The order of links:

The University of Texas Plant Herbarium: Plant Resources Center provides an extensive collection of plant illustrations and scientific data. Color photos. Includes the Gideon Lincecum Virtual Herbarium of medicinal plants in Texas. The Gideon Lincecum is a subset of the site and is fabulous on identification and application of plant attributes for medicine.
