Townsendia florifera is a low growing herbaceous flowering plant in the family Asteraceae, with the common name showy Townsendia. [1] [2] [3]
Townsendia florifera is an annual, biennial or perennial herb from a persistent base. The green basal leaves are spatulate to spatulate-obovate, 2-6 cm long and 3-11 mm wide, with cauline leaves similar or reduced. Leaves, stems, and floral bracts are sparsely to moderately-densely covered with short white hairs. The showy composite flowers are usually solitary on each short stem, with somewhat imbricate green bracts (overlapping segments) that are narrow and pointed with fringed margins. The 10 to 20 ray florets are light pink to nearly white and 7-12 mm long. Disk florets are numerous and yellow. [3]
Townsendia florifera grows in dry open areas in the northwestern to west-central United States, often with sagebrush in gravelly or sandy areas. The range is central Washington and Oregon, southern Idaho, eastern Nevada, and western Utah, Montana, and Wyoming. [2]
Ionactis, common name stiff-leaved asters or ankle-asters, is a small genus of plants belonging to the family Asteraceae. These aster-like plants are endemic to North America. One species is widespread across much of the eastern half of the continent, while two others are rare endemics with very restricted ranges.
Scolymus maculatus is a spiny annual plant in the family Asteraceae, native to the Mediterranean region in southern Europe, southwest Asia, and northern Africa, and also the Canary Islands. It has pinnately incised prickly leaves and prickly wings along the stems, both with a white marginal vein. The yellow flowerheads stand solitary or with a few together at the tip to the stems, and subtended by more than five leaflike bracts. The plant is known as scolyme taché in French, cardogna macchiata in Italian, cardo borriquero in Spanish, and escólimo-malhado in Portuguese, חוח עקוד in Hebrew and سنارية حولية in Arabic. In English it is called spotted golden thistle or spotted oyster thistle.
Tripleurospermum inodorum, common names scentless false mayweed, scentless mayweed, scentless chamomile, and Baldr's brow, is the type species of Tripleurospermum. This plant is native to Eurasia and North Africa, and introduced to North America, where it is commonly found in fields, fallow land and gardens.
Eurybia is a genus of plants in the family Asteraceae that were previously included in the genus Aster. Most species are native to North America, although one is also present in northern Eurasia. There are 23 species in the genus, including 1 natural hybrid. The name was first applied by Alexandre de Cassini in 1820. The name is derived from Ancient Greek εὐρύς (eurús), meaning "wide", and βαιός (baiós), meaning "few", perhaps in reference to the small number of relatively wide ray florets.
Felicia amelloides, the blue daisy bush or blue felicia, is a hairy, soft, usually perennial, evergreen plant, in the family Asteraceae. It can be found along the southern coast of South Africa. It grows as ground cover and produces many very regular branches. It mostly grows to about 50 cm (1.6 ft) high, rarely to 1 m. The leaves are oppositely arranged along the stems, dark green in colour and elliptic in shape. The flower heads sit individually on up to 18 cm (7 in) long, green to dark reddish stalks. They consist of about twelve heavenly blue ray florets that surround many yellow disc florets, together measuring about 3 cm across. It is also cultivated as an ornamental, and was introduced in Europe in the middle of the 18th century.
Felicia filifolia is a Southern African member of the family Asteraceae. It is a hardy, sprawling shrub growing to about 1 metre tall. Leaves are narrow and clustered along the twigs. When blooming it is densely covered in flowerheads with ray florets that are pink-mauve to white and disc florets that are yellow. In the wild, flowers can be found August to December.
Warionia is a genus in the tribe Cichorieae within the family Asteraceae. 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.
Nestotus stenophyllus is a species of flowering plant in the family Asteraceae known by the common name narrowleaf mock goldenweed. It was previously known as Stenotus stenophyllus. It is native to the western United States, especially the inland Pacific Northwest and northern Great Basin, where it grows in sagebrush habitat usually in rocky soil.
Cyclachaena xanthiifolia, known as giant sumpweed, or rag sumpweed is a North American plant species in the sunflower family, Asteraceae. It is the only species in the genus Cyclachaena. Giant sumpweed is believed to be native to the Great Plains but is now found across much of southern Canada and the contiguous United States, though rarely in the Southeast.
Erigeron poliospermus is a species of flowering plant in the family Asteraceae known by the common names gray-seeded fleabane, purple cushion fleabane, and hairy-seed fleabane. Native to western North America, it is mainly found to the east of the Cascade Range in Washington, Oregon, and Idaho.
Scolymus grandiflorus is a spiny annual or biennial plant in the family Asteraceae, native to the Mediterranean region. With up to 75 cm high stems, it is the smallest of the species of Scolymus. Its stems are lined with uninterrupted spiny wings. It also has the largest flowerheads in the genus, of approximately 5 cm wide. It has yellow, sometimes yolk-yellow ligulate florets. Its vernacular name in Maltese is xewk isfar kbir, meaning "large yellow fin", cardogna maggiore in Italian, scoddi on Sicily, and scolyme à grandes fleurs in French.
Catananche lutea, is a woolly annual plant, in the family Asteraceae, with most leaves in a basal rosette, and some smaller leaves on the stems at the base of the branches. Seated horizontal flowerheads develop early on under the rosette leaves. Later, not or sparingly branching erect stems grow to 8–40 cm high, carrying solitary flowerheads at their tips with a papery involucre whitish to beige, reaching beyond the yellow ligulate florets. Flowers are present between April and June. This plant is unique for the five different types of seed it develops, few larger seeds from the basal flowerheads, which remain in the soil, and smaller seeds from the flowerheads above ground that may be spread by the wind or remain in the flowerhead when it breaks from the dead plant. This phenomenon is known as amphicarpy. The seeds germinate immediately, but in one type, germination is postponed. It naturally occurs around the Mediterranean. Sources in English sometimes refer to this species as yellow succory.
Felicia echinata, commonly known as the dune daisy or prickly felicia, is a species of shrub native to South Africa belonging to the daisy family. It grows to 1 m (3.3 ft) high and bears blue-purple flower heads with yellow central discs. In the wild, it flowers April to October.
Felicia josephinae is a roughly hairy annual herbaceous plant of 15–20 cm (6–8 in) high, that is assigned to the family Asteraceae. 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 (2.0 in) long, topped with an involucre of about 5 mm (0.20 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.
Felicia canaliculata is a grayish green shrublet in the family Asteraceae 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 nordenstamii is a flowering shrub in the 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.
Felicia westae is a sparsely branched shrub growing up to 40 cm tall, that is assigned to the family Asteraceae. The lower parts of the stems have lost their leaves and the upper part has many crowded, upwardly angled and curved, alternate leaves pressed against the stem, with the edges curled inward. The flower heads form at the tips of the branches, each about 31⁄3 cm across, with about twenty purplish blue ray florets surrounding many yellow disc florets. It is only known from a small area in the Eastern Cape province of South Africa.
