The Nymphaeales are an order of flowering plants, consisting of three families of aquatic plants, the Hydatellaceae, the Cabombaceae, and the Nymphaeaceae. It is one of the three orders of basal angiosperms, an early-diverging grade of flowering plants. At least 10 morphological characters unite the Nymphaeales. One of the traits is the absence of a vascular cambium, which is required to produce both xylem (wood) and phloem, which therefore are missing. Molecular synapomorphies are also known.
Ceratophyllum is a cosmopolitan genus of flowering plants including four accepted living species in 2016, commonly found in ponds, marshes, and quiet streams in tropical and in temperate regions. It is the only extant genus in the family Ceratophyllaceae, itself the only extant family in the order Ceratophyllales. They are usually called coontails or hornworts, although hornwort is also used for unrelated plants of the division Anthocerotophyta.
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
Melanthiaceae, also called the bunchflower family, is a family of flowering herbaceous perennial plants native to the Northern Hemisphere. Along with many other lilioid monocots, early authors considered members of this family to belong to the family Liliaceae, in part because both their sepals and petals closely resemble each other and are often large and showy like those of lilies, while some more recent taxonomists have placed them in a family Trilliaceae. The most authoritative modern treatment, however, the APG III system of 2009, places the family in the order Liliales, in the clade monocots. Circumscribed in this way, the family includes up to 17 genera.
Brodiaea, also known by the common name cluster-lilies, is a monocot genus of flowering plants.
The genus Muilla includes four to five species of flowering plants.
Brodiaeoideae are a monocot subfamily of flowering plants in the family Asparagaceae, order Asparagales. They have been treated as a separate family, Themidaceae. They are native to Central America and western North America, from British Columbia to Guatemala. The name of the subfamily is based on the type genus Brodiaea.
The common names soap plant, soaproot and amole refer to the genus Chlorogalum. They are native to western North America, with some species in Oregon but they are mostly found in California. Common names of the genus and several species derive from their use as soap.
Narthecium is a Eurasian and North American genus of herbaceous flowering plants. This genus was traditionally treated as belonging to the family Liliaceae, but the APG II system of 2003 placed it in the family Nartheciaceae.
Schisandraceae is a family of flowering plants with 3 known genera and a total of 92 known species. Such a family has been recognized by most taxonomists, at least for the past several decades. Before that, the plants concerned were assigned to family Magnoliaceae and Illiciaceae.
Mayaca is a genus of flowering plants, often placed in its own family, the Mayacaceae. In the APG II system of 2003, it is assigned to the order Poales in the clade commelinids. The Cronquist system, of 1981, also recognised such a family and placed it in the order Commelinales in the subclass Commelinidae.
Erythroxylaceae is a family of flowering trees and shrubs consisting of 4 genera and 271 species. The four genera are AneulophusBenth., ErythroxylumP.Browne, NectaropetalumEngl., and PinacopodiumExell & Mendonça. The best-known species are the coca plants, including the species Erythroxylum coca, the source of the substance coca.
Najas, the water-nymphs or naiads, is a genus of aquatic plants. It is cosmopolitan in distribution, first described for modern science by Linnaeus in 1753. Until 1997, it was rarely placed in the Hydrocharitaceae, and was often taken as constituting the family Najadaceae.
Hesperocallis is a genus of flowering plants that includes a single species, Hesperocallis undulata, known as the desert lily or ajo lily.
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.
James Lauritz Reveal was a U.S. botanist best known for his contributions to the genus Eriogonum and for his work on suprageneric names. His website, at PlantSystematics.org, also presents material on plant taxonomy including the Reveal system. He published extensively on North American flora, was a member of the Angiosperm Phylogeny Group, and was one of the authors of the APG II and APG III classifications.
Dipterostemon is a monotypic genus of flowering plants in the family Asparagaceae. Its only species is Dipterostemon capitatus, synonym Dichelostemma capitatum, known by the common names blue dicks, purplehead and brodiaea, native to the Western United States and northwest Mexico.
Dichelostemma congestum is a species of flowering plant known by the common name ookow or fork-toothed ookow. It is native to California, Oregon and Washington.
Dipentodontaceae is a family of flowering plants containing two genera.
- DipentodonDunn - southern China, Assam, Myanmar
- PerrottetiaKunth in F.W.H.von Humboldt - southern China, Southeast Asia, Papuasia, Queensland, Hawaii, Latin America.
Chaunochiton is a genus of flowering plants. In the APG IV system, the genus is placed in the family Olacaceae. Other sources place it in the segregate family Aptandraceae.
