  The Scientist : Arthur Cronquist   (Site not responding. Last check: 2007-10-14)
Arthur Cronquist, a senior scientist at the New York Botanical Garden who developed an evolutionary classification system for flowering plants that has become a standard in the field, died March 22.
Cronquist died of a heart attack at the Brigham Young University Herbarium in Provo, Utah, while working on a compendium of flora of the intermountain United States.
Cronquist received the Asa Gray Award from the American Society of Plant Taxonomists in 1985 and the Linnean Medal for Botany from the Linnean Society of London in 1986.

Conversely, Cronquist reveals an essentially phenetic approach to systematics on page 2: "taxonomy is a study aimed at producing a system of classification of organisms which best reflects the totality of their similarities and differences".
Cronquist makes a common error in suggesting that "taxa are properly established on the basis of multiple correlations of characters" (page 5; emphasis is mine).
Cronquist correctly rejects the hypothesis of an "Amentiferae" ancestor, in which the unisexual strobili of the Gnetales are homologised with those of hamamelid families with catkins (Wettstein 1907).

 PBIO 250 Lecture Notes -- History -- Spring 1998: Arthur Cronquist
Arthur John Cronquist was a giant of a person, large in size, massive in voice, and overwhelming in personality.
He and Arthur Holmgren, at Utah State University, initiated a study of the Intermountain West in 1959, with Cronquist concentrating on the multi-volumed, illustrated flora of the Pacific Northwest with C. Leo Hitchcock and Marion Ownbey.
Cronquist was unwilling basically to change his system (he made only minor changes in 1988 in a second edition of his book on Evolution and Classification) whereas the others often made frequent changes to reflect new knowledge.

Cronquist was an authority on the family Compositae and authored three textbooks on introductory botany.
Arthur Cronquist was known for his towering physical stature, tall tales, and congeniality as well as for his commanding position as a botanist and educator.

 Cronquist system
The Cronquist system is a scheme for the classification of flowering plants (or angiosperms).
This system was developed by Arthur Cronquist[?] in his texts An Integrated System of Classification of Flowering Plants (1981) and The Evolution and Classification of Flowering Plants (1988).
Cronquist's system places flowering plants into two broad classes, monocots[?] and dicots.

Most of Cronquist's constellations and concepts are undoubtedly wise and have a greater public appeal than those of other classifications, in which the hierarchy is more complicated or the orders and families split into more entities or both.
Cronquist claims that the earliest angiosperms were probably shrubs of riparian habitats and had monosulcate pollen grains and leaves with irregular pinnate-reticulate venation.
The close relation between Nymphaeales and monocotyledons is emphasized, and, although Cronquist does not suggest that the Nymphaeales are direct ancestors to the monocotyledons as a whole, he concludes that the premonocotyledonous dicotyledons probably somewhat resembled the modern Nymphaeales.

 FLORA OF NORTH AMERICA - Volume 1, Chapter 14
Cronquist (1987) and others have discussed some of the problems of applying this concept.
The general system of classification of angiosperms used in the Flora of North America is the "integrated system" of A. Cronquist (1981, slightly modified in 1988).
If my hypothesis of chemical evolution (A. Cronquist 1977b, elaborated in 1988) is correct, the Dilleniidae probably originated about the same time as the Hamamelidae and the Rosidae.

 Systematics of the Apiales
The strongest proponents of this hypothesis are Leon Takhtajan and Arthur Cronquist.
Regarding the Apiales' relationship to other angiosperm groups, some believed that Apiales was closely related to Cornales, but Arthur Cronquist (1988) believed there was a closer relationship between Apiales and Sapindales, based on the presence of similar chemicals in the two orders.
Nevertheless, Cronquist refused to acknowledge the inclusion of Pittosporaceae in Apiales, stating that Pittosporaceae originated from lower rosids, while Apiales was more advanced.

 Botanical Taxonomic Schemes
These are the systems of Arthur Cronquist, RMT Dahlgren, and the Angiosperm Phylogeny Group (APG).
However Cronquist places it in the Cistaceae, Violales, adjacent to the family Violaceae (Viola odorata, Viola tricolor) - which allows us to reflect upon some fascinating concordances with these latter two remedies, helping us to appreciate the scope of action of this relatively small (657 rubric) remedy.
Although the Dahlgren and Cronquist schemes classify these remedies in those same respective families, they do not relate these two families closely to one another; and hence fail to bring these two remedies of very similar properties together for comparison.

This second edition of the Manual was completely revised by Cronquist, the taxa rearranged according to his phylogenetic system, and the nomenclature updated.
This edition reflects an effort to incorporate into a single comprehensive account the results of modern taxonomic research on the flora of the area covered, with due regard to all past accounts, all in the light of Cronquist's critical evaluation.
The aim is to make it possible for the user to correctly identify a plant using only a hand lens or occasionally a dissecting microscope.

The families are arranged in the traditional Englerian sequence except that the monocots follow the dicots and are arranged according to Cronquist's The Evolution and Classification of Flowering Plants, 1968.
One is tempted to fantasize conversations between the two authors as they argued over which type of key was best and which could write the better one, the outcome being that they both decided to try their luck and let the reader decide.
The differing philosophies of the authors are expressed in that the synoptical phylogenetic key is written by Cronquist and the illustrated artificial key is written by Hitchcock.

 Book Summary : An Integrated System of Classification of Flowering Plants by Arthur Cronquist   (Site not responding. Last check: 2007-10-14)
Customer Book Summary: This book is a classic and should be part of the reading list in an advanced and intermediate systematics and plant taxonomy class.
Lets not forget the many descriptions of the families and the systematic discrepancies that the author said need to be carefully studied.
It is easy to think that in todays phylogenetics classification Cronquist's contribution would not fit, but that is not the case with this book in which morphological, anatomical, palynological, biogeographical and paleobotanical data offer a unique picture of each taxonomic group, regardless of todays results by means of other techniques.
