Plants named in 1826

Liliales is an order of monocotyledonous flowering plants in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web system, within the lilioid monocots. This order of necessity includes the family Liliaceae. The APG III system (2009) places this order in the monocot clade. In APG III, the family Luzuriagaceae is combined with the family Alstroemeriaceae and the family Petermanniaceae is recognized. Both the order Lililiales and the family Liliaceae have had a widely disputed history, with the circumscription varying greatly from one taxonomist to another. Previous members of this order,

Euphorbia milii, the crown-of-thorns, Christ plant or Christ's thorn, is a species of flowering plant in the spurge family, Euphorbiaceae, native to Madagascar. The specifies commemorates Baron Milius, once Governor of Réunion, who introduced the species to France in 1821. The native Malagasy name for this plant, songosongo, has also been applied to several other Euphorbia species. It is thought that the species was introduced to the Middle East in ancient times; legend, which associates it with the crown-of-thorns worn by Jesus Christ upon his crucifixion, has likely influenced the common

The Agaricaceae are a family of basidiomycete fungi and include the genus Agaricus, as well as basidiomycetes previously classified in the families Tulostomataceae, Lepiotaceae, and Lycoperdaceae.

Lablab purpureus is a species of bean in the family Fabaceae. It is native to sub-Saharan Africa and it is cultivated throughout the tropics for food. English language common names include hyacinth bean, lablab-bean bonavist bean/pea, dolichos bean, seim or sem bean, lablab bean, Egyptian kidney bean, Indian bean, bataw and Australian pea. Lablab is a monotypic genus.

Zantedeschia is a genus of eight species of herbaceous, perennial, flowering plants in the aroid family, Araceae, native to southern Africa (from South Africa northeast to Malawi). The genus has been introduced, in some form, on every continent other than Antarctica. Common names include arum lily for Z. aethiopica, calla and calla lily for Z. elliottiana and Z. rehmannii. However, members of this genus are not true lilies (which belong to the family Liliaceae), and the genera Arum and Calla, although related, are distinct from Zantedeschia, despite visual similarities. The colourful flowers

Saururaceae is a plant family comprising four genera and seven species of herbaceous flowering plants native to eastern and southern Asia and North America. The family has been recognised by most taxonomists, and is sometimes known as the "lizard's-tail family". The APG IV system (2016; unchanged from the 2009 APG III system, the 2003 APG II system and the 1998 APG system) assigned it to the order Piperales in the clade magnoliids.

Platanaceae, the plane family, is a family of flowering plants in the order Proteales. The family consists of only a single extant genus Platanus, with twelve known species. The plants are tall trees, native to temperate and subtropical regions of the Northern Hemisphere. The hybrid London plane is widely planted in cities worldwide.

Gac, from the Vietnamese gấc (pronounced [ɣək˦˥]), scientific name Momordica cochinchinensis, is a species of plant in the melon and cucumber family Cucurbitaceae native to countries throughout Southeast Asia and to Queensland, Australia. It is notable for its vivid orange-reddish color resulting from a mix of beta-carotene and lycopene.

The Hernandiaceae are a family of flowering plants (angiosperms) in the order Laurales. Consisting of five genera with about 58 known species, they are distributed over the world's tropical areas, some of them widely distributed in coastal areas, but they occur from sea level to over 2000 m. The family is closely related to the Lauraceae, and many species inhabit laurel forest habitat; they have laurel-like (lauroid) leaves. Based on morphology, chromosome numbers, geographical distribution, and phylogenetic analyses, the family is clearly divided into two groups that have been given the rank

Zantedeschia aethiopica, commonly known as calla lily and arum lily, is a species of flowering plant in the family Araceae, native to southern Africa in Lesotho, South Africa, and Eswatini.

