This organization held its recent meeting in Xalapa, Mexico,
immediately after the IOPI one, so delegates could conveniently
attend both.

TDWG was started in 1985 as an international working group to explore
ideas on standardization and collaboration between major plant
taxonomic database projects.  Members include institutions and
individuals responsible for botanical databases.  TDWG is affiliated
with the International Union of Biological Sciences (IUBS) as the
Commission on Plant Taxonomic Databases.  The goal of TDWG is to
establish international collaboration among plant taxonomic database
projects so as to promote wider and more effective dissemination and
exchange of information.

TDWG recognizes that existing taxonomic databases will use different
software, hardware and file structures.  The primary objective of the
organization has been to promote common use and interpretation of
terminology, data fields, dictionaries, and common logical rules and
data relationships.  To further this aim, TDWG forms working
subgroups to develop standards and considers other standards
developed independently by institutions and individuals.  TDWG annual
meetings provide a forum for discussing the form and content of the
proposed standards, for voting on the adoption of standards, and
discussing other aspects of taxonomic databases.  The standards
adopted by TDWG are made available in published form so that those
responsible for taxonomic databases may consider them, both in the
planning of new projects and in the management of existing ones.

The Xalapa meeting adopted the work of Frances Cook (Kew), who has
prepared a set of Economic Use Descriptors.  A TDWG subgroup has been
working to obtain a simple system of wide applicability to categorize
the economic uses of plants.  The new Supplementary volume to
Botanico-Periodicum-Huntianum was also adopted as a standard for use
in the citation of periodicals and their abbreviations.  (BPH had
already been adopted, as has Stafleu & Cowan's monumental Taxonomic
Literature, 2nd ed.)  A proposal by M. Morat on behalf of the
Phytogeography Group to adopt Takhtajan's scheme was carried.  The
meeting also adopted Brummitt & Powell's book Authors of plant names
for author abbreviations, replacing Meikle's Draft Index.
Considerable time was spent in working groups discussing Accessions
data under the able chairmanship of Professor Robert Haynes of
Alabama, who stood in for Dr Jim Beach of Harvard.  Since all
subgroups (and the published standards) all use dictionaries of
terms, it is necessary to check the o

Other groups are covering Descriptors for plants, Habitats, Threats,
Geographic Information Systems, Types and Lectotypification Data,

After IOPI and TDWG delegates, stayed for a symposium with a number
of papers being read, including one on the use of bar-codes by Rusty
