We are pleased to announce the opening of a new web site: CATALOGUE OF
NEW WORLD GRASSES (Poaceae) (CNWG). This is a dynamic website in which
all changes made in the underlying production database are immediately
reflected in the web pages.
<P>The data are recorded in TROPICOS (Missouri Botanical Garden's taxonomic
database, developed by Bob Magill, who also constructed the CNWG web pages).
The data is also partly available in the TROPICOS format through
<P>We estimate that of the ca. 75,000 grass names recorded in TROPICOS,
25,000 names apply to grasses of the New World, and these in turn apply
to roughly 4,000 species. The CNWG is an on-going project to database the
taxonomy, nomenclature, types, synonymy, and distribution for all grasses
occurring from Alaska and Greenland to Tierra del Fuego. It is led by the
six editors listed on the bottom of this message, assisted by many contributing
<P>Completed treatments are available for all species of the subfamilies
Anomochlooideae, Bambusoideae, Ehrhartoideae, and Pharoideae (also printed
in hard copy [due in Feb. of this year], Contr. U.S. Natl. Herb. vol. 39:
1-128). Treatments for other subfamilies are incomplete but are actively
being worked on. The CNWG data can be browsed by means of three indices
(Accepted taxa, All treated taxa, Suprageneric, Generic & Subgeneric
taxa) or searched by entering a scientific name in a search box.
<P>Some features of CNWG web site are the following:
<P>1. Data for ca. 75,000 infrafamilial to infraspecific names
<BR>2. Standardized authority and publication citations for
<BR>3. Cross links to homotypic and heterotypic names.
<BR>4. Type protologue and type specimen data, including subsequent
<BR> and neotypifications.
<BR>5. Accepted CNWG suprageneric and generic classification.
<BR>6. Accepted CNWG taxonomy and synonymy for all taxa so
<BR> by the project.
<BR>7. Alternative taxonomic treatments based on published
<BR>8. Geographical distribution in three formats:
<BR> 1) as recorded by CNWG (mainly
to country level),
<BR> 2) voucher specimen data (incomplete),
<BR> 3) maps (limited at this point
to specimens with recorded
<BR>9. Images (mostly line drawings, field photographs, or
<BR> images, but potentially any kind of
image -- still very incomplete).
<BR>10. Links to W3 TROPICOS and other database projects.
