  Commelinales
The Commelinales are an order of monocots, including the spiderwort family, Commelinaceae[?].
In their place, a series of forms formerly classified in the Liliales have been realized to have closer affinities to the Commelinidae, and so are either grouped in the Commelinales or in a separate, possibly paraphyletic, order Philydrales.
This variability in membership makes characterization of the Commelinales, beyond being the Commelinaceae and its close relatives, very difficult.

 Commelinales
COMMELINALES + ZINGIBERALES: Inflorescences with many-flowered cincinnal [rather zig-zag cyme] branches; tapetum invasive or plasmodial.
Stem-group Commelinales are dated to ca 114 mybp, divergence within the group to ca 110 mybp (Janssen and Bremer 2004); the corresponding dates in Wikström et al.
The fruit is a single-seeded berry, and the seed itself is bowl-shaped as it comes to surround the placenta during development.

The position of the family Dasypogonaceae was not fully resolved, but it is clearly isolated from Commelinales, Zingiberales and Poales.
Within the Commelinales, Haemodoraceae and Pontederiaceae were strongly supported as sister taxa, as were Commelinaceae and Hanguanaceae.
We also address the identity of the sister-group of the commelinoids, and discuss various aspects of the molecular evolution of the regions examined.

The majority of the species are terrestrial herbs, although species of the Xyridaceae are commonly found in marshy places, and Mayaca is an aquatic.
The circumscription of the Commelinales has been restricted by all of the recent authors.

group, the Commelinales, shows floral adaptations associated with entomophily (showy flowers with well developed corolla) whereas the more derived orders are mostly anemophilous.
Thus, the trend or phyletic pattern within this group, as envisioned by Cronquist, is toward floral reduction and other adaptive changes linked to the wind-pollinated reproductive 'syndrome'.
Our coverage of this group includes the base (Commelinales), intermediate types of the Juncales, and advanced elements of the large order (more than 80% of the species in the subclass) Cyperales and the very distinctive Typhales.

Flowers occur in compact involucrate capitula that superficially resemble inflorescences found within the Asteraceae, hence the description "Composites of the monocots." The Eriocaulaceae has traditionally been considered a natural group and allied with the Commelinales.
The monophyly of the family has been supported by recent studies utilizing molecular data such as rbcL, although the close relationship to the Commelinales has been discarded and a closer relationship to the Poales proposed.
In contrast to strong familial support, relationships within the family have proven difficult to determine.

 Commelinid Monocots Working Group
A group of professional plant systematists with research interests in the Commelinid Monocots.* The working group was initiated with the "Commelinales Workshop," which took place at the Smithsonian Institution, National Museum of Natural History, 17-18 December 1999.
A monophyletic group of monocotyledonous angiosperms that are united by DNA sequence data as well as the general chemical apomorphy of cell-wall bound, UV-fluorescent ferulates (e.g., ferulic, coumaric, dicoumaric acids).
The Commelinids include the Arecaceae (palm family), Zingiberales (bananas, gingers), Commelinales (defined here as consisting of 4 families), Poales, sensu lato, and an assemblage of other groups of currently uncertain affinities.

A workshop on Commelinales and related groups, such as the Zingiberales, was held in the Department on 17-18 December 1999.
The idea for the workshop arose from informal discussions among Faden, Evans, Simpson and Stevenson at the Monocots II Symposium in Sydney, Australia in September 1998.
The topics presented included molecular phylogenies of different groups, using a variety of genes, morphological character distributions within Commelinales and within the larger commelinid lineage, and the position of the Hanguanaceae, a family that shows relationships with both the Commelinales and Zingiberales.

It is sometimes known as the "Bloodwort family".

The family then includes about a dozen genera, totalling several dozen species, of perennial herbaceous plants.
