Flowers of Lillium candidum
Lilium candidum
Madonna lily (Liliaceae)

Coronariae (literally a crown or garland) 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.

Coronariae was first used by John Ray in his Catalogus plantarum circa Cantabrigiam (1660) as one of 21 classes of herbaceous plants. In this grouping he included Armerius and Caryophyllus (i.e. Dianthus, Caryophyllaceae).[1] It was next used by Linnaeus in his Philosophia Botanica (1751) to refer to a very different group of plants. Linnaeus followed Ray in describing Coronariae as "a beautiful [flower] which is inserted in crowns or garlands".[2] His Coronariae was the ninth of his 69 ordines naturales (i.e. families), consisting of five genera, followed by Liliaceae and Muricatae. These three orders consisted of the following genera:[3]

9. Coronariae
10. Liliaceae
11. Muricatae

In a later posthumous publication, Praelectiones in ordines naturales plantarum (1792),[4] Coronariae appear as Ordo X with 28 genera, Linnaeus having merged his previous Liliaceae into Coronariae together with his eleventh order, Muricatae.[2][5] In developing an ordered system of taxonomic ranks, Agardh (1825)[6] followed Linnaeus but placed his Coronariae within the higher rank (order) of Liliiflorae and confined it to the original Liliaceae:

At about the same time, Perleb (1826) followed a similar scheme with eleven families grouped into an order he called Liliaceae:[7]

Endlicher (1836) used Coronariae as a class with eight subordinate orders, restoring Liliaceae as the family name:[8]

Subsequent authors, such as Lindley (1853), preferred the term Liliales for a higher order (which Lindley called Alliances), including four families including Liliaceae. Lindley lists Coronariae as a synonym of Liliaceae:[9]

However Bentham (1877) restored the term as one of four alliances making up the monocotyledons, with 8 families:[10]

He developed this further in his Genera plantarum (1883), this time dividing the monocotyledons into seven groups, called Series, of which in Coronariae he added Mayaceae and Rapateaceae, renamed Commelynaceae as Commelinaceae and omitted Junceae and Palmae.[11]

Later alternative nomenclature

Subsequent authors, now adopting a phylogenetic (phyletic) or evolutionary approach over the natural method,[12] did not adopt Bentham's nomenclature. Eichler (1886) used Liliiflorae for the higher order including Liliaceae,[13] as did Engler (1903)[14] and Lotsy (1911).[15]

Hutchinson (1973)[16] restored Liliales for the higher rank, an approach that has been adopted by most major classification systems onwards, reserving Liliiflorae for higher ranks. these include Cronquist (1981),[17] Takhtajan (1997),[18] Thorne and Reveal (2007).[19] This is also the nomenclature of the molecular phylogenetic based modern system of the Angiosperm Phylogeny Group (APG, 1998–2016).[20]

In post-Linnaean usage, Coronariae corresponds to the modern order Liliales (Lilies and allied taxa), the largest grouping of families within the monocot grade Lilioid monocots. The number of families remains about the same as Perleb's original construction. However, the circumscription of the order Liliales (and its nominative family Liliaceae) have undergone major changes over the years, particularly with the advent of molecular phylogenetics. As a consequence, Liliales is greatly reduced, although still a relatively large monocot order. At one stage the Lilaceae, sensu Lindley, which he called lilyworts in the vernacular, consisted of 133 genera and 1200 species.[21] In this work he unhappily acknowledged the confusing array of different approaches to the classification of the Liliaceae, the lack of a clear definition, and the great diversity in the circumscription of the order, which had expanded vastly, with many subdivisions. As he saw it, the Liliaceae had already become a catch-all grouping,[22] being "everything that does not belong to the other parts of the Lilial Alliance", but expressed hope that the future would reveal some characteristic that would group them better. In other words, he foresaw that Liliaceae would come to be regarded as paraphyletic.[23]

Many of the families once considered to be part of this grouping are now considered to be in Asparagales, with the remainder in commelinids and Dioscoreales.[20][24]

Liliales, sensu APG, consists of ten families:[20]

As such, it consists of about 67 genera and about 1,558 species.[25][26] 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. Many of these families are very small or monotypic.[27][28]
