Eryngium is a genus of flowering plants in the family Apiaceae. There are about 250 species. [1] The genus has a cosmopolitan distribution, with centres of diversity in the western Mediterranean, South America and Mexico. [2] Common names include eryngo and sea holly (though not to be confused with true hollies, of the genus Ilex ).
These are annual and perennial herbs with hairless and usually spiny leaves. The dome-shaped umbels of steely blue or white flowers have whorls of spiny basal bracts. European and Asian species tend to be native to dry, rocky and coastal areas, and the American species are native to often damp grasslands. [3]
In the language of flowers, they represent admiration. [4]
The genus name Eryngium was established by Linnaeus in 1753 where he mentioned eight species, including two from America (E. aquaticum, E. foetidum). Linnaeus, in Genera Plantarum (1754), cited his source of the name Eryngium as being from Joseph Tournefort’s Institutiones rei herbariae (1700). The name itself has an Ancient Greek origin as eryggion (ερψγγιον). [5]
Prior to the nomenclatural establishment of Eryngium by Linnaeus, plants that can be recognised as belonging to the genus were mentioned by Theophrastus (371–287BC), Pedanius Dioscorides (40–90AD), Otto Brunfels (1532) and Leonhart Fuchs (1543). Early mentions of American species were made by Francisco Hernández de Toledo (1651) and Leonard Plukenet (1692). [5]
After Linnaeus, a major treatment of the genus was made by Jean-Baptiste Lamarck (1798) who mentioned 25 species, and Antonio José Cavanilles (1800, 1801) who described at least seven species, six of which were from America. The first monograph of the genus was by François-Étienne de La Roche (1808), which covers 50 species. In the 19th century further European and Asian species were described by Pierre Edmond Boissier and Augustin Pyramus de Candolle, and American species by Adelbert von Chamisso, Joseph Decaisne, William Jackson Hooker, August Grisebach, Willis Linn Jepson and Rodolfo Amando Philippi. In 1913 Karl F.A.H. Wolff published a major revision of the genus, discussing 196 species which he allocated to 34 sections while also recognising a division between Old World (Europe and Asia) and New World (America and Australia) species. The understanding of American species was further enhanced by Mildred E. Mathias (1906–1995) and Lincoln Constance (1909–2001) who published a synopsis of North American species (Mathias & Constance 1941) and described a total of 18 species from North and South America. [5]
More recently, Arno Wörz has made a major contribution to the understanding of the genus with his revision of European, Asian and African species (Wörz 2011 [5] ) and his checklist of all species (Wörz 1999 [6] ).
It is likely that the genus originated in Eurasia, with a radiation from west to east in subgenus Eryngium, and the western Mediterranean being a primary centre of diversity. The American species are probably derived from a more recent intensive evolution and radiation, possibly from a single trans-Atlantic dispersal and subsequent landfall in southeastern South America where there is a primary diversity centre in southern Brazil and a younger secondary one in Mexico. It is likely that the sword-leaved structure seen in many American species occurred only once in the evolution of the genus. The palmate leaf patterns seen in Eurasian species do not occur in any American species. [2]
Wörz (2011 [5] ) divided the genus into six subgenera, with one subgenus divided into 10 sections:
Eryngos are grown as ornamental plants in gardens. The most widely grown species are E. agavifolium, E. alpinum, E. bourgatii, E. giganteum, E. pandanifolium, E. planum, E. variifolium and E. yuccifolium. [3] Two hybrids have also been selected for garden use, one being E. × olivierianum [9] (syn. E. x zabelii), of which there are several cultivars such as ‘Big Blue’, [10] and the other is E. × tripartitum. [11] The species with the most cultivars is E. planum. [3] Overall, around 250 cultivars have been named in the genus. [12] Some species and cultivars have gained the Royal Horticultural Society's Award of Garden Merit.
