WEED ID is something that many of us have an interest in and we are weak on resources to do this easily. I will try to collect as many InterNet Sites as I can that has information that would help with plant identification. Please send me a message when you find more sites that can be added to this list.

It always helps to see pictures. Try some of the sites below. It helps to know the scientific and/or common name of the plant you are looking for.

• Reference Handout People often ask, What is the best book I can get to identify plants? This list includes over 100 references that I commonly use. Those marked with a star are most commonly used. Come visit my office to take a look.

• TAMU - Image Gallery has 1000's of plants divided into five groups by the first letter of the Family name including Families A-B, Families C-G, Families H-L, Families M-O and Families P-Z. The indexed image link file string query system only requires that a genus or species name be typed into the search blank and then be submitted.

• Native Plants of South Texas This herbarium focuses on native plants from the northern portion of the South Texas Plains and the southern portion of the Hill Country. Collections were made from the area bounded by San Antonio on the east, Sonora on the west, Cotulla on the south and Junction on the north. Click on any of the categories below to access a list of common and scientific names, or use the color chart to find a flower. It includes Grasses and Grass-like Plants, Forbs, and Trees, Shrubs and Vines

• Digital Library Project University of California, Berkeley - - - This site can access 20,361 images of plants. To look for photos, you can choose scientific or common names alphabetically.

• S. M. Tracy Herbarium Checklist. Lets you check the contents of the Tracy Herbarium and if the plant you are interested in is there you can call to arrange to go see it. 409-845-4328

• USDA - Plants Database This seems slow to me but it does find things that no other site lists in any way. The PLANTS Database is a single source of standardized information about plants. This database focuses on plants of the U.S. and its territories and includes: names, checklists, automated tools, identification information, species abstracts, distributional data, crop information, plant symbols, plant growth data, plant materials information, plant links, references, and other plant information. The database is searchable by common or scientific names.

• Plant listing database tells if a plant is a wetland indicator

• The Virtual Garden allows you to search for many plants in their plant encyclopedia.

Much information is available from various Plant Taxonomy Classes. These classes generally approach plant families systematically. Basic characteristics of families are discussed but finding a species name requires going to a KEY.

A description of each plant family is in the DELTA data base called - The Families of Flowering Plants

Before trying to Key a plant to genus or species you first have to determine the correct family. The Botany Department at Colby College has the World Wide Flowering Plant Family Identification - Checklist. First go to FAMILY ID and there you are given a list of plant characteristics that you can check off. Select the characters that are present in the specimen being identified. Press Submit when ready to determine possible families. Pressing "Back" at the top of the window brings you back to the page keeping your character selections. If you have a good sample and answer the list correctly, you will be given one or more of the most likely plant families after submitting your list. Even if you do not use this checklist to determine the Family, the items on the list help you to look for the characteristics that you need to Key out a plant

You can learn a lot about plant identification by looking through the Class and Lab notes for the various plant taxonomy courses on the WEB.

BOTN 201 - TAMU - Taxonomy of Flowering Plants

• Dr. Hugh Wilson
  
• James Manhart

  BOTN 620 - Field Systematic Botany
  

• James Manhart

These are supplemented by strong WWW systems. These pages, open for full public access, include access to the following:
• lab tutorials
  
• lecture notes
  
• exam tutorials
  
• field trip reviews

  and many other sources of information relating to the specific courses and plant systematics in general.

  Sometimes it is helpful to go back and review plant biology try this:

• General Plant Biology from Ohio State University - Department of Horticulture and Crop Science
  
  

Another area of TAMU-BWG research involves the construction of 'gateway' systems that allow users with varying levels of expertise to access biodiversity information as structured by the taxonomic hierarchy. This work, pursued in collaboration with the - - -
• Biota of North America Program
  is exemplified by the - - -
  
• Flora2k System

  This system provides entry to the - - -
  

• BONAP checklist at the North Carolina Botanical Garden

  via vascular plant Family or vascular plant generic names

• techhical names
  
• common names

The Flowering Plant Gateway allows the user to 'browse' through the higher levels of the Authur Cronquist taxonomic hierarchy to locate information that might be available on the internet for a given family. There are numerous links within each family.
