-resistance, or to autumn cultivation coupled with warmer winter weather.  

Authors of BSBI Handbooks have been busy too: Mark Lynes describes three new species of Lady's-mantle Alchemilla from northern Britain, ahead of publication, probably next year, of his long-awaited Alchemilla Handbook; and three new species of Dandelion are described by John Richards in the run-up to publication of his new Field Handbook to British and Irish Dandelions, due out next month. BSBI members should watch out for the special members-only discount offers on both these books.

Hepste Hawkweed

Over to B&IB Editor-in-Chief Ian Denholm to tell us about the four remaining papers in this issue:

"Within the family Polygonaceae, Redshank Persicaria maculosa and Pale Persicaria P. lapathifolia are both common in Britain but subject to confusion through over-reliance on flower colour as a distinguishing feature. Michael Wilcox reviews contrasting taxonomic treatments and provides guidelines for rationalising considerable variation within the Pale Persicaria ‘complex’.

"Tim Rich continues his survey of the status of Britain’s Hawkweeds (genus Hieracium) with a report on Hepste Hawkweed H. apheles - an extremely rare endemic restricted to five plants in a single locality in the Brecon Beacons. This is one of several endemic taxa with a threat status of ‘critically endangered’ according to IUCN criteria, safeguarded to some extent by the deposition of seed in the Millennium Seed Bank.

"Finally, Clive Stace and Duilio Iamonico resolve issues of species typification within the genera Vulpia and Atriplex, respectively".

So, another jam-packed issue with something for everyone. British & Irish Botany is free to read (and free for authors to publish in) and there's no log in required - just head over here to start enjoying the latest issue and then why not browse our archive? We are now accepting submissions for the fourth and final issue of this third volume, due out in December - why not get in touch if you are thinking of contributing?

Plant monitoring on Mull: September report from BSBI President Lynne Farrell

NPMS plot on Mull

Last month BSBI President Lynne Farrell was on South Walney, escaping the heat and looking at coastal plants. 

So where is she this month? On another island? Yep! 

Over to Lynne:

"I’ve been busy both in the field and in the office over the past month. In my vice-county, Mid Ebudes, I have re-recorded my plots on Mull for the National Plant Monitoring Scheme (NPMS). 

I set my plots up in 2016, shortly after the Scheme started

Tunbridge Filmy-fern

The NPMS is one of the major projects to which many BSBI members have been contributing. If you would like to get involved, click here to find out if there is a square near you.

I have also been checking a few of the rarer species localities including the Tunbridge filmy-fern Hymenophyllum tunbrigense. Wilson's filmy-fern H. wilsonii is much more common but there are only a few sites for H. tunbrigense, although both have a similar distribution mainly along the western coasts of Britain and Ireland. 

Tunbridge filmy-fern - yes, the spelling is different in the Latin and common names - was first found in Britain in Tunbridge, Kent, hence the name.

The WILDGuides book Britain’s Ferns by James Merryweather came in useful as the photographs are excellent, so encouraging people wishing to learn more about these attractive species. The only drawback is that the pages are not waterproof.

However, the publication has been awarded the Presidents’ Award this year - this is the annual prize awarded by the Presidents of the BSBI and the Wild Flower Society

You can see more about the previous winners here.

James wanted us to see the beauty of this group of plants and to encourage us all to enjoy and easily identify them. Other books provide more detailed text, which complement this volume. 

Back in the office I have been writing my annual Message from the President for the new BSBI Annual Review, which will be mailed out to members inside the September issue of BSBI News and will be on the website soon after.

I've also been attending a meeting of the Board of Trustees and other Committee meetings, and planning for the BSBI Annual Exhibition Meeting and AGM in November. 

So, a busy month!"

Plant-hunting on Ben Nevis with BSBI Scottish Officer and Team RBGE

View south from the summit of Ben Nevis
Image: J. McIntosh
Jim McIntosh, BSBI Scottish Officer, regularly walks the hills and climbs mountains in pursuit of interesting plant records, but he was recently invited to join a particularly interesting expedition. 

Over to Jim to tell us more: 

"19th August 2021 was the 250th anniversary of the first recorded ascent of Ben Nevis – by botanist James Robertson, who had been commissioned by John Hope, the King’s Botanist and Superintendent of the Botanic Garden, to explore the native plants of Scotland.

"Robertson’s account of the day given in A Naturalist in the Highlands- James Robertson – his life and travels in Scotland 1767-1771 is very brief, and he doesn’t even record what species he saw except that ‘the plants here are similar to those on Ben Awin and Carngarm..’ (Ben Avon & Cairngorm - for which he provides detailed lists in earlier pages). 

"He continues tantalisingly ‘only here, at the west side near the foot I found the M…’ but gives no indication what species ‘M’ is though it must be particularly notable for him not to name it in full! He describes the ‘the third part of the hill towards the top is entirely naked, resembling a heap of stones thrown together confusedly’.

