Botanical Finds for mid June 2022, Cornwall - Part 1

 Here are some of the amazing plants I found at this time in North Cornwall. Most trips out are on the spur of the moment for a few hours here and there rather than planned trips. As such, I'll highlight a few species from each trip to show you the best finds.

June is the time for orchids and there will be lots of them featured later. However, below is the very first Southern Marsh Orchid that I've seen in Cornwall and it was less than a mile from my house in a damp field corner. Of course, since then, I've seen thousands. They are very common here.

Dactylorhiza praetermissa

 

 A visit to a local Common which also had several boggy areas revealed the first ever Oblong leaved Sundews that I'd ever seen too. It's much rarer than the common Round Leaved Sundew.

Drosera intermedia 

 

 Of course, most bogs have Common Cotton Grass too. It was a windy day and I managed to capture some of the grass (which is actually in seed) splayed out horizontal to the ground by using a very fast shutter speed.

Eriophorum angustifolium 

 

The first Bog Asphodel of the Summer had come into flower right next to a Heath Spotted Orchid, delightful.

Narthecium ossifragum and Dactylorhiza maculata

 I then found a rare orchid hybrid hiding behind some Western Gorse. It was the hybrid between Heath Spotted and Heath Fragrant Orchids. I'd never seen this hybrid species before and it was also a new record for the area.

X Dactylodenia evansii

It also had a lovely scent taking after its Heath Fragrant parent.

 Below is a small part of Rosennnon Down, where the above plants were found. There are several such areas round mid Cornwall and each has its own flora. I look forward to exploring them in due course.

 My next venue couldn't be more different than above, it was a brownfield site in Bodmin next to Home Bargains. It was on an industrial estate and was a cleared area of concrete full of plants having been abandoned and left undeveloped for a few years.

Very soon I found another new species, this time an alien species from New Zealand. At the time I did not know what it was, but I have since discovered it to be New Zealand Willowherb. The leaves are very distinctive and I've since found it in several urban areas.

Here is it's quite small flower.

Epilobium brunnescens

I then found two cudweeds, a speciality of dry brown field sites. The first was Jersey Cudweed, apparently spreading through England quite quickly now. The easiest way to identify it is that it is covered in silvery grey hairs so looks shiny.

The flowers weren't quite open yet, but they're minute anyway.

Laphangium luteoalbum

 And Common Cudweed, such a cute wildflower. It's actually in the Daisy Family, so is related to Dandelions and Daisies, Thistles and Knapweeds.

Filago germanica

 The final plant of note there was Heath Speedwell, there were loads of plants, all in flower, turning the ground blue!

Veronica officinalis

 My next trip out was a proper field trip with the Cornwall Botanical Group. Below, we went to Harbour Cove and Tregirls Dunes on the Camel Estuary, both of which were stuffed with wildflowers.

Here's some of the group being shown Sharp Rush. It's so sharp and rigid, that the protruding spine at the top would take out an eye if you were careless enough to bend down near one.

 Juncus acutus

 Most were familiar with False Oat Grass as it grows almost everywhere. What I didn't know however, was that there was a subspecies that grew corms underground. However, you have to pull it up to verify it, unless you can get down low and pull away some soil to see the corm. 

Arrhenatherum elatius subsp bulbosum

 The Sharp Rush was a new species for me and so was this Sedge below. It had a super long bract going up and away from the fruiting body to distinguish it. No wonder it's called Long-bracted Sedge. 

Carex extensa

 Eyebrights are notoriously difficult to determine to species level, but these were relatively easy. Western Eyebright is the only Eyebright that has symmetrical flowers facing out in four directions. I took this above the flower photo to show it.

Euphrasia tetraquetra

 Some Evening Primroses were in flower but looked odd. I took numerous macro photos of the relevant parts and the county recorder took a sample. We both later concluded the plant was a hybrid between  Oenothera glazioviana (Large-flowered Evening-primrose) and Oenothera biennis (Common Evening-primrose). It was called Intermediate Evening Primrose, not very imaginative!

Oenothera x fallax 

 Of course, when looking at plants, you see some of the insects that feed on them. This is a Nettle Weevil which is irridescent blue

 Phyllobius agg

 There were of course many other interesting plants we saw that day including the hybrid between Ladys and Hedge Bedstraws. Organised field trips are always worth going on if you can attend, do so. I had to leave a bit early and missed several plants of interest so I will re-visit the area to find them soon.

 

After this, I returned to another common/bog, this time Retire Common, just west of Bodmin.There were some beautiful Early Marsh Orchids there too.

Dactylorhiza incarnata subsp. pulchella

 

 A Golden Ringed Dragonfly waiting for the sun to come back!

Cordulegaster boltonii

 

 

Bog Pimpernels were now flowering. Since I took these, there are now carpets of them in some places.

Lysimachia tenella

A nice find was a few Marsh Speedwells, a rare species that lives in or very close to water.

Veronica scutellata

Another new Sedge, this one with floppy green bracts like droughted grass leaves. It's Common Yellow Sedge. It grew close to the ground rather than upright.

Carex demissa

There's so many more plants but the blog is becoming overlong, so you'll have to wait for part 2, coming soon to see them.

Take care

Botanical Finds for the first week of June 2022, Cornwall.

June marks the the beginning of Summer, so plants take off big time from now on.  Spring was very dry overall with many annual  species suffering and those that did make it, had a very short flowering period. Overall it has been cooler than usual too, thus some species have been flowering later.

The following are the plants of note that I found in the first nine days of June. I think they are interesting and I hope you do too.

