Contributors

Introduction
Botanical specimens can exist in many forms, the most common of which are dried, pressed and mounted on paper or dried and stored in archival packets. Additional preparation types include:
- Alcohol preserved
- Bulk collection
- Cleared and stained (slides)
- Dried tissue (silica or cryo)
- Formalin/FAA preserved
- Live culture
- Lyophilized (freeze-dried)
Botanical specimens should be accompanied by informative labels about the specimen(s) (see Labeling Natural History Collections).
Mounted specimens
The majority of botanical specimens are pressed, dried, and then glued, sewn, or taped to archival paper using archival (acid-free) materials.
