Basil Thyme

Clinopodium acinos

Basil Thyme used to be picked as a substitute for thyme, but it is now too rare to pick. Its distribution closely follows that of underlying chalk and limestone rock.

How to spot it

Like other members of the dead-nettle family, Basil Thyme is popular with bees and insects. At only 15 cm high, it produces whorls of violet flowers with white markings on the lower lip. Common Calamint and Wild Basil are closely related but are larger and with taller more dense flower spikes.

Where to spot it

Basil Thyme grows mainly in southern and eastern England and is very rare in Wales, Scotland and northeast England. It is also present in eastern Ireland where is it considered an alien species. It grows in open habitats in dry grassland, especially around rock outcrops and also in arable fields, where it is now rare. It can be found in quarries and waste ground where calcareous rocks and lime-rich soil has been exposed and roads and railways where lime has been applied. In Ireland, Basil Thyme grows on sandy and gravelly soils.

How’s it doing?

Basil Thyme is unfortunately in decline because of more efficient methods of weed control almost causing its complete extinction in arable habitat. Basil Thyme is only present on less intensively used arable land and in chalk and limestone grassland. Threats to grassland populations include the lack of bare ground which is required by this species to aid seed germination. In Ireland, sand and gravel extraction are the main causes of decline.

It is classified as ‘Vulnerable’ and is included as a species “of principal importance for the purpose of conserving biodiversity” under Sections 41 (England) and 42 (Wales) of the Natural Environment and Rural Communities Act 2006. Basil Thyme is also noted on the Scottish biodiversity list of species of principal importance for biodiversity conservation in The Nature Conservation (Scotland) Act 2004.

Other Species

Adder’s Tongue Spearwort

Ranunculus ophioglossifolius

How to spot it

Adder’s Tongue Spearwort is a pretty plant with small, bright yellow buttercup-like flowers. The leaves are pointed oval, quite unlike ordinary buttercup leaves. When submerged, the pale greenish-yellow leaves float to the surface like small water-lily leaves.

Where to spot it

Adder’s Tongue Spearwort can be found in wet or marshy places, often round the edges of field ponds. It prospers at the edge of cattle ponds in the churned-up mud. It’s a sensitive plant, requiring low competition, low water levels in summer, and plenty of rain in early winter.

Adder’s Tongue Spearwort is now found at only two sites in Gloucestershire, having previously grown in several parts of southern England. With human intervention, a sizeable population of plants flower and fruit every year.

How’s it doing?

Adder’s Tongue Spearwort is classified as Vulnerable and protected under Schedule 8 of the Wildlife and Countryside Act 1981, perhaps unsurprising given its exceedingly picky requirements.

It is mainly threatened by loss of grazing on pastures and commons, loss of muddy ponds, or overgrazing and excessive trampling too early in the year. Climate change with drier winters also causes drying out of small ponds. Without a mild, frost-free Autumn and enough rain to keep the ground moist for seedlings to develop, they can be uprooted by birds or killed by trampling livestock.

Things you might not know

  • The Latin name Ranunculus means ‘froglike’, referring to the plant’s preference for aquatic habitats.
  • The specific part of the scientific name, ophioglossifolius refers to the shape of the leaves that resemble the small fern Ophioglossum.
  • Adder’s Tongue Spearwort is at the northern edge of its range in Britain.
  • The two sites where it can be found in Gloucestershire are Badgeworth (hence its alternative name: the Badgeworth Buttercup) and Inglestone Common.

Other Species

Brooklime

Veronica beccabunga

How to spot it

Brooklime has delicate blue flowers held on fleshy stems, often forming lush clumps near water. The spikes of pretty blue flowers ascending in pairs from the leaf base are a clue that this plant is a member of the Speedwell family. Brooklime is a perennial sprawling herb with a dense mass of succulent leaves. Like many water plants, it has hollow stems which help to transfer oxygen to the roots.

Where to spot it

It grows at the waterline of riverbanks and in wet meadows, marshes, ponds, streams and ditches. It is found throughout the UK except in the Scottish Highlands.

How’s it doing?

Brooklime is doing well in its preferred habitats.

Things you might not know

  • Brooklime was used as a salad plant in much of northern Europe in the past.
  • It used to be eaten with watercress and oranges to help prevent scurvy.
  • Although edible, the leaves are bitter and the same precautions should be taken with them, as with watercress, in order to avoid liver fluke.

Other Species

Red Dead-nettle

Lamium purpureum

Red Dead-nettle is traditionally known as the ‘bumblebee flower’ in some British counties as bumblebees love it! Other names include ‘sweet archangel’ and ‘bad man’s posies’. Red Dead-nettle is related to the stinging nettle but has no sting – hence the ‘dead’ in ‘dead-nettle’.

