Cornwall Botany - Early to Mid July 2024

 I don't know where the time goes. It seems like only a short time ago that the  Spring flowers were opening and now we are well into Summer. Having said that, the weather hasn't been very summery at all, with only a few sunny warm days, the rest being overcast or wet. However, that's not all bad news, as the plants like to be kept watered and last longer as a result. Here follows some of my early to mid July finds in Cornwall.


Below is a very misleading photo from a Cornwall Botany Group field trip to Northcott Mouth north of Bude. It's misleading as it rained incessantly for most of the trip and we cut it short, dripping and bedraggled. A strong onshore wind didn't help matters either. Yet, a mile away north or south, it was a sunny dry day! We got stuck under a conveyor belt of heavy showers, unfortunate, but sometimes that's how it is.


Due to the rain, I took very few photos as my camera and lens are not waterproof. I did take some photos of Common Dodder parasitising Common Gorse.

Cuscuta epithymum



I took a local evening walk around Egloshayle near Wadebridge and found some Wild Onion, or Crow Garlic growing on a cemetery wall.

Allium vineale


In a garden centre car park, growing through the tarmac, was an umbrella plant. This seems to pop up fairly often in the wild, mostly near habitation, but I did find some on arable field edges once.

Cyperus eragrostis


Sweet William naturalised near a churchyard which was its probable origin.

Dianthus barbaratus


The host of small Willowherb species aren't very exciting to look at and can be quite complicated to work out at times. The one below is Spear-leaved Willowherb, a speciality for the South West of England. It has a cross shaped stigma and unlike other species it has stalked lanceolate leaves. These often turn deep red as it ages and the flower is paler than the others. I had this verified by the BSBI Epilobium referee too.

Epilobium lanceolatum




Field Scabious is declining nationally and is a Cornwall axiophyte species (indicative of good habitat where it grows). As such, I always record them when I find them. These were on a Cornish hedge, so I could get under them for a different type of photo to the usual.

Knautia arvensis


The most common Mallows I see in Cornwall are Common, Musk and Tree Mallow, however, there are several other species to consider, including a few garden escaped tree mallow species. The flowers below were so vivid and the leaves quite large that I checked them out thoroughly in the books to see if they were something unusual. However, it turned out to be just Common Mallow, but what a lovely example of one.

Malva sylvestris


Lemon Balm was growing naturalised on a roadside bit of waste ground and as I knelt to photograph it, the smell was indeed very lemony!

Melissa officinalis



On the Cornish coastline and on the moors, English Stonecrop is the species you will find in numbers, however, once you get into urban areas or near gardens, White Stonecrop takes over. With its umbels of flowers it's a much showier Sedum than English Stonecrop, but it lacks pink in the flowers, so doesn't look as spectacular when there is a carpet of them.

Sedum album


One of the advantages of attending field trips with a botany group is that you can draw on the expertise of the others present. On this CBG trip to Cadson Bury Hill near Callington, we found Fragrant Agrimony, a plant I had looked for, but had never previously found.

It differs from the usual Agrimony in having almost smooth bases to their seedpods and the undersides of the leaves having numerous fragrant glandular hairs , so if you rub them, your fingers will have a pleasant smell left by those glands. Leaves are supposed to be bigger too, but I couldn't quite see that in this specimen.

Agrimonia procera



Autumn Hawkweed were about to flower at Cadson Bury Hill, several of them were popping up along the top of the hill.

Hieracium sabaudum


Cornwall Botany Group field trip to Cadson Bury Hill, admiring acidic grassland on the way down.


Cow-wheat was present in good numbers too.

Melampyrum pratense subsp pratense


Both species of Gorse were growing right on top of each other allowing for some comparison photos; they really do look quite different. Western Gorse is flowering now.

Gorse Comparison

 

Ulex gallii in flower


The last photo from that field trip was of Zig Zag Clover with its Red Clover like inflorescenses (but unlike Red Clover the whole being on a stalk above the sub tending leaves) and the narrower, hairy leaves of course.

Trifolium medium


On my way home from Callington, I stopped off to record a the road verges around the A38 near Liskeard. I was drawn to them as I drove by, by the fact that there were several bare areas on the verges and these aften have rare plants growing in them. I wasn't disappointed.

First nice plant wasn't on the bare ground, but nearby. It was Hairy Bindweed, which has a pink striped flower the same size as Large Bindweed, with sepals overlapping too. However, the flower stalk is usually winged and may also be hairy. This specimen was both winged and hairy, so an easy one.

Calystegia pulchra




On the bare aggregate of a slip road I found hundreds of Wall Bedstraw. They had all gone to seed and turned red now, but the growth form is quite unusual, being thin and weedy looking, with whorls of 6-7 leaves. Prickles on the leaves all point forward and the prickles on the stems downwards.

