Hymenonema laconicum is a species of herbaceous perennial plant in the Asteraceae family. [1] 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. [2]
Hymenonema laconium is a perennial herbaceous plant of 20–70 cm high, with minute pale glandular hairs and longer hairs without glands. The number chromosomes is twenty (2n = 20). Both surfaces of the leaves are densely set with rigid hairs pressed to their surface. The leaves in the basal roset are 7–25 cm long and pinnately segmented, sometimes with teeth at the margin. The top segment is larger than the lateral segments, and 1½-3 cm wide, or sometimes a little as 1 cm. Between one and six smaller leaves are distanced along the stem, the lowest pinnately segmented, the higher increasingly simple, small and narrow. Each stem carries between one and three flowerheads. The involucre is 1½-2½ cm high and 1½-2¼ cm wide, with the individual bracts without hair, ovate to oblong-ovate in shape, with a rounded tip and an entire or dentate margin. The pits in the common base of the florets (called the receptacle) are each circled by a row of long hairs. The fruits (or cypselas) are 4–5 mm high and topped by the changed calyx called pappus. On the outer cypselas the pappus takes the shape of trifid scales, the middle branch of which is prolonged as a rigid hair. On the inner cypselas, there is a row of rigid hairs encircling a row of lanceolate scales that change at the tip into a rigid hair. [3]
The genus Hymenonema contains two species, H. graecum , that is known from the Cyclades, and H. laconicum. H. graecum has yellow ligulate florets with yellow anther tubes, which sit on 3½-5 mm long and ¾-1¾ mm thick, sparsely hairy cypselas, encircled by pappus that differs maximally 5 mm in length, and basal leaves with a narrow top segment of usually 3–10 mm. H. laconicum differs in having yolk yellow ligulate florets with a purple spot at the base and dark purple anther tubes, which sit on 4¾-6 mm long and 1½-2 mm wide densely hairy cypselas and the pappus differing 8–15 mm in length, and basal leaves with a wide top segment of 10–35 mm wide. [4]
Catananche graeca was described in 1753 by Carl Linnaeus, based on a specimen from the Cyclades. In 1817 Henri Cassini described Hymenonema tournefortii, which is now considered a synonym of Catananche graecaL.. In 1838 Augustin Pyramus de Candolle moved the species to Cassini's genus, recombining it with Linnaeus' epithet to Hymenonema graecum. Also in 1838, Jean Baptiste Bory de Saint-Vincent and Louis Athanase Chaubard in their Nouvelle Flore du Péloponèse et des Cyclades described Catananche graeca, but now based on a specimen from the Peloponnesos. Pierre Edmond Boissier and Theodor von Heldreich realised that the plants described by Linnaeus and by Bory and Chaubard, belonged to related but different species, therefore the last assigned name was no longer available, and hence invalid. They proposed a new name for it, Hymenonema laconium, which they published in 1875. [5] [6]
H. laconicum is limited to the central and south-eastern Peloponnesos, in particular the Mainalo, Parnon and Taygetos mountains and the surrounding lowlands. It grows at altitudes of 5–1300 m in shrubland on stony soils, field margins and meadows. [2]
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 daisy family. 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 Daisy family, 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 known as سكوليمس (skwlyms) in Arab, scolyme in French, and is sometimes called golden thistle or oyster thistle in English.
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, 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.
Felicia amelloides, the blue daisy bush or blue felicia, is a hairy, soft, usually perennial, evergreen plant, in the daisy family. 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.
Polyarrhena is a genus of low, branching shrublets that is assigned to the daisy family. Its stems are alternately and densely set with entire or somewhat toothed leaves. 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 three whorls of bracts. In Polyarrhena, the centre of the head is taken by yellow disc florets, and is surrounded by one single whorl of white ligulate florets that have a pinkish-purple wash on the underside. These florets sit on a common base and are not individually subtended by a bract. The species occur in the Cape Floristic Region. Polyarrhena reflexa has long been cultivated as an ornamental and is often known under its synonym Aster reflexum.
Hymenonema is a genus of flowering plants in the dandelion family endemic to Greece. On each of the single or few stems, the species have one to three flowerheads consisting of yellow or yolk yellow ligulate florets, scaly pappus, greyish, pinnately segmented leaves in a basal rosette, and few smaller leaves on the 20–70 cm high stems. It contains two species: Hymenonema graecum, that is known from the Cyclades, and Hymenonema laconicum, which occurs in the central and south-eastern Peloponnesos.
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.
The Stifftioideae are a subfamily of the Asteraceae, or sunflower family, of flowering plants. It comprises a single tribe, Stifftieae, of ten genera.
Hymenonema graecum is a perennial herbaceous plant of 20–70 cm, that rests with its buds at or just under the surface of the soil. The Greek vernacular name is Αδραλίδα (Adralida), meaning "handsome Lida". The leaves are pinnate, and may be up to 1 cm wide. The ligulate flowers are yellow. The species is an endemic of Greece.
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, assigned to the daisy family, 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.
Famatinanthus is a genus in the family Asteraceae that was described in 2014 and has been assigned to its own tribe Famatinantheae and subfamily Famatinanthoideae. It contains only one known species, F. decussatus, a small shrub of ½—1¾ m high that is an endemic of the Andes of north-western Argentina, with small, entire, oppositely set leaves and flowerheads containing about ten cream-colored, ray and disk florets, with backward coiled lobes. It is locally known as sacansa. For more than 100 years, the species was known to science only from the type collection. It was described in 1885 and originally assigned to the genus Aphyllocladus.
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.
Oedera capensis is a prickly shrublet belonging to the daisy family. It has stems that branch only at the foot and are densely set over their entire length with narrowly triangular leathery leaves with a sharp tip at approximately right angles to the stem. At their tip are what at first sight appears to be a single flowerhead with yellow ray florets and yellow disc florets. In fact, these are mostly nine densely cropped heads, as is suggested by the nine domes of the "disc" of the composite head, the untidy arrangement of the ray florets, and becomes very clear when cutting through the composite head. It is an endemic of the south of the Western Cape province in South Africa.
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.
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 macrorrhiza is a small, evergreen shrub in the daisy family. This species grows in the Karoo region of South Africa. It is called Aspoestertjie in Afrikaans.
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, seldomly 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.
