Liliales is an

monophyletic, with ten families. Well known plants from the order include Lilium (lily), tulip, the North American wildflower Trillium, and greenbrier
.

Thus circumscribed, this order consists mostly of

heterotrophic
.

The order has worldwide distribution. The larger families (with more than 100 species) are roughly confined to the Northern Hemisphere, or are distributed worldwide, centering on the north. On the other hand, the smaller families (with up to 10 species) are confined to the Southern Hemisphere, or sometimes just to Australia or South America. The total number of species in the order is now about 1768.

As with any herbaceous group, the fossil record of the Liliales is rather scarce. There are several species from the Eocene, such as Petermanniopsis anglesaensis or Smilax, but their identification is not definite. Another known fossil is Ripogonum scandens from the Miocene. Due to the scarcity of data, it seems impossible to determine precisely the age and the initial distribution of the order. It is assumed that the Liliales originate from the Lower Cretaceous, over 100 million years ago. Fossil aquatic plants from the Cretaceous of northeastern Brazil and a new terrestrial species placed in the new genus Cratosmilax suggest that the first species have appeared around 120 million years ago when the continents formed Pangea, before dispersing as Asia, Africa and America.[4] The initial diversification to the current families took place between 82 and 48 million years ago.[5] The order consists of 10 families, 67 genera and about 1,768 species.

History

Origins

The

Phanerogamicae or seed plants he called his class IV, or Ternariae. The latter, he divided into five orders (ordo), including the Liliaceae.[17]

A number of later

monocotyledons,[20] it was replaced by Liliiflorae and then Liliales in subsequent publications (see Table for history).[21]

Phyletic systems

Subsequent authors, now adopting a

Lotsy (1911),[25] and Wettstein in 1924, in class Monocotyledones, subdivision Angiospermae.[26]

Reveal (2007).[31]

superorder Lilianae, one of four within subclass Liliidae. Liliidae in turn was one of four subclasses in class Liliopsida (monocots).[32] In contrast Thorne and Reveal (2007) abandoned the use of monocotyledons as a distinct taxon, replacing it with 3 separate subclasses of Magnoliopsida (angiosperms), of which Liliidae consists of 3 superorders, placing Liliales in superorder Lilianae.[31]

In all these systems, Liliales (or Liliiflorae) were visualised as either a direct division of the monocots (or equivalent) or were placed in an intermediate division of the monocots, such as superorder Lilianae.[33]

Molecular phylogenetic systems

The development of

clades, which continued the use of Liliales as the name for the taxon.[39]

The Angiosperm Phylogeny Group APG system (1998) established a structure of monocot classification with ten orders.[37] Notable was the separation of asparagids, as suggested by Dahlgren,[10] into Asparagales, with other taxa placed in Dioscoreales, resulting in a much reduced order.[9][8]

Subdivision

The circumscription of Liliales has varied greatly since Perleb's original construction with 11 families in 1826.[8] Many of these families are now considered to be in Asparagales, with the remainder in commelinids and Dioscoreales, as shown in this table.

Treatment of families in modern taxonomy (APG), remaining families included in Liliales:

The availability of molecular phylogenetic methods suggested four main lineages within Liliales, and seven families;[8]

  1. Liliaceae group: Liliaceae (including some former
    Calochortaceae
    ), and Smilacaceae (including Ripogonaceae and Philesiaceae)
  2. Campynemataceae
  3. Colchicaceae group: Colchicaceae (including Petermannia and Uvularia), Alstroemeriaceae and Luzuriaga
  4. Melanthiaceae (including Trilliaceae)

The first Angiosperm Phylogeny Group classification (APG I) in 1998 had the following circumscription, with 9 families, having separated Philesiaceae and Ripogonaceae from Smilacaceae:[37]

The

APG IV (2016) left this unchanged, with 10 families.[38]

The exact phylogenetic relationship between the families of Liliales has been subject to revision. This cladogram shows that of the Angiosperm Phylogeny Website (2020):[47][11]

Melanthiaceae

branch with 50–80% support

The bulk of the Liliales species are found in the very diverse family Liliaceae (16 genera, 610 species). Of the remaining nine families, three are referred to as the vine families (Ripogonaceae, Philesiaceae and Smilacaceae) and form a cluster.[11]

Families

Corsia ornata

Corsiaceae

The Corsiaceae (ghost-flower family) are a very small family of 3

mycoheterotrophic genera, lacking chlorophyll, with 27 species of perennial herbaceous plants. They are found in montane forests in South America (one genus) and from southern China to northern Australia in areas with high rainfall, and among dense leaf litter. The majority of species occur in the type genus Corsia. The name commemorates the Florentine plant collector Marquis Bardo Corsi Salviati (1844–1907).[48][49]

Campynema lineare

Campynemataceae

The Campynemataceae (Green-mountainlily family) are a very small family of two genera and four species of rhizomatous herbaceous plants found in Tasmania and New Caledonia. The name is derived from the Greek words kampylos (curved) and nema (thread).[48][49]

Veratrum album

Melanthiaceae

The Melanthiaceae (Wake Robin family) is a family of perennial herbaceous plants, whose storage organs include bulbs, rhizomes and corms (rarely, e.g.

