Bogs and Dunes, early April 2022

 Near to Wadebridge is a bog and heath called Rosenannon Downs managed by Cornwall Wildlife Trust. I thought I would visit as I had never seen Bog Myrtle before and it should be in flower. It was only a short drive and as soon as I drove onto the heath, I saw hundreds of Bog Myrtle, flashing like gold specks in the afternoon sun.

As you can see, it is a small woody shrub with golden coloured "cones" that contain the pollen and stigmas.

Myrica gale

It was nice finding something easily for a change!

Here's a habitat photo. The grassy strip by the road is where the Dandelions were found mentioned later on.

 

I had a walk about to see what else might be flowering. In the damper places I found plenty of Lousewort in flower, a parasitic plant, common in boggy habitats.

 Pedicularis sylvatica

One of thousands of Lesser Centaury amongst a carpet of Opposite Leaved Golden Saxifrage.

Ficaria verna and Chrysosplenium oppositifolium

This young rush was coming into flower. I hadn't seen this before, but found it to be the Black Bog Rush, a common plant here. The young inflorescences really were quite dark, which gives the plant its name. The plant eventually forms a large tussock and the black fruits persist into the next season too.

Schoenus nigricans

A very common fern here is the Soft Shield Fern. The fronds have a thumb shaped basal leaf and they run paralell to the stem.

Polystichum setiferum

Along the road verge (see habitat photo for Bog Myrtle above) was a grassy strip, kept short with rabbit grazing. Dotted all over it were Dandelions, so I took a sample to key out at home. This one appears to be Taraxacum brittanicum though I will ask the BSBI Taraxacum referee to confirm this later.

Once home, I noticed a Fumitory growing on bare earth in my garden. The concolourous top petal (all the same colour) means this could only be Tall Ramping Fumitory, a nice find for a garden.

Fumaria bastardii

The next day, I took a late afternoon walk on fixed dunes near Rock. This is a calcareous site, so the flora is completely different to most areas here.

Not much is showing yet, but in the sand dunes were carpets of Rue-leaved Saxifrage, a tiny, sticky plant that turns red with age. If you look at the photo below, notice the moss growing around it. This plant is barely larger than the moss!

Saxifraga tridactylites

There were hundreds of tiny specks of blue in the dunes. These were the flowers of the minute Early Forget-me-not. If you find a flower 2mm across, that's a large one.

Myosotis ramosissima

I then came acrosss a rather attrctive Euphorbia that I hadn't ever seen before. I guessed that it might be Portland Spurge and I later confirmed that it was. The stems were a deep red and it grew on the sand and in cracks in the rocks too.

Euphorbia portlandica

My last photo was of Cornsalad, rather small in this harsh environment. Seeds are need to identify them to species level and it's too early yet for them.

Valerianella

 So ended my trip this day. The flora is awakening and soon I won't be able to keep up with what comes into flower. I can't wait!

March and Spring Wildflowers - Cornwall

 It was still quite cold, though we had a period of dry weather with associated high pressure. This was a welcome relief from the endless rain of previous weeks, but brought with it cold Easterly and Northerly winds. Thus, Spring was still delayed.

 

I recorded a monad around Little Petherick, a small village between Wadebridge and Padstow and found my first ever Tall Ramping Fumitory. I found it again since, in my back garden, which is a new build with bare dirt and no plantings. Fumitories tend to all look similar, so lots of photos and measurements are normally needed to identify it. In this case though, this is the only species with larger flowers (over 11mm) with its top petal being all the same colour. For brevity, I only include this one photo, but in the field, I take many of all parts of the flowers and leaves.

Fumaria bastardii var. bastardii

Some of the views were pretty good too, though for most of the walk, you couldn't get near the creek's edge due to trees or fences. I was surprised here to find masses of Wild Madder (Rubia peregrina) which is very rare in Kent, but seems ever so common here. I should catch it in flower in a couple of months time.

The only sure 100% way to tell Polypodiums apart, is to microscopically examine the spore carrying aparatus in the sporangia.

this wasn't possible for me until Lidl happened to sell a cheap microscope which I bought and used straight away on these Polypodies. I could even attach my phone and take a photo, excellent!

