Classification Tables for 28 taxonomic treatments of Triticum
and Aegilops are now posted on the GrainTax web site (http://wheat.pw.usda.gov/ggpages/GrainTax/).
All of these classifications were produced during the 20th century,
and, as a whole, they present a confusing array of inconsistent
names and competing claims of accurate phylogenetic concepts.
Although the classification tables do not alleviate this problem,
they do offer a reliable reference for treatments that are encountered
in the literature and in communications among members of the wheat
research community. Researchers are encouraged to make use of
them for checking the correct citation of species names and for
verifying the handling of taxa within a particular treatment.
Also available on the GrainTax site are the following supplementary
tables: a Table of Authorities with correct spelling and abbreviations
for the publishing author of valid taxonomic names; a Synonym
Table with a list of the most commonly encountered synonyms; and
a Rejected Name Table with a list of illegitimate, invalid, and
ambiguous names. In the next stage of the project, crossreferencing
links will be built to join names to classifications and to relate
valid names to their synonyms.
The goals of the GrainTax project will best be realized with
the coöperation of the wheat research community (Morrison
and Raupp 1999). The Tables are now easily accessible and, when
followed, ensure consistency in the use of taxonomic names.
To avoid confusion in referencing wheat taxa (e.g., in research
articles or in germ plasm requests), it is advisable to cite the
classification that is being followed and to follow the classification
without changes to the names of taxa, their ranking, and their