Lithocarpus is a genus in the beech family, Fagaceae. Trees in this genus are commonly known as the stone oaks and differ from Quercus primarily because they produce insect-pollinated flowers on erect spikes and the female flowers have short styles with punctate stigmas. At current, around 340 species have been described, mostly restricted to Southeast Asia. Fossils show that Lithocarpus formerly had a wider distribution, being found in North America and Europe during the Eocene to Miocene epochs. The species extend from the foothills of the Hengduan Mountains, where they form dominant stands

Himantoglossum is a genus of orchids native to the Canary Islands, Europe, southwest Asia and northern Africa. Its members generally have a labellum which is divided into three parts, of which the middle part is the longest. The genera Comperia and Barlia are now included in Himantoglossum.

Abutilon indicum (Indian abutilon, Indian mallow) is a small shrub in the family Malvaceae, native to tropical and subtropical regions. This plant is a valuable medicinal and ornamental plant, its roots and leaves being used for curing fevers. It has been widely introduced outside of its native range, and is considered invasive on certain tropical islands.

Lacistemataceae is a small flowering plant family. There are two genera: Lacistema (12 species) Lozania (5 species) They are small trees (to 15 metres tall) and shrubs (to 5 metres tall) that are native to the subtropical and tropical regions of the Americas (also known as the Neotropics). The leaves are on alternate sides of the stem and maybe surrounded by a pair of stipules. The Inflorescence located between the leaf and the stem (axil) are either catkins (in Lacistema) or racemes (in Lozania). Each flower (mostly bisexual) approximately one millimetre in length consist of a disc with

Cunninghamia is a genus of one or two living species of evergreen coniferous trees in the cypress family Cupressaceae. They are native to China, northern Vietnam and Laos, and perhaps also Cambodia. They may reach 70 m (230 ft) in height. In vernacular use, it is most often known as Cunninghamia, but is also sometimes called "China-fir" (though it is not a fir). The genus name Cunninghamia honours Dr. James Cunningham, a British doctor who introduced this species into cultivation in 1702 and botanist Allan Cunningham.

The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae) that contains around 3630 species. Species typically have a single (monandrous), fertile anther which is erect and basitonic.

Magnolia × soulangeana (Magnolia denudata × Magnolia liliiflora), the saucer magnolia or sometimes the tulip tree, is a hybrid flowering plant in the genus Magnolia and family Magnoliaceae. It is a deciduous tree with large, early-blooming flowers in various shades of white, pink, and purple. It is one of the most commonly used magnolias in horticulture, being widely planted in the British Isles, especially in the south of England; and in the United States, especially the east and west coasts.

Ipomoea cairica is a vining, herbaceous, perennial plant with palmate leaves and large, showy white to lavender flowers. A species of morning glory, it has many common names, including mile-a-minute vine, Messina creeper, Cairo morning glory, coast morning glory and railroad creeper. The species name cairica translates to "from Cairo", the city where this species was first collected.

Himantoglossum hircinum, the lizard orchid, is a species of orchid in the genus Himantoglossum found in Europe and North Africa.

Glebionis is a small genus of flowering plants in the family Asteraceae, native to Europe and the Mediterranean region. The species were formerly treated in the genus Chrysanthemum. A 1999 ruling of the International Botanical Congress redefined the type species for that genus as the economically important florist's chrysanthemum, thereby excluding the species now included in Glebionis. Glebionis species have been hybridized with related Argyranthemum species to create cultivars of garden marguerites. Species Glebionis coronaria (syn. Chrysanthemum coronarium) – crown daisy - central, +

Artocarpus lacucha, also known as monkey jack or monkey fruit, is a tropical evergreen tree species of the family Moraceae. It is distributed throughout the Indian subcontinent and Southeast Asia. The tree is valued for its wood; its fruit is edible and is believed to have medicinal value. In Northeastern Thailand, the wood is used to make pong lang, a local traditional instrument. The stilbenoid oxyresveratrol can be isolated from the heartwood of Artocarpus lacucha as well as in Puag Haad, the light brown powder obtained from the aqueous extract of the wood chips of A. lakoocha by boiling,

Strobilanthes is a genus of about 350 species of flowering plants in the family Acanthaceae, mostly native to tropical Asia and Madagascar, but with a few species extending north into temperate regions of Asia. Many species are cultivated for their two-lipped, hooded flowers in shades of blue, pink, white and purple. Most are frost-tender and require protection in frost-prone areas. The genus is most famed for its many (but not all) species which bloom on long cycles of several years, such as Strobilanthes wightii which blooms every thirteen years.

