Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants, living in diverse habitats on every continent except Antarctica. The world's richest diversity of orchid genera and species is in the tropics. Many species are epiphytes, living on trees. The flowers and their pollination mechanisms are highly specialized, attracting insect pollinators by colour, pattern, scent, pheromones, and sometimes by mimicking female insects. Orchids have very small seeds,

A cactus (pl.: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae, a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. The word cactus derives, through Latin, from the Ancient Greek word κάκτος (káktos), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of Rhipsalis baccifera, which is also found in

Rosaceae, the rose family, is a family of flowering plants that includes 4,828 known species in 91 genera. The name is derived from the type genus Rosa. The family includes herbs, shrubs, and trees. Most species are deciduous, but some are evergreen. They have a worldwide range but are most diverse in the Northern Hemisphere. Many economically important products come from the Rosaceae, including various edible fruits, such as apples, pears, quinces, apricots, plums, cherries, peaches, raspberries, blackberries, loquats, strawberries, rose hips, hawthorns, and almonds. The family also includes

Solanaceae, commonly known as the nightshades, is a family of flowering plants in the order Solanales. The family contains approximately 2,700 species, several of which are used as agricultural crops, medicinal plants, and ornamental plants. Many members of the family have high alkaloid contents, making some highly toxic, but many—such as tomatoes, potatoes, eggplants, and peppers—are commonly used in food. Originating in South America, Solanaceae now inhabit every continent on Earth except Antarctica. After the K–Pg extinction event they rapidly diversified and have adapted to live in

Malvaceae, or the mallows, is a family of flowering plants estimated to contain 244 genera with 4225 known species. Well-known members of economic importance include cacao, cola, cotton, okra, roselle and durian. There are also some genera containing familiar ornamentals, such as Alcea (hollyhock), Malva (mallow), and Tilia (lime or linden tree). The genera with the largest numbers of species include Hibiscus (434 species), Pavonia (291 species), Sida (275 species), Ayenia (216 species), Dombeya (197 species), and Sterculia (181 species).

Luffa – commonly called 'luffa' or ‘luffa squash'; sometimes spelled loofah. Young fruits may be cooked;

Euphorbiaceae, the spurge family, is a large family of flowering plants. In English, they are also commonly called euphorbias, which is also the name of the type genus of the family. Most spurges, such as Euphorbia paralias, are herbs, but some, especially in the tropics, are shrubs or trees, such as Hevea brasiliensis. Some, such as Euphorbia canariensis, are succulent and resemble cacti because of convergent evolution. This family has a cosmopolitan global distribution. The greatest diversity of species is in the tropics; however, the Euphorbiaceae also have many species in nontropical

The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous geophytes, often growing from bulbs although some have rhizomes. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. The flowers are large with six colored or patterned petaloid tepals (undifferentiated petals and sepals) arranged in two whorls of three, six stamens and a superior ovary. The fruit can be a berry or

Ranunculaceae ( rə-nung-kew-LAY-see-e(y)e, buttercup or crowfoot family; Latin rānunculus "little frog", from rāna "frog") is a large family of flowering plants, distributed worldwide. As of February 2026, World Flora Online accepted 53 genera and over 3,700 species. The largest genera are Ranunculus with more than 1,600 species, Delphinium with more than 500, and Clematis with almost 400.

Rubiaceae is a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 14,200 species in about 615 genera, which makes it the fourth-largest angiosperm family by number of species. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source

The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe (or leaf-like bract). Also known as the arum family, members are often colloquially known as aroids. This family of 114 genera and about 3,750 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.

The Rutaceae is a family, commonly known as the rue or citrus family, of flowering plants, usually placed in the order Sapindales. Species of the family generally have flowers that divide into four or five parts, usually with strong scents. They range in form and size from herbs to shrubs and large trees. The most economically important genus in the family is Citrus, which includes the orange (C. × sinensis), lemon (C. × limon), grapefruit (C. × paradisi), and lime (various). Boronia is a large Australian genus, some members of which are plants with highly fragrant flowers and are used in

Convolvulaceae, commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato.

Apocynaceae (, from Apocynum, Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Notable members of the family include oleander, dogbanes, milkweeds, wax plants and periwinkles. The family is native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members as well. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A

Myrtaceae, the myrtle family, is a family of dicotyledonous plants placed within the order Myrtales. Myrtle, pōhutukawa, bay rum tree, clove, guava, acca (feijoa), allspice, and eucalyptus are some notable members of this group. All species are woody, contain essential oils, and have flower parts in multiples of four or five. The leaves are evergreen, alternate to mostly opposite, simple, and usually entire (i.e., without a toothed margin). The flowers have a base number of five petals, though in several genera, the petals are minute or absent. The stamens are usually very conspicuous,

The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family contains around 5,500 described species in about 90 genera – the largest being the "true sedges" (Carex), with over 2,000 species.

