VISITORS BOOK:  Please write your full name, full address, and taxa investigated or purpose for visiting the herbarium in the visitors book.

WORK AREA:  Use only room no. 504 for your study. Remove specimens with cover sheets for your study and return them to their original location.

HANDLING SPECIMENS:  Herbarium specimens should not be bent, folded, or laid face down. Do not transfer specimens to different cover sheets. When misidentified specimens are found, however, please annotate them with the correct name and leave them out. A member of the curatorial staff will refile them.

INSECT PESTS:  To keep the herbarium free from insect pests, please do not bring specimens into the herbarium from outside. Do not bring coats or bags into the herbarium.
Smoking, food and drinks are not allowed in the herbarium, nor while studying or handling specimens.

REMOVAL OF MATERIALS:  Removal of material from herbarium specimens is not allowed without prior approval of the curator of the herbarium. Dissected flower parts should be placed in a packet attached to the herbarium sheet when the dissection is finished.

ANNOTATIONS:  Annotations should be legibly written on annotation labels. Visitors may use our labels, which are available from staff members. Whenever possible, the annotation should include the generic name and specific epithet, authority, annotator's name (not initials only) and institution, and the date in permanent blue-black or black ink, NOT BALL POINT PEN.  We request that TYPE SPECIMENS be indicated by the basionym and place of publication. Annotation labels should be attached so that they do not cover any printing, writing, or material on the sheet.

LOANS:  Loans are made only to recognized herbaria and institutions, not to individuals. Requests for loans should be sent to the curator of the herbarium (TI). Do not separate specimens you wish to borrow nor put them in places different from their original location.
