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.
The Griffineae is a tribe in the family Amaryllidaceae, subfamily Amaryllidoideae. It includes 3 genera with 22 species endemic to Brazil in South America. A typical character of the representatives of the tribe are the flowers - They are blue or lilac and collected into an umbel. Only the members of this tribe and the genus Lycoris are able to form flowers with such color in the whole subfamily Amaryllidoideae of Amaryllidaceae. The species in this group are typically perennial and produce bulbs. The leaves are green, with elliptical form in most of the cases but in some members, as in Worsleya, they are sword-shaped.
Urceolina amazonica, formerly known as Eucharis amazonica, is a species of flowering plant in the family Amaryllidaceae, native to Peru. It is cultivated as an ornamental in many countries and naturalized in Venezuela, Mexico, the West Indies, Ascension Island, Sri Lanka, Fiji, the Solomon Islands and the Society Islands. The English name Amazon lily is used for this species, but is also used for some other species of the genus Urceolina.
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.
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).
Stenomesson is a genus of bulbous plants in the family Amaryllidaceae. All the species are native to western South America.
Amaryllidoideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG III, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae, and the others are Allioideae and Agapanthoideae. The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution.
Hannonia is a genus of plants in the Amaryllis family. It contains only one known species, Hannonia hesperidum, endemic to Morocco and confined to Western Morocco, Promontory of Hercules. The specific epithet comes from Greek έσπερος, of evening, as the flowers open in the late afternoon.
Leptochiton is a genus of South American plants in the Amaryllis family.
Pancratieae are a small European tribe of subfamily Amaryllidoideae, consisting of two genera including the type genus, Pancratium.
Eustephieae is a flowering plant tribe in the family Amaryllidaceae, subfamily Amaryllidoideae. It forms part of the Andean clade, one of two clades in The Americas.
Stenomesseae was a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was originally described by Traub in his monograph on the Amaryllidaceae in 1963, as Stenomessae based on the type genus Stenomesson. In 1995 it was recognised that Eustephieae was a distinct group separate from the other Stenomesseae. Subsequently, the Müller-Doblies' (1996) divided tribe Eustephieae into two subtribes, Stenomessinae and Eustephiinae.
Eucharideae is a tribe of plants within the family Amaryllidaceae. It was augmented in 2000 by Meerow et al. following a molecular phylogenetic study that revealed that many elements of the tribe Stenomesseae segregated with it, rather than separately, and were subsequently submerged in it. Further revisions were made in 2020, when three genera were merged. It forms one of the tribes of the Andean subclade of the American clade of the subfamily.
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.
Hymenocallideae is a tribe, where it forms part of the Andean clade, one of two American clades. The tribe was originally recognised by both Meerow (1995) and the Muller-Doblies' (1996). Its phylogenetic position within the Amaryllidoideae was established by Meerow et al. in 2000, while in-depth infratribal relationships were established in 2002.
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.
Pamianthe peruviana, also known as the giant Peruvian daffodil, is a species of epiphytic plant native to seasonally dry areas of Peru and Bolivia.