Many species of Eryngium have been used as medicine and food. Eryngium campestre is used as a folk medicine in Turkey. In Iran, Eryngium (Boghnagh فارسی- بوقناق) is used as herbal tea to lower blood sugar. Eryngium creticum is a herbal remedy for scorpion stings in Jordan. Eryngium elegans is used in Argentina and Eryngium foetidum in Latin America and South-East Asia. Native American peoples used many species for varied purposes. Cultures worldwide have used Eryngium extracts as anti-inflammatory agents. Eryngium yields an essential oil and contains many kinds of terpenoids, saponins, flavonoids, coumarins, and steroids. [13]
The roots have been used as vegetables or sweetmeats, particularly Eryngium maritimum. Young shoots and leaves are sometimes used as vegetables like asparagus. Eryngium foetidum is used as a culinary herb in tropical parts of the Americas and Asia. It tastes similar to coriander or cilantro, and is sometimes mistaken for it. It may be called spiny coriander or culantro, or by its Vietnamese name of ngo gai. [14]
Apiaceae or Umbelliferae is a family of mostly aromatic flowering plants named after the type genus Apium, and commonly known as the celery, carrot or parsley family, or simply as umbellifers. It is the 16th-largest family of flowering plants, with more than 3,800 species in about 446 genera, including such well-known, and economically important plants as ajwain, angelica, anise, asafoetida, caraway, carrot, celery, chervil, coriander, cumin, dill, fennel, lovage, cow parsley, parsley, parsnip and sea holly, as well as silphium, a plant whose exact identity is unclear and may be extinct.
Eryngium maritimum, the sea holly or sea eryngo, or sea eryngium, is a perennial species of flowering plant in the family Apiaceae and native to most European coastlines. It resembles a thistle in appearance because of its burr-shaped inflorescences. Despite its common name, it is not a true holly but an umbellifer.
Berberis, commonly known as barberry, is a large genus of deciduous and evergreen shrubs from 1–5 m (3.3–16.4 ft) tall, found throughout temperate and subtropical regions of the world. Species diversity is greatest in South America and Asia; Europe, Africa and North America have native species as well. The best-known Berberis species is the European barberry, Berberis vulgaris, which is common in Europe, North Africa, the Middle East, and central Asia, and has been widely introduced in North America. Many of the species have spines on the shoots and all along the margins of the leaves.
Eryngium alpinum, the alpine sea holly, alpine eryngo or queen of the Alps, is a herbaceous perennial plant in the family Apiaceae.
Ilex aquifolium, the holly, common holly, English holly, European holly, or occasionally Christmas holly, is a species of flowering plant in the family Aquifoliaceae, native to western and southern Europe, northwest Africa, and southwest Asia. It is regarded as the type species of the genus Ilex, which by association is also called "holly". It is an evergreen tree or shrub found, for example, in shady areas of forests of oak and in beech hedges. In the British Isles it is one of very few native hardwood evergreen trees. It has a great capacity to adapt to different conditions and is a pioneer species that repopulates the margins of forests or clearcuts.
Eryngium yuccifolium, known as rattlesnake master, button eryngo, and button snake-root, is a perennial herb of the parsley family native to the tallgrass prairies of central and eastern North America. It grows from Minnesota east to Ohio and south to Texas and Florida, including a few spots in Connecticut, New Jersey, Maryland, and Delaware.
Eryngium giganteum, with the common name Miss Willmott's ghost, is a species of flowering plant in the family Apiaceae.
Eryngium castrense is a species of flowering plant in the family Apiaceae known by the common name Great Valley eryngo, or Great Valley button celery. This plant is endemic to California, where it grows in wet areas such as vernal pools and ponds in the central part of the state. This is a heavily branched, spiny perennial herb reaching maximum heights of around half a meter. It produces light green to grayish green hairless stems with occasional lobed, oval-shaped leaves. At the tops of the stems are flower heads one to one and a half centimeters wide and rounded or egg-shaped. At the base of each head is an array of 7 to 9 spiny, pointed bracts up to three centimeters long, and sometimes a few smaller bractlets above. The rounded flower head contains many small white to light purple flowers.
