Asparagales subfamilies

Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales. It has previously been treated as a separate family, Agavaceae, and by 2020, several sources had restored the taxonomic status of Agavaceae as an independent family.

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.

Epidendroideae is a subfamily of plants in the orchid family, Orchidaceae. Epidendroideae is larger than all the other orchid subfamilies together, comprising more than 15,000 species in 576 genera. Most epidendroid orchids are tropical epiphytes, typically with pseudobulbs. There are, however, some terrestrials such as Epipactis and even a few myco-heterotrophs, which are parasitic upon mycorrhizal fungi.

Cypripedioideae is a subfamily of orchids commonly known as '''lady's slipper orchids, lady slipper orchids or slipper orchids'. Cypripedioideae includes the genera Cypripedium, Mexipedium, Paphiopedilum, Phragmipedium and Selenipedium''. They are characterised by the slipper-shaped pouches (modified labella) of the flowers – the pouch traps insects so they are forced to climb up past the staminode, behind which they collect or deposit pollinia, thus fertilizing the flower. There are approximately 165 species in the subfamily.

The Orchidoideae, or the orchidoid orchids, are a subfamily of the orchid family (Orchidaceae) that contains around 3630 species. Species typically have a single (monandrous), fertile anther which is erect and basitonic.

Asphodeloideae is a subfamily of the monocot family Asphodelaceae in the order Asparagales. It has previously been treated as a separate family, Asphodelaceae sensu stricto. The family Asphodelaceae has now been proposed to be a nomen conservandum, and the proposal has been recommended for ratification in 2017. In that case, Asphodelaceae will have priority over Xanthorrhoeaceae. This is reflected in the APG IV family lists.

Convallarioideae is a monocot subfamily of the family Asparagaceae. It used to be treated as a separate family, Ruscaceae s.l., but this family was merged into Asparagaceae in the APG III system of 2009. Initially the name Nolinoideae was used, derived from the type genus Nolina. This name was supposed to have been published by Burnett in 1935. However, this has been shown to be an error, as Burnett based a subfamily on the Solanaceae genus Nolana not Nolina.

Scilloideae (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.

The subfamily Apostasioideae is one of five subfamilies recognised within the orchid family, Orchidaceae. Compared to the other orchid subfamilies, it is relatively species-poor, with only two genera (Neuwiedia and Apostasia) and 15 species.

Vanilloideae is one of the subfamilies of orchids belonging to the large family Orchidaceae.

Amaryllidoideae ('Amaryllidaceae s.s., amaryllids') is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG IV, takes a broad view of the Amaryllidaceae, which then has three subfamilies, one of which is Amaryllidoideae (the old family Amaryllidaceae), and the others are Allioideae (the old family Alliaceae) and Agapanthoideae (the old family Agapanthaceae). The subfamily consists of about seventy genera, with over eight hundred species, and a worldwide distribution.

Asparagoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales, according to the APG III system of 2009. The subfamily name is derived from the generic name of the type genus, Asparagus. The group has previously been treated as a separate family Asparagaceae sensu stricto.

Lomandroideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales, according to the APG III system of 2009. The subfamily name is derived from the generic name of the type genus, Lomandra. The group has previously been treated as a separate family Laxmanniaceae. In the Kubitzki system, it is treated as Lomandraceae Lotsy.

Brodiaeoideae 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.

Hemerocallidoideae is 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).

Crocoideae is one of the major subfamilies in the family Iridaceae.

Iridoideae is one of the two main subfamilies in the popular family Iridaceae. It contains the best-known genus - Iris. The members of this subfamily are widely distributed worldwide. They grow in all continents except Antarctica. left|thumb|Iris milesii

Agapanthoideae is a monotypic subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. It is one of three subfamilies of Amaryllidaceae. It was formerly treated as a separate family, Agapanthaceae. The subfamily name is derived from the generic name of the type genus, Agapanthus.

Nivenioideae is a subfamily of flowering plants and one of the six subfamilies in the family Iridaceae. It contains three genera, from South Africa which are the only true shrubs in the family (Klattia, Nivenia and Witsenia), It previously included Aristea, Patersonia and also Geosiris, which are now each placed in their own monotypic subfamily.