I was pleased to say that the morphology of each plant matched the determination given by the microscope. This is Polypodium interjectum or Intermediate Polypody. The photo doesn't show all the rings that you need to count to determine the species, but it was my first attempt at one!

There are drawings for each species of Polypody in Stace 4, page 41, have a look.

No doubt I will be using the microscope on pollen and seeds from assorted other species too.

The first Wild Garlic were flowering, or Ramsons as some know them as. They smell strongly of garlic so can't easily be mistaken for anything else. I included this photo as it shows the flowers and the leaves which are bright green, shiny and glossy. They usually grow in shaded places by roadsides, but they are happy with anywhere permanently damp. On the ground they usually grow in dense mats of hundreds of plants.

Allium ursinum

The first Wood Anemones were out too now, these in a lay-by off the A39 north east of Wadebridge. There are no huge carpets of them like in the East of England, but they look great nonetheless. Again, I include a photo to show the leaves too. These sometimes persist into late Summer allowing one to record them after the flowers have long gone.

Cornwall has miles of slate or stone walls covered in earth, often hundreds of years old. As such, you can get underneath many plants that grow on them for photographs, without getting muddy knees, like this one!

Anemone nemorosa

In a boggy area off the road were these mysterious leaves. After some research I determined they belonged to the Greater Cuckooflower, a plant I have never heard of until now. I will return to see some flowers I hope later on in Spring.

Cardamine raphanifolia

More fantastic scenery, this time across the River Allen, the whole length of which is an SSSI for plants and insects. This is actually a footbridge and a ford across the river. It drains into the River Camel at Sladesbridge just upstream of Wadebridge.

By the ford, I found a plant I recognised as Water Purslane. Unfortunately, it was in flower bud with none yet open, however, the flowers are small and unexciting anyway... This plant sometimes grows in mud or places that flood in Winter and dry out in Spring.

Lythrum portula

By the river, I also found a mystery plant that I had not seen before. One patch by the road and another half a kilometre upstream well away from any habitation and clearly not planted. My Twitter botanist friends identified it for me as Lesser Knotweed. It was first found in the area over 10 years before 2 km upstream. So it has obviously spread downstream from there over the past decade or so all by itself. At present though, I wouldn't say it was smothering out other plants. Two patches in a large distance isn't really of concern.

Koenigia campanulata

Below: close up showing the purple veining and edging to the leaves.

My final plant stood out as very obvious as it was bright blue. It was a Primrose, much like the type you buy in a supermarket at 50p each. I took some photos as it was obviously not planted and was amongst native plants on old fly tipped soil. I laterdiscovered the find was a first for VC1 and 2 (West and East Cornwall) for this particular cultivated hybrid. I can't say such garden escapes particularly excite me, but it's still nice to get a 1st occasionally.

Primula x pruhoniciana

So ended March. April began, still with a cold weather pattern overall, but as I write this on the 5th April, it is currently mild, so Spring will come in full soon. It's also Dandelion time, so some of those will no doubt feature in my next blog. As I now live in Cornwall and not Kent, I am sure I will encounter completely different Dandelion species too.

Hidden Gems at St Kew Highway, Cornwall March 2022

I just picked this area to visit at random, mostly as it has easy parking. The areas I looked at were rural road verges, an arable field and an allotment. However, the visit did throw up some interesting surprises. As I came to a stop in a lay-by, the first Cornish Blackthorns were coming into flower.

Prunus spinosa

Cornwall is full of non native plants that have done very well in the milder climate of the South West. One of the most successfull is Three-cornered Leek. It seems to be on most roadsides in the area.

Allium triquetrum

This is a Shrub Ragwort. The original bushes were likely planted along the A39 as amenity planting, but they have since naturalised and spread (like Ragworts do). Of interest is that there is a specific variety of Broomrape that parasitises this species, so I may go back and have a look in June to see if these plants have any.

Brachyglottis x jubar

Here is the ubiquitous Garden Archangel adorning a roadverge. Lots in flower now, but this was the first one I saw in flower this year. Cornwall mostly lacks the native form of Yellow Archangel (which has plain leaves) now.

Lamiastrum galeobdolon subspecies argentatum

I do lots of plant recording but I don't wait until plants are in flower to identify them. By sheer repetition, one gets to know what they are, plus I always pay attention to the leaves when they are in flower to match them up at a later date, such as now.

