Plants named in 1756

The shallot is a cultivar group of the onion. Until 2010, the (French red) shallot was classified as a separate species, Allium ascalonicum. The taxon was synonymized with Allium cepa (the common onion) in 2010, as the difference was too small to justify a separate species. As part of the onion genus Allium, its close relatives include garlic, scallions, leeks, chives, and the Chinese onion.

Abies alba, the European silver fir or silver fir, is a fir native to the mountains of Europe, from the Pyrenees north to Normandy, east to the Alps and the Carpathians, Slovakia, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia, and south to Italy, Bulgaria, Kosovo, Albania and northern Greece.

Rhus typhina, the staghorn sumac, is a species of flowering plant in the family Anacardiaceae, native to eastern North America. It is primarily found in southeastern Canada, the northeastern and midwestern United States, and the Appalachian Mountains, but it is widely cultivated as an ornamental throughout the temperate world. It is an invasive species in some parts of the world.

Centaurium (centaury) is a genus of 20 species in the gentian family (Gentianaceae), tribe Chironieae, subtribe Chironiinae. The genus was named after the centaur Chiron, famed in Greek mythology for his skill in medicinal herbs. It is distributed across Europe and Asia. Until 2004, Centaurium was given a much wider circumscription, comprising about 50 species ranging across Europe, Asia, the Americas, Australasia, and the Pacific. However this circumscription was polyphyletic, so in 2004 the genus was split into four, being Centaurium sensu stricto, Zeltnera, Gyrandra, and Schenkia.

Rhinanthus minor, known as yellow rattle, is a herbaceous wildflower in the genus Rhinanthus in the broomrape family. It has circumpolar distribution in Europe, Russia, western Asia, and northern North America.

The preferred habitat of Rhinanthus minor is dry fields or meadows; it tolerates a wide range of soil types. It flowers in the summer between May and September. It is hemiparasitic, notably on Poaceae

Petroselinum is a genus of two parsley species of flowering plants in the family Apiaceae, native to western and southern Europe and northern Africa. Plants of this genus are bright green, hairless, biennial and herbaceous; they are rarely annual plants. In the first year, they form a rosette of pinnate to tripinnate leaves and a tap root used as a food store over the winter. In the second year they grow a flowering stem up to 1 m tall with sparser leaves and umbels of white or pinkish to yellowish-green flowers.

Lactuca serriola, also called prickly lettuce, milk thistle (not to be confused with Silybum marianum, also called milk thistle), compass plant, and scarole, is an annual or biennial plant in the tribe Cichorieae within the family Asteraceae. It has a slightly fetid odor and is commonly considered a weed of orchards, roadsides and field crops. It is the closest wild relative of cultivated lettuce (Lactuca sativa L.). Lactuca serriola is native to Eurasia and north Africa, and has become naturalized elsewhere.

Cladium (fen-sedge, sawgrass or twig-sedge) is a genus of large sedges, with a nearly worldwide distribution in tropical and temperate regions. These are plants characterized by long, narrow (grass-like) leaves having sharp, often serrated (sawtooth-like) margins, and flowering stems 1–3 m tall bearing a much-branched inflorescence. Like many plants found in wet habitats, it has deeply buried rhizomes that can produce tall shoots with dense canopies. Cladium mariscus subsp. jamaicense, or saw-grass, is common in marshes and savannas throughout the tropical Americas. One typical and well-known

Parietaria judaica, spreading pellitory, is a species of herbaceous perennial flowering plant in the family Urticaceae. It is native to the eastern Mediterranean and Middle East, and is widely established worldwide as an urban weed. Its pollen is a significant cause of asthma and other allergies in warmer countries, but it is also valued as a contributor to biodiversity in polluted cities and it has been used as a medicinal herb.

Cymbalaria is a genus of about 10 species of herbaceous perennial plants previously placed in the family Scrophulariaceae, but recently shown by genetic research to be in the much enlarged family Plantaginaceae. The genus is native to southern Europe. It is closely related to the genera Linaria and Antirrhinum, differing in having creeping growth and flowers borne singly rather than in dense erect spikes. The common name toadflax is shared with Linaria and other related genera. The scientific name means "resembling a cymbal" for the somewhat rounded leaves. By far the best known species is

Cedrela is a genus of several species in the mahogany family, Meliaceae. They are evergreen or dry-season deciduous trees with pinnate leaves, native to the tropical and subtropical New World, from southern Mexico south to northern Argentina. On 28 October 2022, all Neo-tropic Cedrela species were added to the list of species requiring international protections, in CITES Appendix II.

