Explanation:
A herbarium is a critical resource for biodiversity, ecological, and evolutionary research studies. It is a primary data source of dried and labeled plant specimens that is arranged to allow for easy retrieval access and archival storage. A herbarium is like a library, but differs in that the information is stored in a biological form––as pressed, dried, and annotated plant specimens (in the case of most vascular plants; lichens, fungi, bryophytes and some vascular plants are preserved slightly differently, although the main points are the same). The Duke Herbarium (DUKE) has acquired its specimens over time primarily through research-directed field collections by Duke faculty, staff, and students, but also by gift and exchange with other herbaria worldwide.
