Plants named in 1775

Ipomoea aquatica, commonly known as water spinach or kangkung, is a semi-aquatic, tropical plant grown as a vegetable for its tender shoots. I. aquatica is generally believed to have been first domesticated in Southeast Asia. It is widely cultivated in Southeast Asia, East Asia, and South Asia. It grows abundantly near waterways and requires little to no care.

Crataegus monogyna, known as common hawthorn, whitethorn, one-seed hawthorn, or single-seeded hawthorn, is a species of flowering plant in the rose family, Rosaceae. It grows to about 10 metres (33 feet) tall, producing hermaphrodite flowers in late spring. The berry-like pomes (known as haws) contain a stone-encased seed. The plant is native to Europe, but has been introduced in many other parts of the world. The pome flesh is of little culinary interest due to its dryness, but is used to make jellies. The young leaves and petals are also edible.

Couroupita guianensis, known by a variety of common names including cannonball tree, is a deciduous tree in the flowering plant family Lecythidaceae. It is native to lowland tropical rainforests of Central and South America, from Costa Rica, south to Brazil and northern Bolivia and it is cultivated in many other tropical areas throughout the world because of its fragrant flowers and large fruit, which are brownish grey. There are potential medicinal uses for many parts of Couroupita guianensis, and the tree has cultural and religious significance in South and Southeast Asia. In Sri Lanka and

Plantago ovata, known by many common names including blond plantain, desert Indianwheat, blond psyllium, and isabghol, is native to the Mediterranean region and naturalized in central, eastern, and south Asia and North America. A common source of psyllium, ground psyllium seed husks are indigestible, providing a source of soluble dietary fiber which may be fermented into butyric acid – a short-chain fatty acid – by butyrate-producing bacteria. Plantago ovata is commonly used for commercial products containing psyllium.

Bryonia dioica, known by the common names red bryony and white bryony, also English mandrake or ladies' seal, is a perennial climbing vine indigenous to Central and Southern Europe. It is a flowering plant in the cucumber family Cucurbitaceae with five-pointed leaves and blue or white flowers. The vine produces a red berry fruit.

Bacopa is a genus of 60 aquatic plants belonging to the family Plantaginaceae. It is commonly known as waterhyssop (or water hyssop, though this is more misleading as Bacopa is not very closely related to hyssop but simply has a somewhat similar appearance).

Hevea is a genus of flowering plants in the spurge family, Euphorbiaceae, with about ten members. It is also one of many names used commercially for the wood of the most economically important rubber tree, H. brasiliensis. The genus is native to tropical South America but is widely cultivated in other tropical countries and naturalized in several of them. It was first described in 1775.

Alternanthera is a genus of flowering plants in the family Amaranthaceae. It is a widespread genus with most species occurring in the tropical Americas, and others in Asia, Africa, and Australia. Plants of the genus may be known generally as joyweeds, or Joseph's coat. Several species are notorious noxious weeds.

Adenia is a genus of flowering plants in the passionflower family Passifloraceae. It contains about 100 species distributed in the Old World tropics and subtropics. The centers of diversity are in Madagascar, eastern and western tropical Africa, and Southeast Asia. The genus name Adenia comes from "aden", reported as the Arabic name for the plant by Peter Forsskål, the author of the genus.

Ocotea is a genus of flowering plants belonging to the family Lauraceae. Many are evergreen trees with lauroid leaves. There are over 520 species currently accepted within the genus, distributed mostly in tropical and subtropical areas of the Americas (around 300 species) including the Caribbean and West Indies, but also with some species in Africa, Madagascar and the Mascarene Islands. One species (O. foetens) is native to the Macaronesia (in Canary Islands and Madeira). The genus is suspected to be paraphyletic.

Pachira aquatica is a species of tropical wetland tree in the mallow family Malvaceae, native to Central and South America where it grows in swamps. It is known by its common names Malabar chestnut, French peanut, Guiana chestnut, provision tree, Saba nut, Monguba (Brazil), Pumpo (Guatemala) and Jelinjoche (Costa Rica) and is commercially sold under the names money tree and money plant. This tree is sometimes sold with a braided trunk and is commonly grown as a houseplant, although more commonly what is sold as a "Pachira aquatica" houseplant is in fact a similar species, Pachira glabra.

