Commelinid Families
In plant taxonomy, commelinids (originally commelinoids) (plural, not capitalised) is a clade of flowering plants within the monocots, distinguished by having cell walls containing ferulic acid. The commelinids are the only clade that the APG IV system has informally named within the monocots. The remaining monocots are a paraphyletic unit. Also known as the commelinid monocots it forms one of three groupings within the monocots, and the final branch; the other two groups are the alismatid monocots and the lilioid monocots. Description Members of the commelinid clade have cell walls containing UV-fluorescent ferulic acid. Taxonomy The commelinids were first recognized as a formal group in 1967 by Armen Takhtajan, who named them the Commelinidae and assigned them to a subclass of Liliopsida (monocots). The name was also used in the 1981 Cronquist system. However, by the release of his 1980 system of classification, Takhtajan had merged this subclass into a larger one, an ...

Dactylis Glomerata
''Dactylis Glomerata'' is the sixth studio album by Swedish doom metal band Candlemass, released in 1998. This was their first album released since their split in 1994. The album was originally destined to be the second release by Candlemass main songwriter Leif Edling's side-project Abstrakt Algebra but, under request from the record label Music for Nations, it was converted in a Candlemass album. There were many musicians involved in the long process of recording, including members of the Abstrakt Algebra's line-up, guitarist Michael Amott of Arch Enemy and Carcass fame and new singer Björn Flodkvist. The music on the album lacks much of the epic doom sound of previous works and embraces a more experimental and progressive approach, with elements of stoner rock and space rock. In 2006, it was reissued by GMR Music as a 2 CD edition. The second disc contains the previously unreleased album ''Abstrakt Algebra II'', from which this album's tracks derived.

Cronquist System
The Cronquist system is a taxonomic classification system of flowering plants. It was developed by Arthur Cronquist in a series of monographs and texts, including ''The Evolution and Classification of Flowering Plants'' (1968; 2nd edition, 1988) and ''An Integrated System of Classification of Flowering Plants'' (1981) (''see'' Bibliography). Cronquist's system places flowering plants into two broad classes, Magnoliopsida ( dicotyledons) and Liliopsida (monocotyledons). Within these classes, related orders are grouped into subclasses. While the scheme was widely used, in either the original form or in adapted versions, many botanists now use the Angiosperm Phylogeny Group classification for the orders and families of flowering plants, first developed in 1998. The system as laid out in Cronquist's ''An Integrated System of Classification of Flowering Plants'' (1981) counts 64 orders and 321 families in class Magnoliopsida and 19 orders and 65 families in class Liliopsida.

Cannales
The Zingiberales are flowering plants forming one of four orders in the commelinids clade of monocots, together with its sister order, Commelinales. The order includes 68 genera and 2,600 species. Zingiberales are a unique though morphologically diverse order that has been widely recognised as such over a long period of time. They are usually large herbaceous plants with rhizomatous root systems and lacking an aerial stem except when flowering. Flowers are usually large and showy, and the stamens are often modified (staminodes) to also form colourful petal-like structures that attract pollinators. Zingiberales contain eight families that are informally considered as two groups, differing in the number of fertile stamens. A " banana group" of four families appeared first and were named on the basis of large banana-like leaves. Later, a more genetically coherent (monophyletic) "ginger group" appeared, consisting of the remaining four families. The order, which has a fossil record ...

Haemodorales
Commelinales is an order of flowering plants. It comprises five families: Commelinaceae, Haemodoraceae, Hanguanaceae, Philydraceae, and Pontederiaceae. All the families combined contain over 885 species in about 70 genera; the majority of species are in the Commelinaceae. Plants in the order share a number of synapomorphies that tie them together, such as a lack of mycorrhizal associations and tapetal raphides. Estimates differ as to when the Commelinales evolved, but most suggest an origin and diversification sometime during the mid- to late Cretaceous. Depending on the methods used, studies suggest a range of origin between 123 and 73 million years, with diversification occurring within the group 110 to 66 million years ago. The order's closest relatives are in the Zingiberales, which includes ginger, bananas, cardamom, and others.Stevens, P. F. (2001 onwards). Angiosperm Phylogeny Website. Version 9, November 2011.

Bromeliales
Bromeliales is an order of flowering plants. Such an order has been recognized by a few systems of plant taxonomy, with a various placement. It appears that it always has had the same circumscription: consisting only of the family Bromeliaceae, the bromeliad or pineapple family. The order is not recognized in the APG II system, of 2003, which places the plants involved in the order Poales. Some examples are: * The Cronquist system of 1981 placed this order in subclass Zingiberidae, of class Liliopsida monocotyledons * The Thorne system (1992) placed the order in superorder Commelinanae in subclass Liliidae monocotyledons * The Dahlgren system placed the order in superorder Bromeliiflorae (also known as Bromelianae) in subclass Liliidae monocotyledonstogether with five other orders. * The Engler system, in its update of 1964, placed the order in class Monocotyledoneae Monocotyledons (), commonly referred to as monocots, (Lilianae ''sensu'' Chase & Reveal) are grass and gra ...
