Plocosperma is the sole genus in the Plocospermataceae, [2] a family of flowering plants. [1] The genus contains a single species, Plocosperma buxifolium.
The Santalales are an order of flowering plants in the dicotyledons. Well-known members of the Santalales include sandalwoods and the many species of mistletoes. The order has a cosmopolitan distribution, but is heavily concentrated in tropical and subtropical regions. It derives its name from its type genus, Santalum (sandalwood).
Ranunculales is an order of flowering plants. Of necessity it contains the family Ranunculaceae, the buttercup family, because the name of the order is based on the name of a genus in that family. Ranunculales belongs to a paraphyletic group known as the basal eudicots. It is the most basal clade in this group; in other words, it is sister to the remaining eudicots. Widely known members include poppies, barberries, hellebores, and buttercups.
Ceratophyllaceae is a cosmopolitan family of flowering plants including one living genus commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant family in the order Ceratophyllales. Species are commonly called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta.
The Buxales are a small order of eudicot flowering plants, recognized by the APG IV system of 2016. The order includes the family Buxaceae; the families Didymelaceae and Haptanthaceae may also be recognized or may be included in the Buxaceae. Many members of the order are evergreen shrubs or trees, although some are herbaceous perennials. They have separate "male" (staminate) and "female" (carpellate) flowers, mostly on the same plant. Some species are of economic importance either for the wood they produce or as ornamental plants.
The Loganiaceae are a family of flowering plants classified in order Gentianales. The family includes up to 13 genera, distributed around the world's tropics. There are not any great morphological characteristics to distinguish these taxa from others in the order Gentianales.
Gelsemiaceae is a family of flowering plants, belonging to the order Gentianales. The family contains only three genera: Gelsemium, Mostuea and Pteleocarpa. Gelsemium has three species, one native to Southeast Asia and southern China and two native to Central America, Mexico, and the southeastern United States. The eight species of Mostuea are native to tropical areas of South America, Africa, and Madagascar. The two genera were formerly classified in the family Loganiaceae. Pteleocarpa was originally placed in Boraginaceae or in its own family Pteleocarpaceae, but it is most closely related to Gelsemiaceae with which it shares significant characters.
Adoxaceae, commonly known as moschatel family, is a small family of flowering plants in the order Dipsacales, now consisting of five genera and about 150–200 species. They are characterised by opposite toothed leaves, small five- or, more rarely, four-petalled flowers in cymose inflorescences, and the fruit being a drupe. They are thus similar to many Cornaceae.
Lophopyxis is a genus of flowering plants and the sole genus of the family Lophopyxidaceae. The group consists of two species of tendrillate lianas. They are found in the Sunda Islands.
In the APG IV system (2016) for the classification of flowering plants, the name asterids denotes a clade. Asterids is the largest group of flowering plants, with more than 80,000 species, about a third of the total flowering plant species. Well-known plants in this clade include the common daisy, forget-me-nots, nightshades, the common sunflower, petunias, yacon, morning glory, lettuce, sweet potato, coffee, lavender, lilac, olive, jasmine, honeysuckle, ash tree, teak, snapdragon, sesame, psyllium, garden sage, blueberries, table herbs such as mint, basil, and rosemary, and rainforest trees such as Brazil nut.
Trimeniaceae is a family of flowering plants recognized by most taxonomists, at least for the past several decades. It is a small family of one genus, Trimenia, with eight known species of woody plants, bearing essential oils. The family is subtropical to tropical and found in Southeast Asia, eastern Australia and on several Pacific Islands.
Euptelea is a genus of two species of flowering plants in the monogeneric family Eupteleaceae. The genus is found from Assam east through China to Japan, and consists of shrubs or small trees:
Myrothamnus is a genus of flowering plants, consisting of two species of small xerophytic shrubs, in the southern parts of tropical Africa and in Madagascar. Myrothamnus is recognized as the only genus in the family Myrothamnaceae.
Martyniaceae is a family of flowering plants in the Lamiales order that are restricted to the Americas. The family was included in Pedaliaceae in the Cronquist system but is recognized as a separate family by the Angiosperm Phylogeny Group on the basis of phylogenetic studies that show that the two families are not closely related. Both families are characterized by having mucilaginous hairs — which give the stems and leaves a slimy or clammy feel — and fruits with hooks or horns. Some members of the genus Proboscidea are known as "unicorn plant" or "devil's claw" because of their horned seed capsules.
Plant taxonomy is the science that finds, identifies, describes, classifies, and names plants. It is one of the main branches of taxonomy.
Ixiolirion is a genus of flowering plants native to central and southwest Asia, first described as a genus in 1821. Recent classifications place the group in the monogeneric family Ixioliriaceae in the order Asparagales of the monocots. In earlier systems of classification, it was usually placed in the family Amaryllidaceae.
Lanaria is a monotypic genus of flowering plants containing a single species, Lanaria lanata, endemic to the southern coast of South Africa where it is associated with the fynbos belt. Lanaria lanata is commonly known as Cape edelweiss or lambtails. The genus is placed in the monotypic family Lanariaceae, a family only recently recognized by taxonomists. The APG IV system of 2016 does recognize this family.
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.
Oncotheca is a genus of tree endemic to New Caledonia. There are two species, Oncotheca balansae and Oncotheca humboldtiana.
Hydrostachys is a genus of about 22 species of flowering plants native to Madagascar and southern and central Africa. It is the only genus in the family Hydrostachyaceae. All species of Hydrostachys are aquatic, growing on rocks in fast-moving water. They have tuberous roots, usually pinnately compound leaves, and highly reduced flowers on dense spikes.
Guamatela is a genus of flowering plants in the order Crossosomatales. Guamatela is the only genus in the family Guamatelaceae. The genus comprises a single species, the type species, Guamatela tuerckheimii Donn.Sm., an evergreen shrub with a prostrate habit that is native to Mexico, Guatemala, and Honduras. The genus Guamatela had formerly been included in the family Rosaceae before the Angiosperm Phylogeny Group placed it in the Guamatelaceae in 2009.
