Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels.
Senecio vulgaris, often known by the common names groundsel and old-man-in-the-spring, is a flowering plant in the family Asteraceae. It is an annual herb, native to Europe and widely naturalised as a ruderal species in suitable disturbed habitats worldwide.
The genus Ophrys is a large group of orchids from the alliance Orchis in the subtribe Orchidinae. They are widespread across much of Europe, North Africa, Caucasus, the Canary Islands, and the Middle East as far east as Turkmenistan.
Heracleum sphondylium, commonly known as hogweed, common hogweed or cow parsnip, is a herbaceous perennial or biennial plant, in the umbelliferous family Apiaceae that includes fennel, cow parsley, ground elder and giant hogweed. It is native to Europe and Asia. The common name eltrot may also be applied, but is not specific to this species. Umbelliferous plants are so named because of the umbrella-like arrangement of flowers they produce. The North American species Heracleum maximum is sometimes included as a subspecies of H. sphondylium.
Anthyllis is a genus of flowering plants in the family Fabaceae. This genus contains both herbaceous and shrubby species and is distributed in Europe, the Middle East and North Africa. The most widespread and familiar species is A. vulneraria, a familiar grassland flower which has also been introduced to New Zealand.
Hieracium umbellatum, the Canadian hawkweed, Canada hawkweed, narrowleaf hawkweed, or northern hawkweed, is a flowering plant in the daisy family Asteraceae.
Senecio ampullaceus, also known as Texas ragwort, Texas squaw-weed, Texas groundsel, and Texas butterweed, is a species of Senecio in the family Asteraceae, receiving its Latin name ampullaceus from its flask shaped flower-head. It is recommended for landscape use in its native Texas.
Senecio squalidus, known as Oxford ragwort, is a flowering plant in the daisy family Asteraceae. It is a yellow-flowered herbaceous plant, native to mountainous, rocky or volcanic areas, that has managed to find other homes on man-made and natural piles of rocks, war-ruined neighborhoods and even on stone walls. These habitats resemble its well drained natural rocky homeland. The plants have spread via the wind, rail and the activities of botanists. The travels of this short-lived perennial, biennial, or winter annual make it a good subject for studies of the evolution and ecology of flowering plants.
Senecio eboracensis, the York groundsel or York radiate groundsel, is a flowering plant in the daisy family Asteraceae. It is a self-pollinating hybrid species of ragwort and one of only six new plant species to be discovered in either the United Kingdom or North America in the last 100 years. It was discovered in 1979 in York, England growing next to a car park and formally described in 2003. Like many of the Senecio genus it can be found growing in urban habitats, such as disturbed earth and pavement cracks and this particular species only in York and between a railway and a car park.
Senecio gallicus, an annual plant of the genus Senecio and family Asteraceae, is a species that colonizes isolated habitats with difficult environmental conditions. It is widespread across southern France and the Iberian Peninsula in deserts and xeric shrublands, on steppes and salty dry coastal plains. S. gallicus is playing a predominant role in shaping patterns of genetic structure by presenting models of historical associations among population rather than patterns of ongoing gene flow.
Hieracium lachenalii, also known as common hawkweed or yellow hawkweed, is a species of plant in the dandelion tribe within the sunflower family. It is native to Europe but has become established as a weed in Australia and parts of North America. The species was widely known for many years as H. vulgatum, but more recent studies have indicated that the two names represent the same species. The name H. lachenalii was coined in 1802, H. vulgatum in 1819, so the older name is to be used.
Senecio congestus, also known by its common names swamp ragwort, northern swamp groundsel, marsh fleabane, marsh fleawort, clustered marsh ragwort and mastodon flower, a herbaceous member of the family Asteraceae and the genus Senecio, can be seen most easily when its bright yellow umbel flowers appear from May to early July standing 3 to 4 feet along marshes, stream banks and slough areas where it likes to grow.
Senecio angulatus, also known as creeping groundsel and Cape ivy, is a succulent flowering plant in the family Asteraceae that is native to South Africa. Cape ivy is a scrambling and a twining herb that can become an aggressive weed once established, making it an invasive species. It has been naturalised in the Mediterranean Basin, where it is grown as an ornamental plant for its satiny foliage and sweet-scented flowers.
Senecio vernalis is one of the European species of Senecio, an annual that is also known as eastern groundsel. While it has been long classified as Senecio vernalis, this species has more recently been described as a subspecies of Senecio leucanthemifolius and is now included by some in that species.
Senecio leucanthemifolius is a plant common in sea-side in Mediterranean area.
Juncus acutus, the spiny rush, sharp rush or sharp-pointed rush, is a flowering plant in the monocot family Juncaceae found throughout the Americas, Northern and Southern Africa, Western and Southern Europe and West Asia.
Forsskaolea tenacissima is a member of the non-stinging nettles genus Forsskaolea and is in the same family as the stinging kind, Urticaceae. Described as "looking like a tough character that does not want or need a caress", F. tenacissima makes its home where not many plant species survive, in stony soils, road edges, in the gravel wadi and "in the rock crevices and water-receiving depressions" above the stone pavements of the Hamadas.
Salix pedicellata is a species of willow. It is a shrub or small tree to about 6–8 m tall, native around the Mediterranean Sea from Portugal to Lebanon and Syria in the north and from the Canary Islands to Tunisia in the south. Salix canariensis may be treated as a subspecies of S. pedicellata.
Romulea columnae, the sand crocus, is a herbaceous perennial in the family Iridaceae. It is a small plant, with thin narrow leaves, and small scape which has small pink, pale purple or violet pointed flowers with darker veining and a gold or yellow throat. It is native to a wide area ranging from western Europe to the Mediterranean.
Juncus alpinoarticulatus, called the northern green rush and the alpine rush, is a species of flowering plant in the genus Juncus, with a circumboreal distribution. It prefers wet sandy soils, peat bogs, acidic fens, and ditches.
