Brassicaceae or (the older but equally valid) Cruciferae is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall

The Chenopodioideae are a subfamily of the flowering plant family Amaranthaceae in the APG III system, which is largely based on molecular phylogeny, but were included – together with other subfamilies – in the family Chenopodiaceae, or goosefoot family, in the Cronquist system. Food species comprise spinach (Spinacia oleracea), Good King Henry (Blitum bonus-henricus), several Chenopodium species (quinoa, kañiwa, fat hen), orache (Atriplex spp.), and epazote (Dysphania ambrosioides). The name is Greek for goosefoot, the common name of a genus of plants having small greenish flowers.

Malvoideae is a botanical name at the rank of subfamily, which includes in the minimum the genus Malva. It was first used by Burnett in 1835, but was not much used until recently, where, within the framework of the APG System, which unites the families Malvaceae, Bombacaceae, Sterculiaceae and Tiliaceae of the Cronquist system, the aggregate family Malvaceae is divided into 9 subfamilies, including Malvoideae. The Malvoideae of Kubitzki and Bayer includes 4 tribes: Malveae (Abutilon, Alcea, Malva, Sidalcea etc.) Gossypieae (Gossypium, the cottons etc.) Hibisceae (Hibiscus etc.) Kydieae - and

Asphodeloideae is a subfamily of the monocot family Asphodelaceae in the order Asparagales. It has previously been treated as a separate family, Asphodelaceae sensu stricto. The family Asphodelaceae has now been proposed to be a nomen conservandum, and the proposal has been recommended for ratification in 2017. In that case, Asphodelaceae will have priority over Xanthorrhoeaceae. This is reflected in the APG IV family lists. The subfamily name is derived from the generic name of the type genus, Asphodelus. Members of this group can be found growing native in coastal Southern Africa, Central

Scilloideae (named after the genus Scilla, "squill") is a subfamily of bulbous plants within the family Asparagaceae. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus Hyacinthus. This subfamily contains many popular spring-flowering garden bulbs, such as hyacinths (Hyacinthus), grape hyacinths (Muscari), Puschkinia, bluebells (Hyacinthoides) and squills (Scilla) Scilloideae are distributed mostly in Mediterranean climates, including South Africa, Central Asia and South America. Their flowers have six tepals and six stamens with a superior ovary, which

Bombacoideae is a subfamily of the mallow family, Malvaceae. It contains herbaceous and woody plants. Their leaves are alternate, commonly palmately lobed, with small and caducous stipules. The flowers are hermaphroditic and actinomorphic; the calyx has 5 sepals united at the base, which are not accompanied by an epicalyx (involucel). The corolla has 5 free petals and an androecium of numerous stamens, typically with free filaments which are not fused in a staminal tube (column). The pollen is smooth and the ovary superior and pluricarpellate. The fruits are schizocarpous or capsular.

The Asclepiadoideae are a subfamily of flowering plants in the family Apocynaceae. Formerly, these plants together with those now in the Apocynaceae subfamilies Periplocoideae and Secamonoideae were treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family. They form a group of perennial herbs, twining shrubs, lianas or rarely trees but notably also contain a significant number of leafless stem succulents. The name comes from the type genus Asclepias (milkweeds). There are 348 genera, with about 2,900 species. They are mainly located in the

Nepetoideae is a subfamily of plants in the family Lamiaceae. As of July 2020, the Angiosperm Phylogeny Website (APweb) accepted the following genera:

Amaryllidoideae (Amaryllidaceae s.s., amaryllids) is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG IV, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae (the old family Amaryllidaceae), and the others are Allioideae (the old family Alliaceae) and Agapanthoideae (the old family Agapanthaceae). The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution.

Opuntioideae is a subfamily of the cactus family, Cactaceae. It contains 15 genera divided into five tribes. The subfamily encompasses roughly 220–250 species, and is geographically distributed throughout the New World from Canada, to Argentina. Members of this subfamily have diverse habits, including small geophytes, hemispherical cushions, shrubs, trees, and columnar cacti consisting of indeterminate branches or determinate terete or spherical segments.