Selinum carvifolia is a flowering plant of the genus Selinum in the family Apiaceae. The specific name carvifolia signifies 'having leaves resembling those of Caraway'. It is a plant of fens and damp meadows, growing in most of Europe, with the exception of much of the Mediterranean region, eastwards to Central Asia. Its common name in English is Cambridge milk parsley, because it is confined, in the UK, to the county of Cambridgeshire and closely resembles milk parsley, an umbellifer of another genus, but found in similar habitats. The two plants are not only similar in appearance, but also grow in similar moist habitats, although they may be told apart in the following manner: P. palustre has hollow, often purplish stems, pinnatifid leaf lobes and deflexed bracteoles; while S. carvifolia has solid, greenish stems, entire or sometimes lobed leaf-lobes and erecto-patent bracteoles. Also, when the two plants are in fruit, another difference becomes apparent: the three dorsal ridges on the fruit of S. carvifolia are winged, while those on the fruit of P. palustre are not. Yet a further difference lies in the respective leaflets of the plants : those of Peucedanum palustre are blunt and pale at the tip, while those of Selinum carvifolia are sharply pointed and of a darker green. S. carvifolia used also to occur in the English counties of Nottinghamshire and Lincolnshire but is now extinct in both. Growing in only three small Cambridgeshire fens, it is one of England's rarest umbellifers. It is naturalized in the United States, where it is known by the common name little-leaf angelica.
Eryngium racemosum is a rare species of flowering plant in the family Apiaceae known by the common name delta eryngo, or delta button celery.
Eryngium spinosepalum, known by the common names spinysepal eryngo and spiny-sepaled button celery, is an uncommon species of flowering plant in the family Apiaceae.
Eryngium foetidum is a tropical perennial herb in the family Apiaceae. Common names include culantro (Panama), cimarrón,recao, chardon béni (France), Mexican coriander, samat, bandhaniya, long coriander, Burmese coriander, sawtooth coriander, and ngò gai (Vietnam). It is native to Mexico, the Caribbean, and Central and South America, but is cultivated worldwide, mostly in the tropics as a perennial, but sometimes in temperate climates as an annual.
Eryngium cuneifolium is a rare species of flowering plant in the carrot family known by the common names wedgeleaf eryngo, wedge-leaved button-snakeroot, and simply snakeroot. It is endemic to the state of Florida in the United States where it is known only from Highlands County. It is one of many rare species that can be found only on the Lake Wales Ridge, an area of high endemism. It was federally listed as an endangered species of the United States in 1987.
Eryngium planum, the blue eryngo or flat sea holly, is a species of flowering plant in the family Apiaceae, native to the area that includes central and southeastern Europe and central Asia. It is an herbaceous perennial thistle growing to 50 cm (20 in) with branched silvery-blue stems, and numerous small blue conical flowerheads surrounded by spiky bracts in summer.
Eryngium aquaticum is a species of flowering plant in the family Apiaceae known by the common name rattlesnakemaster, marsh rattlesnake master, corn-snakeroot, bitter snakeroot, and marsh eryngo. This plant is native to eastern North America.
Eryngium bourgatii, the Mediterranean sea holly, is a species of flowering plant in the family Apiaceae native to Andorra, France and Spain, as well as parts of the Levant, Morocco and Turkey. It is an herbaceous perennial, growing to 15–45 cm (6–18 in) tall. The spherical, blue flowerheads have typically spiny bracts.
Eryngium creticum, or the field eryngo, is a species of flowering plant in the family Apiaceae native to Greece, Israel, Jordan, Lebanon, Palestine, and Syria. It is known in Lebanon and Palestine as قرصعنة and in Israel as חרחבינה מכחילה.
Eryngium baldwinii is a biennial aromatic herb in the Eryngium genus. Its common name is Baldwin's eryngo. It can grow to become a spread out groundcover with hazy appearing light blue flowers. It is named for William Baldwin.
Eryngium ebracteatum Lam., the burnet-flowered sea holly, is a herbaceous perennial native to damp grasslands in South America. The species is occasionally cultivated as an ornamental plant.
