A botanist by trade has to collect species of plants, herbs and flowers and preserve them. They are meant to be housed in a herbarium, a collection of dried plants and an educational and research institution. This location becomes a reference center for verification of identifications, a documentation facility, and a data storehouse used by experts.
To begin, the plant has to go through pressing. A common plant press can be made from corrugated cardboard, felt or ink blotters, and plywood endboards. According to Loren C. Anderson, Professor of Botany and Curator of the Herbarium at Florida State University, every botanist should carry a field book, in which you record the location, date of collection, habitat and associated plants, plus, flower color, and plant branching pattern and height, in case those features aren’t evident in the pressed sample.
The plant is laid between newspaper and sheets of blotting paper, which in turn are sandwiched between two corrugates. The blotters draw moisture from the plants, and the ripples in the corrugated cardboard allow the moist air to pass from the press, which expedites drying. After it is completely dry, it is mounted on a sheet of herbarium paper, glued, labeled and stored in a cabinet.
