Anchietea is a genus of flowering plants in the violet family Violaceae, with six accepted species, found in tropical South America.
Lianas or reclining shrubs with oblong-lanceolate to ovate leaves. The flowers, which may be unisexual or bisexual, are in axillary racemoids or fascicles, with a white to orange corollas that are strongly zygomorphic (bilaterally symmetrical) with the long bottom petal weakly differentiated with a well exserted (projecting) spur. On the five stamens, the filaments are strongly connate (fused) with the two lowest anthers calcarate (spurred) and possessing a small dorsal connective appendage that is entire and ovate. In the gynoecium, the style is rostellate (beaked). The fruit is a very thin walled bladder-like capsule. There are many seeds per carpel, that are orbicular in outline and strongly flattened and encircled with a low interrupted ridge, or broad wing. [5] [6] [7] The genus is characterized by membranaceous inflated capsules that usually prematurely expose the strongly flattened seeds to maturation. [8]
The genus Anchietea was first described by Saint-Hilaire in 1824, with a single species Anchietea salutaris, which thus is considered the type species. [9] Therefore, the genus bears his name, A.St.-Hil., as the botanical authority. [4] Shortly before this, Martius had described a species in a related genera, Noisettia pyrifolia . [10] In 1831, Don transferred this species to Anchietea, noting that the specific epithet pyrifolia referred to "pear-shaped leaves". [11] [12] A revision of the genus in 2013 identified A. salutaris and A. pyrifolia as conspecific, and since A. pyrifolia had priority (as Noisettia pyrifolia) it is the type species. [12]
Early taxonomic schemes, primarily based on floral morphology, such as Bentham and Hooker (1862) [13] placed Anchietea within subfamily Violoideae, tribe Violeae, subtribe Violinae. [6] [14] Anchietea is one of four lianescent genera in Violaceae, together with Calyptrion Ging. , Agatea A.Gray and the more recently discovered (2003) Hybanthopsis Paula-Souza. [15] Historically, these genera were distributed among separate subtribes, with Anchietea within subtribe Violinae with Calyptrion and Hybanthopsis and Agatea in subtribe Hybanthinae. [5] [14]
Molecular phylogenetic studies have now grouped these four genera together into a single lianescent clade, one of four within the family Violaceae. [7]
The genus Anchietea is named for the sixteenth century Jesuit missionary and naturalist Joseph of Anchieta, who described the Brazilian flora. [11] [16]
Eight species are accepted. [2]
Estimates of the number of species in Anchietea has varied considerably between five [5] [17] and nine, [1] [2] but historically, the genus has been poorly described and new species have continued to be described. Paula-Souza and colleagues recognize six species, [18] [8] [7] having added A. ferrucciae in 2010 as a new description [8] and A. ballardii in 2016. [19] [20]
Extra-Amazonian South America, in the seasonally-dry tropical forests (SDTF) of South America. [19] [21] [2]
Viola is a genus of flowering plants in the violet family Violaceae. It is the largest genus in the family, containing over 680 species. Most species are found in the temperate Northern Hemisphere; however, some are also found in widely divergent areas such as Hawaii, Australasia, and the Andes.
The Salicaceae is the willow family of flowering plants. The traditional family included the willows, poplar, aspen, and cottonwoods. Genetic studies summarized by the Angiosperm Phylogeny Group (APG) have greatly expanded the circumscription of the family to contain 56 genera and about 1220 species, including the Scyphostegiaceae and many of the former Flacourtiaceae.
Violaceae is a family of flowering plants established in 1802, consisting of about 1000 species in about 25 genera. It takes its name from the genus Viola, the violets and pansies.
Carl Friedrich Philipp von Martius was a German botanist and explorer. Between 1817 and 1820, he travelled 10,000 km through Brazil while collecting botanical specimens. His most important work was a comprehensive flora of Brazil, Flora Brasiliensis, which he initiated in 1840 and was completed posthumously in 1906.
Augustin François César Prouvençal de Saint-Hilaire was French botanist and traveller who was born and died in Orléans, France. A keen observer, he is credited with important discoveries in botany, notably the direction of the radicle in the embryo sac and the double point of attachment of certain ovules. He also described two families, the Paronychiae and the Tamariscinae, as well as many genera and species.
Syagrus is a genus of Arecaceae (palms), native to South America, with one species endemic to the Lesser Antilles. The genus is closely related to the Cocos, or coconut genus, and many Syagrus species produce edible seeds similar to the coconut.
Desmoncus is a genus of mostly climbing, spiny palms native to the Neotropics. The genus extends from Mexico in the north to Brazil and Bolivia in the south, with two species present in the southeastern Caribbean.
Jean Henri Jaume Saint-Hilaire was a French naturalist and artist, born in Grasse, France.
Hybanthus (green-violet) is a genus of flowering plants in the family Violaceae. This genus name is Greek for "humpback flower", referring to the drooping pedicels of plants that are part of this genus. The genus is grossly polyphyletic and may contain up to nine different genera, of which Pombalia Vand., Cubelium Raf. and Pigea DC. have been previously recognised.
Philcoxia is a genus of seven rare plant species in the Plantaginaceae that are endemic to Brazil and resemble terrestrial species of the genus Utricularia. The genus, formally described in 2000, consists of the species P. bahiensis, P. goiasensis, P. minensis, P. tuberosa, P. rhizomatosa, P. maranhensis and P. courensis, each of the first three named for the Brazilian state to which it is endemic. The species are characterized by subterranean stems, peltate leaves at or below the soil surface, and five-lobed calyces. Their habitat has been reported as areas of white sand in the midst of cerrado vegetation at an elevation between 800 and 1450 m. Initial descriptions of the genus included suspicions that the plethora of stalked capitate glands on the upper surfaces of leaves was an indication that these species may be carnivorous. A study published in 2007 tested P. minensis for protease activity, a typical test for the carnivorous syndrome, and could detect none. Later studies detected other digestive enzymes such as phosphatases and qualitatively assessed prey digestion and nutrient uptake, suggesting that it is a true carnivorous plant. The genus epithet honors David Philcox (1926-2003), a botanist at Kew Gardens who worked extensively in tropical Scrophulariaceae.
The Amaryllidaceae are a family of herbaceous, mainly perennial and bulbous flowering plants in the monocot order Asparagales. The family takes its name from the genus Amaryllis and is commonly known as the amaryllis family. The leaves are usually linear, and the flowers are usually bisexual and symmetrical, arranged in umbels on the stem. The petals and sepals are undifferentiated as tepals, which may be fused at the base into a floral tube. Some also display a corona. Allyl sulfide compounds produce the characteristic odour of the onion subfamily (Allioideae).
Hippeastreae is a tribe of plants belonging to the subfamily Amaryllidoideae of the Amaryllis family (Amaryllidaceae). Species in this tribe are distributed in South America. Flowers are large and showy, zygomorphic, with the stamens in varying lengths, inflorescence bracts are often fused basally. The seeds are flattened, winged or D-shaped. Reported basic chromosome numbers are x= 8-13, 17, and higher. All the species in this tribe present a remarkable aesthetic interest and horticultural value.

Noisettia is a genus of flowering plants in the violet family Violaceae, with a single known species.
Calyptrion is a genus of flowering plants in the violet family Violaceae, with four known species.