How to spot it

Red Dead-nettle has whorls of pink-purple flowers clustered amongst leaves towards the top of the plant. The aromatic leaves are hairy, heart-shaped and have toothed edges. Some leaves near the top of the plant take on a purple tint. This plant can be mistaken for henbit dead-nettle which has similar flowers. They can be differentiated because Red Dead-nettle leaves have short petioles (leaf stalks).

Where to spot it

Found throughout the UK, Red Dead-nettle likes arable and waste land and can also be found in gardens, hedgerows and on roadsides.

Best time to spot it

Red Dead-nettle has a long flowering season that can begin in February and last until November.

Things you might not know

  • The generic name is from the Greek lamia meaning ‘devouring monster’. This refers to the helmet shape (galeate) of the flower which has the appearance of open jaws.
  • The vernacular name ‘Archangel’ may refer to their virtue of being non-stinging.
  • It is likely that this plant was introduced to Britain with early agriculture and evidence for it has been found in Bronze Age deposits.
  • The whole plant is astringent, diaphoretic, diuretic, purgative and styptic. In terms of traditional medicinal uses, dried leaves have been used as a poultice to stem hemorrhaging whilst fresh bruised leaves have been applied to external wounds and cuts. The leaves are also made into a tea and drunk to promote perspiration and discharge from the kidneys in treating chills.

Other Species

String-of-sausages Lichen

Usnea articulata 

  • Grey-green tassels of up to 1 m hanging down or draped across the substrate but rarely anchored to it.  
  • Main stems have inflated sections which are pinched at intervals, and so resemble a string of sausages. This is a key feature to look for as there are other pendulous Usnea species but none have this characteristic.

Habitat

It is most common in the south west’s temperate rainforest zone. 

Favouring well-lit conditions and dry, open situations, it is most often found in tree canopies or on lower branches where trees are well-lit, in woodland or on scattered trees in open moorland. You can also find it on the ground after stormy weather. 

Similar species

Other large, bearded lichens include Usnea ceratina, Usnea dasopoga and Usnea hirta but these lack the sausage-like lobes. 

Did you know

  • It is a Section 41 species which means that it is considered of “principal importance for the conservation of biodiversity in England” under Section 41 of the Natural Environment and Rural Communities Act (2006).
  • A clean air indicator, rare outside of south-west England’s rainforest zone. Highly sensitive to sulphur dioxide pollution, it was once much more widespread in Britain but now appears to be making a comeback, perhaps due to improved air quality and a warming climate. 

Distribution 

Largely restricted to south-western parts of the UK with most records in south-west England.

Where to find them?

Meadow Waxcaps (Hygrocybe pratensis) are a common find on cropped grassland and upland pastures. It appears from late August until December. Particularly in upland areas on acidic soil, the Meadow Waxcap is one of the few waxcap species that can tolerate small amounts of fertiliser being applied to its grassland habitat.

Did you know?

Two varieties of the Meadow Waxcap occur in BritainOne is apricot and the other is paler and almost white. It is a conspicuous and robust waxcap often persisting for several weeks.

Hart’s-tongue Fern

Asplenium scolopendrium

This evergreen plant has long, tongue shaped leaves with a pointy end.

Distribution

Widespread across Britain, except in the far north.

Habitat

Can be found in sheltered moist habitats such as woods, on hedge banks, in walls and in ditches.

Did you know?

  • The underside of the leaves have little marks reminiscent of centipedes legs, leading to the species name ‘scolopendrium’ (the Latin for centipede!)
  • A hart was an old name for a deer, so the plant was so-named as it specifically looks like a deer’s tongue.

Other Species

Ivy

Hedera helix

A evergreen woody climbing wild plant, commonly seen on old walls and tree trunks.

Ivy is often found carpeting the ground or growing up walls and trees.

Its flowers bloom in an umbrella-like spread. In fact the term for such a bloom – an ‘umbel’ – derives from the same source as umbrella – umbra, the Latin word for shade.

It’s leaves are dark green glossy above, paler below. On flowering shoots leaves are pointed oval.

Distribution

Widespread throughout the UK.

Habitat

Woods, hedgerows, rocks and walls. Very commonly found on tree trunks.

Best time to see

Flowers September to November.

Did you know?

  • Ivy is, of course, celebrated with holly in the Christmas Carol of the same name. Its symbolism, however, predates Christianity. As evergreen species both holly and ivy were seen as especially powerful during the leafless days of winter. Sprigs were said to ward off evil spirits and inside the home kept the house goblins at bay. Of the two, ivy – shapely and curvaceous – was said to represent the feminine as compared to the spiky, angular masculinity of holly.
  • Local names include Bentwood, Bindwood, Hibbin, Ivin, Ivery and the enchanting Love-Stone used in Leicestershire.
  • In the Highlands and Islands it has been used as protection, to keep evil away from milk, butter and the animals. Circlets of ivy alone, or ivy plaited with Rowan and honeysuckle were hung over the lintels of byres and put under milk vessels.
