Seeds collected: 1993-2000
This is a list of all species collected by the seed-collectors during the years 1993-2000. The main purpose is for the collectors to check the recorded details, and add to them or amend them if required.
There is an example entry at the top to explain the fields. The initial letter abbreviation of the genus is commonly used when listing several members of the genus. Don't do this without giving the genus first, or I won't know what genus you mean!
