Шаблон:Short description Шаблон:Use dmy dates Шаблон:Automatic taxobox Amaryllidoideae (Amaryllidaceae s.s., amaryllids) is a subfamily of monocot flowering plants in the family Amaryllidaceae, order Asparagales. The most recent APG classification, APG III, 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.

The Amaryllidoideae are herbaceous, perennial flowering plants, usually with bulbs (some are rhizomatous). Their fleshy leaves are arranged in two vertical columns, and their flowers are large.Шаблон:Sfn Most of them are bulbous geophytes and many have a long history of cultivation as ornamental plants. They are distinguished from the other two Amaryllidaceae subfamilies (Agapanthoideae and Allioideae) by their unique alkaloidal chemistry, inferior ovary, and hollow style.Шаблон:Sfn

History

Pre-Darwinian

The name Amaryllis had been applied to a number of plants over the course of history. When Linnaeus formerly described the type genus Amaryllis, from which the family derives its name, in his Species Plantarum in 1753,Шаблон:Sfn there were nine species with this name. He placed Amaryllis in a grouping he referred to as Hexandria monogynia (i.e. six stamens and one pistil)Шаблон:Sfn containing 51 genera in allШаблон:Sfn in his sexual classification scheme.

These genera have been treated as either liliaceous or amaryllidaceaeous (see Taxonomy of Liliaceae) over time.Шаблон:Sfn In 1763 Michel Adanson placed them in 'Liliaceae'Шаблон:Sfn In 1789 Antoine Laurent de Jussieu placed Amaryllis and related genera within a division of Monocotyledons, using a modified form of Linnaeus' sexual classification but with the respective topography of stamens to carpels rather than just their numbers.Шаблон:Sfn

The family Amaryllidaceae was named in 1805, by Jean Henri Jaume Saint-Hilaire.Шаблон:Sfn In 1810 Brown proposed that a subgroup of Liliaceae be distinguished on the basis of the position of the ovaries (inferior) and be referred to as AmaryllideaeШаблон:Sfn and in 1813 de Candolle described Liliacées Juss. and Amaryllidées Brown as two quite separate families.Шаблон:Sfn Samuel Frederick Gray's A natural arrangement of British plants (1821).Шаблон:Sfn grouped together a number of families having in common six equal stamens, a single style and a perianth that was simple and petaloid, within which he separated families by the characteristics of their fruit and seed, such as Amaryllideae, Liliaceae, Asphodeleae and Asparageae.Шаблон:Sfn

John Lindley, in his An Introduction to the Natural System of Botany (1830)Шаблон:Sfn divided the "Monocotyledonous Plants" Шаблон:Sfn into two tribes. He then further divided the Petaloidea (petaloid monocots), into 32 orders, including the Amaryllideae.Шаблон:Sfn He defined the latter as "Hexapetaloideous bulbous hexandrous monocotyledons, with an inferior ovarium, a 6-parted perianthium with equitant sepals, and flat spongy seeds" and included Amaryllis, Phycella, Nerine, Vallota, and Calostemma.

By 1846 Lindley had greatly expanded and refined the treatment of the monocots.Шаблон:Sfn He placed the Liliaceae within the Liliales, but saw it as a paraphyletic ("catch-all") family, being all Liliales not included in the other orders, hoping that the future would reveal some characteristic that would group them better. This kept the Liliaceae.Шаблон:Sfn separate from the Amaryllidaceae,Шаблон:Sfn which was divided into four tribes (with 68 genera), yet both his Amaryllidaceae and Liliaceae contained many genera that would eventually segregate to each other's contemporary orders (Liliales and Asparagales respectively). The Liliaceae would be reduced to a small 'core' represented by the tribe Tulipeae, while large groups such as Scilleae and Asparagae would become part of Asparagales either as part of the Amaryllidaceae or as separate families. Of the four tribes of the Amaryllidaceae, the Amaryllideae and Narcisseae would remain as core amaryllids while the Agaveae would be part of Asparagaceae but the Alstroemeriae would become a family within the Liliales.

