Plants named in 2000

Liverworts are a group of non-vascular land plants forming the division Marchantiophyta ( ). They may also be referred to as hepatics. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. The division name was derived from the genus name Marchantia, named after his father by French botanist Jean Marchant. It is estimated that there are about 9000 species of liverwort. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a

Helotiales is an order of the class Leotiomycetes within the division Ascomycota. The taxonomy within Helotiales has been debated. It has expanded significantly as genomic techniques for taxonomical identification have become more commonly used. As of February 2020, the order is estimated to contain 30 accepted families, 519 genera, and 6266 species. Helotiales is the largest order of non-stromatic discomycetes that usually, but not always, have brightly coloured apothecia. Many members of the family have obviously cup-shaped ascomata with little or no stipes. They are usually found fruiting

Lessertia frutescens (syn. Sutherlandia frutescens (L.) R.Br.; Colutea frutescens L.) is a southern African legume in the family Fabaceae.

It is a shrub with bitter, aromatic leaves, with red-orange flowers appearing in spring to mid-summer. These are followed by inflated, air-filled pods containing the seeds.

Taxiphyllum barbieri, known as Java moss or Bogor moss, is a moss belonging to the family Hypnaceae. Native to Southeast Asia, it is commonly used in freshwater aquariums. It attaches to rocks, roots, and driftwood. In the wild, it grows in humid riparian areas. It was originally described as Isopterygium barbieri from Vinh, Vietnam.

Blasiales is an order of liverworts with a single living family and two species. The order has traditionally been classified among the Metzgeriales, but molecular cladistics suggests a placement at the base of the Marchantiopsida.

Xeronema is a genus of flowering plants containing two species, Xeronema moorei from New Caledonia, and Xeronema callistemon (the Poor Knights lily) from the Poor Knights Islands and Taranga Island in New Zealand.

Zea nicaraguensis is an annual, true grass species in the genus Zea. It is considered to be phenotypically the most distinctive, as well as the most threatened teosinte. This teosinte thrives in flooded conditions along 200 m of a coastal estuarine river in northwest Nicaragua at the Reserva Natural de Apacunca. Virtually all populations of teosinte are either threatened or endangered with Z. nicaraguensis being the most endangered, it survives as about 6000 plants in an area of 200 x 150 m. The Mexican and Nicaraguan governments have taken action in recent years to protect wild teosinte

Euphorbia ankazobensis is a species of plant in the family Euphorbiaceae. It is endemic to Madagascar. It is known from one single collection in the Ankazobe area of Madagascar's Central Highlands. Its natural habitat is in remnant montane forest. It is threatened by habitat loss, and its natural habitat is extremely fragmented and degraded by human activity. It is assessed as critically endangered. Trade in this species is regulated under Appendix II of CITES.

Cyanicula, commonly known as blue orchids, is a genus of twelve species of plants in the orchid family, Orchidaceae. All are endemic to Australia, eleven are endemic to Western Australia and one species occurs in eastern Australia. While both the common and scientific names refer to "blue", the two subspecies of C. ixioides have yellow or white flowers. They are similar to orchids in the genus Caladenia but differ in their flowers colour and in other important ways.

Cochemiea barbata is a small cactus native to Chihuahua, Sonora, and Durango, with the common name greenflower nipple cactus.

Saltugilia is a genus of flowering plants in the phlox family, Polemoniaceae. They are known commonly as woodland gilias. There are four species. Two are endemic to California in the United States, and the distributions of the other two extend into Baja California in Mexico. This genus was erected in the year 2000 to segregate three species from the genus Gilia on the basis of phylogenetic evidence. Analysis of DNA was used in the formation of the new taxon, and studies of other characteristics of the plants, such as morphological, palynological, and ecological traits, were considered.