Lobelioideae is a subfamily of the plant family Campanulaceae. It contains 32 genera, totalling about 1200 species. Some of the larger genera are Lobelia, Siphocampylus, Centropogon, Burmeistera and Cyanea. They are perennials, sometimes annuals, ranging in form from herbs to small trees. Most species are tropical in distribution, but in total this subfamily occurs almost worldwide, being absent only from Arctic regions, central Asia and the Near East. The subfamily is particularly diverse in Hawaii, where well over 100 species of Hawaiian lobelioids have radiated from a single introduction.

Apocynoideae is a subfamily of the flowering plant family Apocynaceae (order Gentianales), also called the 'dogbane' or milkweed family, containing about 860 species across 78 genera. Several are of pharmacological interest; Strophanthus has furnished highly effective arrow poisons, due to their cardiac glycoside content. Apocynoideae also includes many popular landscaping and ornamental species, one of the best-known, and most infamous, being the oleander (Nerium oleander); the subfamily also contains remarkable pachycaul genera like Adenium and Pachypodium.

Solanoideae is a subfamily of the flowering plant family Solanaceae, and is sister to the subfamily Nicotianoideae. Within Solanaceae, Solanoideae contains some of the most economically important genera and species, such as the tomato (Solanum lycopersicum), potato (Solanum tuberosum), eggplant or aubergine (Solanum melongena), chili and bell peppers (Capsicum), mandrakes (Mandragora), and jimson weeds (Datura). This subfamily consists of several well-established tribes: Capsiceae, Datureae, Hyoscyameae, Juanulloeae, Lycieae, Nicandreae, Nolaneae, Physaleae, Solandreae, and Solaneae. The

Conifers are a group of vascular plants and a subset of gymnosperms. They are primarily perennial, woody trees and shrubs, mostly evergreen with a regular branching pattern, reproducing with male and female cones, usually on the same tree. They are wind-pollinated and the seeds are usually dispersed by the wind. Taxonomically, they make up the division Pinophyta, also known as Coniferae. All extant conifers, except for the gnetophytes, are perennial woody plants with secondary growth. There are over 600 living species. Conifers first appear in the fossil record over 300 million years ago in

Bromelioideae is a subfamily of the bromeliads (Bromeliaceae). This subfamily is the most diverse in the family, represented by the greatest number of genera with about 40. Most of the plants in this group are epiphytes, though some have evolved in, or will adapt to, terrestrial conditions. This subfamily features the most plant types which are commonly cultivated by people, including the pineapple.

Tillandsioideae is a subfamily of plants in the bromeliad family Bromeliaceae. This subfamily contains the greatest number of species (about 1,400). Most are epiphytic or lithophytic, growing in trees or on rocks where they absorb water and nutrients from the air. Spanish moss of the genus Tillandsia is a well-known species. Bromeliads in the genera Guzmania and Vriesea are the more commonly cultivated members of this subfamily.

Byttnerioideae is a subfamily of the flowering plant family Malvaceae. Byttneria is the type genus for the subfamily. Byttneria is now treated as synonym of Ayenia.

Sapindoideae is a subfamily of flowering plants in the soapberry family, Sapindaceae. It includes a number of fruit trees, including lychees, longans, rambutans, and quenepas.

Morinoideae is a subfamily of plants in the family Caprifoliaceae, order Dipsacales. It was at one time recognized as the separate family Morinaceae. The genus Morina has also been included in a separate family Dipsacaceae, currently included in Caprifoliaceae. Three genera have been included in this subfamily: Acanthocalyx A. alba, A. albus, A. delavayi, A. nepalensis. Cryptothladia C. chinensis, C. chlorantha, C. kokonorica, C. polyphylla Morina M. couteriana, M. longifolia, M. persica M. longifolia has the common names "whorl flower" and "Persian steppe flower." This species has cultivars:

Cestroideae (syn. Browallioideae) is a subfamily of the plant family Solanaceae, the nightshades. It currently contains the three tribes and seven genera, as follows: Browallieae Hunz. Browallia L. Streptosolen (Benth.) Miers Cestreae Don Cestrum L. Sessea Ruiz & Pav. Vestia Willd. Salpiglossideae (Benth.) Hunz. Reyesia Gay Salpiglossis Ruiz & Pav. With the (current) exceptions of the genera Sessea and Reyesia, the subfamily furnishes many colourful garden plants of considerable horticultural merit.
