The Weedalogue



A Catalogue of the "Wild" Plants of Philadelphia

The Weedalogue is a project to identify the weeds known in Philadelphia Pennsylvania. For more information on the project, see the "intro" page. All of the photographs included on this site were taken with a digital camera by Gendler in Philadelphia. All scanned plants were collected in Philadelphia as well. There is also now an irregularly updated "updates" page. In addition to the index on the left of this page, there are two indices of botanical names with identifying pictures. (These are large, graphic-heavy pages)

The first species index is the Taxonomic Index which is arranged alphabetically by family and genera.

The second species index is arranged alphabetically by scientific name.

There is also now a text-only species index also arranged alphabetically by scientific name.