"Fittingly a visit to the summit of Ben Nevis was organised by the Royal Botanic Garden Edinburgh (RBGE) to mark the occasion, and the group included today’s Regius Keeper, Simon Milne, and Director of Science, Prof Peter Hollingsworth, RBGE bryologists and lichenologists, representatives from land-managers the John Muir Trust and Jahama Estates; NatureScot, the Sanger Institute and me!   

Jim & #TeamRBGE colleague pressing specimens

"The idea was to collect specimens for the exciting new Darwin Tree of Life project which aims to sequence the entire genomes of all (70,000) animals, plants & fungi in Britain & Ireland. And we also collected specimens of Alpine Meadow-grass Poa alpina and Mountain Sorrel Oxyria digyna to lodge in the RBGE Herbarium to mark this special occasion. Click on the links to see BSBI distribution maps for those species. 

"We chose to ascend Ben Nevis via the challenging Càrn Mòr Dearg and its famous arête. And, of course, I couldn’t help recording (for Atlas 2040 of course!) as I went along. 

Jim (on left) & colleagues on 
Càrn Mòr Dearg arête

"Also, because Càrn Mòr Dearg itself is one of our top ten highest mountains, at 1220 m, I made a full list of all flowering plant species within 10 m vertical of its summit, while everyone else enjoyed a leisurely lunch as the mist and drizzle gradually cleared. I logged 20 species in total, including many arctic-alpines of more acid substrates as befits a granite ridge.  

"As we scrambled along the ridge, we noticed occasional patches of Moss Campion Silene acaulis, more commonly seen on base rich soils and crags but somehow also happy here. But a highlight was finding Sibbaldia  Sibbaldia procumbens on the ridge and pretty commonly on late snow line areas on the lower plateau of Ben Nevis. 

Simon Milne & Sibbaldia

"This is an important species for RBGE, which was co-founded by Robert Sibbald in 1670 and now has Sibbaldia as its emblem. The Regius Keeper duly knelt and paid homage to the diminutive plant.

"After group photos at the perfectly still summit, and short interviews to camera by Simon and Peter, we began the descent, collecting more bryophytes and looking for some of the most exciting flowering plant species. 

"No point in recording here after the comprehensive and thorough North Face Survey involving botanists and climbing guides in 2014-2016, but nice to chance upon Brook Saxifrage Saxifraga rivularis (image below) beside a cairn at the top of one of the gullies.

"Even more exciting was renewing acquaintance with Tufted Saxifrage S. cespitosa nearby – it's one of our rarest and most important arctic-alpines, on Schedule 8 of the Wildlife & Countryside Act (W&CA) 1981 and listed as Endangered on the GB Red List.

[Ed.: Check out the BSBI Code of Conduct for the full lists of plants on Schedules 8&9 of the W&CA and read more about the GB Red List here.] 

"Late in the evening as we descended the main path the sun began to break through wispy clouds, low in the west. 

"We eventually returned to the carpark some 12 hours after starting off on the 20km, 1500m ascent expedition tired, hungry but very happy!"

Many thanks to Jim for this fascinating account - sounds like a great day! 

Being a botanist really can take you to the most amazing places. 

If Jim's account has left you hungry to read more about botanising on Scottish mountains, check out our 4-part 'Botanical Book at Bedtime' by Peter Llewellyn, all about his plant-hunting adventures in the Cairngorms - part one is here.

We'll leave you with an image taken by Jim of the view from the path on the descent - enjoy!

Call-out for Restharrows

Botanist Mike Wilcox has been looking at Restharrows Ononis spp. and now he has a request - over to Mike:

"Recently, plants seen of Ononis do not fit the description in Stace (2019) for O. repens (on right) and not fully for O. spinosa (below left) even if using Sell & Murrell where O. repens is treated within the subspecies of O. spinosa

"Whether these are hybrids or not is debatable. In relation to the two taxa and putative hybrids, I would be interested in material (fresh) to have a look at in detail, including some anatomical aspects as they are given as two different chromosome numbers in Stace (2019) and looking at aspects such as stomata it might help decide what the two taxa are and or putative hybrids.

"It may be a bit late to start doing this but I will pick it up next year and hopefully see more material from different areas.

"Meanwhile, if you have one or both (or putative hybrids) I would be interested to see some material for a preliminary look at these taxa. Email me at for details of where to send your specimens".

BSBI Training Grants: Supporting botanists in 2021: Part Two

View of Salisbury from Old Sarum Castle
Image: K. Mason
Following on from Mike's account of the 'Using a Flora' course, which he was able to undertake thanks to a BSBI Training grant, we now present Kevin's account of the course he attended in May:

"My journey in plant identification began when I studied a degree in Animal biology and conservation, and more recently my passion for wildflowers has been fed in my current role as a Wildlife Trainee with the Berkshire, Buckinghamshire and Oxfordshire Wildlife Trust. My position means I get to spend my days in amazing habitats from floodplain meadows to ancient woodlands.

The incredible diversity of wildflowers I see each day is both beautiful and daunting, and it seemed that as soon as I got to grips with identifying one species, countless others would spring up around me as the season went on. While I like to attempt identification by myself, I felt attending a course in wildflower ID would give me an edge. Thanks to a training grant from BSBI I was able to book myself onto a course.

