The Liliales are a diverse order of predominantly perennial erect or twining herbaceous and climbing plants. Climbers, such as the herbaceous Gloriosa (Colchicaceae) and Bomarea (Alstroemeriaceae), are common in the Americas in temperate and tropical zones, while most species of the subtropical and tropical genus Smilax (Smilacaceae) are herbaceous or woody climbers and comprise much of the ...
Common characteristics include large flowers with parts arranged in threes: with six colored or patterned petaloid tepals (undifferentiated petals and sepals) 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 ...
In addition such molecular studies show that share characteristics do not necessarily indicate descent from a common ancestor but rather may arise from adaptive convergence in similar habitats. [54] The fossil record of Liliales is relatively poor, [103] but Liliaceae fossils have been dated to the Paleogene [104] and Cretaceous periods in the ...
The APG II system, of 2003 (unchanged from the APG system, of 1998), recognizes this family and places it in the order Liliales, in the clade monocots. Earlier it was a family of two genera, Heterosmilax and Smilax, but DNA studies have shown that Heterosmilax has arisen from Smilax and the two genera are now merged. This results in Smilax ...
The APG III system, of 2009 (unchanged from the APG systems, of 1998 and 2003), recognizes this family and places it in the order Liliales, in the clade monocots. [1] It is a group of herbaceous perennials with rhizomes or corms.
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).
This placed two orders, Liliales and Orchidales into the subclass Liliidae, and did not contain the Lilianae. [41] By contrast Thorne, who produced his system in 1968, [42] created five superorders amongst the monocotyledons, but called the superorder corresponding to Lilianae, by the older name of Liliiflorae, with only one order, Liliales ...
The APG II system, of 2003 (unchanged from the APG system, of 1998), treats the family in the order Liliales, in the clade monocots.The APG III system, of 2009, merged the obscure family Luzuriagaceae into the Alstroemeriaceae, since the former group included only two genera, was the sister group of the Alstroemeriaceae, and possessed the same distinctive twisted petioles.
