Eurybia divaricata, commonly known as the white wood aster, is an herbaceous plant native to eastern North America. It occurs in the eastern United States, primarily in the Appalachian Mountains, though it is also present in southeastern Canada, but only in about 25 populations in the provinces of Ontario and Quebec. In the U.S. it is abundant and common, but in Canada it is considered threatened due to its restricted distribution. It can be found in dry open woods as well as along wood-edges and clearings. The species is distinguished by its flower heads that have yellow centers and white rays that are arranged in flat-topped corymbiform arrays, emerging in the late summer through fall. Other distinguishing characteristics include its serpentine stems and sharply serrated narrow heart-shaped leaves. The white wood aster is sometimes used in cultivation in both North America and Europe due to it being quite tough and for its showy flowers.

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.
Gorteria diffusa is a highly variable, small annual herbaceous plant or rarely a shrublet 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 are surrounded by an involucre, consisting of in this case several whorls of bracts, which are merged at their base. In G. diffusa, the centre of the head is taken by relatively few male and bisexual yellow to orange disc florets, and is surrounded by one complete whorl of 5–14 infertile cream to dark orange ray florets, sometimes with a few ray florets nearer to the centre. None, some or all of them may have darker spots at their base. The fruits remain attached to their common base when ripe, and it is the entire head that breaks free from the plant. One or few seeds germinate inside the flower head which can be found at the foot of plants during their first year. The species flowers between August and October. It is called beetle daisy in English and katoog in Afrikaans. It can be found in Namibia and South Africa.
Helianthus nuttallii subsp. parishii is a subspecies of the species Helianthus nuttallii in the genus Helianthus, family Asteraceae. It is also known by the common names Los Angeles sunflower and Parish's sunflower. This subspecies has not been seen, in the wild or in cultivation, since 1937.
Felicia josephinae is a roughly hairy annual herbaceous plant of 15–20 cm (6–8 in) high, that is assigned to the daisy family. It branches near its base, and has few leaves along its stems. The lower leaves are set oppositely, inverted lance-shaped, relatively large at 3–7 cm long and ⅔–1¼ cm wide, and soon withering, while the higher ones are smaller and relatively narrower. In the axils of the leaves grow flower heads of 7–8 mm wide on stalks of up to 5 cm (2 in) long, topped with an involucre of about 5 mm (0.2 in) high and 4 mm (0.16 in) wide, consisting of eleven to thirteen bracts in two rows with bristles near the tip, eight to nine white or cream-coloured ligulate florets surrounding fourteen or fifteen deep purple disc florets. Flowers can be found in September and October. The species is an endemic species that can only be found in a small area along the west coast of the Western Cape province of South Africa.
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 heterophylla is a roughly hairy annual plant in the daisy family. It has alternate leaves of 1–5 cm long with an entire margin or few inconspicuous teeth. The flower heads are set individually at the tip of its stems, and contain a whorl of purplish blue ray florets around a center of blackish blue disk florets. Flower heads appear in winter and spring. It is called true-blue daisy in English and bloublomastertjie in Afrikaans. It is an endemic species that only occurs in the Western Cape province of South Africa.
Felicia cymbalariae, is a hairy perennial herbaceous plant of up to 30 cm (12 in) high in the daisy family. It has creeping branches that bend upwards, stalked leaves of up to 6 × 4½ cm (2.4 × 1.8 in) with few teeth or nearly entire. The flower heads are set individually on top of up to 8 cm (3 in) long stalks and contain about sixteen white ray florets of about 6 × 1½ mm around a center with many yellow or dark wine red disc florets. It can be found in the Western Cape province of South Africa. Flower heads can be found between September and June.
Felicia canaliculata is a grayish green shrublet in the daisy family that grows up to 40 cm (16 in) in height. It has narrow, awl-shaped leaves, relatively large flower heads with approximately a dozen light purple to white ray florets encircling many yellow disc florets. It can only be found in the Western Cape province of South Africa.
Felicia amoena is a variably hairy, sometimes glandular, biennial or perennial plant, of about 25 cm (10 in) high, that is assigned to the daisy family. It is somewhat woody at its base, roots at the nodes if these contact the soil, and has ascending branches. The leaves are oppositely arranged along the stems at and just above a branching fork, further up. The flower heads sit individually on up to 12 cm long stalks. They are 2–3 cm in diameter and consist of about twelve to twenty five heavenly blue ray florets that surround many yellow disc florets. Three subspecies have been recognised, that differ in width of the leaves and the involucral bracts, the size of the heads and number of ray florets and in having glandular hairs. These can be found in coastal sands and inland areas in the Western Cape and Eastern Cape provinces of South Africa. Flower heads can be found from June till October.
Felicia nordenstamii is a flowering shrub in the daisy family, Asteraceae. It is found only in South Africa where it grows on limestone hills close to the sea on the southern coast. Felicia nordenstamii is a many-branched shrub growing up to 30 cm (1 ft) tall. The lower parts of the stems are covered in grayish brown bark and the upper stem has many crowded, upwardly angled, alternate leaves with long hairs on the lower surfaces. Large flower heads form at the tips of the branches, each about 41⁄2 cm across, with about thirty purplish blue ray florets surrounding many yellow disc florets.
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.
Felicia annectens is an annual plant of up to about 25 cm (10 in) high, that is assigned to the daisy family. The lower leaves are opposite and the higher leaves alternate. The bloated involucre consists of very broad, hairless bracts. These protect up to ten, short, bluish ray florets that encircle yellow, partly sterile disc florets. The heads sit individually on top of up to 6 cm long stalks. The species was considered extinct after no observations were made after 1915, but was rediscovered in the 21st century. It occurs in the Western Cape province of South Africa.
