Commonly known as New England aster, hairy Michaelmas-daisy, or Michaelmas daisy, it is a perennial, herbaceous plant usually between 30 and 120 centimeters tall and 60 to 90 cm wide.
OclemenaE.L.Greene, is a small genus of North American flowering plants in the aster tribe within the.
Symphyotrichum is a genus of over 100 species and naturally occurring hybrids of herbaceous annual and perennial plants in the composite family Asteraceae, most which were formerly treated within the genus Aster. The majority are endemic to North America, but several also occur in the West Indies, Central and South America, as well as in eastern Eurasia. Several species have been introduced to Europe as garden specimens, most notably New England aster and New York aster.
Senecio lamarckianus, the bois de chèvre, is a species of flowering plant in the aster family and a member of the genus Senecio. It is endemic to the island of Mauritius and is threatened by habitat loss.
Doellingeria is a genus of flowering plants in the aster family. It contains species formerly included in Aster but now considered to be a distinct genus. They are known commonly as tall flat-topped asters or whitetops.
Barkleyanthus is a monotypic genus of flowering plants in the aster family, Asteraceae, containing the single species Barkleyanthus salicifolius, a plant formerly classified in the genus Senecio. It is native to North and Central America, where its distribution extends from the southwestern United States to El Salvador. Its common names include willow ragwort, willow groundsel, Barkley's-ragwort, and jarilla.
Warionia is a genus in the dandelion tribe within the daisy family. The only known species is Warionia saharae, an endemic of Algeria and Morocco, and it is locally known in the Berber language as afessas, abessas or tazart n-îfiss. It is an aromatic, thistle-like shrub of ½–2 m high, that contains a white latex, and has fleshy, pinnately divided, wavy leaves. It is not thorny or prickly. The aggregate flower heads contain yellow disk florets. It flowers from April till June. Because Warionia is deviant in many respects from any other Asteraceae, different scholars have placed it hesitantly in the Cardueae, Gundelieae, Mutisieae, but now genetic analysis positions it as the sister group to all other Cichorieae.
Mairia is a genus of perennial herbaceous plants assigned to the daisy family. All species have leathery, entire or toothed leaves in rosettes, directly from the underground rootstock, and one or few flower heads sit at the top of the stems that carry few bracts. These have a whorl of white to mauve ray florets surrounding yellow disc florets in the centre. In general, flowering only occurs after the vegetation has burned down. The six species currently assigned to Mairia are endemic to the Western Cape and Eastern Cape provinces of South Africa. Some of the species are called fire daisy in English and vuuraster in Afrikaans.
Cavea is a low perennial herbaceous plant that is assigned to the daisy family. Cavea tanguensis is currently the only species assigned to this genus. It has a basal rosette of entire, slightly leathery leaves, and stems of 5–25 cm high, topped by bowl-shaped flower heads with many slender florets with long pappus and purplish corollas. The vernacular name in Chinese is 葶菊. It grows high in the mountains of China (Sichuan), Tibet, India (Sikkim), and Bhutan, and flowers in July and August.
Chiliotrichiopsis is a genus of flowering plants in the family Asteraceae. It is native to the Andes, where it is distributed in Peru, Bolivia, and Argentina. Species occur in the mountains up to 4200 meters in elevation.
Pericome caudata is a species of flowering plant in the aster family known by the common name mountain tail-leaf. It is native to the southwestern United States as far east as Colorado, Oklahoma, and Texas, as well as northern Mexico, where it grows in rocky habitat, often in hills and mountains, and sometimes in disturbed areas. It is a large, branching, leafy perennial herb or subshrub approaching 2 meters in maximum height. It is glandular, resinous, sparsely hairy, and aromatic. The leaves are somewhat triangular, sometimes with a few large teeth or sharp lobes, the blade measuring up to 12 centimeters long and borne on a petiole. The leaf size and shape is variable across the species' range. The inflorescence is a cluster of many flower heads each under a centimeter wide and filled with golden yellow disc florets. The Navajo used this plant for a variety of medicinal and ceremonial purposes.
Mairia crenata is a perennial herbaceous plant of mostly 2–15 cm (1–6 in) high that is assigned to the daisy family. It has a woody rootstock of up to 5 cm (2 in) long, from which brown, fleshy roots develop. The five to eighteen, hard and leathery, spoon-shaped leaves are in one to three rosettes, have a distinct main vein, blunt or pointy tip, often dark red or blackish margins with rounded teeth and a ½–2 cm (0.2–0.8 in) long stalk-like foot, often initially somewhat woolly hairy, on particularly the lower surface and the main vein, but this is easily rubbed off the shiny surfaces. Each rosette produces mostly one, sometimes up to four, mostly rusty or whitish woolly hairy, brown or dark red inflorescence stalks, usually 1½–15 cm long, each with two to eight, initially woolly, line-shaped to oval bracts, the lowest up to 3 cm (1.2 in), decreasing size further up, and carrying mostly one, rarely up to three flower heads. The flower heads have a bell-shaped involucre with about 40 bracts, sixteen to thirty three violet to white ray florets of about 1¼–1⅞ cm long, and many yellow disc florets. The species flowers anywhere between February and December but only after a fire has destroyed the overhead biomass or serious disturbance. It is an endemic species that is restricted to the Eastern Cape and Western Cape provinces of South Africa.
