Detailed explanation-1: -A herbarium is a collection of preserved plant specimens. These specimens may be whole plants or plant parts. These are usually in a dried form mounted on a sheet, but depending upon the material, they may also be kept in alcohol or other preservatives.
Detailed explanation-2: -Herbarium is a collection of plant specimens that are dried, pressed, labelled and preserved on sheets. These sheets are stored and systematically arranged for further scientific study.
Detailed explanation-3: -Herbaria document the world’s flora and provide a constant and permanent record of botanical diversity. This role is increasingly important as the rate of habitat destruction increases and climate change precipitates rapid changes in species’ ranges and all aspects of their ecology.
Detailed explanation-4: -Specimen samples are pressed in a plant press and dried on a plant dryer. Each specimen sample should consist of a stem with attached leaves and, if at all possible, flowers and/or fruits. The roots of herbaceous plants should also be included.
Detailed explanation-5: -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.
