Ornithogalethumb|250px|Ornithogalum dubium Ornithogalum est un genre de plantes monocotylédones, les ornithogales. Il appartient à la famille des Liliaceae selon la classification classique. La le place dans la famille des Asparagaceae. Ce sont des plantes vivaces par leur bulbe, à feuilles basales, dont l'inflorescence se présente sous forme de racème ou de corymbe. Les fleurs sont étoilées, blanches ou verdâtres, à six tépales identiques (trois pétales et trois sépales pétaloïdes) et à six étamines.
GriffineaeThe tribe Griffineae (in the family Amaryllidaceae, subfamily Amaryllidoideae) includes 2 genera with 22 species from South America which are actually endemic to Brazil. A typical character of the representatives of the tribe are the flowers - They are with blue or lilac color 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 family Amaryllidaceae. The plants in this group are typical perennial flowers which are producing bulbs.
HippeastrumHippeastrum (les hippéastres) est un genre botanique d'environ 80 espèces de plantes à bulbes natives des régions tropicales et subtropicales d'Amérique centrale et d'Amérique du Sud (du nord de l'Argentine au Mexique et dans les Caraïbes). Il appartient à la famille des Liliaceae selon la classification classique. La classification phylogénétique le place dans la famille des Amaryllidaceae.
Lilioid monocotsLilioid monocots (lilioids, liliid monocots, petaloid monocots, petaloid lilioid monocots) is an informal name used for a grade (grouping of taxa with common characteristics) of five monocot orders (Petrosaviales, Dioscoreales, Pandanales, Liliales and Asparagales) in which the majority of species have flowers with relatively large, coloured tepals. This characteristic is similar to that found in lilies ("lily-like"). Petaloid monocots refers to the flowers having tepals which all resemble petals (petaloid).
AmaryllidoideaeLes Amaryllidoideae sont une sous-famille de plantes monocotylédones de la famille des Amaryllidaceae et de l'ordre des Asparagales. La plus récente classification botanique de l'Angiosperm Phylogeny Group, l'APG III, considère les Amaryllidaceae dans une vision élargie, avec trois sous-familles, dont l'une, les Amaryllidoideae correspond à l'ancienne famille des Amaryllidaceae, et les autres sont les Allioideae (ancienne famille des Alliaceae) et les Agapanthoideae (ancienne famille des Agapanthaceae).
BrodiaeoideaeBrodiaeoideae are a monocot subfamily of flowering plants in the family Asparagaceae, order Asparagales. They have been treated as a separate family, Themidaceae. They are native to Central America and western North America, from British Columbia to Guatemala. The name of the subfamily is based on the type genus Brodiaea. In molecular phylogenetic analyses, Brodiaeoideae is strongly supported as monophyletic. It is probably sister to Scilloideae. Recent treatments have divided Brodiaeoideae (or Themidaceae) into 12 genera.
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.
ScilloideaeScilloideae (named after the genus Scilla, "squill") is a subfamily of bulbous plants within the family Asparagaceae. Scilloideae is sometimes treated as a separate family Hyacinthaceae, named after the genus Hyacinthus. Scilloideae or Hyacinthaceae include many familiar garden plants such as Hyacinthus (hyacinths), Hyacinthoides (bluebells), Muscari (grape hyacinths) and Scilla and Puschkinia (squills or scillas). Some are important as cut flowers. Scilloideae are distributed mostly in Mediterranean climates, including South Africa, Central Asia and South America.
AsparagalesLes Asparagales sont un ordre de plantes monocotylédones introduit par la classification phylogénétique des angiospermes. Il regroupe des familles dont beaucoup faisaient partie de l'ordre des Liliales ou résultent de l'éclatement de la famille des Liliacées. [[File:Hippeastrum-seeds.jpg|thumb | Graines dHippeastrum à pelage foncé contenant du phytomélane]] Bien que la plupart des espèces de l'ordre soient herbacées, certaines ne dépassant pas 15 cm de haut, il existe un certain nombre de plantes grimpantes (par exemple, certaines espèces dAsparagus), ainsi que plusieurs genres formant des arbres (par exemple, Agave, Cordyline, Yucca, Dracaena, Aloe), qui peut dépasser 10 m de hauteur.
Classification de DahlgrenOne of the modern systems of plant taxonomy, the Dahlgren system was published by monocot specialist Rolf Dahlgren in 1975 and revised in 1977, and 1980. However, he is best known for his two treatises on monocotyledons in 1982 and revised in 1985. His wife Gertrud Dahlgren continued the work after his death. Dahlgren ranked the dicotyledons and monocotyledons as subclasses of the class of flowering plants (angiosperms) and further divided them into superorders.
