Vascular plant specimens follow the standard format, in that pressed plants of a given individual (whole or in part) are taped or glued to an herbarium sheet of 16.6 x 11.5 inches. Specimen labels on acid-free, 100% cotton bond paper, are attached to the lower right corner of the herbarium sheet. Loose parts or fragments of plant organs are included in envelopes attached to the herbarium sheet.

Bryophytes and lichens are placed in standard bryophyte envelopes, which are then attached to the herbarium sheet. Several specimens of a given taxon may be mounted on the same sheet. If the specimens are very large, they will be stored in appropriately sized boxes. The boxes will be labeled and stored in a separate place in the herbarium.

Algae and some fungi will be stored in 60% ethanol with a small amount of glycerin added to prevent loss of gross morphology as a result of drying.
