Illecebrum is a monotypic genus in the family Caryophyllaceae. It contains the single species Illecebrum verticillatum, which is a trailing annual plant native to Europe, with whorls of small white flowers borne in the axils of the paired leaves.
Illecebrum verticillatum is native to much of Europe, from the western Iberian Peninsula to Poland; [1] it is rare in Great Britain, [2] and its northernmost station is in Denmark. [1] It has also been introduced species to at least one site in New Zealand and one site in Western Australia. [3]
Illecebrum verticillatum produces procumbent or decumbent (trailing) stems that may be up to 20 cm (7.9 in) high. It has ovate leaves arranged in opposite pairs along the stem. The small flowers are clustered in the axils of the leaves; their petals are much smaller than the white sepals. [2]
Illecebrum verticillatum was first described by Carl Linnaeus in his 1753 Species Plantarum . It has sometimes been placed in a family of its own, Illecebraceae, but is usually placed in the family Caryophyllaceae. [3] The genus name Illecebrum derives from the Latin word illecebra , meaning "enticement", although it is unclear how the name came to be applied to a plant such as I. verticillatum. [3] The specific epithet verticillatum means "whorled", [4] in reference to the arrangement of the flowers. The plant is sometimes referred to in published works as whorled knotweed or coral necklace, although it is unclear if these purported common names are actually used in practice. [3]
Caryophyllaceae, commonly called the pink family or carnation family, is a family of flowering plants. It is included in the dicotyledon order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. It is a large family, with 81 genera and about 2,625 known species.
Anagallis is a genus of about 20–25 species of flowering plants in the family Primulaceae, commonly called pimpernel. The scarlet pimpernel referred to in literature is part of this genus. The botanical name is from the Greek ana and agállein, and it refers to the opening and closing of the flowers in response to environmental conditions.
Sherardia is a monotypic genus of flowering plants in the family Rubiaceae. The genus contains only one species, Sherardia arvensis, the (blue) field madder, which is widespread across most of Europe and northern Africa as well as southwest and central Asia and Macaronesia. It is also reportedly naturalized in Australia, New Zealand, Taiwan, Kerguelen, Ethiopia, Sudan, southern Africa, Mexico, Costa Rica, South America, Bermuda, Cuba, Haiti and much of Canada and the United States.
Elodea canadensis is a perennial aquatic plant, or submergent macrophyte, native to most of North America. It has been introduced widely to regions outside its native range and was first recorded from the British Isles in about 1836.
Teucrium is a cosmopolitan genus of flowering plants in the mint family Lamiaceae, commonly known as germanders. Plants in this genus are perennial herbs or shrubs, with branches that are more or less square in cross-section, leaves arranged in opposite pairs, and flowers arranged in thyrses, the corolla with mostly white to cream-coloured, lobed petals.
Silene dioica, known as red campion and red catchfly, is a herbaceous flowering plant in the family Caryophyllaceae, native to Europe and introduced to the Americas.
Silene nutans is a flowering plant in the genus Silene, most commonly known as Nottingham catchfly.
A strobilus is a structure present on many land plant species consisting of sporangia-bearing structures densely aggregated along a stem. Strobili are often called cones, but some botanists restrict the use of the term cone to the woody seed strobili of conifers. Strobili are characterized by a central axis surrounded by spirally arranged or decussate structures that may be modified leaves or modified stems.
Rabelera holostea, known as greater stitchwort, greater starwort, and addersmeat, is a perennial herbaceous flowering plant in the family Caryophyllaceae. It was formerly placed in the genus Stellaria, as Stellaria holostea, but was transferred to the genus Rabelera in 2019 based on phylogenetic analyses. It is the only species in the genus Rabelera. Greater stitchwort is native to Western and Central Europe, including the British Isles.
Kennedia is a genus of thirteen species of flowering plants in the pea family Fabaceae and is endemic to Australia. Plants in this genus are prostrate or climbing perennials with trifoliate leaves and large, showy, pea-like flowers. There are species in all Australian states.
Hardenbergia is a genus of three species of flowering plants in the pea family, Fabaceae and is endemic to Australia. Plants in this genus are climbing or trailing herbs or subshrubs with pinnate leaves with one, three or five leaflets and groups of violet, white or pinkish flowers in pairs or small clusters in leaf axils. Species of Hardenbergia occur in all Australian states and in the Australian Capital Territory.
Aptenia was a small genus of flowering plants in the family Aizoaceae, which as of January 2024 was treated as a synonym of the genus Mesembryanthemum. Species formerly placed in the genus are native to southern Africa. The genus name is from the Greek a- (not) and ptenos (winged), and refers to the wingless fruit capsules.
Utricularia dichotoma, commonly known as fairy aprons, is a variable, perennial species of terrestrial bladderwort. It is a widespread species with mauve or purple fan-shaped flowers on a slender stalk and usually grows in wet locations.
Honckenya peploides, the sea sandwort (UK) or seaside sandplant (Canada), is the only species in the genus Honckenya of the plant family Caryophyllaceae. Other common names include sea chickweed, sea pimpernal, sea-beach sandwort, and sea purslane. The scientific name is often spelled "Honkenya", and is named after the German botanist Gerhard August Honckeny. This plant has a circumboreal distribution.
Myriophyllum verticillatum, the whorl-leaf watermilfoil or whorled water-milfoil, is a native to much of North America, North Africa, and Eurasia. It closely resembles another native milfoil, called northern water milfoil Whorled water milfoil is also easily confused with four types of invasive milfoils: Eurasian water milfoil, Variable water-milfoil, Parrot feather, and hybrid water milfoil.
Engellaria obtusa is a species of flowering plant in the family Caryophyllaceae known by the common names Rocky Mountain chickweed, blunt-sepaled starwort, and obtuse starwort. It is the sole species in genus Engellaria. It is native to western North America, from British Columbia and Alberta to California to Colorado, where it grows in moist areas in forests and on mountain slopes.
Saxifraga aspera is a species of saxifrage known by the common name of rough saxifrage. In German it is known as Rauhhaariger Steinbrech. It is placed in section Trachyphyllum of the genus Saxifraga. There are two subspecies, Saxifraga aspera subsp. aspera and Saxifraga aspera subsp. micrantha. It is a plant of the pan-Arctic tundra and is also found in Europe at moderately high altitudes in the Alps, Pyrenees and northern Apennines.
Hemiphora is a genus of five species of flowering plants in the mint family, Lamiaceae and is endemic to Western Australia. Plants in this genus are woolly shrubs with warty, hairy leaves and with five petals joined to form a tube-shaped flower with four stamens. These species are similar to those in the genus Chloanthes in that the base of the leaves extends down the stem. They differ from Chloanthes, in that the leaves only extend a short distance down the stem.
Tordylium maximum, known as hartwort, is an annual or biennial flowering plant in the carrot family (Apiaceae).
Stellaria alsine, the bog stitchwort, is a species of herbaceous perennial flowering plant in the carnation family Caryophyllaceae. It grows in bogs and marshes in Europe and parts of North America.