Hydnora africana is an achlorophyllous plant in the subfamily Hydnoroideae, native to southern Africa that is parasitic on the roots of members of the family Euphorbiaceae. It is also called jakkalskos or jackal food. The specific epithet africana means from Africa. Molecular data has suggested that Hydnoroideae is a "basal angiosperm" solidifying its place among the more primitive flowering plants. Hydnoraceae are the only angiosperms known to have no leaves or scales and are considered obligate parasites, completely dependent on their hosts to survive. The plant grows underground, except

Cabomba is a genus of perennial, rhizomatous, aquatic herbs in the family Cabombaceae native to tropical and subtropical America. It has divided submerged leaves in the shape of a fan (hence the vernacular name fanwort) and is much favoured by aquarists as an ornamental and oxygenating plant for fish tanks. One species, Cabomba caroliniana, is a nationally declared weed in Australia, where it has choked up waterways after escaping from aquaria.

Scutellaria baicalensis, with the common name Baikal skullcap or Chinese skullcap, is a species of flowering plant in the family Lamiaceae.

Hydnora is a group of parasitic plants described as a genus in 1775. It is native to Africa, Madagascar, and the Arabian Peninsula. Hydnora pollinates through brood-site mimicry. This is a method of pollination in which the plant emits a smell that is attractive to insects, so that the plant can trap the insect and allow it to take pollen so that it can pollinate other Hydnora. Hydnora cannot photosynthesize and rely on host plants for nutrients. They are plants that are rooted underground and have the ability to damage infrastructures by bursting through pavements.

Arnebia is a genus of flowering plants in the family Boraginaceae. There are about 36 species, most are located in the Mediterranean region and eastwards to the Himalayas and northern China, with one species extending into tropical Africa. The generic name "Arnebia" originates from the Arabic name shajaret el arneb. The Arnebia genus was first established by Pher Forsskal in 1775, and mostly confined to Asia with a few species occurring in the drier parts of North Africa

Themeda is a genus of plants in the grass family native to Asia, Africa, Australia, and Papuasia. There are about 18 to 26 species, many of which are native to Southeast Asia. Species Themeda anathera (Nees ex Steud.) Hack. - Afghanistan, Himalayas, Tibet Themeda arguens (L.) Hack. - Christmas grass - Sri Lanka, Southeast Asia, Papuasia, northern Australia Themeda arundinacea (Roxb.) A.Camus - Indochina, southern China, Indian Subcontinent, Malaysia, Indonesia Themeda avenacea (F. Muell.) Maiden & Betche - oat kangaroo grass - Australia Themeda caudata (Nees ex Hook. & Arn.) A.Camus -

Aerva is a genus of plants in the family Amaranthaceae. Its species are native to the palaeotropics, throughout continental Africa, Madagascar and smaller islands (Mauritius and Socotra), through parts of the Middle East, India, and southeast Asia. Aerva javanica is an alien in northern Australia. At least four species in the genus have acquired the C4 carbon fixation pathway.

Themeda triandra is a species of C4 perennial tussock-forming grass widespread in Africa, Australia, Asia and the Pacific. In Australia it is commonly known as kangaroo grass and in East Africa and South Africa it is known as red grass and red oat grass or as rooigras in Afrikaans. Kangaroo grass was formerly thought to be one of two species, and was named Themeda australis. The plant has traditional uses as food and medicine in Africa and Australia. Indigenous Australians harvested it to make bread and string for fishing nets around 30,000 years ago. It was used as livestock feed in early

Pachira is a genus of tropical trees distributed in Central and South America and the Caribbean, ranging from Mexico to Bolivia and southern Brazil. They are classified in the subfamily Bombacoideae of the family Malvaceae. Previously the genus was assigned to Bombacaceae. Prior to that the genus was found in the (now obsolete) Sterculiaceae. 54 species are currently accepted. They form small or large trees with digitate leaves, and the fruit an oval woody one-celled capsule opening by a number of divisions and containing many seeds.