Felicia brevifolia is an evergreen, richly branched shrub of up to 11⁄2 m (5 ft) high, that is assigned to the daisy family. It has elliptic to wedge-shaped leaves, of between 1⁄2 and 11⁄2 cm long, green to gray-green, many with several teeth. The flower heads have about fifteen blue-violet ray florets, encircling many yellow disc florets. This species grows in southern Namibia and the west of South Africa.
Mairia coriacea is a perennial plant assigned to the daisy family. It has broad, tough and leathery, evergreen leaves. These have a narrowed foot and an entire margin or a few shallow, irregular teeth. They grow in a rosette directly from the rootstock. The plant produces flower heads with one whorl of white to mauve ray florets around many yellow disc florets, with one or few on top of a dark reddish, woolly stalk. Flower heads appear after the overhead vegetation burnt down, often destroying the leaves in the process. It can be found in the southern mountains of South Africa's Western Cape province. It is called leather leaves in English.
Mairia burchellii is a tufted perennial plant of up to 15 cm (6 in) assigned to the daisy family. It has narrow leaves of up to 5 mm (0.20 in) wide, with single main vein and an entire margin. Flower heads only occur after a fire has destroyed the standing vegetation, mostly in November or between February and June. The flower heads sit individually or with a few on the tip of a purplish stalk, with a few narrow bracts, and consist of a row of pinkish ray florets around many yellow disc florets. It can be found in the southwest of the Western Cape province of South Africa.
Mairia petiolata is a tufted, variably hairy, perennial plant of up to 15 cm (6 in) assigned to the daisy family. Its leaves are in a ground rosette, and have a stalk of mostly 2–5 cm long and an inverted egg-shaped to elliptic, 61⁄2–9 cm (2.6–4.6 in) long and 2–3 cm wide leaf blade, with a toothed margin. It mostly has two flower heads at the tip of the branches of each erect, dark reddish brown scape. The flower heads have a bell- to cup-shaped involucre that consists of 20–24, purplish, overlapping bracts in 3–4 whorls. These protect 12–16 pink, ray florets, surrounding many yellow disc florets. This species was only seen flowering once, in December. It is known from one location in the Langeberg, Western Cape province of South Africa.
Mairia robusta is a tufted, white-woolly, perennial, herbaceous plant of up to 30 cm (1 ft) high, that is assigned to the daisy family. It has large, robust, hard and leathery leaves, with a white woolly hairy, nontransparent underside, while the felty hairs on the top are lost with age. Only at a few occasions, flowers have been observed, in June, October and December, always after a fire. The flower heads sit individually at the at tip of white-woolly scapes, with 14–16 purplish pink to white ray florets surrounding a yellow disc. M. robusta is an endemic species that is restricted to rocky mountain slopes in the Western Cape province of South Africa.
Mairia hirsuta is a tufted perennial, herbaceous plant of up to 40 cm high, that is assigned to the daisy family. Most of its narrow to broad elliptic or inverted egg-shaped leaves are part of the basal rosette, have margin that is rolled under, with rounded or pointy teeth or with some peg-like extensions, lightly woolly on the upper surface and densely woolly on the underside, but always the green remains visible. Flower heads have been found from July to November, mostly after a fire or when the soil has been disturbed. The species can be found in the southern mountains of the Western Cape province of South Africa.
Felicia tenella is an annual, sometimes biennial, herbaceous plant that may be slightly woody at its base, of 5–70 cm tall, that is assigned to the daisy family. The species is very variable in size and hairiness. Its branches may be erect or ascending, and the leaves are narrowly line-shaped, 2–5 cm long and about 1 mm (0.04 in) wide. The leaves have a callous tip, lack visible nerves, and are mostly rigidly ciliate. The flower heads sit individually at the tip of stalks, have an involucre of three whorls of bracts, and about thirty light blue ray florets surrounding many yellow disc florets. Four subspecies are recognised. The species naturally occurs in the Northern Cape and Western Cape provinces of South Africa.
Felicia is a genus of small shrubs, perennial or annual herbaceous plants, with 85 known species, that is assigned to the daisy family. Like in almost all Asteraceae, the individual flowers are 5-merous, small and clustered in typical heads, and which are surrounded by an involucre of, in this case between two and four whorls of, bracts. In Felicia, the centre of the head is taken by yellow, seldom whitish or blackish blue disc florets, and is almost always surrounded by one single whorl of mostly purple, sometimes blue, pink, white or yellow ligulate florets and rarely ligulate florets are absent. These florets sit on a common base and are not individually subtended by a bract. Most species occur in the Cape Floristic Region, which is most probably the area where the genus originates and had most of its development. Some species can be found in the eastern half of Africa up to Sudan and the south-western Arabian peninsula, while on the west coast species can be found from the Cape to Angola and one species having outposts on the Cameroon-Nigeria border and central Nigeria. Some species of Felicia are cultivated as ornamentals and several hybrids have been developed for that purpose.