Zeuxine, commonly known as verdant jewel orchids, is a genus of about eighty species of orchids in the tribe Cranichideae. They are native to parts of tropical Africa, Asia, Southeast Asia, New Guinea, Australia and some Pacific Islands. They have relatively narrow, dark green leaves and small, dull-coloured resupinate flowers with the dorsal sepal and petals overlapping to form a hood over the column. The labellum has a pouched base and its tip has two lobes.

Barringtonia racemosa, commonly known as powder-puff tree, is a species of tree in the family Lecythidaceae. It is found in coastal swamp forests and on the edges of estuaries in the Indian Ocean, starting at the east coast of Mozambique and KwaZulu-Natal (South Africa) to Madagascar, India, Sri Lanka, Malesia, Maldives, Thailand, Laos, southern China, northern Australia, coastal Taiwan, the Ryukyu Islands and many Polynesian islands. The 1889 book 'The Useful Native Plants of Australia' records that the Indigenous people of the Mitchell River District called this plant "Yakooro" and that

Spergularia media (syn. S. maritima) is a species of flowering plant in the family Caryophyllaceae known by the common names media sandspurry and greater sea-spurrey. It is native to Eurasia and the Mediterranean, where it grows in many types of habitat, including disturbed areas, including places with saline substrates, such as salt marshes and beaches. It is known in many other parts of the world as an introduced species and a common roadside weed. In North America it is a "highway halophyte", often springing up at the margins of roads that are heavily salted in the winter.

Pachyrhizus is a genus of flowering plants in the legume family, Fabaceae. It includes five or species of herbs and subshrubs native to the tropical and subtropical Americas, ranging from northern Mexico to northwestern Argentina. Typical habitat is seasonally-dry tropical forest and thicket, often at forest margins, in scrub vegetation, and in open grassy areas. Plants in the genus grow from large, often edible taproots.

Lupinus mutabilis is a species of lupin grown in the Andes, mainly for its edible bean. Vernacular names include tarwi (in Quechua II, pronounced tarhui), chocho, altramuz, Andean lupin, South American lupin, Peruvian field lupin, and pearl lupin. Its nutrient-rich seeds are high in protein, as well as a good source for cooking oil. However, their bitter taste has made L. mutabilis relatively unknown outside the Andes, though modern technology makes removing the bitter alkaloids easier. Like other species of lupin beans, it is expanding in use as a plant-based protein source.

Conringia orientalis is a species of flowering plant in the mustard family known by the common name hare's ear mustard. It is native to Eurasia but it is known elsewhere as an introduced species and sometimes a noxious weed. It is weedy in its native range and also in North America, where it is a widespread invasive species, especially in central Canada. It is an annual herb producing an unbranched erect stem 30 to 70 centimetres (12 to 28 inches) in height. The thick, waxy leaves are generally oval in shape, up to 9 centimetres (3+1⁄2 inches) long, and clasp the stem at their bases. The

Arracacia xanthorrhiza is a root vegetable which originates in the Andes. Its starchy taproot is a major commercial crop and a popular food item across South America.

Vernonia amygdalina, a member of the daisy family, is a small to medium-sized shrub that grows in tropical Africa. V. amygdalina typically grows to a height of 2–5 m (6.6–16.4 ft). The leaves are elliptical and up to 20 cm (7.9 in) long. Its bark is rough. V. amygdalina is commonly called bitter leaf in English because of its bitter taste.
