    1,000 Broadleaf Weeds of North America, an Interactive Guide to Identification.

    The must-have plant identification app for gardeners, landscapers, farmers, Noxious weed control personnel, botanists, horticulturists, nature-lovers, wildflower enthusiasts, hikers, ranchers, homeowners – for anyone who has ever wondered, “what is that weed?” The app is as useful to the amateur enthusiast as it is for professionals in the field of weed science.

    The app allows you to identify plants by specifying characteristics from a variety of categories (e.g. flowers, leaves, stem) and sub-categories (e.g. flower color, leaf shape, stem cross-section). You simply examine your plant and make choices based on its traits. You can choose to focus on very sophisticated characteristics like ovary position, or you can choose to focus on more obvious characteristics such as flower color, plant height, or leaf shape. All characteristics are displayed via detailed scientific illustrations in the interactive botanical glossary, which is as useful to novices as it is to professionals. With each choice you make, the list of possible plants shrinks.

    For example, to identify dandelion:

    Flower color > yellow: reduces the remaining species from 1,000 to 385
    Milky juice > yes: reduces the remaining species from 385 to 44
    Plant height > 2 - 4 inches: reduces the remaining species from 44 to 8

    Now compare

    Highly interactive, the app can even provide suggested characteristics based on ease of use, effectiveness, and the remaining species.

    It is easy to confirm your identification by comparing your specimen to the many colored photos or be directed to the specific page number in your favorite weed reference book.


    Multiple color images of each species (over 4,000 images)

    County/Province-level distribution maps for each species

    Page number references for each species in over 50 of the most commonly used weed identification books

    An interactive glossary of botanical terminology, with beautiful scientific illustrations

    Access to the full data for each species

    Alphabetize the species list by either common or scientific name or search by text string

    In printed form, the information in the database would be over 4,000 pages!

    All images and data can be cached to your Android device, allowing the app to be used in the field where phone and internet access may not be available

    Full in-application documentation is available by pressing Menu > Help and can be printed from

    This app is based on the 1,200 Weeds of the 48 States and Adjacent Canada DVD (see ) created by Dr. Richard Old. The interactive DVD is the most comprehensive weed identification reference ever created for North America.

    Dr. Old is a renowned national and international speaker on the subject of weed identification and newly invasive weed species. He also chaired the session on Interactive Identification Systems at the XVI International Botanical Congress. An expert in forensic botany, he has worked with many law enforcement agencies to solve crimes where plant evidence was involved (see the Forensic Files episode "The Smiley Face Killer" on Discovery Channel). Dr. Old has been the weed identification specialist for Washington State University since 1976 and has also performed the weed identifications for the University of Idaho for many years. He received the Idaho Weed Worker Hall of Fame award in 1990 and was presented the highest award of the Washington State Weed Association in 2005. has used the XID Identification System to produce PC based databases similar to this one for ALL plants, native and naturalized, in 18 western states and 4 Canadian provinces.
