AllioideaeAllioideae 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. The subfamily contains both well-known garden plants and weeds, such as Nothoscordum. When Linnaeus formerly described the type genus Allium in his Species Plantarum in 1753, thirty species had this name.
AsphodelaceaeAsphodelaceae is a family of flowering plants in the order Asparagales. Such a family has been recognized by most taxonomists, but the circumscription has varied widely. In its current circumscription in the APG IV system, it includes about 40 genera and 900 known species. The type genus is Asphodelus. The family has a wide but scattered distribution throughout the tropics and temperate zones. Many of the species are cultivated as ornamentals. A few are grown commercially for cut flowers.
Armen TakhtajanArmen Leonovich Takhtajan or Takhtajian (Արմեն Լեւոնի Թախտաջյան; Армен Леонович Тахтаджян; surname also transliterated Takhtadjan, Takhtadzhi︠a︡n or Takhtadzhian, pronounced takh-tuh-JAHN; 10 June 1910 – 13 November 2009), was a Soviet-Armenian botanist, one of the most important figures in 20th century plant evolution and systematics and biogeography. His other interests included morphology of flowering plants, paleobotany, and the flora of the Caucasus. He was one of the most influential taxonomists of the latter twentieth century.
Takhtajan systemA system of plant taxonomy, the Takhtajan system of plant classification was published by Armen Takhtajan, in several versions from the 1950s onwards. It is usually compared to the Cronquist system. It admits paraphyletic groups. The first classification was published in Russian in 1954,and came to the attention of the rest of the world after publication of an English translation in 1958 as Origin of Angiospermous Plants. Further versions appeared in 1959 (Die Evolution der Angiospermen) and 1966 (Sistema i filogeniia tsvetkovykh rastenii).
SepalA sepal (ˈsɛpəl,_ˈsiːpəl) is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom. The term sepalum was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the calyx (plural calyces), the outermost whorl of parts that form a flower. The word calyx was adopted from the Latin calyx, not to be confused with calix 'cup, goblet'.
Cronquist systemThe Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including The Evolution and Classification of Flowering Plants (1968; 2nd edition, 1988) and An Integrated System of Classification of Flowering Plants (1981) (see Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida (dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses.
Thorne systemA system of plant taxonomy, the Thorne system of plant classification was devised by the American botanist Robert F. Thorne (1920–2015) in 1968, and he continued to issue revisions over many years (1968–2007). Some versions of the system are available online. The Bioinformatics Working Group Center for the Study of Digital Libraries at Texas A&M University lists the March 1999 version (and other classification systems).
CrocusCrocus (ˈkroʊkəs; plural: crocuses or croci) is a genus of seasonal flowering plants in the family Iridaceae (iris family) comprising about 100 species of perennials growing from corms. They are low growing plants, whose flower stems remain underground, that bear relatively large white, yellow, orange or purple flowers and then become dormant after flowering. Many are cultivated for their flowers, appearing in autumn, winter, or spring. The flowers close at night and in overcast weather conditions.
HemerocallidoideaeHemerocallidoideae is the a subfamily of flowering plants, part of the family Asphodelaceae sensu lato in the monocot order Asparagales according to the APG system of 2016. Earlier classification systems treated the group as a separate family, the Hemerocallidaceae. The name is derived from the generic name of the type genus, Hemerocallis. The largest genera in the group are Dianella (with 20 species), Hemerocallis (15), and Caesia (11). In the 21st century, the group has had two basic forms, depending on whether Johnsonia and its relatives are included or not.
FritillariaFritillaria (fritillaries) is a genus of spring flowering herbaceous bulbous perennial plants in the lily family (Liliaceae). The type species, Fritillaria meleagris, was first described in Europe in 1571, while other species from the Middle East and Asia were also introduced to Europe at that time. The genus has about 130–140 species divided among eight subgenera. The flowers are usually solitary, nodding and bell-shaped with bulbs that have fleshy scales, resembling those of lilies.