Erythroxylum is a genus of tropical flowering plants in the family Erythroxylaceae. Many of the approximately 200 species contain the tropane alkaloid cocaine, and two of the species within this genus, Erythroxylum coca and Erythroxylum novogranatense, both native to South America, are the main commercial source of cocaine and of the mild stimulant coca tea. Another species, Erythroxylum vaccinifolium (also known as catuaba) is used as an aphrodisiac in Brazilian drinks and herbal medicine. Erythroxylum australe was traditionally used by Aboriginal Australians for rites and other practices.

Solanum aethiopicum, the bitter tomato, Ethiopian eggplant, or nakati, is a fruiting plant of the genus Solanum mainly found in Asia and Tropical Africa. It is also known as Ethiopian nightshade, garden eggs, pumpkin-on-a-stick, and mock tomato. It is a popular vegetable in north-east India, and is known as khamen akhaba in Manipuri and samṭawk in Mizo. They are called Titay bii or simply bii in Darjeeling, Sikkim and Nepal, and are relished with meat, particularly pork. These names are a result of its varied morphology, with ripe fruit often looking like a cross between an eggplant and a

Pilosella is a genus of flowering plants in the family Asteraceae. It includes approximately 250 species native to temperate Eurasia and northwestern Africa. Some sources include it within the genus Hieracium.

Coccoloba is a genus of 177 species of flowering plants in the family Polygonaceae, which is native to the Neotropics. There is no overall English name for the genus, although many of the individual species have widely used common names.

This plant is native to southern Europe, most of Africa and Asia, and Australia, and it is naturalized in other areas of the world, including large parts of the Americas. Cyperus difformis is a plant of aquatic and moist habitats. It is a weed of rice fields, but not generally a troublesome one. This is an annual herb with one to many thin, soft erect stems reaching over 30 centimeters in maximum height. There are usually a few long, wispy leaves

Salsola tragus, often known by its synonym Kali tragus, is a species of flowering plant in the family Amaranthaceae. It is known by various common names such as prickly Russian thistle, windwitch, or common saltwort. It is widely known simply as tumbleweed because, in many regions of the United States, it is the most common and most conspicuous plant species that produces tumbleweeds. Informally, it may be known as Kali or Salsola: the latter being its restored genus, containing 54 other species, into which the obsolete genus Kali has been subsumed.

Cuphea is a genus containing about 260 species of annual and perennial flowering plants native to warm temperate to tropical regions of the Americas. The species range from low-growing herbaceous plants to semi-woody shrubs up to 2 m (6 ft 7 in) tall. Commonly they are known as cupheas, or, in the case of some species, as cigar plants. The generic name is derived from the Greek word κυφος (kyphos), meaning "bent," "curved," or "humped."

Sechium was a genus of plants now subsumed into the genus Sicyos: also placed in the tribe Sicyoeae of the gourd family, Cucurbitaceae. Its best known member was the edible and widely cultivated chayote (now Sicyos edulis).

Reseda odorata is a species of flowering plant in the reseda family known by many common names, including garden mignonette and common mignonette. It is probably native to the Mediterranean Basin, but it can sometimes be found growing in the wild as an introduced species in many parts of the world. These introductions are often garden escapees; the plant has long been kept as an ornamental plant for its fragrant flowers, the essential oil of which has been used in perfumes. This is an annual herb, producing branching erect stems to 80 centimeters in maximum height. The inflorescence is a

Ornithogalum narbonense, common names Narbonne star-of-Bethlehem, pyramidal star-of-Bethlehem and southern star-of-Bethlehem, is a herbaceous perennial flowering plant with underground bulbs, belonging to the genus Ornithogalum of the family Asparagaceae. The Latin name Ornithogalum of the genus, meaning "bird's milk", derives from the Greek, while the species name narbonense refers to the French town of Narbonne.

They are halophytic (salt tolerant) plants, native to the coastal salt marshes of warm temperate and tropical America (B. maritima) and tropical Australasia (B. argillicola).

Sisymbrium orientale is a species of flowering plant in the family Brassicaceae known by the common names Indian hedgemustard and eastern rocket. It is native to Europe, Asia, and North Africa, and it can be found throughout much of the temperate world as an introduced species and in some areas a common roadside weed. It is an annual herb producing a hairy, branching stem up to about 30 centimeters tall. The basal leaves are divided into deep lobes or toothed leaflets. Leaves higher on the stem have lance-shaped blades with small separate lobes near the base. The top of the stem is occupied

Hordeum bulbosum, bulbous barley, is a species of barley native to southern Europe, northern Africa, the Middle East and as far east as Afghanistan, with a few naturalized populations in North America, South America and Australia. Since 1970 it has been used in the Hordeum bulbosum Method (or Technique) to produce doubled haploid (DH) wheat and barley plants by crossing it with T. aestivum or H. vulgare, followed by the elimination of the H. bulbosum chromosomes from the offspring. These DH plants are important in breeding new varieties of wheat and barley, and in scientific studies. H.