This is Betony, it has very distinctive leaves and can't be mistaken for other species once you know what it is. This is a "desirable" plant in Cornwall and is called an axiophyte as a result.

Betonica officinalis

The road verges are coming alive with wildflowers now. Here's the first Common Vetch I've found flowering, though I've seen the leaves straggling through grasses a while now.

Vicia sativa subspecies segetalis

Assorted Speedwells are also in bloom. These include Common Field, Grey Field, Germander, Ivy-leaved and this (relatively) large flowered Slender Speedwell. This last one is found in lawns, parks and road verges and winds through the grasses. Note the reniform leaves (kidney shaped), it's the only Speedwell that has them.

Veronica filiformis

As the Spring grasses grow, thus other plants have to compete and grow taller. This is the usually diminuitive Dovesfoot Cranesbill, now ascending to the dizzy heights of about 15cm tall!

Geranium molle

Another Spring ephemeral that likes unimproved grassland is the Field-wood Rush, found here on a verge of the A39.

Luzulu campestris

It's coming up to the best time for many Violets too. Below is a white bearded form of Sweet Violet followed by a Common Dog Violet.

Viola odorata var. dumetorum

Viola riviniana

This one is the Ivy-leaved Speedwell. There are two subspecies, one has blue pollen as below, the other hasn't (subsp. leucorum). There are other minor differences too. 

Veronica hederifolia subspecies hederifolia

 

Here is the first wild orchid I've seen in Cornwall. Too early for flowers, but a welcome sight nonetheless. It's the Early Purple Orchid. The little white flower is a Barren Strawberry growing through the orchid leaves.

Orchis mascula

Tucked away within Brambles and Cleavers was this pink flowered bulb. Clearly a garden escape but none were nearby, so I suspect its origin was from old fly tipped material. It's clearly survived and flowered.

Scilla forbesii "Pink Giant"

Here's a habitat photo.

 Beautiful, aren't they.

 

I then came to an allotment, usually good for arable plants as most allotment holders don't use herbicides to any degree. Whilst there, I found this very tame Pheasant that followed me around waiting to get fed (it didn't).

Sure enough, I soon found arable plants such as this White Ramping Fumitory. These start out with white flowers, but change to pink after pollination. I've left some notes on the photo which are key points to identifying fumitories. I have another photo of white flowers hanging down (rather than up) from the same plant as suggested in those notes. Seeds are needed to get to sub species level here though, but none were yet present.

Fumaria capreolata

For some reason, an allotment holder grew the garden version of Wood Forget-me-not on his plot. As one would expect, this escaped to other parts of the allotment and beyond.

Myosotis sylvatica

There were several other plants of interest, such as Field Madder, Pineappleweed and so on, but the last plant I photographed here was an escaped Borage, well off the plots onto nearby land.

Borago officinalis

 

*** Star Find ***

Now here's a weird story. A fellow botanist on Twitter was asked by the County Recorder to go and look for a variety of Primrose that hadn't been seen in the county since 1922 which was near his home in Bodmin.  He described it to me out of interest and I did some research on it too. I thought I would keep an eye out for it (given how many thousands of Primroses adorn Cornwall's roads), but I never for one moment thought I'd find it the very next day!

This is a form of wild Primrose which has an elongated central pedicel (flower stalk) from which numerous individual pedicels arise and fall laxly around it. The flowers are simple Primrose ones and to finally rule a cowslip hybrid out of the reckoning, it had long wavy hairs up the pedicels too. Although not clear in the photo, the petals were yellow, not white. Reflection has caused this effect in the photo.

Again, one photo has notes of interest, including an extract from an early 20th Century botanist who described the variety. This isn't described in Stace volume 4 but is in Sell and Murray.

I took detailed photographs including using a microscope of the hairs on the pedicels and the County Recorder agreed with the identification. An excellent find. This site had at least three "umbels" arising from rosettes.

Primula vulgaris forma caulescens

Last recorded in Cornwall 100 years ago and only ever seen 17 times since the first sighting in 1848.

There are lots of things to find, discover and re-discover wherever you are, so get out and about and see what you can find now Spring has properly arrived.

Take care
