The Lilioideae are a subfamily of monocotyledonous perennial, herbaceous mainly bulbous flowering plants in the lily family, Liliaceae. They are found predominantly in the temperate and colder regions of the Northern Hemisphere, particularly East Asia and North America. The subfamily includes two tribes. They are of economic importance, particularly the lilies and tulips.

Description

Lilioideae genera are relatively homogeneous and distinct from the other two Liliaceae subfamilies (Calochortoideae and Streptopoideae). They are perennial herbaceous flowering plants that are mainly bulbous (Lilieae) with contractile roots, but may be rhizomatous (Medeoleae). Stems unbranched, leaves with parallel venation. Flowers are large and showy. The embryo sac (megagametophyte) is of the Fritillaria-type (tetrasporic). Capsule septicidal, seeds often flattened, exotesta palisaded or lignified. The seeds of Medeoleae are striate. [2] Chromosome number may be 7 (Medeoleae), [3] 9, or 11–14, with a highly variable length (2.2 - 27 µm).

Taxonomy

The term was introduced by Amos Eaton in his Botanical Dictionary in 1836. [4] Engler and Prantl included it as one of the eleven subfamilies of Liliaceae. [5] In 1927, Buxbaum's treatment of the subfamily included three tribes; Lloydieae ( Gagea , Lloydia and Szechenya and Giradiella — both now included in Lloydia), Tulipeae: ( Erythronium , Tulipa and Eduardoregalia — now part of Tulipa) and Lilieae ( Korolkowia , Fritillaria , Notholirion , Cardiocrinum , Nomocharis and Lilium ). [6] [7]

In the phylogenetic era, the subfamily Lilioideae has been circumscribed in both a broad ( sensu lato , or s.l.) and narrow (sensu stricto, or s.s.) sense. Tamura, [8] and others [9] have defined Lilioideae s.s. (or sensu Tamura) to include only the tribes Tulipeae and Lilieae. However other authorities including the Angiosperm Phylogeny Website (APWeb) [10] define Lilioideae s.l. to also include the Medeoleae (while subsuming the Tulipae into Lilieae). In the s.s. usage, the Medeoleae are treated as a separate subfamily, the Medeoloideae.

Genera

The subfamily Lilioideae includes ten genera and about 535 species. The largest genera are Gagea (200), Fritillaria (130), Lilium (110), and Tulipa (75 species).

<span class="mw-page-title-main">Asparagales</span> Order of monocot flowering plants

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.

<span class="mw-page-title-main">Liliales</span> Order of monocot flowering plants, including lilies

Liliales is an order of monocotyledonous flowering plants in the Angiosperm Phylogeny Group and Angiosperm Phylogeny Web system, within the lilioid monocots. This order of necessity includes the family Liliaceae. The APG III system (2009) places this order in the monocot clade. In APG III, the family Luzuriagaceae is combined with the family Alstroemeriaceae and the family Petermanniaceae is recognized. Both the order Lililiales and the family Liliaceae have had a widely disputed history, with the circumscription varying greatly from one taxonomist to another. Previous members of this order, which at one stage included most monocots with conspicuous tepals and lacking starch in the endosperm are now distributed over three orders, Liliales, Dioscoreales and Asparagales, using predominantly molecular phylogenetics. The newly delimited Liliales is monophyletic, with ten families. Well known plants from the order include Lilium (lily), tulip, the North American wildflower Trillium, and greenbrier.

<i>Fritillaria</i> Genus of flowering plants in family Liliaceae

Fritillaria (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. They are known for their large genome size and genetically are very closely related to lilies. They are native to the temperate regions of the Northern hemisphere, from the Mediterranean and North Africa through Eurasia and southwest Asia to western North America. Many are endangered due to enthusiastic picking.

<span class="mw-page-title-main">Liliaceae</span> Family of flowering plants in order Liliales, including lilies

The lily family, Liliaceae, consists of about 15 genera and 610 species of flowering plants within the order Liliales. They are monocotyledonous, perennial, herbaceous, often bulbous geophytes. Plants in this family have evolved with a fair amount of morphological diversity despite genetic similarity. Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals arranged in two whorls, six stamens and a superior ovary. The leaves are linear in shape, with their veins usually arranged parallel to the edges, single and arranged alternating on the stem, or in a rosette at the base. Most species are grown from bulbs, although some have rhizomes. First described in 1789, the lily family became a paraphyletic "catch-all" (wastebasket) group of lilioid monocots that did not fit into other families and included a great number of genera now included in other families and in some cases in other orders. Consequently, many sources and descriptions labelled "Liliaceae" deal with the broader sense of the family.

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).

The Lloydieae were a tribe of monocotyledon perennial, herbaceous mainly bulbous flowering plants in the Liliaceae (Lily) family. The tribe was generally considered monogeric, being represented by the single genus Lloydia. But since that genus has at various times and is now considered to be part of the genus Gagea, and therefore in the tribe Lilieae, it was sometimes listed with both genera. Furthermore, many authorities place Gagea into a separate tribe, Tulipeae. It has also historically been considered to be a subtribe of the Lilieae. In 2013, Kim et al. proposed splitting off Gagea from the rest of Tulipeae by resurrecting the tribe Lloydieae.

<span class="mw-page-title-main">Taxonomy of Liliaceae</span> Classification of the lily family Liliaceae

The taxonomy of the plant family Liliaceae has had a complex history since its first description in the mid-eighteenth century. Originally, the Liliaceae were defined as having a "calix" (perianth) of six equal-coloured parts, six stamens, a single style, and a superior, three-chambered (trilocular) ovary turning into a capsule fruit at maturity. The taxonomic circumscription of the family Liliaceae progressively expanded until it became the largest plant family and also extremely diverse, being somewhat arbitrarily defined as all species of plants with six tepals and a superior ovary. It eventually came to encompass about 300 genera and 4,500 species, and was thus a "catch-all" and hence paraphyletic. Only since the more modern taxonomic systems developed by the Angiosperm Phylogeny Group (APG) and based on phylogenetic principles, has it been possible to identify the many separate taxonomic groupings within the original family and redistribute them, leaving a relatively small core as the modern family Liliaceae, with fifteen genera and 600 species.

<span class="mw-page-title-main">Coronariae</span> Historical term for group of flowering plants, including lilies

Coronariae is a term used historically to refer to a group of flowering plants, generally including the lilies (Liliaceae), and later replaced by the order Liliales. First used in the 17th century by John Ray, it referred to flowers used to insert in garlands. Coronariae soon came to be associated with Liliaceae in the Linnaean system. The term was abandoned at the end of the 19th century, being replaced with Liliiflorae and then Liliales.
