Plants named in 1957

Canellales is the botanical name for an order of flowering plants, one of the four orders of the magnoliids. It is recognized by the most recent classification of flowering plants, the APG IV system. It is defined to contain two families: Canellaceae and Winteraceae, which comprise 136 species of fragrant trees and shrubs. The Canellaceae are found in tropical America and Africa, and the Winteraceae are part of the Antarctic flora (found in diverse parts of the southern hemisphere). Although the order was defined based on phylogenetic studies, a number of possible synapomorphies have been

Anredera cordifolia, commonly known as the Madeira vine or mignonette vine, is a South American species of ornamental succulent vine of the family Basellaceae. The combination of fleshy leaves and thick aerial tubers makes this a very heavy vine. It smothers trees and other vegetation it grows on and can easily break branches and bring down entire trees on its own. Other names include lamb's tail and potato vine.

Galium tricornutum is a species of flowering plant in the coffee family known by the common names rough corn bedstraw, roughfruit corn bedstraw, and corn cleavers. It is widespread across most of Europe plus northern Africa and southern Asia, from Norway, Portugal and Morocco to China. It is also naturalized in Australia, the Canary Islands, Mauritius, Madeira, Réunion, Brazil, Argentina, and scattered locales in North America (mostly California and Oregon). Galium tricornutum is an annual herb with trailing or climbing stems up to about 35 centimeters in length. It forms tangled masses or

Pilosocereus (from Latin, "hairy cereus") is a genus of cactus native to the Neotropics. Tree cactus is a common name for Pilosocereus species. The genus Pseudopilocereus is a synonym of this genus. For many years, the illegitimate name Pilocereus was used for this genus, although properly a synonym for Cephalocereus. The subdivision of the genus has varied very widely, resulting in very different numbers of species being accepted. The commonly cultivated Pilosocereus pachycladus (syn. Pilosocereus azureus) is a blue cactus with hairy areoles that emit golden spines.

Salix arbutifolia, synonym Chosenia arbutifolia, is a flowering plant in the family Salicaceae, native to Japan, Korea, northeastern China, Siberia and the Russian Far East. It has been treated as the sole member of genus Chosenia.

Aizoanthemum is a small genus of plant in the family Aizoaceae, native to southern Angola and western Namibia. It has only 5 species. Before being given their own genus, these species were considered a subgenus of Aizoon. The genus name comes from the Greek "anthemon" (flowering) and for the similarity to the genus Aizoon.

Aloe sinkatana is a small, stemless Aloe native to Sudan. The plant is sometimes confused for the more common, medicinal Aloe vera.

Yushania is a genus of bamboo in the grass family. Recent classification systems place Yushania in the tribe Arundinarieae. The species of Yushania are evergreen, spreading, thornless bamboos native to Himalayan, African, Chinese, and Southeast Asian mountains at moderate to high altitudes, up to 3000 m. Yushania contains species formerly classified as members of Arundinaria, as well as one species that is still considered to be a Sinarundinaria by some. Some species of Yushania are popular to cultivate.

Plagiochilaceae is a family of liverworts in the order Jungermanniales. There may be anywhere from 500 to 1300 species, most of them from the tropics, but the exact number is still under revision. The family also has a wide distribution in temperate and arctic areas.

Moringa stenopetala, commonly known as the African Moringa or cabbage tree, is a deciduous tree in the plant genus Moringa, native to Kenya and Ethiopia. A drought-resistant species, it is characterized by its bottle-shaped trunk, long twisted seed pods, and edible leaves likened to cabbage, from which its common name is derived. M. stenopetala is extirpated in the wild in Ethiopia, though still grown there as a crop on the terraces of the Ethiopian Highlands, mainly in the Konso region. Like its widely cultivated relative M. oleifera, Moringa stenopetala is a multipurpose tree: the leaves,

Ludwigia hyssopifolia, called seedbox and linear leaf water primrose, is a species of flowering plant in the genus Ludwigia, native to the New World Tropics and widely introduced to the rest of the world's tropics. A serious weed of rice paddies, a single plant can produce 250,000 seeds.

Astragalus agnicidus is a rare species of milkvetch known by the common name Humboldt County milkvetch. It is endemic to northern California, where it is known only from two populations in Humboldt County and one in Mendocino County.

Poljakov - Altay, Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan,

Anomochlooideae is a subfamily of the true grass family Poaceae. It is sister to all the other grasses. It includes perennial herbs that grow on the shaded floor of forests in the Neotropics. There are two genera, Anomochloa and Streptochaeta, each in its own tribe.

Yucca grandiflora Gentry is a plant in the family Asparagaceae, native to the Sierra Madre Occidental in the Mexican states of Chihuahua and Sonora. Common names include Sahualiqui and Large-flowered Yucca. The Pima Bajo peoples of the region sometimes eat the immature fruits. It has a wide range, although it has a very low population density where it occurs.

Drosera roraimae is a sundew native to Brazil, Guyana, and Venezuela. It was originally described as a variety of Drosera montana before being raised to species rank in 1957. The specific epithet roraimae refers to Mount Roraima, a tepui or table-top mountain, where the type specimen was collected.

Drosera meristocaulis is a perennial species in the carnivorous plant genus Drosera, the only member of the subgenus Meristocaulis. It is a small, rosette- and branched stem-forming sundew that has many morphological affinities to the Australian pygmy sundews. D. meristocaulis is wholly endemic to Pico da Neblina, an isolated mountain on the Brazil-Venezuela border.

Chimantaea is a genus of flowering plants in the family Asteraceae. This genus is endemic to the Pantepui, a biogeographic province on the Guiana Highlands in Venezuela, Guyana, and Brazil. The region is characterized by a pattern of about 50 tepuis, isolated tabletop mountains that arise from the sandstone plateau of the highlands. Tepuis are known for their biodiversity, especially their concentrations of endemic species, and most are still pristine, undisturbed ecosystems. The genus is almost entirely restricted to the Chimantá Massif, a complex of several of these tepuis in Bolívar,

Callitris monticola, commonly known as the steelhead or dwarf cypress (a name it shares with several other plants), is a species of conifer in the family Cupressaceae. It is found only in Australia, occurring in the states of Queensland and New South Wales and is considered vulnerable due to its restricted distribution.

Salvia dolomitica (the dolomite sage or Pilgrim's Rest pink sage) is a perennial shrub native to the Mpumalanga and Limpopo provinces of South Africa, typically growing at 900–1500 m elevation. Profusely covered with grey leaves, it grows to 2 m in height and width in the wild, with pale lilac flowers.

Passiflora arbelaezii is a species in the family Passifloraceae native to eastern Nicaragua and western Colombia. This species was named in honor of Enrique Pérez Arbeláez, the person who collected the type specimen. It was first formally described in 1957 by Antonio Lorenzo Uribe Uribe. Like Passiflora discophora and Passiflora tryphostemmatoides, this species is rather unusual within its genus, due to the specialised adhesive structures. Passiflora arbelaezii forms branched tendrils with terminal adhesive pads, which form after contact of the distal ends with the substrate. Proliferation of

Encephalartos tegulaneus, the Kenyan giant cycad, is a species of cycad endemic to Kenya. It occurs in Eastern Province near Embu, Kenya, and on the Matthews Range in Rift Valley Province, where it grows between 1,200–2,300 metres altitude. It was discovered in May 1954 by Joy Adamson, author of "Born Free".
