To best establish protocols for specimen movement control, a system of documentation can be set up to monitor and control collections. [citation needed] At the National Museum of Natural History, theft is prevented by maintaining limited access to where collections are stored. In the event of a specimen leaving the site through outgoing loans ...
Plant collecting is the acquisition of plant specimens for the purposes of research, cultivation, or as a hobby. Plant specimens may be kept alive, but are more commonly dried and pressed to preserve the quality of the specimen. Plant collecting is an ancient practice with records of a Chinese botanist collecting roses over 5000 years ago. [1]
(i) Collection or accession occurs when a specimen arrives at the biorepository. Information about the specimen is entered into the laboratory information management system ("LIMS"), which tracks information about all of the specimens in the biorepository. Typical information linked to a specimen would be the specimen's origin and when it ...
For some plants it may prove helpful to allow the fresh specimen to wilt slightly before being arranged for the press. An opportunity to check, rearrange and further lay out the specimen to best reveal the required features of the plant occurs when the damp absorbent sheets are changed during the drying/pressing process.

Specimen storage in the wooden cabinets, showing the traditional vertical filing system for preserved plant sheets. These handcrafted cupboards, characteristic of the older wings, store thousands of mounted specimens in organised compartments. The size of the collection has been a subject of historical interest.
A biological specimen (also called a biospecimen) is a biological laboratory specimen held by a biorepository for research. Such a specimen would be taken by sampling so as to be representative of any other specimen taken from the source of the specimen. When biological specimens are stored, ideally they remain equivalent to freshly-collected ...
As a precaution against insect damage, the pressed plant is frozen or poisoned and the case disinfected. Most herbaria use a standard system of organizing their specimens into herbarium cases. Specimen sheets are stacked in groups by the species to which they belong and placed into a large lightweight folder that is
The box was carried horizontally on a strap so that plant specimens lie flat and lined with moistened cloth. [1] Traditionally, British and American vascula were somewhat flat and valise -like with a single room, while continental examples were more cylindrical and often longer, sometimes with two separate compartments.
