  • For plant identification, collect the whole plant, if possible, including flowers and fruit.

  • Refrigerate any specimens that cannot be shipped immediately.
  • Enclose the completed sample form and place them in a plastic bag to protect them from moisture and soil.
  • To ensure timely delivery, send samples early in the week.