Common Spotted Orchids are quite rare in Cornwall. They don't like acid soils much and are replaced by Heath Spotted in most of the county. However, there is an area of clifftop near Tintagel on the north coast where only Common Spotted Orchids are found and they are a special type too.

Depending on what taxonomy you follow, these are either a seperate sub-species or a named variant. There were hundreds here and all looked similar with completely pink petals. Personally, I think they are simply a variant, caused by hybridising with Southern Marsh Orchids many years ago and then introgressing back with Common Spotted Orchids again. Some appear intermediate with Southern Marsh but all lack the "grandeur" of the hybrid, 'D. x grandis'. They are actually very diminuitive orchids.

Dactylorhiza fuchsii subsp. hebredensis 

(as recorded on BSBI & ERICA databases)

or possibly

Dactylorhiza fuchsii var. cornubiensis 

(Aphotoflora.com and Britain's Orchids: A Field Guide to the Orchids of Great Britain and Ireland

Book by Mike Waller and Sean Cole (which I highly recommend).

Whatever view is taken, they are an attractive small orchid and definitely a 'type' unique to this area.

Along the cliff edges past the orchids were stands of Hare'sfoot Clover, a fluffy little plant with tiny whie clover flowers hidden within.

Trifolium arvense

Some people mistake the wildflower below as an orchid and from a distance it can look like one. It's Hoary Plantain, the only "showy" plantain we have. In the Cornwall Flora book recently published, it's shown as probably extinct in the county. As such, I've been visiting places where it was recorded upto 100 years ago, usually churchyards, but had not found it anywhere.

I then botanised a local industrial area and found two flowering plants by the side of the road! I imagine they were seed contaminants of a seed mix used to beautify the verges after the roads were built for this estate some years ago. However, it's a great find.

Plantago media

Sea Fern Grass is very common here and probably is around much of the UK coastline, however, it's quite smll and often goes unnoticed. It's a stiff, fleshy plant in keeping with living in a salty environment. It's now expanding its range inland due to Winter road salting too.

Catapodium marinum

Here is another plant adapted to living in a salty environment. Sea Spleenwort, a fern that grows in tidal splash zones and cliffs exposed to salt. I'd never seen these before.

Asplenium maritimum

 

Another coastal plant is Brookweed, however this one has to have its feet wet or damp and is found in such areas by the sea. These were just coming into flower at Trevose Head in a disused quarry with a damp area within it.

Samolus valerandii

This violet below was a tiny speck of purple in the clifftop turf. I thought it was a small Common Dog Violet, but a closer look showed it to be a Marsh Violet. An odd location for it, perhaps with normal rainfall, this part of the clifftop is usually wet?

Viola palustris

At Trevone Beach cliffs, I found another species new to me, Garden Parsley. There was a lot of it growing on the Cornish walls here. It looks way too green to be Cow Parsley and has solid stems and yellowish flowers. Of course, the leaves smell and taste of parsley too. Please don't taste any umbellifer uness you know what plant it is, as some can kill you or make you very ill (and quickly) as they are very poisonous.

Petroselinum crispum

Sometimes I don't feel like driving anywhere and just walk my local area. There's always new things to see locally too. This is Water Bent, a common naturalised alien grass that I see most everywhere now. When fresh it's a very bright green, hence 'viridis' in its name.

Polypogon viridis

 

Garden escapes can be found in the most extreme places. In this street drain is a flowering Trailing Bellflower!

Campanula poscharskyana  

There are quite a few grass verges around where I live and they are stuffed full of herbs. I'll have to return later to find out for sure what the plant below is. It had flowers with both 4 and 5 petals on and could either be a hybrid Cinquefoil or Trailing Tormentil (itself a stable hybrid named as a species now). You can only tell for sure what it is if it sets seed (anglica), or flowers wither without any seed being set (hybrid).

Growing out of walls everywhere in Cornwall is Navelwort, also known as Wall Pennywort. The plants are usually a shade a green, perhaps with some red colouring here and there. So it was very unusual to find this amazing example below of an all red form. It's deserving of a varietal status really, so I've invented  a var. name below!

Umbilicus rupestris var. rubra

 This is the usual green form. They are very slow growing, unsurprising given that they may not have access to many nutrients.

While the family walked a local beach, I explored the cliffs around it. This is Tall Ramping Fumitory, with flowers larger than 11mm, jagged sepals and usually a pink (not black) top petal. I think they are absent from Kent, so I'd not seen them before moving here.

Fumaria bastardii var. bastardii

I like finding Fumitories and I soon came across another, a much larger species, along a road verge. This species is the second largest in the UK and is called White Ramping Fumitory. The sepals are huge and the flowers tend to hang downwards. They can turn pink on pollination and in one variety they turn crimson, so look for fresh flowers to determine them easily rather than just their colour on first glance.

Fumaria capreolata subsp. babingtonii

With Cornwalls' mild climate, you never quite know what garden plant you will come cross living in the wild quite happily. Being so close to the sea, this Arum Lily in a wet ditch is unlikely to see any severe (or even moderate) frost, so may survive many years.

Zantedeschia aethiopica

Hoary Stock is a clifftop plant I used to see in Kent on the chalk. It isn't native in Cornwall, being introduced or an escape from cultivation (as is likely here), but it was doing fine on this acidic cliff near Polzeath recently.

Matthiola incana

This Soft Brome seemed very small, much smaller than usual, even if it was growing on an exposed cliff edge. When I posted it online, it was suggested that this was in fact a special dwarf coastal type of Soft Brome that is fairly rare. These plant were only about 2" tall. We'll see what the county recorder thinks, but it looks good for it.

Bromus hordeaceus subsp. ferronii

That about sums up the first nine days of June. Lots to see and lots more to come. I hope you liked the plants, take care.
