Lotus pedunculatus (formerly Lotus uliginosus), the big trefoil, [1] greater bird's-foot-trefoil [2] or marsh bird's-foot trefoil, is a member of the pea family (Fabaceae).
It is a herbaceous perennial growing throughout Europe in damp, open locations. As one common name suggests, it is a larger plant than related Lotus species, growing 20–80 cm (8–30 in) tall, with leaflets 10–25 mm (0.4–1 in) long and 10–20 mm (0.4–0.8 in) broad. Five to twelve golden-yellow flowers 10–18 mm (0.4–0.7 in) long are borne in an umbel at the tip of the upright stem.
Unlike related species, the stem is always hollow, and the sepals turn back at their tips – these sepal tips form a characteristic "green star" at the end of the flower bud. The peak flowering period in the United Kingdom is June and July. [3]
Lotus pedunculatus has been introduced to the western side of the United States and is now a prevalent weed in irrigated lawns and draining waste areas. Due to this it is considered a problem in gardens across the west and as a legume promotes other weed growth as a nitrogen fixer. [4]
Lotus pedunculatus occurs in a wide range of neutral, damp, open habitats, including certain fen-meadow plant associations such as Juncus subnodulosus-Cirsium palustre fen-meadow habitat. [5]
Lotus pedunculatus is also a host plant for ovipositioning of the wood white butterfly, Leptidea sinapis. [6]
Filipendula ulmaria, commonly known as meadowsweet or mead wort, is a perennial herbaceous plant in the family Rosaceae that grows in damp meadows. It is native throughout most of Europe and Western Asia. It has been introduced and naturalised in North America.
Cirsium is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera in having a seed with a pappus of feathered hairs on their achenes. The other genera have a pappus of simple unbranched hairs.
Cirsium vulgare, the spear thistle, bull thistle, or common thistle, is a species of the Asteraceae genus Cirsium, native throughout most of Europe, Western Asia, and northwestern Africa. It is also naturalised in North America, Africa, and Australia and is an invasive weed in several regions. It is the national flower of Scotland.
Cirsium palustre, the marsh thistle or European swamp thistle, is a herbaceous biennial flowering plant in the family Asteraceae.
Lotus corniculatus is a flowering plant in the pea family Fabaceae, native to grasslands in temperate Eurasia and North Africa. Common names include common bird's-foot trefoil, eggs and bacon, birdsfoot deervetch, and just bird's-foot trefoil, though the latter name is often also applied to other members of the genus.
Lathyrus pratensis or meadow vetchling, yellow pea, meadow pea and meadow pea-vine, is a perennial legume that grows to 1.2 m in height.
Leptidea sinapis, or the wood white butterfly of the family Pieridae, is a small white butterfly that is mainly found in England, Ireland, and Northern Europe. The butterfly has white wings with grey or yellow markings near the center or tip of the wing. It flies slowly and low over its shrubbery habitat. Males initiate courtship with females and can mate multiply, while females tend to only mate once in their lifetime.
Holcus lanatus is a perennial flowering plant in the grass family Poaceae. The specific epithet lanatus is Latin for 'woolly' which describes the plant's hairy texture. Common names include Yorkshire fog, tufted grass, and meadow soft grass. In North America, where it is an invasive species, names include velvet grass and common velvet grass.
Lambert's Castle is an Iron Age hillfort in the county of Dorset in southwest England. Since 1981 it has been designated as a Site of Special Scientific Interest (SSSI) on account of its geology, archaeology and ecology. The hillfort is designated a scheduled monument together with a bowl barrow, the sites of a post-medieval fair and a telegraph station. The site was on the Heritage at Risk Register but was removed in 2022 as a result of the Hillforts and Habitats Project.
Equisetum palustre, the marsh horsetail, is a perennial herbaceous pteridophyte belonging to the division of horsetails (Equisetopsida). It is widespread in cooler regions of North America and Eurasia.
Comarum palustre, known by the common name marsh cinquefoil, also purple marshlocks and swamp cinquefoil, is a waterside rhizomatous subshrub. It has a circumboreal distribution, occurring throughout cool temperate Asia, Europe, and North America, particularly in northern regions. It is most commonly found on lake shores, marshy riversides and stream margins, often partly submerged with foliage floating. It is a parent of some Fragaria–Comarum hybrids, ornamental plants produced by crossing with strawberries.
Selinum carvifolia is a flowering plant of the genus Selinum in the family Apiaceae. The specific name carvifolia signifies 'having leaves resembling those of Caraway'. It is a plant of fens and damp meadows, growing in most of Europe, with the exception of much of the Mediterranean region, eastwards to Central Asia. Its common name in English is Cambridge milk parsley, because it is confined, in the UK, to the county of Cambridgeshire and closely resembles milk parsley, an umbellifer of another genus, but found in similar habitats. The two plants are not only similar in appearance, but also grow in similar moist habitats, although they may be told apart in the following manner: P. palustre has hollow, often purplish stems, pinnatifid leaf lobes and deflexed bracteoles; while S. carvifolia has solid, greenish stems, entire or sometimes lobed leaf-lobes and erecto-patent bracteoles. Also, when the two plants are in fruit, another difference becomes apparent: the three dorsal ridges on the fruit of S. carvifolia are winged, while those on the fruit of P. palustre are not. Yet a further difference lies in the respective leaflets of the plants : those of Peucedanum palustre are blunt and pale at the tip, while those of Selinum carvifolia are sharply pointed and of a darker green. S. carvifolia used also to occur in the English counties of Nottinghamshire and Lincolnshire but is now extinct in both. Growing in only three small Cambridgeshire fens, it is one of England's rarest umbellifers. It is naturalized in the United States, where it is known by the common name little-leaf angelica.
Jockey fields is an 18.05 hectares biological site of Special Scientific Interest at Walsall Wood, in the West Midlands. The site was notified in 1994 under the Wildlife and Countryside Act 1981 and is currently managed by the Country Trust.
Lathyrus palustris is a species of wild pea known by the common name marsh pea. It is native to Europe, Asia, and North America. It is a perennial herb with leaves made up of oval-shaped or oblong leaflets a few centimeters long. It has branched, coiled tendrils. The plant bears an inflorescence of two to eight pinkish purple pea flowers each up to two centimeters wide. The fruit is a dehiscent legume pod.
Purple moor grass and rush pastures is a type of Biodiversity Action Plan habitat in the UK. It occurs on poorly drained neutral and acidic soils of the lowlands and upland fringe. It is found in the South West of England, especially in Devon.
The Juncus subnodulosus–Cirsium palustre fen-meadow is a plant association characteristically found on damp ground in portions of western Europe. This type of fen-meadow appears to have co-evolved with human agriculture in Europe since the earlier Holocene.
Carex disticha is a Eurasian species of sedge known as the brown sedge or, in North America, tworank sedge.
Carex acutiformis, the lesser pond-sedge, is a species of sedge.
NVC community M23 is one of the mire communities in the British National Vegetation Classification system.
Hypericum undulatum, the wavy St Johns Wort, is a herbaceous perennial flowering plant native to western Europe and northern Africa. The specific name undulatum is Latin, meaning "wavy" or "undulated", referring, just as the common name, to the wavy leaf margins of the herb. The plant has a diploid number of 16 or 32.
