Method steps

1. The main collections are of dried, vascular plants, mounted on thick-grade archival paper and placed in species folders within genera, and arranged by plant family within vacuum-sealed metal cabinets. The room temperature is maintained at 20℃ to prevent the deterioration of the plant material by pests and diseases. The general process for this was as follows: 1. Collected plant specimens were dried and pressed in the field by stacking the newspaper folders in a plant press. 2. At the laboratory the specimens were examined, sorted, re-arranged in their folders and the field notes checked. They were restacked in the presses and subjected to proper drying. 3. Sufficiently dried specimens were decontaminated by deep freezing for a week to kill all stages of insects with which they may be infested. 4. Mounting and identification was done; identifications were confirmed or made using a variety of literature sources (scientific papers, books, online resources).
