The Faboideae are a subfamily of the flowering plant family Fabaceae or Leguminosae. An acceptable alternative name for the subfamily is Papilionoideae, or Papilionaceae when this group of plants is treated as a family.
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.
The Asclepiadoideae are a subfamily of plants in the family Apocynaceae. Formerly, they were treated as a separate family under the name Asclepiadaceae, e.g. by APG II, and known as the milkweed family.
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales.
Lotus, a latinization of Greek lōtos, is a genus of flowering plants that includes most bird's-foot trefoils and deervetches and contains many dozens of species distributed worldwide. Depending on the taxonomic authority, roughly between 70 and 150 are accepted. Lotus is a genus of legumes and its members are adapted to a wide range of habitats, from coastal environments to high altitudes.
Hydatellaceae are a family of small, aquatic flowering plants. The family consists of tiny, relatively simple plants occurring in Australasia and India. It was formerly considered to be related to the grasses and sedges, but has been reassigned to the order Nymphaeales as a result of DNA and morphological analyses showing that it represents one of the earliest groups to split off in flowering-plant phylogeny, rather than having a close relationship to monocots, which it bears a superficial resemblance to due to convergent evolution. The family includes only the genus Trithuria, which has at least 13 species, although species diversity in the family has probably been substantially underestimated.
The tribe Loteae is a subdivision of the plant family Fabaceae, in the Robinioids. These genera are recognized by the USDA:
The Molluginaceae are a family of flowering plants recognized by several taxonomists. It was previously included in the larger family Aizoaceae. The APG III system of 2009 made no change in the status of the family as compared to the APG II system of 2003 and the APG system of 1998, apart from a reassignment of several genera, such as the placement of Corrigiola and Telephium into Caryophyllaceae, Corbichonia in Lophiocarpaceae, Microtea into Microteaceae and Limeum in Limeaceae, because the family was found to be widely polyphyletic in Caryophyllales. In addition Macarthuria was found not to be related to Limeum as previously thought and thus it was placed in Macarthuriaceae, and similarly species formerly placed in Hypertelis, apart from type species Hypertelis spergulacea, a true Molluginaceae, were found to belong elsewhere and were described as Kewa in the family Kewaceae, named for the Royal Botanic Gardens Kew. Molluginaceae is still assigned to the order Caryophyllales in the clade core eudicots, although the generic circumscription is difficult because Mollugo is not monophyletic.
Trithuria is a genus of small ephemeral aquatic herb that represent the only members of the family Hydatellaceae found in India, Australia, and New Zealand. All of the 13 formally characterized species of Trithuria are found in Australia, with the exception of T. inconspicua and T. konkanensis, which are found in New Zealand and India, respectively. Until DNA sequence data and a reinterpretation of morphology proved otherwise, these plants were believed to be monocots related to the grasses (Poaceae). They are unique in being the only plants besides two members of Triuridaceae in which the stamens are in the center of the flower while the pistils surround them; in Hydatellaceae the resulting 'flowers' may instead represent condensed inflorescences or non-flowers.
Aphanopetalum is a genus of twining shrubs or vines in the family Aphanopetalaceae which are endemic to Australia.
Tripodion is a genus of flowering plants in the legume family, Fabaceae. It belongs to the subfamily Faboideae.
Limeum is a genus of flowering plants. It includes 25 species.
The robinioids are one of the four major clades in subfamily Faboideae of the plant family Fabaceae (Leguminosae). It is composed of the traditional tribes Loteae, Sesbanieae and Robinieae. It is a large and important clade that is distributed in mostly temperate areas. Species in this clade share a unique determinate root nodule structure. The clade is predicted to have diverged from the other legume lineages 48.3±1.0 million years ago.
Hosackia is a genus of flowering plants in the family Fabaceae (legumes). It is native to western North America, from British Columbia in Canada to Mexico.
Ottleya is a genus of flowering plants in the family Fabaceae (legumes). It is native to the southwestern United States and to Mexico.
Syrmatium was a formerly accepted genus of flowering plants in the family Fabaceae (legumes), native to the southwestern United States. As of February 2021, it was considered a synonym of Acmispon by Plants of the World Online, and only Acmispon was recognized by the Jepson eFlora.
Lotus glaucus is a species of flowering plant in the family Fabaceae, native to Madeira and the Salvage Islands. It is a perennial herbaceous plant with leaves made up of five leaflets. Its flowers are usually orange on opening. Lotus tenellus is included in a more broadly circumscribed L. glaucus by some authors, which extends its distribution to the Canary Islands.
Lotus tenellus is a species of flowering plant in the family Fabaceae, native to the Canary Islands. Some authors have included L. tenellus in Lotus glaucus, a species found in Madeira and the Salvage Islands. L. leptophyllus may be treated as a synonym of L. tenellus or as a separate species. L. tenellus has yellow flowers, with usually no more than three flowers in each flower head (umbel). Its leaves are made up of five leaflets.
Alice Maria Ottley (1882–1971) was a botanist, author, assistant professor and curator of the herbarium at Wellesley College. She collected and studied American flora, particularly species of Lotus, and publishing books and articles on botany.
