Loans may be made to recognized herbaria and botanical institutions engaged in taxonomic research.The director of the borrowing institution assumes responsibility for the care and return of specimens. Loans are made for a period of one year, with extensions possible with the permission of the director. Loaned specimens must not be removed from the borrowing institution, and they may not be transferred from one institution to another without written permission and agreement of all parties concerned.
All loaned specimens should be annotated as fully as possible before being returned. Annotations should be typewritten or handwritten legibly on acid-free archival paper with indelible ink (no ballpoint pens or felt marker pens), and should be affixed to the herbarium sheet adjacent to the original label.
microscopy, DNA extraction, or other destructuve analyses may be
receiving permission. Requests should be made
in writing and
include the sampling protocol, a specific list of the specimens in
question, and the goals of the research project. Any specimen that is
destructively sampled should
information on the annotation label.
It is expected that loans of specimens from HPSU will be acknowledged in any resulting publications, reports, or presentations. We also would appreciate receiving a copy of any such publications or reports.
No dried specimens may be brought into the main collection (Rm 421A) until they have been sterilized by freezing. There is a freezer available for use in the anteroom of the Herbarium.
Procedures for Examining Herbarium Specimens
We are extremely grateful for any annotations that are made to the identification or taxonomy of specimens. If you wish to make an annotation, please contact a staff member for instructions and materials for making an archival annotation label.
Requests for Data
Data for many of our specimens are available through the Oregon Flora Project atlas Additional specimens at HPSU will be imaged and databased in 2011 in collaboration with the Consortium of PNW Herbaria and the Oregon Flora Project.
