Explanation: 

Detailed explanation-1: -Pressing: Use a press made with a pair of hardboard or plywood boards cut to the same size as the drying paper. Place some corrugated card on one board, then place two sheets of the blotting paper on top of this. Arrange your plant material on blotting paper retaining the character of the plant.

Detailed explanation-2: -In a herbarium, plants are dried in a forced-air plant drier that approaches temperatures of 100°C. Presses are placed in the drier in such a manner that the hot air can be blown up through the cardboard corrugates to help dry the plants more evenly.

Detailed explanation-3: -To make a herbarium specimen, the plant is collected, and notes are made about it. The plant is then pressed until dry between blotters that absorb moisture and mounted onto a herbarium sheet with a suitable label.

Detailed explanation-4: -Place another piece of newspaper on top of the plant. Make layers. Place the pieces of newspaper with your specimen inside between two pieces of blotting paper, then between two pieces of corrugated cardboard, to allow air to circulate. Place the resulting package in the plant press and gently screw it down.
