Packaging and Delivery of Specimens Careful packaging and quick delivery of the specimens is essential. Carefully shake off dew or excess water and allow to air-dry before packing. Press non-woody plants or leaves on small branches between paper and place between two pieces of stiff cardboard. Place the sample in a padded envelope. Soft, succulent plants that are packed in airtight plastic frequently decay before their arrival.
Place leaves between dry paper towels before packing.
For mailing, use strong containers such as corrugated boxes or mailing tubes that will not crush in transit. Fill empty spaces in mailing cartons with crushed or shredded paper to protect the specimen. Use overnight mail services or mail packages early in the week to avoid weekend layovers at the post office.
