Final answer:
The statement that an annotation label on a herbarium sheet is permanently glued is not true. Annotation labels are updateable and contain important taxonomic and research information, including the determination date and source.
Step-by-step explanation:
The statement 'It is permanently glued to the herbarium sheet.' is not true about an annotation label on a herbarium specimen. Annotation labels are usually attached in a way that they can be removed or altered as taxonomic changes are made, such as the reclassification of a specimen. Therefore, while they are part of the herbarium sheet, they are not permanently glued since they need to be updateable.
Herbarium annotation labels are essential for maintaining the accuracy of botanical records. They often include details such as the current accepted name of the plant, the determiner's name, the date of determination, and the source of determination. These labels are typically used to convey changes in taxonomy, the results of recent research, or corrections to past identifications. Annotation labels are important tools for researchers, often part of larger research projects that track changes in plant taxonomy or provide new insights into plant diversity. The inclusion of the date of determination and the determination source are crucial for tracking the history and reliability of the specimen identification.
