Geraniales is a small order of flowering plants, included within the rosid subclade of eudicots. The largest family in the order is Geraniaceae with over 800 species. In addition, the order includes the smaller Francoaceae with about 40 species. Most Geraniales are herbaceous, but there are also shrubs and small trees.
Nyssaceae is a family of flowering trees sometimes included in the dogwood family (Cornaceae). Nyssaceae is composed of 37 known species in the following five genera:
Petrosaviaceae is a family of flowering plants belonging to a monotypic order, Petrosaviales. Petrosaviales are monocots, and are grouped within the lilioid monocots. Petrosaviales is a very small order composed of one family, two genera and four species accepted in 2016. Some species are photosynthetic (Japonolirion) and others are rare, leafless, chlorophyllous, mycoheterotrophic plants (Petrosavia). The family is found in low-light montane rainforests in Japan, China, Southeast Asia and Borneo. They are characterised by having bracteate racemes, pedicellate flowers, six persistent tepals, septal nectaries, three almost-distinct carpels, simultaneous microsporogenesis, monosulcate pollen, and follicular fruit.
Colchicaceae is a family of flowering plants that includes 15 genera with a total of about 285 known species according to Christenhusz and Byng in 2016.
Dilleniaceae is a family of flowering plants with 11 genera and about 430 known species. Such a family has been universally recognized by taxonomists. It is known to gardeners for the genus Hibbertia, which contains many commercially valuable garden species.
Caryocaraceae is a small family of flowering plants consisting of two genera with 26 species. The family is native to tropical regions of Central and South America, as well as the West Indies.
The Achatocarpaceae are a family of woody flowering plants consisting of two genera and 11 known species, and has been recognized by most taxonomists. The family is found from the southwestern United States south to tropical and subtropical South America.
Philesiaceae is a family of flowering plants, including two genera, each with a single species. The members of the family are woody shrubs or vines endemic to southern Chile.
Tecophilaeaceae is a family of flowering plants, placed in the order Asparagales of the monocots. It consists of nine genera with a total of 27 species.
Phytolaccaceae is a family of flowering plants. Though almost universally recognized by taxonomists, its circumscription has varied. It is also known as the Pokeweed family.
Caryophyllales is a diverse and heterogeneous order of flowering plants that includes the cacti, carnations, amaranths, ice plants, beets, and many carnivorous plants. Many members are succulent, having fleshy stems or leaves. The betalain pigments are unique in plants of this order and occur in all its families with the exception of Caryophyllaceae and Molluginaceae.
The Neuradaceae are a family of flowering plant, comprising three genera — Grielum, Neurada and Neuradopsis — totalling ten known species.
The APG III system of flowering plant classification is the third version of a modern, mostly molecular-based, system of plant taxonomy being developed by the Angiosperm Phylogeny Group (APG). Published in 2009, it was superseded in 2016 by a further revision, the APG IV system.
Dr Maarten Joost Maria Christenhusz is a Dutch botanist, natural historian and photographer.
Limeum is a genus of flowering plants. It includes 25 species.
Kewa is a genus of flowering plants, consisting of eight species of succulent sub-woody plants, native to eastern and southern Africa, including Saint Helena and Madagascar. These are small shrubs or herbs that form cushions and have edible, acid-tasting leaves. Kewa is the only genus in the family Kewaceae.
Kewa acida is one of the eight species currently recognized in the genus Kewa, the sole genus in the family Kewaceae. It is a bushy grey-leaved annual or short-lived perennial plant, with white flowers, endemic to St Helena, where it has been called the "salad plant". It is regarded as Critically Endangered. The succulent leaves are high in Vitamin C and were used by sailors in the past as a scurvy preventative.
Hypertelis is a genus of flowering plants in the family Molluginaceae. Most of its former species have been transferred to the new genus Kewa, and the remaining species, Hypertelis spergulacea, may also need a different placement. Hypertelis spergulacea is a woody-based plant, up to 30 cm (1 ft) high, with whorled greyish green leaves. It is found on the border between Namibia and the Northern Cape province of South Africa.
Macarthuriaceae is a family of plants in the order Caryophyllales and consists of a single genus, Macarthuria.