It is included in the eudicot order Caryophyllales in the APG III system, alongside 33 other families, including Amaranthaceae, Cactaceae, and Polygonaceae. It is a large family, with 105 genera and about 2,625 known species. This cosmopolitan family of mostly herbaceous plants is best represented in temperate climates, with a few species growing on tropical mountains. Some of the more commonly known members include pinks and carnations (Dianthus), and firepink and campions (Silene). Many

Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide. They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as Sassafras, are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus Cassytha is unique in the Lauraceae in that its members are parasitic vines. Many species

Bougainvillea ( BOO-gən-VIL-ee-ə, US also BOH-) is a genus of thorny ornamental vines, bushes, and trees belonging to the family Nyctaginaceae. They are native to Mexico, Brazil, Bolivia, Paraguay, Peru, and Argentina. There are between 4 and 22 species in the genus. The inflorescence consists of large colorful sepal-like bracts which surround three simple waxy flowers, gaining popularity for the plant as an ornamental. The plant is named after explorer Louis Antoine de Bougainville (1729–1811), after it was documented on one of his expeditions.

Amaranthaceae ( AM-ər-an-THAY-see-ee, -⁠eye) is a family of flowering plants commonly known as the amaranth family, in reference to its type genus Amaranthus. It includes the former goosefoot family Chenopodiaceae and contains about 165 genera and 2,040 species, making it the most species-rich lineage within its parent order, Caryophyllales.

The Polygonaceae are a family of flowering plants known informally as the knotweed family or smartweed—buckwheat family in the United States. The name is based on the genus Polygonum, and was first used by Antoine Laurent de Jussieu in 1789 in his book, Genera Plantarum. The name may refer to the many swollen nodes the stems of some species have, being derived from Greek (poly meaning 'many' and gony meaning 'knee' or 'joint'). Alternatively, it may have a different origin, meaning 'many seeds'. The Polygonaceae comprise about 1,200 species distributed into about 48 genera. The largest genera

The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with about 4,250 known species spread across 124 genera, making it the 14th most speciose family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (Erica, Cassiope, Daboecia, and Calluna for example).

The Urticaceae are a family, the nettle family, of flowering plants. The family name comes from the genus Urtica. The Urticaceae family includes a number of well-known and useful plants, including nettles in the genus Urtica, Ramie (Boehmeria nivea), māmaki (Pipturus albidus), and ajlai (Debregeasia saeneb). The family includes about 2,625 species, grouped into 53 genera. The largest genera are Pilea (500 to 715 species), Elatostema (300 species), Urtica (80 species), and Cecropia (75 species). Cecropia contains many myrmecophytes. Urticaceae species can be found worldwide, but most species

The Malvales are an order of flowering plants. As circumscribed by APG II-system, the order includes about 6000 species within nine families. The order is placed in the eurosids II, which are part of the eudicots. The plants are mostly shrubs and trees; most of its families have a cosmopolitan distribution in the tropics and subtropics, with limited expansion into temperate regions. An interesting distribution occurs in Madagascar, where three endemic families of Malvales (Sphaerosepalaceae, Sarcolaenaceae and Diegodendraceae) occur. Many species of Malvaceae, sensu lato (in the broad sense),

The Vitaceae, also called the grape family, is a family of flowering plants that has 20 genera and around 910 known species in its monotypic order Vitales, including common plants such as grapevines (Vitis spp.) and Virginia creeper (Parthenocissus quinquefolia). The family name is derived from the genus Vitis. Most of its members are distributed in tropical areas and many are dominant climbers with ecological significance, but some could be shrubs or tree. Some species of genus Tetrastigma serve as hosts to parasitic plants in another family Rafflesiaceae. Some produce pearl bodies that may

Plantaginaceae, the plantain family or veronica family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain". In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales.

Iridaceae is a family of plants in order Asparagales, taking its name from the irises. It has a nearly global distribution, with 69 accepted genera with a total of about 2500 species. It includes a number of economically important cultivated plants, such as species of Freesia, Gladiolus, and Crocus, as well as the crop saffron. Members of this family are perennial plants, with a bulb, corm or rhizome. The plants grow erect, and have leaves that are generally grass-like, with a sharp central fold. Some examples of members of this family are the blue flag and yellow flag.

The Papaveraceae, informally called the poppy family, are an economically important family of about 42 genera and approximately 775 known species of flowering plants in the order Ranunculales. The family is cosmopolitan, occurring in temperate and subtropical climates (mostly in the northern hemisphere) like Eastern Asia as well as California in North America. It is almost unknown in the tropics. Most are herbaceous plants, but a few are shrubs and small trees. The family currently includes two groups that have been considered to be separate families: Fumariaceae and Pteridophyllaceae.

Asparagaceae, known as the asparagus family, is a family of flowering plants, placed in the order Asparagales of the monocots. The family name is based on the edible garden asparagus, Asparagus officinalis. This family includes both common garden plants as well as common houseplants. The garden plants include asparagus, yucca, bluebell, lily of the valley, and hosta, and the houseplants include snake plant, corn cane, spider plant, and plumosus fern. The Asparagaceae is a morphologically heterogenous family with the included species varying widely in their appearance and growth form. It has a

The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of about 80 genera and 3700 known species, native mainly to the tropical Americas, with several species found in the American subtropics and one in tropical west Africa, Pitcairnia feliciana. It is the sister group to the Typhaceae, and together this clade is sister to the remaining lineages in the Poales. Bromeliaceae is the only family within the order that has septal nectaries and inferior ovaries. These inferior ovaries characterize the Bromelioideae, a subfamily of the Bromeliaceae. The family includes both
