Hippeastrum is a genus of about 90 species, and over 600 hybrids and cultivars, of perennial, herbaceous and bulbous plants, native to tropical and subtropical regions of the Americas, from Mexico south to Argentina and on some islands in the Caribbean. The majority have large, fleshy bulbs—usually about the size of a softball—and tall, broad, strap-like leaves that are (generally) evergreen, and large red or purple flowers. Numerous colors and cultivars have been created over the past hundred years.
Eucrosia is a genus of herbaceous, perennial and bulbous plants in the Amaryllis family distributed from Ecuador to Peru. The name is derived from the Greek eu, beautiful, and krossos, a fringe, referring to the long stamens. As circumscribed in 2020, the genus contains six species. Phaedranassa and Rauhia are the genera most closely related to Eucrosia.
Pamianthe is a genus of South American bulbous perennials in the Amaryllis family, subfamily Amaryllidoideae. They can be found in sandy, but rocky areas in Colombia, Ecuador, Peru, and Bolivia.
Ismene, or Peruvian daffodil, is a genus of South American plants in the Amaryllis family. The species are native to Peru and Ecuador and widely cultivated elsewhere as ornamentals because of their large, showy flowers.
Rhodolirium is a small South American genus in the tribe Hippeastreae of the family Amaryllidaceae. Although originally described by Philippi in 1858 it has long remained buried in other taxa, principally Hippeastrum and more recently Rhodophiala. Only in recent years has it been rehabilitated.
Griffinia is a genus of Brazilian plants in the Amaryllis family, subfamily Amaryllidoideae. It includes 23 known species which are endemic to Brazil. The most closely related genus to it is the monotypic Worsleya.
Griffinia hyacinthina is a bulbous species of flowering plant which is endemic to Brazil.
Chlidanthus is a genus of flowering plants in the family Amaryllidaceae native to Argentina, Bolivia, and Peru.
Alan W. Meerow is an American botanist, born in New York City in 1952. He specializes in the taxonomy of the family Amaryllidaceae and the horticulture of palms and tropical ornamental plants. He also works on the population genetics and molecular systematics of cycads and palms.
Pyrolirion, commonly known as fire lilies or flame lilies, is a small genus of herbaceous, bulb-forming South American plants in the Amaryllis family, native to Chile, Peru, and Bolivia.
Stenomesson is a genus of bulbous plants in the family Amaryllidaceae. All the species are native to western South America.
Phycella is a genus of herbaceous, perennial bulbous flowering plants belonging to the family Amaryllidaceae, subfamily Amaryllidoideae. The genus consists of five species distributed from central Chile to northwestern Argentina.
Paramongaia is a genus of South American plants in the Narcissus Family ( Amaryllidaceae), the most important species being Paramongaia weberbaueri found only in the Andes of Peru and Bolivia. Common names are "giant Peruvian daffodil." and Cojomaria. Its appearance resembles the "King Alfred" Daffodil, but the flower is up to 7.25 inches in length by 7.5 inches wide with a corona 3.3 inches by 3 inches long by three inches wide.
Urceolina is a genus of South American plants in the amaryllis family native to Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Guatemala, Panama, and Peru. It has also been introduced to many South and Central American states, as well as India and Sri Lanka. The formerly accepted genera Eucharis and Caliphruria are now regarded as synonyms of this genus. Many species of this genus share the common name Amazon lily.
Leptochiton is a genus of South American plants in the Amaryllis family.
Clinantheae is a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was described in 2000 by Alan Meerow et al. as a result of a molecular phylogenetic study of the American Amaryllidoideae. This demonstrated that the tribe Stenomesseae, including the type genus Stenomesson was polyphyletic. Part of the tribe segregated with the Eucharideae and were submerged into it, while the other part formed a unique subclade. Since the type species of Stenomesson was not part of the second subclade, it was necessary to form a new name for the remaining species together with the other genera that remained. This was Clinanthus, the oldest name for these species, and consequently the tribe Clinantheae.
Clinanthus elwesii is a species of plant in the family Amaryllidaceae. It is native to Peru. John Gilbert Baker, the English botanist who first formally described the species using the synonymous name Callithauma viridiflorum var. elwesii, named it in after Henry John Elwes, another English botanist who grew the specimen Baker examined.
Stenomesson leucanthum is a species of flowering plant in the family Amaryllidaceae. It is native to Peru. Pierfelice Ravenna, the Chilean botanists who first formally described the species, using the basionym Pucara leucantha, named it after its white flowers.
Clinanthus humilis is a species of flowering plant in the family Amaryllidaceae. It is a perennial herb native to Peru, Bolivia, northern Chile and north-western Argentina.