Since then seven of Linnaeus' genera have consistently been placed in a common taxonomic unit of amaryllids, based on the inferior position of the ovaries (whether this be as an order, suborder, family, subfamily, tribe or section).Шаблон:Sfn Thus much of what we now consider Amaryllidoideae remained in Liliaceae because the ovary was superior, till 1926 when John Hutchinson transferred them to Amaryllidaceae.Шаблон:Sfn

The number of known genera within these families continued to grow, and by the time of the Bentham and Hooker classification (1883) the Amaryllidaceae (Amaryllideae) were divided into four tribes, of which only one (Amarylleae) still represents the grouping now reflected in Amarylloideae.Шаблон:Sfn

In the post-Darwinian era the amaryllids were mainly treated as part of a very large family Liliaceae, although the early twentieth century saw increasing doubts about the inclusion of many of its components, particularly the alliaceous (i.e. Allioideae) elements. Hutchinson also suggested that the elements now included in Amaryllidoideae's parent family (Amaryllidaceae) could all be placed in one family, although only Cronquist placed all the elements into a very large Liliaceae.

Angiosperm Phylogeny Group

The introduction of molecular methods in the 1990s confirmed the affinity of three major taxa corresponding to Alliaceae, Agapanthaceae and Amaryllidaceae.Шаблон:Sfn In 2009 the Angiosperm Phylogeny Group (APG) decided to amalgamate the three families, which together form a monophyletic group, into a single family, at first called Alliaceae and then Amaryllidaceae.Шаблон:Sfn The three families then became reduced to subfamilies, so that the historical Amaryllidaceae became subfamily Amaryllidoideae. To distinguish this new broader family from the older narrower family it has become customary to refer to Amaryllidaceae sensu APG, or as used by APG, Amaryllidaceae s.l.. as opposed to Amaryllidaceae s.s..Шаблон:SfnШаблон:Sfn

The relationships between the subfamilies within the Amaryllidaceae and the place of Amaryllidoideae is shown in the Cladogram.

Subdivision

Complete resolution of infrafamilial (suprageneric) relationships within subfamily Amaryllidoideae (Amaryllidaceae s.s.) has proven difficult.Шаблон:Sfn Early studies lacked sufficient resolution for further elucidation of this group.Шаблон:Sfn Historically a wide variety of infrafamilial classification systems have been proposed for the Amaryllidaceae s.s.. In the latter twentieth century there were at least six schemes, including Hutchinson (1926),Шаблон:Sfn Traub (1963),Шаблон:Sfn Dahlgren (1985),Шаблон:Sfn Müller-Doblies and Müller-Doblies (1996),Шаблон:Sfn Hickey and King (1997)Шаблон:Sfn and Meerow and Snijman (1998).Шаблон:Sfn Hutchinson was an early proponent of the larger Amaryllidaceae, transferring taxa from Liliaceae and had three tribes, Agapantheae, Allieae and Gilliesieae. Traub (who provides a brief history of the family) largely followed Hutchinson, but with four subfamilies (Allioideae, Hemerocalloideae, Ixiolirioideae and Amaryllidoideae), the Amaryllidoideae he then divided further into two "infrafamilies", Amarylloidinae and Pancratioidinae, an arrangement with 23 tribes in total. In Dahlgren's system, a "splitter" who favoured larger numbers of smaller families, he adopted a narrower circumscription than Traub, using only the latter's Amaryllidoideae which he treated as nine tribes. Müller-Doblies described ten tribes (and 19 subtribes). Hickey and King described ten tribes by which the family were divided, such as the Zephyrantheae.Шаблон:Sfn Meerow and Snijder considered thirteen tribes, one (Amaryllideae) with two subtribes (For a comparison of these schemes see Meerow et al. 1999, Table I).Шаблон:Sfn

Thus Traub's Amaryllidoideae, which most later authors treated as Amaryllidaceae s.s., became the basis for Amaryllidoideae sensu APGIII. Of the other three subfamilies in Traub's system, Allioideae represents Amaryllidaceae subfamily Allioideae sensu APGIII. Hemerocalloideae was a small subfamily with a single tribe, Hemerocalleae consisting of two genera, Hemerocallis and Leucocrinum. Subsequent research has shown these to be very different taxa, Hemerocallis being placed in the family Xanthorrhoeaceae, while Leucocrinum belongs in Asparagaceae, both part of Asparagales. Finally Ixiolirioideae was another very small subfamily, with two tribes, Gageeae and Ixiolirieae. Gageeae consisted of two genera, Gagea and Giraldiella, which was subsequently merged with Gagea (Liliaceae, Liliales), while Ixiolirieae similarly contained only Ixiolirion and Kolpakowskia (merged with Ixiolirion) belongs in Ixioliriaceae (Asparagales). so only two of his subfamilies now belong in Amaryllidaceae s.l..

