Asterales: Facts and details from Encyclopedia Topic(Site not responding. Last check: 2007-10-21)
The Asterales are an order[For more, click on this link] of dicotyledon[For more info, click on this link]ous flowering plant[For more info, click on this link]s which include the composite family Asteraceae[For more facts and a topic of this subject, click this link] (sunflowersunflower quick summary:
An oligosaccharide is a saccharide polymer containing a small number (typically three to six) of component sugars, also known as simple sugars....
Fossil evidence of the Asterales is rare and belongs to rather recent epoques, EHandler: no quick summary.
Asterales contain ca 13.6% eudicot diversity (Magalló et al.
Asterales are basically Takhtajan's (1997) Asteridae, with the addition of sundry Hydrangeales.
On the other hand, there are suggestions that Rousseaceae, Pentaphragmataceae and Campanulaceae are together sister to the other Asterales (Lundberg and Bremer 2003), although the support for this is not very strong.
While the near association of the Menyanthaceae is somewhat supported by the rbcL data, I am not inclined to muddy the water with the addition of a family that otherwise clearly fits in the Campanulanae.
Comp.: 141-248.], 1977 [actually 1978]." One notion is that the origin of the Calycerales is to be sought in the Campanulanae, specifically somewhere near the Goodeniales (Lammers, Ann.
A potential problem with using the Calycerales as a near relative to the Asterales is that the latter are probably primitively woody with opposite leaves whereas the Calycerales are herbs with alternate leaves.
The present study is concerned with the evolutionary relationships among the Euasterids II, a group of angiosperms that includes the orders Apiales, Aquifoliales, Asterales, and Dipsacales together with several small, poorly known families yet unplaced as to order.
Parsimony analysis of nucleotide sequence data from the chloroplast genes atpB, ndhF and rbcL together with morphological data are used to construct a phylogeny of the orderAsterals, which in the present sense includes 11 families and more than 26 000 species.
Using the recently developed Bayesian approach to phylogenetic reconstruction, in combination with a dataset consisting of the atpB, ndhF and rbcL nucleotide sequences, a resolved and fairly well supported phylogeny of the Euasterids II could be reconstructed.

Among the euasterids II outside Asterales, I have been able to support earlier suggestions that Columelliaceae should be included in the order Dipsacales (#11), and I have also given some evidence that Bruniaceae might best be treated as a member of Asterales.
This hypothesis might be tested using a larger data set of distributions and phylogenies of plants, terrestrial animals and shallow water animals showing a circum-Indian Ocean distribution and it also needs to be correlated with geological data.
A reliable biogeographic hypothesis of the orderAsterales also needs to be constructed, which includes a better understanding of the biogeography of the sister group to Rousseaceae, the cosmopolitian familyCampanulaceae.
The genera of Icacinaceae in the traditional sense not placed in any of the above families (all euasterids II) are members of early diverging lineages of the euasterids I and possibly included in the order Garryales.
Order Araliales [closely related to some sympetalous families, especially Solanales, Asterales]
Developmentally sympetalous; a corolla ring develops early in development, then petal primordia form as lobes on the corolla ring -- thus represents an example of "early sympetalae" as seen in Solanales, Asterales.
Separate petals likely a reversal from sympetalous condition.
Forest Plants of the Southeast and Their Wildlife Uses by J.H. Miller and K.V. Miller, published by The University of Georgia Press in cooperation with the Southern Weed Science Society.
Nearly 200 species in 46 genera are treated in this study.
Published posthumously, this volume reflects renowned botanist Arthur Cronquist's long-time interest in the Asterales and completes the work on the Asteridae begun in Volume Four.

The globe-shaped rosette may become 2 ft (0.6 m) or more in diameter with individual leaves up to 1 ft (0.3 m) long and usually less than 1/2 in (1.3 cm) wide.
