摘要：Current systems for storing reference collections of 'seeds' (and. similarly-sized
organisms such as molluscs) include the following, which we may term the 'Hillman' system,
the 'Institute of Archaeology' system, the 'metal case' system, and the 'paper envelope1
system:
The first of these, the 'Hillman' system, was used to build up the 'seed' reference
collections in the Botany Department of University College, Cardiff and the British School
in Ankara, Turkey. It consists of two ranks of glass tubes held at their bases in narrow
wooden racks. The small racks are easy to handle and make the stored material easily
visible. The disadvantages, however, are that all the racks had to be made specially for
the purpose and were therefore expensive. They can only store a small number of species
(maximum 20) at one time and, if dropped, all embedded tubes may separate from their rack.
