Jacobaea incana, the grey ragwort, is a species of Jacobaea in the family Asteraceae.
Jacobaea incana can reach a height of 5–15 centimetres (2.0–5.9 in). This perennial herbaceous plant has a short stem and basal leaves arranged in a rosette. They are silver-gray green, thin, spatulate to broadly ovate, pinnate and hairy. This plant produces corymbs of yellow to orange-yellow flowers of about 13–14 millimetres (0.51–0.55 in). They bloom from June to August.
This species is widespread in the Eastern Alps to the Apennines and the Carpathians.
Grey ragwort can be found on stony meadows, on rocky places and moraines at elevation of 1,700–2,600 metres (5,600–8,500 ft) above sea level.
Senecio is a genus of the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific Latin genus name, Senecio, means "old man."
Jacobaea vulgaris, syn. Senecio jacobaea, is a very common wild flower in the family Asteraceae that is native to northern Eurasia, usually in dry, open places, and has also been widely distributed as a weed elsewhere.
Senecio vulgaris, often known by the common names groundsel and old-man-in-the-spring, is a flowering plant in the daisy family Asteraceae. It is an annual herb, native to Europe and widely naturalised as a ruderal species in suitable disturbed habitats worldwide.
Alnus incana, the grey alder or speckled alder, is a species of tree in the birch family, with a wide range across the cooler parts of the Northern Hemisphere.
Colias croceus, clouded yellow, is a small butterfly of the family Pieridae, that is, the yellows and whites.
Jacobaea maritima, commonly known as silver ragwort, is a perennial plant species in the genus Jacobaea in the family Asteraceae, native to the Mediterranean region. It was formerly placed in the genus Senecio, and is still widely referred to as Senecio cineraria; see the list of synonyms (right) for other names.
Banksia incana, commonly known as the hoary banksia, is a species of shrub that is endemic to the south-west of Western Australia. It has hairy stems, narrow linear leaves, heads of bright yellow flowers and later, up to thirty-six follicles covered with greyish hairs in each head.
Banksia sphaerocarpa, commonly known as the fox banksia or round-fruit banksia, is a species of shrub or tree in the plant genus Banksia. It is generally encountered as a 1–2 m (3.3–6.6 ft) high shrub, and is usually smaller in the north of its range. This species has narrow green leaves, and brownish, orange or yellow round flower spikes which may be seen from January to July. It is widely distributed across the southwest of Western Australia, growing exclusively in sandy soils. It is usually the dominant plant in scrubland or low woodland. It is pollinated by, and is a food source for, birds, mammals, and insects.
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.
Ragwort may refer to a number of plant species:
Longitarsus jacobaeae is a species of flea beetle known as the tansy ragwort flea beetle. It is used as an agent of biological pest control against the nectar-rich noxious weed known as ragwort.
Anachloris subochraria is a species of moth of the family Geometridae. It is found in New Zealand and the southern half of Australia including Tasmania and from Queensland across to Western Australia. This moth is day flying and can be found in New Zealand on the wing between November and April.
Hibbertia incana, commonly known as prickly Guinea-flower, is a small shrub that is native to Australia. It grows to between 0.2 and 1.5 metres high and has yellow flowers which appear between October and December in the species native range.
Cirsium erisithales, the yellow thistle or yellow melancholy thistle, is a perennial herbaceous plant in the thistle tribe within the sunflower family.
Senecio ovatus, common name wood ragwort, is a perennial herbaceous plant belonging to the family Asteraceae.
Jacobaea aquatica or Senecio aquaticus, the water ragwort or marsh ragwort, is a plant of the family Asteraceae. It is a perennial or biennial plant: young plants form a rosette near the ground, eventually producing a taller flowering shoot with many bright yellow flower heads, each with prominent ray florets. It grows in damp, grazed grassland, especially where there has been some disturbance.
Melaleuca incana, commonly known as grey honey-myrtle, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia and is naturalised in the south of Victoria in Australia. It is commonly grown as a garden plant and produces large numbers of white or creamy yellow flowers, sometimes highly scented, in spring.
Melaleuca incana subsp. incana, commonly known as grey honey-myrtle, is a plant in the myrtle family Myrtaceae which is endemic to the south-west of Western Australia and is naturalised in the south of Victoria in Australia. It is commonly grown as a garden plant and produces large numbers of white or creamy yellow flowers in early spring.
Melaleuca incana subsp. tenella is a plant in the myrtle family Myrtaceae which is endemic to the south coast of Western Australia. It was formerly known as Melaleuca tenella Benth. but was reduced to a subspecies in 1998. It is similar to M. incana subsp. incana except in the form of the plant, the size and shape of its leaves, its flowering time and distribution.
