New Year Plant Hunt

Happy New Year Shropshire botanists and wildflower enthusiasts!

We are not doing an organised group New Year Plant Hunt but you can still take part, following your local COVID guidelines, of course. Shropshire is never top of the leader board for plants in bloom at this time of the year, even in towns as we still get a recognisable winter. But that doesn't matter, all records are of interest to the BSBI in reviewing the flowering trends in our flora.

The New Year Plant Hunt is easy to do and a good excuse for a nice long walk.

Check the BSBI website for full details: https://bsbi.org/new-year-plant-hunt-how-to-take-part

Basically it involves 3 hrs (per hunt - you can do several) of recording plants in bloom, until Mon. 4th Jan. Have fun, stay safe, take photos!

Least Water-lily, Nuphar pumila - conservation by Royal Botanic Gardens, Kew

Today is the 20th Anniversary of the establishment of the Millenium Seedbank, located in Sussex.  It is the world’s largest underground seed bank & conservation resource for global wild plant species.  For more info on the project check out the MSB webpage.

It seems a fitting day to provide an update of the project which started in 2016 to review the genetic status, ecology, and condition of Least Water-lily Nuphar pumila, at Cole Mere, Shropshire, the only population in England. 

Nuphar pumila Least Water-lily, by Dan Wrench

The partnership included SBS, Natural England, the Royal Botanic Gardens (RBG) UK Native Seed Hub, Conservation Genetics and nursery teams, Richard Lansdown (Chair IUCN Freshwater Plant Specialist Group), site managers Shropshire Council, and also volunteers from the Shropshire Wildlife Trust and Colemere Sailing Club.  The latter provided boat transport for a local Dive Club who were enlisted to count the number of petioles emerging from the rhizomes, not their usual dive remit but it was received enthusiastically after a little training.

The vulnerability of the species at Cole Mere was of concern and the project aimed to:

1. Provide a summary of the ecology of Nuphar pumila, management and monitoring recommendations

2. Carry out seed viability tests, and propagate seeds and rhizomes for ex-situ conservation and public display at Kew

3. Carry out DNA analysis to detect hybridisation with Yellow Water-lily Nuphar lutea, also present at Cole Mere.

4. Devise an in-situ conservation management plan.


Seed pods were carefully collected, making sure they were the right species.  The seed pod has a lobed stigmatic disk in contrast to Yellow Water-lily Nuphar lutea which is also present at Cole Mere.

The Nuphar pumila seeds were found to be 95% viable, which was great news.  BUT successful germination depended on very specific conditions, especially light levels and only 10 live seedlings  were obtained from 100’s of seed, which was very labour intensive.  Even worse news, all of these seedlings subsequently died.  The seedlings were watered with tap water and Kew had problems with algal growth.



So hopes are now pinned on the rhizomes which were collected during the same operation.  Each year many free floating rhizomes are found on the lake edges, possible uprooted by waterfowl, likely mute swans feeding on the submerged leaves.  Some of the less bruised ones were collected and taken for propogation, but the majority were too battered and died:

However, recent news from Kew is that from the remaining rhizomes with healthy shoots they have managed to divide these and have several healthy plants in the collection which they hope to divide again.  The best conditions appear to be a loam based compost and outside in ambient conditions rather than indoors in a controlled environment.  The mixed success of the propogation shows how important it is to ensure in-situ conservation measures at Cole Mere are as favourable as possible for the species and to continue to monitor the populations.

Zooming into the AGM and "What's in a Name"

We are feeling just a little pleased with ourselves that we held an enjoyable and successful virtual AGM at the weekend.  We swiftly dealt with the Committee business, electing Mags Cousins to Chair and Martin Godfrey to join the Committee; heard the annual report from outgoing chair John Handley, given by Sue Dancey; and the financial report also from Sue, which was all good in a nutshell.

John thanked committee members for their work, especially Hilary Wallace and Gordon Leel for the hardwork of producing the Newsletter, there is a snippet below from a previous edition.  Hilary is stepping down after the autumn edition, and Andrew Perry has agreed to become Editor.  We're always looking for more material and articles so if you have anything that you would like to submit, please email shropbotsoc@gmail.com



After the AGM business was dealt with, we handed over to Mark Duffell of Arvensis Ecology, for an informative and entertaining talk with slides:

"What's in a Name"  A short romp through the science of naming the natural world. Through stories and quirky discoveries learn how plants (and animals) have been named and what their names mean, not all in Latin either!

It is remarkable how some old names given to plants have stood the test of time, whilst others were remarkably descriptive but rather long winded and have changed beyond recognition.   He tested us with this one, do you know this plant? Ignore the chat box, that won't help as Cowslips in cow pats were answers related to the previous slide - yes, he kept us on our toes:


Answer below:


Another quirky fact, a revelation to some in the audience was the penchant for naming plants after wives, friends and foes, and the use of anagrams.  Mitella (Bishop's caps) and Tellima (Fringecups), two different genera, anagrams of each other due to similarities in appearance:


One from the audience is what is behind the name Polypogon monspeliensis, Annual Beard-grass?


It turns out it used to be in the genus Alopecurus and monspeliensis is derived from Montpellier in France where it was discovered.  There were lots of other interesting stories behind plant names, far too many to mention here.  

