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 c. 4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron, and various common heaths and heathers.
Fabales is an order of flowering plants included in the rosid group of the eudicots in the Angiosperm Phylogeny Group II classification system. In the APG II circumscription, this order includes the families Fabaceae or legumes, Quillajaceae, Polygalaceae or milkworts, and Surianaceae. Under the Cronquist system and some other plant classification systems, the order Fabales contains only the family Fabaceae. In the classification system of Dahlgren the Fabales were in the superorder Fabiflorae with three families corresponding to the subfamilies of Fabaceae in APG II. The other families treated in the Fabales by the APG II classification were placed in separate orders by Cronquist, the Polygalaceae within its own order, the Polygalales, and the Quillajaceae and Surianaceae within the Rosales.
Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales. It has previously been treated as a separate family, Agavaceae. The group includes many well-known desert and dry-zone types, such as the agaves and yuccas. About 640 species are placed in around 23 genera; they are widespread in the tropical, subtropical, and warm temperate regions of the world.
In biological classification, a subfamily is an auxiliary (intermediate) taxonomic rank, next below family but more inclusive than genus. Standard nomenclature rules end botanical subfamily names with "-oideae", and zoological subfamily names with "-inae".
The Araliaceae are a family of flowering plants composed of about 43 genera and around 1500 species consisting of primarily woody plants and some herbaceous plants commonly called the ginseng family. The morphology of Araliaceae varies widely, but it is predominantly distinguishable based on its woody habit, tropical distribution, and the presence of simple umbels.
Ranunculaceae is a family of over 2,000 known species of flowering plants in 43 genera, distributed worldwide.
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 c. 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.
Lythraceae is a family of flowering plants, including 32 genera, with about 620 species of herbs, shrubs, and trees. The larger genera include Cuphea, Lagerstroemia (56), Nesaea (50), Rotala (45), and Lythrum (35). It also includes the pomegranate and the water caltrop. Lythraceae has a worldwide distribution, with most species in the tropics, but ranging into temperate climate regions as well.
Hamamelidaceae, commonly referred to as the witch-hazel family, is a family of flowering plants in the order Saxifragales. The clade consists of shrubs and small trees positioned within the woody clade of the core Saxifragales. An earlier system, the Cronquist system, recognized Hamamelidaceae in the Hamamelidales order.
The Dryopteridaceae are a family of leptosporangiate ferns in the order Polypodiales. They are known colloquially as the wood ferns. In the Pteridophyte Phylogeny Group classification of 2016 (PPG I), the family is placed in the suborder Polypodiineae. Alternatively, it may be treated as the subfamily Dryopteridoideae of a very broadly defined family Polypodiaceae sensu lato.
Scilloideae is a subfamily of bulbous plants within the family Asparagaceae. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus Hyacinthus. Scilloideae or Hyacinthaceae include many familiar garden plants such as Hyacinthus (hyacinths), Hyacinthoides (bluebells), Muscari and Scilla and Puschkinia. Some are important as cut flowers.
Asphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is Asphodelus.
Linaceae is a family of flowering plants. The family is cosmopolitan, and includes about 250 species in 14 genera, classified into two subfamilies: the Linoideae and Hugonioideae. Leaves of the Linaceae are always simple; arrangement varies from alternate to opposite or whorled. The hermaphroditic, actinomorphic flowers are pentameric or, very rarely, tetrameric.
The family Pandaceae consists of three genera that were formerly recognized in the Euphorbiaceae. Those are:
Didiereaceae is a family of flowering plants found in continental Africa and Madagascar. It contains 20 species classified in three subfamilies and six genera. Species of the family are succulent plants, growing in sub-arid to arid habitats. Several are known as ornamental plants in specialist succulent collections. The subfamily Didiereoideae is endemic to the southwest of Madagascar, where the species are characteristic elements of the spiny thickets.
The Polemoniaceae are a family of flowering plants consisting of about 25 genera with 270–400 species of annuals and perennials native to the Northern Hemisphere and South America, with the center of diversity in western North America.
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, and hosta, and the houseplants include snake plant, corn cane, spider plant, and plumosus fern.
Calceolariaceae is a family of flowering plants in the order Lamiales that has been recently segregated from Scrophulariaceae. The family includes three genera, Calceolaria, Porodittia, and Jovellana, but analysis suggests that the monotypic Porodittia should be placed within Calceolaria. Recent molecular phylogenies that included Calceolaria have shown not only that this genus does not belong in Scrophulariaceae but also that it is the sister clade to the majority of the other families of the Lamiales. Morphological and chemical characters also support the separation of Calceolariaceae from Scrophulariaceae and other Lamiales. Some recent studies have supported a sister-group relationship between Calceolariaceae and Gesneriaceae. Given this close relationship, some authors opt to merge this family into Gesneriaceae as subfamily Calceolarioideae
Gracillariidae is an important family of insects in the order Lepidoptera and the principal family of leaf miners that includes several economic, horticultural or recently invasive pest species such as the horse-chestnut leaf miner, Cameraria ohridella.
Tillandsioideae is a subfamily of plants in the bromeliad family Bromeliaceae. This subfamily contains the greatest number of species. 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.
