Visitors to this expansive website would be wise to check out the "About Us" section to learn the complete definition of what herbaria briefly: "collections of preserved plant and fungal specimens and their associated data...concerned primarily with scientific research and documenting the vast diversity of plant and fungal life." The "About Us" section also explains how specimens are used and stored and it is a nice prelude to the rest of the site. Visitors will learn that a properly stored plant specimen can last centuries, such as the specimens collected by Joseph Banks on Captain Cook's 1770 voyage to Australia that the Herbarium holds. Since the Herbarium is not open to the public, the digitization of the Herbarium collections is important, particularly for botanists. Those persons interested in "Photographs of Plants" will find them under the "Botanical Information" category. There, visitors can search for plants by "genus", "species" or "family". It is noted how much of the digitization of each collection is complete. Visitors unfamiliar with botanical names of plants can find photographs using a "common name" database.