Huge thanks to Mark for providing the evenings entertainment.  It was lovely to see everyone's little faces again, or just icons for those that were camera shy or simply didn't have enough band width!  Hopefully we will meet in person again before too long, but Zoom-ing together at least provided a chance to get together with fellow botanists and delve into botanical facts.  Thank you to everyone who joined us, including non member guests.

Virtual AGM Sat. 26th Sept. 7pm

Members will have heard already we're going virtual for the AGM, next Sat. 26th 7pm, a first for the society. Most of us have had a fair bit of practice with video meetings this year so we're sure to have an enjoyable evening, especially since our very own Mark Duffell will be giving a talk:

"What's in a name - a short romp through the science of naming the natural world."  Through stories and quirky discoveries learn how plants (and animals) have been named and what their names mean, not all in Latin either!

If you are curious about the meaning of a particular plant's scientific name, for instance what does ‘galeobdolon’ mean and how does it relate to Yellow Archangel, then now is your chance to ask.  Mark will attempt to discover the meaning (etymology) behind your favourite plants name (native or non-native, hardy or not) so send your question to him in advance on: mark@arvensisecology.co.uk

At the end of the talk there will be a question and answer session when Mark will provide the answers.  If you don't send your question in advance then we will have to work it out together on the night!.

The Zoom meeting is open to non members so message us for a link, or email: shropbotsoc@gmail.com.    

You can probably guess this one Common Fleabane, Pulicaria dysenterica:


We're really looking forward to getting together again, may be even seeing you (virtually), but if you're feeling camera shy you don't have to have your own video on!

More on Sedges... by John Handley

Just like everyone reading this post, being in lockdown, I’ve had to adjust my botanising over the recent months. In the first instance I was trying to sneak a look at plants whilst undertaking my hour of exercise – at one point trying to be inconspicuous whilst admiring the Convallaria majalis, Lily-of-the-Valley, that has naturalised within Bridgnorth Cemetery. 

Recently I’ve been able to enjoy botanising locally which has provided a respite for my family as much as me. One of the areas I’ve been exploring is Stanmore Country Park, an area that has developed from scrub after the RAF Bridgnorth Training Camp was closed in 1963. The vegetation would initially have been dominated by Salix caprea, Goat Willow, and Betula pendula, Silver Birch, and this process is still enclosing the few areas of open grassland that remain. It is an area that is commonly used by dog-walkers, including my family and I. It didn’t occur to me that the secondary woodland and grassland held much interest but encouraged by Ed Andrews, the Country Parks and Heritage Sites Manager, I decided to have a closer look. 

I was pleasantly surprised to discover a diversity of species and semi-natural habitats that are providing a great deal of benefit for local wildlife as well as a much valued space for local residents. Along with over twenty eight individual Epipactis purpurata, Violet Helleborine (is it a good year for them?) I also recorded Carex divulsa subsp. divulsa, Grey Sedge. This is regarded as a rare plant within Shropshire (Lockton & Whild, 2005). The Rare Plants of Shropshire remarks that "although this is a common species in the south of England and Ireland, Shropshire is just on the edge of its range, and it seems to occur here only as a casual.  Of the two subspecies, the only one to have been found in Shropshire is ssp. divulsa. It has been recorded on roadsides, ditch-banks, and along paths in gardens."

The other sedge that I recorded, occurring quite frequently in the better grassland on the acid, sandy soils that occur around Bridgnorth, was Carex muricata subsp. pairae, Small-fruited Prickly-sedge.  This is not to be confused with C. muricata subsp. muricata, Large-fruited Prickly-sedge, which is believed to be one of the rarest sedges in Britain, but occurs in Shropshire, discovered in 1999 by Dr Sarah Whild on limestone scree at Jones’s Rough (SJ2424).  

Grey Sedge and Small-fruited Prickly-sedge are in the subgenus Vignea where the inflorescence is more compound, and the spikes are small in comparison with those of many species in subgenus Carex.  Members are characterised by having bisexual, sessile spikes, where the female flowers have two stigmas each. As you can see from the images the two species differ markedly by the interrupted inflorescence and diamond shape of the utricles, narrowed from above and below in Small-fruited Prickly-sedge. 

Carex muricata subsp. pairae, Small-fruited Prickly-sedge


Exploring in the neighbouring monad, at a local reservoir with a boggy margin, I came across another couple of sedges.  Carex hirta, Hairy Sedge, is less discriminating than many sedges and often the first sedge to come to my attention because of its conspicuous hairiness.  In amongst the verdant vegetation of the water’s edge the swollen, golden utricles were conspicuous, although the grazing water-fowl appeared to prefer Carex disticha, Brown Sedge, which was spreading through extensive rhizomes. A single tuft of Carex pseudocyperus, Cyperus Sedge, with its pendant piano-wire peduncles and bristly inflorescence was great to see, although common in the centre and north of the county where there are more water bodies, it isn’t so common in the south of Shropshire.

Searching within the surrounding grassland I recorded Carex pilulifera, Pill Sedge, a tufted sedge that can tolerate the drier soils in the south east of the county.  Here it was lacking the close-set male flowers which I think gives it a distinctive shape.