Pouteria is a genus of flowering trees in the gutta-percha family, Sapotaceae. The genus is widespread throughout the tropical Americas, with outlier species in Cameroon and Malesia. It includes the green sapote (P. viridis), the mamey sapote (P. sapota), and the abiu (P. caimito). Commonly, this genus is known as pouteria trees. Pouteria is related to Manilkara, another genus that produces hard and heavy woods (e.g. balatá, M. bidentata) used commonly for tropical construction, as well as edible fruit (such as sapodilla, M. zapota).

Palicourea is a genus of flowering plants in the family Rubiaceae. It contains 694 species, which range from shrubs to small trees, and is distributed throughout the New World tropics. These plants are closely related to Psychotria and in particular its subgenus Heteropsychotria. Indeed, it seems to be nothing else but a distinctively-flowered offshoot of Heteropsychotria; arguably, it would thus need to be merged into Psychotria to make that genus monophyletic. On the other hand, Psychotria is extremely diverse already, so it is probably more practical to move the more distantly related

Oncoba spinosa, the snuff-box tree, fried egg tree or fried-egg flower, is a plant species in the genus Oncoba traditionally placed in the family Flacourtiaceae, but now placed in the willow family, Salicaceae. It is a small deciduous tree (usually no more than 5 m in height, but occasionally to 12 m (39 ft), that has simple leaves. The 9 cm (3.5 in) wide flowers have up to seventeen white petals and attractive with a yellow centre due to the stamens, resembling a fried egg. They appear on the tree from just before or around the time the new leaves are produced and the tree is in bloom for up

Mayaca is a genus of flowering plants, often placed in its own family, the Mayacaceae (or Mayaceae in earlier systems). In the APG II system of 2003, it is assigned to the order Poales in the clade commelinids. The Cronquist system, of 1981, also recognised such a family and placed it in the order Commelinales in the subclass Commelinidae. The group is widely distributed in Latin America from Mexico to Argentina, as well as in the West Indies, the southeastern United States, and central Africa.

Maesa is a genus of flowering plants. It is placed in the family Primulaceae, subfamily Maesoideae, for which it is the sole genus (monotypic). Previously it was placed in Myrsinaceae, or in a family of its own, Maesaceae. There are 184 accepted species native to tropical and subtropical Africa, Asia, and the Pacific, the majority of which occur in Malesia, New Guinea, western Asia, and the Pacific Islands. These plants are vines, shrubs, and trees up to 12 meters tall.

Cabomba aquatica is a rhizomatous, perennial, aquatic herb in the family Cabombaceae native to South America. It occurs in fresh standing water or in lakes and rivers with slight currents.

Pyrus spinosa (syn. Pyrus amygdaliformis), the almond-leaved pear, is a species of flowering plant in the family Rosaceae, native to the northern Mediterranean region. It has white flowers which bloom in April–May. The fruits are bitter and astringent. It hybridizes easily with Pyrus communis and Pyrus pyraster.

Goupia is a neotropical genus of flowering plants and the sole genus included in the family Goupiaceae. There are three species, all found in tropical northern South America.

Couroupita is a genus of flowering plants in the family Lecythidaceae first described as a genus in 1775. It is native to tropical South America and Central America. Species Couroupita guianensis - Cannonball tree -Guyana, Colombia, Ecuador east to Amapá and south to Bolivia; naturalized in the West Indies as well as in Bangladesh, Sri Lanka and Andaman & Nicobar Couroupita nicaraguarensis – Bala de cañón, coco de mono, paraíso, zapote de mico, or zapote de mono -Nicaragua, Costa Rica, Honduras, Panama Couroupita subsessilis - northern Brazil, northern Peru

Passiflora coccinea (common names scarlet passion flower, red passion flower) is a fast-growing vine. The vine is native to northern South America. It produces edible fruit. Most plants cultivated as Passiflora coccinea turn out to be Passiflora miniata Vanderpl.
