Collection Numberingheadline bar Example of unambiguous numbering system If you already have an unambiguous numbering system for your collections, we encourage you to continue with that. In our system, we include the initials of the collector, a four digit number to indicate the year collected, a three digit sequential number assigned to the population collected, and a three digit sequential number assigned to the specimen sampled within that population. Thus, if John A. Doe collects a voucher of Fraxinus from his tenth collection for 2008, the collection number for the third tree from that population would be coded as JAD/2008/010/003. The year (2008) is followed by the collection site (010) which is followed by the tree that was sampled (003). **JAD / 2008 / 010 / 003****JAD**