The further application of molecular phylogenetics produced a complex picture that only partially related to the tribal structure considered up to that date, which had been based on morphology alone.Шаблон:Sfn Rather Amaryllidaceae resolved along biogeographical lines. A predominantly South African clade identified as Amaryllideae was a sister group to the rest of the family. The two other African tribes were Haemantheae and Cyrtantheae, and an Australasian tribe Calostemmateae was also identified, but a large clade could only be described as Eurasian and American, each of which were monophyletic sister clades to each other. The Eurasian clade was poorly resolved with the exception of Lycorideae (Central and East Asian). The American clade was better resolved identifying both Hippeastreae as a tribe (and Zephyranthinae as a subtribe within it). The American clade also included an Andean cladeШаблон:Sfn

Further investigation of the American clade suggested the presence of two groups, the Andean clade and a further "Hippeastroid" clade, in which Griffineae was sister to the rest of the clade (Hippeastreae). Similarly within the Andean clade four subclades were identified, including Eustephieae which appeared as sister to the remaining clade, including Hymenocallideae. Of the remaining taxa, two subclades emerged that did not correspond to existing tribal structure, namely Eucharideae (3 genera) and Stenomesseae (6 genera). Rather the taxa segregated on a morphological criterion, namely leaf shape. Stenomesseae was recognised as polyphyletic with two distinct types based on leaf shape (lorate-leafed and petiolate-leafed), while Eucharideae was petiolate, together with three Stenomesseae genera and a number of species of the type genus Stenomesson. Furthermore, the type species of Stenomesson, Stenomesson flavum is petiolate. The consequent petiolate Eucharideae/Stenomesseae subclade could not be further resolved into distinct monophyletic tribes. Subsequent treatment has been variable. Meerow et al. state here that this subclade should be called Stenomesseae because the type species of Stenomesson was petiolate and thus transferred from the former Stenomesseae into the new petiolate clade. Subsequently, Meerow (2004) treated the Andean clade as having four tribes with Eucharis in Stenomesseae.Шаблон:Sfn

However, since then the term Eucharideae has been used instead. For example, in a paper presented at Monocot IV (2008),Шаблон:Sfn a cladogram published in 2013,Шаблон:Sfn and in 2014 only Eucharideae is mentionedШаблон:Sfn while in 2015 Meerow described new species of Stenomesson and Eucharis as being in Eucharideae.Шаблон:Sfn The combined clade would include Stenomessaea as the reduced Stenomesson (sensu stricto), Rauhia, Phaedranassa, and Eucrosia, together with Eucharideae as Eucharis, Caliphruria, and Urceolina.Шаблон:Sfn

Based on the oldest published name for the remaining lorate Stenomesson species, which is Clinanthus, the lorate subclade was designated tribe Clinantheae, and the remaining species transferred. In this redescription, Clinanthus luteus becomes the type species for tribe Clinantheae which includes Pamianthe, Paramongaia and Pucara. Although subsequent analysis resulted in submerging Pucara into Stenomesson (and hence Stenomesseae), rather than treating it as a separate genus.Шаблон:Sfn

The Eurasian clade was also further resolved (for historical treatment, see Table I Meerow et al. 2006) into four tribes, Pancratieae, Narcisseae, Galantheae and Lycorideae. This positioned Lycorideae as sister to the remaining Mediterranean tribes.Шаблон:Sfn

These relationships are summarised in the following cladogram:

Шаблон:Cladogram

Publication of the third version of the APG classification and acceptance of Amaryllidaceae s.l.Шаблон:Sfn was accompanied by a listing of accepted subfamily and tribal names, since the change in rank from family to subfamily necessitated a revision of other lower ranks, as follows:Шаблон:SfnШаблон:SfnШаблон:SfnШаблон:Sfn

Family: Amaryllidaceae J.St.-Hil., Expos. Fam. Nat. 1: 134. Feb–Apr 1805, nom. cons.

This circumscription differs from the phylogenetic descriptions of Meerow and colleagues in several respects, as described above. Griffineae is recognised as a distinct tribe within the Hippeastroid clade, and Stenomesseae is recognised as polyphyletic with two distinct types based on leaf shape and subsequent creation of Clinanthieae as a separate grouping (see Cladogram), the remainder being submerged into Eucharideae.Шаблон:SfnШаблон:SfnШаблон:SfnШаблон:SfnШаблон:Sfn