The course I had chosen was the ‘Wildflower Identification and Survey - Neutral and Calcareous Grasslands’ course, run by the Species Recovery Trust. We met on a rather wet day at Old Sarum Castle on the edge of Salisbury, the cathedral barely visible through the steady rain. Despite the weather, spirits were high and I was really keen to get out into the grassland with the other attendees. 

Our tutor for the day, Dominic, started us off with some common but important species of grasslands and meadows. While I could already quite confidently identify Trifolium pratense and T. repens (Red and White clover), I learned that you can quickly get an idea of the nutrient levels of a grassland by how much White and Red clover is present – more White clover generally means higher nutrient levels. We soon found Lotus corniculatus (Common bird’s-foot trefoil), another common but important grassland flower, told apart from Lotus pedunculatus (Greater bird’s-foot trefoil) by the latter having a hollow stem.

Image: K. Mason
After we had gone over most of the flowers at Old Sarum Castle, we got back in our cars and made the short trip up the road to Figsbury ring, an Iron age hill fort managed by the National Trust. The entrance track was more suited to a tank than my little car but I eventually made it in one piece. We regrouped in the car park and had a quick look at the surrounding flora. 

The group had spotted a large white umbellifer and had misidentified it as Anthriscus sylvestris (Cow parsley), as had I. Dominic told us that cow parsley would mostly have gone over by the end of June, and that what we had found was actually Chaerophyllum temulum (Rough chervil), identified by the purple spotting on the stems. After a quick brief on the history of the site we walked on to see what we could find.

Immediately it was obvious that the flora was more diverse at Figsbury, which is a Site of Special Scientific Interest due to the quality of the chalk grassland present. My eyes were instantly drawn to the orchids – Anacamptis pyramidalis (Pyramidal), Dactylorhiza fuchsii (Common spotted) and Gymnadenia conopsea (Chalk fragrant). Moving on we saw my personal favourite, Hippocrepis comosa (Horseshoe vetch), with bright yellow pea-like flowers arranged in a horseshoe and 4-8 pairs of pinnate leaflets.

Unlike Maria (above), Kevin didn't see
Frog Orchid - let's hope he sees it soon!

The short sward of the chalk grassland was ideal for spotting small, low-growing wildflowers such as bright pink Thymus polytrichus (Wild thyme) whose leaves had a disappointingly weak scent, and the memorably named Squinancywort  Asperula cynanchica with attractive pale pink, 4 petaled flowers. Earlier on in the day Dominic had shown us how to make a “gun” with the flower head of Plantago lanceolata (Ribwort plantain), which is quite drab as flowers go, so when we saw Plantago media (Hoary plantain) I was impressed by how bright it was with its white flowers and purple filaments.

After a final unsuccessful search for Dactylorhiza viridis (Frog orchid) which are reportedly present at Figsbury Ring, Dominic decided that it would be sensible to finish early and get out of the rain. While a part of me was disappointed to finish the day early, I was also very relieved that I could finally get a little drier. Despite the rain I had a great day out and learned so much from Dominic, and I am already looking for the next plant ID course to attend!"

Thanks Kevin, we're delighted that you were able to enjoy the course!

Hotting up: August report from BSBI President Lynne Farrell

"The weather has certainly hotted up in the past month and some extreme temperatures have been felt all around Britain and Ireland. This might well have attracted people to aquatic habitats and coastal areas. Now, at the beginning of August, a weather front is sweeping in, bringing heavy rain and strong winds, battering down the plants in our gardens and in the wild. 

The last few inclement days have provided me with an excuse to watch the Olympics, and I discovered that seeing the events unfolding live in the early morning was infinitely preferable to watching the review in the evening, so my usual timetable has changed too, and will revert to normal soon.

The hot temperatures and bright sun actually made me retreat to shady areas when outside and the local lime trees, many of which are Small-leaved lime Tilia cordata in Cumbria, are laden with flowers, which the bees appreciate. After a dearth of honey last year, this will be a bumper season.

Pollinators such as hoverflies have been late emerging and now are flying strongly. The large Fritillary butterfly species have benefitted from the warmth and good numbers have been observed allaying concern that many were disappearing in some parts of Britain. Earlier species did not fare well. The butterflies woke up early too in the morning sun so counting and photographing them on my weekly transect walk was challenging. Luckily part of the walk is in the shade.

However, choosing an overcast day with tolerable temperatures, was definitely required for a visit to South Walney island nature reserve to enjoy coastal breezes and plants that love exposed areas. Viper’s Bugloss Echium vulgare catches everyone’s eye due to its abundance and striking colours. The rarer, and poisonous Henbane Hyocyamus niger,  (top right) is also attractive but only to look at. 

Sea Holly Eryngium maritimum is also a coastal species being found at the back of the dunes, often where they are just stabilising, whereas Yellow horned-poppy Glaucium flavum (on right) prefers the shingle banks. Wild pansy Viola tricolor ssp. curtisii (above left) which occurs both in dunes and further inland on heaths, quickly shrivels up in the heat. So I hope you have all survived this hot spell".
