• Collection Organization
• Families: Circumscription
• Modern (Angiosperm Phylogeny Group, APGIII), Engler and Prantl, Bentham and Hooker, Cronquist.
• Families: Arrangement
• Phylogenetic: common systems: Engler and Prantl, Bentham and Hooker, Cronquist, modern based on APGIII or in clades.
  Pros: May be of help to plant identification.
• Alphabetical by Family: You still must choose a system for circumscription of families.
  Pros: Generally easier for inexperienced users.
• Genera: alphabetical or phylogenetic.
• Species:
• Split genus geographically and file species in geographic regions. The folders are typically color-coded.
• Alphabetical and geographic at the species level (may be color-coded). This may require more folders and take more space.
• Many alternative schemes such as the FLAS “Florida” system.
  Arrangement guide for the University of Florida Herbarium Vascular Plant Collection.
• Issues:
• Adding new families, especially new ones that don’t “fit” the system.
• Adding new genera.
• Where to file cultivated plants? Under the original place of collection, if it is known? Completely separate from the collection?
• Special collections: types, historic sets.
• Folders and Other Collection Storage Materials
  These materials must all be of archival quality and have a significant cost.
• “genus” folders – > $0.50 each
• “species” covers – ca. $0.25 each
• custom made white, paper covers – ca. 0.13 each
• Specimen Repair (see brief explaination in the FLAS mounting guide)
• Specimen Nomenclature Updates
• Pest Control and Fumigation
