Galactites tomentosus, the purple milk thistle, is a biennial herbaceous plant belonging to the genus Galactites of the Asteraceae family. [2]
Galactites tomentosus is a hemicryptophyte plant up to 1 metre (3 ft 3 in) tall. The stem is erect and pubescent, branched at the top. The leaves are green, long and pinnatisect, lanceolate, mottled with white markings, while the underside is whitish and covered with matted woolly hairs. The margins of the leaves bear strong thorns. [2]
The flower heads are quite large – about 3 centimetres (1.2 in) in diameter. The involucre of the flower head is covered by hairy scales ending with a single grooved thorn. The central flowers are hermaphrodite and are pollinated by insects, while external flowers are sterile; their color varies from white or pink to lilac-purple. [2]
The flowering period extends from April through July [2] and the seeds ripen from August through September[ citation needed ]. The fruits are achenes with whitish hairy appendages (pappus). [2]
The genus name derives from the Greek γάλα (= "milk"), referring to the dense white hairs covering the stems and leaves of this species, the species name tomentosus means hairy in Latin. [2]
This plant is distributed around the Mediterranean Basin, from Greece to the Iberian Peninsula, Morocco and Madeira and Canary Islands. [3] It has been introduced to the Azores. [4]
This plant prefers sunny places and usually grows on the uncultivated or barren grounds, waste places, well-drained soils, pastures and roadsides. [3]
Echinacea is a genus of herbaceous flowering plants in the daisy family. It has ten species, which are commonly called coneflowers. They are found only in eastern and central North America, where they grow in moist to dry prairies and open wooded areas. They have large, showy heads of composite flowers, blooming in summer. The generic name is derived from the Greek word ἐχῖνος, meaning "sea urchin", due to the spiny central disk. These flowering plants and their parts have different uses. Some species are cultivated in gardens for their showy flowers. Two of the species, E. tennesseensis and E. laevigata, are listed in the United States as endangered species.
Gundelia is a low to high (20–100 cm) thistle-like perennial herbaceous plant with latex, spiny compound inflorescences, reminiscent of teasles and eryngos, that contain cream, yellow, greenish, pink, purple or redish-purple disk florets. It is assigned to the family Asteraceae. Flowers can be found from February to May. The stems of this plant dry-out when the seeds are ripe and break free from the underground root, and are then blown away like a tumbleweed, thus spreading the seeds effectively over large areas with little standing vegetation. This plant is native to the eastern Mediterranean and the Middle-East. Opinions differ about the number of species in Gundelia. Sometimes the genus is regarded monotypic, Gundelia tournefortii being a species with a large variability, but other authors distinguish up to nine species, differing in floret color and pubescence. Young stems are cooked and eaten in the Middle-East and are said to taste like a combination of artichoke and asparagus. The plant also contains compounds that have been demonstrated to be effective against a range of ailments. A large quantity of pollen assigned to Gundelia has been found on the Shroud of Turin, which may suggest that the crown of thorns was made from Gundelia, but this finding has been contested.
Scolymus is a genus of annual, biennial or perennial, herbaceous plants that is assigned to the family Asteraceae, and can be found in Macaronesia, around the Mediterranean, and in the Middle East. All species are spiny, thistle-like in appearance, with flowerheads that consist of yellow ligulate florets, and canals that contain latex. It is sometimes called golden thistle or oyster thistle, and is known as سكوليمس (skwlyms) in Arabic and scolyme in French.
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.
Catananche caerulea, or Cupid's dart, is a greyish green perennial herbaceous plant with a basal leaf rosette and conspicuous blue-purple or sometimes white flowerheads, belonging to the daisy family. It is a popular garden plant and is often used in dried flower arrangements.
Banksia lanata is a species of shrub that is endemic to a restricted area of Western Australia. It has linear leaves, pale cream-coloured flowers in a head with whitish bracts at the base and later up to fifty elliptical follicles in each head.
Cirsium eriophorum, the woolly thistle, is a herbaceous biennial species of flowering plant in the genus Cirsium of the family Asteraceae. It is widespread across much of Europe. It is a large biennial plant with sharp spines on the tips of the leaves, and long, woolly hairs on much of the foliage. The flower heads are large and nearly spherical, with spines on the outside and many purple disc florets but no ray florets.
Adenocaulon bicolor, the American trailplant, trailplant, pathfinder, or silver-green, is a flowering plant in the family Asteraceae, native to North America. It is found in southern Canada and across the northern and western United States. It is the only species of Adenocaulon native to the United States or Canada. The genus name Adenocaulon is derived from Greek, and refers to the glandular stem. The English name "Pathfinder" was given to this species, because if you walk through a patch of its leaves you will find the path you made through them, with some of the white undersides of the leaves having been exposed, by them having been twisted. Over time, the plant will turn its leaves back with the green side up, and the white side down.
Ozothamnus ferrugineus, commonly known as tree everlasting, is a member of the genus Ozothamnus, of the Asteraceae family – one of the largest families of flowering plants in Australia. Native to the Australian states of New South Wales, Victoria, South Australia, and Tasmania, it forms an erect shrub or small tree between 2 and 3 metres in height.
Galactites is a genus of flowering plants in the family Asteraceae. The name is derived from the Greek γάλα. The best known species is Galactites tomentosus.
Brintonia is a monotypic genus of flowering plants in the sunflower family, containing the single species Brintonia discoidea, named for Jeremiah Bernard Brinton. It is known commonly as the rayless mock goldenrod. It is native to the southeastern United States, where it is distributed in Alabama, Florida, Georgia, Louisiana, and Mississippi.
Ipomoea lacunosa, the whitestar, white morning-glory or pitted morning-glory, is a species that belongs to the genus Ipomoea. In this genus most members are commonly referred to as "morning glories". The name for the genus, Ipomoea, has root in the Greek words ips and homoios, which translates to worm-like. This is a reference to the plant's vine-like growth. Lacunosa comes from a Latin word meaning air spaces, correlating with the venation of the leaves. Ipomoea lacunosa is native to the United States and grows annually. The flowers of this species are usually white and smaller than most other morning glories.
Cirsium altissimum is a North American species of plants in the tribe Cardueae within the family Asteraceae. Common names are tall thistle or roadside thistle. The species is native to the eastern and Central United States.

Hymenonema laconicum is a species of herbaceous perennial plant in the Asteraceae family. It is small to average height, with a rosette of greyish pinnately segmented leaves, and little branching solid stems carrying one to three heads of orange or yolk yellow ray-flowers, with a purple anther tube, and scaly pappus. The species is an endemic of the central and south-eastern Peloponnesos, and flowers in May and June.
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.
Mitrephora tomentosa is a species of plant in the family Annonaceae. It is native to Bangladesh, Cambodia, Laos, Myanmar, Thailand, and Vietnam. Joseph Hooker and Thomas Thomson, the British botanists who first formally described the species, named it after the dense covering of hair on its young branches, leaves and flowers.
