Asparagales is an order of plants in modern classification systems such as the Angiosperm Phylogeny Group (APG) and the Angiosperm Phylogeny Web. The order takes its name from the type family Asparagaceae and is placed in the monocots amongst the lilioid monocots. The order has only recently been recognized in classification systems. It was first put forward by Huber in 1977 and later taken up in the Dahlgren system of 1985 and then the APG in 1998, 2003 and 2009. Before this, many of its families were assigned to the old order Liliales, a very large order containing almost all monocots with colorful tepals and lacking starch in their endosperm. DNA sequence analysis indicated that many of the taxa previously included in Liliales should actually be redistributed over three orders, Liliales, Asparagales, and Dioscoreales. The boundaries of the Asparagales and of its families have undergone a series of changes in recent years; future research may lead to further changes and ultimately greater stability. In the APG circumscription, Asparagales is the largest order of monocots with 14 families, 1,122 genera, and about 36,000 species.
Agapanthus is a genus of plants, the only one in the subfamily Agapanthoideae of the family Amaryllidaceae. The family is in the monocot order Asparagales. The name is derived from Greek: ἀγάπη, ἄνθος.
The flowering plant genus Ipheion belongs to Allioideae, a subfamily of the family Amaryllidaceae. The World Checklist of Selected Plant Families no longer recognize the genus, regarding it as a synonym of Tristagma, although The Plant List accepts two species.
Nothoscordum is a genus of New World plants in the onion tribe within the Amaryllis family. It is probably paraphyletic. The genus is native to North, Central and South America, though a few species have become naturalized in various parts of the Old World.
Leucocoryne(glory-of-the-sun) is a genus of bulbous perennials in the family Amaryllidaceae. The foliage of all species is long and narrow and has an onion-like scent. The blue, white or lilac flowers are held in umbels.
Hamilton Paul Traub was an American botanist. He specialized in the study of Amaryllidaceae. He also did horticultural studies on beans. dr Traub was one of the founding members of the American Amaryllis Society in 1933, and for a long time the editor of its annual publication, variously called Year Book, American Amaryllis Society, Herbertia and Plant Life. Amaryllis Year Book.
Rhodophiala was a genus of herbaceous, perennial and bulbous plants in the Amaryllis family. It consisted of about 30 South American species distributed in southern Brazil, Argentina, and, specially, in Chile. Most of the species are known colloquially as añañuca. It has now been submerged in Zephyranthes.
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.
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).
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.
Solaria is a genus of South American plants in the family Amaryllidaceae, subfamily Allioideae, tribe Gilliesieae, native to Chile and Argentina. Kew treats Solaria as a synonym of Gilliesia.
Zoellnerallium is a genus of perennial herbaceous geophytes in the flowering plant family Amaryllidaceae. It is native to Chile and Argentina. It is included in the tribe Gilliesieae, within the subfamily Allioideae. It is considered to be part of a group of four genera within Gilliesieae, referred to as Ipheieae nom. nud.. In 2014 it was proposed to create a new tribe Leucocorynae with six genera, including Zoellnerallium, by splitting Gilliesieae into two separate tribes.
Tulbaghieae is a tribe of plants belonging to the subfamily Allioideae of the Amaryllis family (Amaryllidaceae). It comprises two genera, Tulbaghia and Prototulbaghia, native to South Africa.
Gilliesieae is a tribe of herbaceous geophyte plants belonging to the subfamily Allioideae of the Amaryllis family (Amaryllidaceae). Described in 1826, it contains fifteen genera and about eighty species. It has been variously treated as a subfamily or tribe. It is native to the Southern United States, Central and South America, predominantly Chile. Of the three tribes of genera that make up the subfamily Allioideae, Gilliesieae is the largest and most variable. The tribe was divided into two tribes in 2014, Gilliesiae s.s. and Leucocoryneae, based on differences in floral symmetry and septal nectaries.
Beauverdia is a genus of South American plants in the onion subfamily within Amaryllis family, native to Brazil, Uruguay, and Argentina. The plants are bulb-forming perennial herbs.
Erinna is a genus of perennial herbaceous geophytes in the flowering plant family Amaryllidaceae. It is native to Chile, South America. It is included in the tribe Gilliesieae, within the subfamily Allioideae. The genus is monotypic, with a single species, Erinna gilliesioides. It is relatively rare.
Allioideae is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. It was formerly treated as a separate family, Alliaceae. The subfamily name is derived from the generic name of the type genus, Allium. It is composed of about 18 genera.
Allium is a genus of monocotyledonous flowering plants with hundreds of species, including the cultivated onion, garlic, scallion, shallot, leek, and chives. The generic name Allium is the Latin word for garlic, and the type species for the genus is Allium sativum which means "cultivated garlic".
Allium dregeanum is the sole known species of Allium endemic to sub-Saharan Africa. It has also been described as the only Allium species endemic to the Southern Hemisphere, though some descriptions of the genus also include Allium juncifolium (Chile) and Allium sellovianum (Brazil), which are much less studied than Allium dregeanum. The distribution of Allium dregeanum extends from the summer-rainfall region, into the winter-rainfall zone of South Africa. Since Allium species are almost exclusively found in the Northern Hemisphere, with major centers of diversity in Central Asia and western North America, the biogeographical history of Allium dregeanum is of interest.
The precise taxonomy of the genus Allium is still poorly understood with incorrect descriptions being widespread. With over 850 species distributed over the Northern hemisphere Allium is the sole genus in the Allieae, one of four tribes of subfamily Allioideae (Amaryllidaceae). New species continue to be described and Allium is both highly variable and one of the largest monocotyledonous genera, but the precise taxonomy of Allium is poorly understood, with incorrect descriptions being widespread. The difficulties arise from the fact that the genus displays considerable polymorphism and has adapted to a wide variety of habitats. Furthermore, traditional classications had been based on homoplasious characteristics. However, the genus has been shown to be monophyletic, containing three major clades, although some proposed subgenera are not. Some progress is being made using molecular phylogenetic methods, and the internal transcribed spacer (ITS) region, including the 5.8S rDNA and the two spacers ITS1 and ITS2, is one of the more commonly used markers in the study of the differentiation of the Allium species.