boreal Northern hemisphere, in the Americas extending south to the Andes and in Asia to the Himalayas and Taiwan. Melanthiaceae consists of 17 genera and 173 species distributed in a number of subdivisions. The largest genus is Trillium (44 species) but many genera are monotypic. A number of genera, including Trillium are used as garden ornamentals, especially for woodland gardens. Paris japonica is noted for having the largest genome known to date. The family name is derived from the Greek words melas (black) and anthos (flower) in reference to the dark colour of the petals. [48][49]

Petermannia cirrosa

Petermanniaceae

The Petermanniaceae (Petermann's vine family) consists of a single species, Petermannia cirrosa, a perennial woody vine with underground rhizomes. Petermannia is restricted to Queensland and New South Wales, in temperate rainforests between Brisbane and Sydney. The family was named for Wilhelm Ludwwig Petermann (1806–1855), director of the botanical garden at Leipzig.[48][49]

Colchicum autumnale flowers
Colchicum autumnale

Colchicaceae

The Colchicaceae (Naked-ladies or Colchicum family) are perennial erect and climbing plants with underground corms, tubers and rhizomes. They are herbaceous with the exception of Kuntheria which has a somewhat woody stem. Their distribution is widespread including in temperate zones in North America, Europe, North Africa and the Middle east and tropical zones in Africa, Asia and Australasia. They are absent from South America. The family is of medium size with 15 genera and about 285 species. The largest genus is the type genus, Colchicum, with 159spp. Although the alkaloids, which characterise them, they contain are toxic to animals and humans, Colchicine has usage medicinally and in botanical laboratories. They are also include popular garden and indoor ornamentals. These include Colchicum and Gloriosa. The family is named after Colchis on the eastern Black Sea.[48][49][9]

Alstroemeria pelegrina flower
Alstroemeria pelegrina

Alstroemeriaceae

The Alstroemeriaceae (Inca-lily family) are erect or creeping perennial (rarely annual) herbaceous plants with occasional shrubby vines, some of which have evergreen stems. They are occasionally epiphytic and form often swollen rhizomes. They are found in tropical and temperate Central and South America, as well as Australasia. There are two large genera (Alstroemerieae), the erect Alstroemeria (S America 125 spp.) and twining Bomarea (Central & S America 122 spp.) and two very small genera (Luzuriageae) with 2 and 4 species each, for a total of 253 species in the family. Two species are widely used for food in S America, Alstroemeria ligtu is used for a flour (Chuño) that is extracted from its roots, while the tubers of Bomarea edulis are directly consumed. Luzuriaga radicans, also from S America, produces fibre used in rope making. Alstroemeria cultivars are popular ornamentals and widely used as cut flowers (Peruvian lilies). The family is named for Baron Clas Alströmer (1736–1794), a student of Linnaeus.[48][49]

Developing inflorescence of Ripogonum scandens
Ripogonum scandens

Ripogonaceae

The Ripogonaceae (Supplejack family) is a very small family, with a single genus, Ripogonum and six species. They are woody evergreen shrubs and vines arising from a horizontal rhizome, swollen at its base to form a tuber. They are confined to Eastern Australasia, with the type species, Ripogonum scandens as the sole New Zealand species. The stems have a use in basketry and building and the young shoots are edible. The name is derived from two Greek words, ripos (wicker) and gony (node) in reference to their node bearing shoots.[48][49]

Philesia magellanica

Philesiaceae

The Philesiaceae (Chilean-bellflower family) are a very small family consisting of two monotypic genera, the two species being

national flower of Chile and a popular ornamental with edible fruit. The name is thought to be related to the Greek word phileo (love), because of the attractiveness of its flowers.[48]

Leaves and berries of Smilax aspera
Smilax aspera

Smilacaceae

The Smilacaceae (Catbrier family) consist of a single large genus,

conserves. The young shoots of many species are also edible. The family is named after the Greek myth of the affair between the mortal Krokos (or Crocus) and the nymph Smilax, whose punishment was to be turned into the prickly vine Smilax aspera.[48]

Flowers of Lilium candidum
Lilium candidum

Liliaceae

The lily family, Liliaceae, are the largest Liliales family, with 15 genera and about 700 species, though much reduced from earlier circumscriptions, in four subfamilies. Of these genera,

Tulipa and Lilium, but also Fritillaria. Many are also important ornamentals, such as Calochortus, Cardiocrinum, Clintonia, Erythronium and Tricyrtis. The name is derived from the Latin word for lily, lilium, which in turn is derived from the Greek leirion, a white lily.[48][49][40]

Distribution and habitat

Widely distributed but most commonly found in

temperate regions, especially herbaceous taxa in temperate regions of the Northern Hemisphere, and subtropical regions of the Southern hemisphere, including vines.[8] Since many species are cultivated they have been introduced in many regions and consequently worldwide, and a number have subsequently escaped and naturalised.[9]

Uses

Liliales form important sources of food and

veratrine and related compounds from Veratrum (Melanthiaceae) and Zigadenus (Melanthiaceae).[9]
