National Plant Monitoring Scheme is a habitat-based plant monitoring scheme developed and run by BSBI, JNCC, Plantlife & UKCEH. The scheme would not be possible without our fab survey volunteers!

Species spotlight. Selfheal - Prunella vulgaris is common, forming patches with creeping runners on neutral to calcareous soils in grasslands, woodland rides & lawns. Oblong flower heads with small purple flowers & purplish bracts are held erect on square stems. Photo Sue McBean

Species spotlight. Carline Thistle - Carlina vulgaris is found in dry calcareous grasslands. It has purple tinged stems & composite flowers surrounded by a ring of pale bracts that open & shine golden. Dark purple florets wither leaving conspicuous orange scales. 📷 Ava Marley

Species spotlight. Broad-leaved Dock - Rumex obtusifolius is our commonest dock. It has large leaves with heart shaped bases & leaf veins are rough with tiny finger-like projections below. In fruit tepals usually have a few teeth & one rounded wart. Photo: Ava Marley

Species spotlight. Common Ragwort - Jacobaea vulgaris has yellow daisy-like flowers & highly divided stem leaves. Flower heads are often held in dense, flat-topped clusters, unlike Oxford and Hoary Ragwort which have a looser, more open arrangement. Photo Ava Marley

Species Spotlight: Red Clover - Trifolium pratense is common in all types of grassland. It has almost stalkless flower heads, with a pair of leaves just below, unlike the very similar looking but rarer Zigzag Clover which has a stalk to the flower head. Photo Suzanne Farmer

Species Spotlight: Harebell - Campanula rotundifolia is found in dry, sunny, low nutrient habitats on both acidic & alkaline soils. Although the basal leaves are rounded in shape they wither early, & the upper leaves are narrow & linear-lanceolate. Photo: Sue McBean

Species Spotlight: Bulrush - Typha latifolia grows in tall dense stands, favouring nutrient-rich & still water margins. Leaves are wide & glaucous, & there is no gap between the brown cylindrical female flower spike & the male flower spike above. Photos S. Farmer & N. Esselin

Species Spotlight: The leaves of Common Milkwort Polygala vulgaris are alternately arranged, unlike the similar looking Heath Milkwort which has its lower leaves in pairs. The leaves increase in size from the woody base towards the tip of the stem. Photo: Plantlife

Species spotlight. Marsh Arrowgrass - Triglochin palustris grows in damp vegetation usually on alkaline soils, & is slender & grass-like. Flowers are small, in a long spike. Fruits break up into 3 segments, unlike Sea Arrowgrass with fruits breaking up into 6. 📷: S. Shuttleworth

Species spotlight. Red Bartsia - Odontites vernus has very similar leaves to Yellow Rattle. To differentiate them when they are not flowering, look at the stems, which are often washed purple in Red Bartsia & lack the black streaks seen in Yellow Rattle. Photo: Ava Marley

Species spotlight. Flowers of Hop Trefoil - Trifolium campestre may be differentiated from similar Lesser Trefoil by the standard petals, which are broad and flatter in Hop Trefoil but fold sharply downwards in Lesser Trefoil. Both ripen to hop-like heads. Photo: Ava Marley

We're in for yet more dry conditions please take care if you're out on your survey plots. Data will be important in showing the effect of this unprecedented summer on our plant communities, but please only head out if it's safe to do so and be alert to the risk of wildfires.

Species spotlight Common Meadow-rue - Thalictrum flavum is found on damp, alkaline soils. Frothy masses of tiny white flower heads are held above highly divided leaves. Flowers have many stamens, with long filaments & yellow anthers. Photo: Andrew Gagg

Look out for the reddish-purple flowers of Betony - Betonica officinalis on verges, grassy heaths & meadows this month. Two bluntly toothed leaves lie just below the spike of whorled flowers, angled downwards at 45°. Photo: Andrew Gagg

Species Spotlight Sea Aster Tripolium pannonicum grows in salt marshes & other brackish coastal environments. Two varieties occur, flowers of one resembling a Michaelmas Daisy with both yellow disc & blue ray florets, the other with yellow disc florets only. Photo: Ava Marley

Species Spotlight Lesser Butterfly Orchid - Platanthera bifolia has two strictly parallel pollinia in the centre of the flower, which are close together & about 2mm long, compared to the divergent, wider spaced & 3-4mm long pollinia in the Greater Butterfly Orchid. 📷 C Harris

Species Spotlight Bog Asphodel Narthecium ossifragum has spikes of starry yellow flowers arising from iris-like leaves. Turning a deep orange in fruit, it forms patches of autumn colour in mires, flushes and wet heathland. Photo: Ava Marley

Species Spotlight Field Scabious Knautia arvensis can be distinguished from the similar Small Scabious by the 4 rather than 5 lobes to each individual flower corolla & the rougher, less finely cut stem leaves. It also lacks papery membranes on its seed heads. Photo: Ava Marley

Species Spotlight Juniper Juniperus communis is a native evergreen conifer. Needle-like leaves with a broad white band on the upper side are borne in whorls of 3. Fruits are berry-like cones, ripening to purple-black and used to flavour gin. Photo: Gower Peninsula Bob Gibbons

There are still spaces available to to join us near Helston, Cornwall on Friday 17th July. Experts from Budding Nature will lead this FREE one-day workshop focussing on coastal habitat species. Booking required. See our training events page or email support@npms.org.uk

Take care in this extreme hot weather. Surveys can wait until heat levels drop, but if you are out on your NPMS square please try to spread surveys out over several days, take regular shade breaks, & go prepared Sunscreen 🌞 Hat (sombrero?) 🤠 Water 💦 Photo: Roger Butterfield

Species Spotlight - Himalayan Balsam Impatiens gladulifera forms tall dense stands, usually near water. Leaves are opposite or 3-whorled, with sharp, often red gland-tipped teeth. Pink/purple flowers dangle, later developing into explosive seed capsules. Photo: Sue McBean

Species Spotlight - Wood Crane’s-bill Geranium sylvaticum is a rhizomatous perennial of unimproved meadows and open woodland mainly in upland areas. Flowers are purplish with white centres and leaves are deeply cut into 7 broad, toothed lobes. Photo: Andy Jennings-Giles

Species Spotlight - Hedge Bedstraw - Galium album has whorls of 6-8 leaves around four-angled stems & sprays of small white flowers with four petals that taper to fine points. Similar Heath Bedstraw is found in acidic habitats, petals blunt or with tiny points. 📷Sue Harris

Species Spotlight - Dwarf Spurge Euphorbia exigua is a scarce annual arable weed found on light, often base rich soils mainly in the south & southeast. Small but bushy, it has narrow grey-green strap-shaped leaves on well-branched stems. Photo: Bob Gibbons

It's National #VolunteersWeek & the BIGGEST thank you goes out to our brilliant NPMS survey volunteers, verifiers, data entry & photography volunteers. We now have over 1300 squares with associated data! You make this scheme the success that it is #NPMSVolunteers #CitizenScience

Species Spotlight - Spindle Euonymus europaeus is flowering this month, in hedgerows, scrub & woods on base-rich soils. Twigs are green & four-angled. Distinctive fruits appear in autumn, pink capsules splitting to show bright orange seeds. Photo: Ava Marley

Species Spotlight - Dropwort Filipendula vulgaris is found in grassland on base-rich soils. The pink buds and creamy white flowers form triangular-shaped clusters. Leaves have interspersed large and small coarsely toothed leaflets, and smell of antiseptic. Photo: Bob Gibbons
