Mounting the Specimen. For over four hundred years people have preserved plants for study by pressing and drying them. A collection of such dried specimens is called an herbarium. Plants that have been thoroughly dried and well mounted, and are protected from moisture and insects, will remain intact essentially forever.Arrange the Specimen Arrange the plant and label on the correct size of the mounting paper before gluing anything down! Labels are placed in the bottom right corner, unless unfeasible due to the shape of the specimen. Annotation slips with name changes go above or to the left of the label.

The mounting board, label paper, capsules, tape and PVA adhesive are all archival quality. White polyester thread is used for stitching. For further information on archival materials see section 2 of RBGE Collections Care: Preparation and Care of Herbarium Specimens (link in the sidebar).

A specimen should ideally be 2540 cm long and up to 26 cm wide, allowing it to fit on a standard herbarium mounting sheet which measures 42 x 27 cm. This is also the approximate size of tabloid newspapers. Plant parts that are too large for a single sheet may be cut into sections pressed on a series of sheets, for example a palm or cycad frond.

The original mounting sheet was dried and flattened in the same manner as the plant, and subsequently saved to serve as a reference for positioning the specimen on the new sheet. The plant specimen and documents were laid out on a new mounting sheet of 100, allnew cotton fiber with a neutral pH of and buffered to resist external acid mounting plant specimens To avoid breaking of any of the plant parts, you will want to mount your dried plant to paper. A heavier paper similar to construction paper works best. Gently put a little glue on the backside of the plant and then paste it to the paper (detailed instructions below). Be Mounting specimens. Herbarium specimens are frequently loaned out to other specialist institutes, so the plants must be securely glued to herbarium sheets. Our current specimens are mounted using museum standards, but as we have very old specimens, we often need to restore them using our modern methods. Purpose. The purpose of mounting dried plant specimens onto herbarium sheets is to preserve the specimens by minimizing damage by handling. Mounted specimens are more safely handled and stored because brittle and fragile parts are supported, and all parts are secured against loss. A mounted collection provides a sound display Mounting specimens. At Royal Botanic Gardens Victoria, flowering plants, macroalgae, gymnosperms (conifers and allies) and pteridophytes (ferns and allies) are secured to Half Demy sized archival card (approximately A3 size). Fungi, lichens, microalgae and bryophytes (mosses, liverworts and hornworts) are placed in packets.