Galium parisience



On the same verge were several clumps of Imperforate St. John's-wort, this was only the second time I'd ever seen this species. As the name suggests, the leaves lack the transluscent spots and the petals are streaked with lines of black glands.

Hypericum maculatum



My star find from this verge were around 50 flowering spikes of Pennyroyal, a very uncommon plant in the Mint family. I suspect they were brought here by birds carrying or pooping out their seeds. There were some recorded on the opposite carriageway a while back but they have spread here since then.

To reliably separate them from Corn Mint, check the sepals. They should be hairy and the lower two being thinner and longer than the upper three.

Mentha pulegium


Here's a habitat shot which goes for the Pennyroyal and Imperforate St. John's-wort and a host of other species too.


That finishes off the first half of July, I hope you enjoyed this selection of plants. So until the end of the month, I will leave you. I hope you too find some lovely wild plants in your area too.

Take Care

Cornwall Botany - June 2024 Additions

 I managed a couple more trips before the end of June and I found some nice plants, so here's an additional blog to finish off June. I hope you like the selection.

Until I moved to Cornwall, I'd never seen Babington's Leek, but a few pop up here and there in coastal areas around Cornwall each year. This one was poking its way through Blackthorn scrub on the coast path at Trebetherick. They can grow to around three feet tall. You can find out more about it at https://plantatlas2020.org/atlas/2cd4p9h.kxp where it also explains the difference between the variants for you.

Allium ampeloprasum var babingtonii


It's time for carpets of flowering Betony again, with clifftop turf becoming a blaze of colour from these and other coastal species. Unlike the inland forms, these rarely grow much bigger than 6-8 inches tall.

Betonica officinalis


 Sheep's-bit looking perfectly blue as ever.

Jasione montana


I found two coastal sedges on the beach at Trebetherick too, in damp flushes where freshwater comes onto the beach. The first is Distant Sedge.

Carex distans



The second being Long-bracted Sedge, a more low growing sedge than the last with clumpy flattened utricles and a very long bract overtopping them.

Carex extensa



In those same damp flushes were stands of Common Scurvygrass. These plants are much bigger than Danish Scurvygrass and have more rounded leaves, see second photo below.

Cochlearia officinalis



The first Bell Heather coming into flower on the clifftops.

Erica cinerea


An arable field edge nearby had a few Weasel's Snout growing in them, definitely a great find.

Misopates orontium



Nearby were several Heath Groundsel plants just coming into flower. They can grow to around two feet tall and the flowers have small inrolled ray petals unlike normal Groundsel.

Senecio sylvaticus



Rock Sea-Spurrey was in flower on rocks along a beach. They are easy to tell apart from the other Sea Spurries, simply as their flowers are much larger than the other species and quite purple too. You won't find them growing in salt marshes either.

Spergularia rupicola



The last plants featured here for June were from a trip to Bolventor on the edge of Bodmin Moor. On a roadside wall were plenty of Wall-rue, Black Spleenwort and a few of these Rustyback Ferns.

Asplenium ceterach


On a rural road verge away from houses was a colony several metres long of a garden escaped Geranium species. It's the hybrid between French and Pencilled Cranesbills which I've seen a few times in the wild, but they were always pink with purple veins. So it was quite interesting finding a white variant.

Geranium x oxonianum



Fox and Cubs is an attractive plant that is also fairly common in Cornwall, usually on road verges and in churchyards. Here it was growing profusely along road verges on a slip road to the main A30.

Pilosella aurantiacum


I then went to some open access land nearby that included some boggy areas. Of note is that the OS map clearly showed the open access land but it was fenced off with a locked gate. As I approached it, I spoke to the landowner and explained what I wanted to do and he kindly let me in. I've often found the OS maps to be out of date and what was open access land is now private, so be warned.

Once in the boggy area, I saw lots of Heath Spotted Orchids, still in their prime, as being up high on the moor, they flower later than their lower altitude counterparts.

Dactylorhiza maculata


In amongst the Purple Moor Grass and abundant rushes were several flowering Marsh Willowherbs, perhaps the uncommonest and daintiest of our native Willowherb species.

Epilobium palustre




The first Bog Asphodels were in flower, shining like golden beacons in the bog.

Narthecium ossifragum




Both species of Cottongrass were in the bog, often growing right next to each other.

Eriophorum angustifolium - Common Cottongrass


 

Eriophorum vaginatum - Harestail Cottongrass


Marsh Woundwort was flowering in large numbers along the edge of the boggy area too, lovely.

Stachys palustris



Tufted Vetch adorning the road verges and hedgerows finish off my June offerings for Cornwall flora.

Vicia cracca



I hope you liked the selection of plants above, I've yet to go out in July due to several rainy days on the trot, but I'm sure I will find some nice plants out and about when the weather improves. Until then, take care and thank you for reading this blog.

Cornwall Botany - October 2024

 It's stayed mild for the entire month which has encouraged the summer plants to continue flowering, such as Rough Chervil, but also has...
