There are a few visible traits that can be linked to many of the families. Most Ericales species tend to have woody stems or branches, seed capsules, cellular endosperm and ladder-like vessel perforations.[12][13] Species in Cornales tend to have the same perforations, as well as anthers attached at their base, ring-like nectaries, and cymes, which are inflorescences with lateral stalks that terminate in a flower or another branch.[14]
Perennials and annuals, almost always herbaceous, with succulent stems. Several species are cultivated as ornamentals. Impatiens glandulifera has become invasive in Europe and North America.[22][25]
Evergreen and deciduous shrubs, trees and vines, along with rhizomatous herbaceous perennials. The fruits of some species are used in jams or alcoholic drinks. The trees are often grown as ornamentals.[8][39]
3 genera, mostly in tropical and subtropical lowlands[55][56]
Mostly evergreen trees and shrubs with clear sap and frequently black hardwood. Diospyros kaki and other fruit species called persimmons are widely grown.[9][57]
121 genera, found almost worldwide, mostly in temperate zones and the subtropics[61][62]
Deciduous and evergreen trees, vines, shrubs and herbaceous perennials, growing in soil, on flooded land, on rock and on other plants. The most important commercial crops are in Vaccinium, including blueberries and cranberries. Popular garden plants include Rhododendron.[39][61]
Spiny shrubs and trees with almost erect, outward-leaning branches. Fouquieria splendens (ocotillo) is a popular North American arid-garden plant.[22][63]
9 genera, with centers of diversity in temperate North America, mountainous Europe and East Asia[10][73]
Deciduous and evergreen shrubs, small trees, woody vines and herbaceous plants. Hydrangea macrophylla has been cultivated in Japan for millennia.[10][22]
Lecythis, from Greek for "oil pot", which the fruit resembles[77][78]
24 genera, scattered throughout the tropics.[77][79]
Shrubs and trees, sometimes up to 55 m (180 ft) high. Of various edible seeds and nuts, the most important commercially is the Brazil nut. Several species provide timber.[39][77]
27 genera, mostly in western North America[104][105]
Mostly herbaceous annuals and perennials, with some small trees and shrubs. Some species have been used as a soap substitute by Native Americans. Cantua buxifolia is the national flower of Peru.[22][106]
57 genera, in northern temperate and arctic zones, mainly[110][111]
Trees, shrubs, mangroves, vines and herbaceous plants. Many genera are cultivated as ornamentals, including Androsace (rock jasmine) and various plants called primroses.[57][112]
Carnivorous, usually herbaceous perennials with underground rhizomes. The tubes (modified leaves) attract, trap and digest tiny animals. Some of these plants are grown in bog gardens.[22][121]
^Since 2019, these two orders have increasingly been identified as a single clade, a group of plants more closely related to each other than to any outside the group.[3]
^The taxonomy (classification) in this list follows Plants of the World (2017)[4] and the fourth Angiosperm Phylogeny Group system.[1] Total counts of genera for each family come from Plants of the World Online.[5] (See the POWO license.) Extinct taxa are not included.
^Each family's formal name ends in the Latin suffix -aceae and is derived from the name of a genus that is or once was part of the family.[16]
^Some plants were named for naturalists (unless otherwise noted).
