Magnoliopsida is the group of flowering plants traditionally classified as dicotyledons. The dicots produce a pair of seed leaves that push through the soil when they germinate as against the single leaf produced by monocots. About four fifths of the flowering plants are dicots, about 200,000 species, and they include oaks, potatoes, daisies, cabbages, roses, cacti, buttercups, chestnut trees, heathers, mints and beans.The dicots are listed under their family names.
This large family of plants comprises 250 genera and 2500 species. They are mostly tropical and typically have entire leaves arranged in opposite pairs. The bracts are often showy and colorful. The flowers mostly occur in spikes and each has 4 or 5 petals. They are often irregularly shaped, with one or more petal sometimes elongated into a protruding tongue.
This large family of mainly small, succulent plants comprises 130 genera and 1200 species which chiefly come from South Africa. To survive under difficult desert conditions they adopt different strategies. Some have fleshy leaves, others just a single pair of leaves and others bury their leaves in the sand with just the tips exposed. The flowers are often large and showy, coming in bright colours and resembling daisies.
This family of tropical and temperate herbaceous plants and shrubs comprises 65 genera and 850 species. The leaves are mostly entire, opposite or alternate, and the flowers occur singly or in spikes, heads or tassels.

This family of tropical trees, shrubs and climbers comprises 180 genera and 1500 species. The leaves are typically simple and entire and arranged in opposite pairs. The large flowers are regular with 4 or 5 petals, often forming a funnel or dish shape. Members of this family are much cultivated in the tropics and many are grown under glass in more temperate regions.
Small family of parasitic herbs of the tropics.
This family of trees and shrubs which are often prickly or climbing, comprises 55 genera and 700 species. The leaves are usually alternate and the flowers small, with parts in fives. Hedera helix, the European Ivy, has many garden cultivars and Fatsia japonica is much cultivated as a shrub for a shady spot. The roots of species of Panax are sources of the Chinese remedy, Ginseng.
This family of herbaceous plants or shrubs comprises 7 genera and 400 species. Many are twining climbers and they typically have simple, alternate, long-stalked leaves, often heart-shaped. The flowers come in many strange forms but are basically bell-shaped, some terminating in a lobe or long tail.
The Asclepiadaceae comprise about 250 genera and 2,000 species. The family members are mostly herbs and shrubs. A characteristic of the family is a white sap ("milk"). Many plants in the family lianous. Some are cactuslike succulents with reduced leaves.
The family Asteracea, or Compositae as it used to be called, comprises about 25,000 species which is more than any other family of flowering plants. The family is characterized by its intricate composite flower which consist of a large number of individual florets acting as one flower.
This family of perennial plants with watery stems comprises 5 genera and 900 species. The leaves are mostly large and asymmetrical with one side larger than the other, and often vividly colored. The flower stems grow from the leaf axils and often have much-branched inflorescences with separate male and female flowers. Begonias are much cultivated for their showy flowers.
This family of shrubs from northern temperate zones comprises 4 genera and 570 species. Members of the genus Berberis typically have simple, spiny leaves and prickly stems while members of the genus Mahonia have thornless stems and leaves pinnately divided into leaflets. Both have bunches of small yellow or orange flowers with parts in sixes, followed by berries. Many species are cultivated as shade-tolerant and undemanding shrubs.
This family of mostly tropical trees and shrubs, including a number of vigorous climbers, comprises 120 genera and 650 species. The leaves are generally compound and paired and the large, ornamental flowers are usually tubular, flaring out into gaping mouths. The trees are much planted in tropical countries as ornamentals, and some of the climbing species grown under glass in cooler regions.
This family of large tropical trees comprises 20 genera and 180 species, mostly originating from the Americas. The leaves are palmately divided and the flowers have 5 sepals and 5 petals. The seeds are often embedded in cottony hairs in a large capsule. Some species have trunks adapted for storing water and Adansonia digitata, the Baobab, is the best known of these.
Butterfly bushes.
This family of mainly evergreen shrubs, comprises 4 genera and 100 species. They are mostly tropical or temperate with small simple leaves. The small flowers grow in the leaf axils and have parts in sixes and are followed by small, fleshy fruits. Buxus sempervirens, the common Box, is much cultivated in temperate gardens to form neat hedges.

The Cannabaceae family includes Humulus and Cannabis. The links presented here in the taxonomic tree are educational and scientific in nature.
Biology of the plant family that includes gourds, pumpkins, cucumbers, melons, and squash.
Small family of parasitic herbs in the Rafflesiales.
Family of insectivorous plants comprising 4 genera and about 100 species. The largest genus, Drosera, are the Sundews which trap insects by means of sticky hairs on their leaves, which grow in rosettes. Drosophyllum is a monotypic genus and catches insects in a similar way. Aldrovanda is an aquatic genus comprising just one species. Dionaea is the Venus Fly Trap which catches insects by trapping them in its folded up leaves.
Also called Leguminosae, the legume family. One of the largest families of flowering plants. The family is usually divided into three sub-families that are sometimes recognised as three separate families: Papilionaceae, Caesalpiniaceae and Mimosaceae. The three subfamilies are generally identifiable by their flowers:Fabaceae or Papilionoideae - flowers zygomorphic (with bilateral symmetry) and papilionaceous (have banner, wing, and keel petals). Banner positioned outside wings; keel petals fused. Includes most important legume crops, including beans and peas.
Caesalpinioideae - flowers zygomorphic and may be papilionaceous. Banner positioned within wings; keel petals unfused. Includes Cercis (redbud).
Mimosoideae - flowers actinomorphic (with radial symmetry), usually borne in dense clusters and having showy stamens. Includes Acacia, Albizia, and Mimosa.
The taxonomy at dmoz.org treats these three as separate families and defines the Fabaceae narrowly - see the related links for the Caesalpiniaceae and Mimosaceae.
Witch-hazel family.
Loosestrife family.
Family of broad-leaved flowering plants that includes Acacia, Albizia, and Mimosa. Flowers are actinomorphic (with radial symmetry), usually borne in dense clusters and having showy stamens.Alternatively considered to be a subfamily of the legume family (Fabaceae) known as the Mimosoideae. The taxonomy at dmoz.org treats the three subfamilies of the Fabaceae as separate families.
Monogeneric family of parasitic herbs in the Rafflesiales.
Family of plants previously included in the family Aizoaceae.
Monimiaceae is a plant family which comprises about 200 species of shrubs and small trees in 18-25 genera. They are native to the southern hemisphere tropics and subtropics.
Family comprising about 40 genera and 1400 species of evergreen trees, shrubs and lianas. Includes the economically important edible fruit-bearing genera of Ficus, the fig, Morus, the mulberry and Artocarpus, the breadfruit and jackfruit.
The only genus in this family is Platanus, sycamore or plane-tree.
