Individuals wishing to bring in material for comparison should make arrangements for fumigating the material well in advance of the visit. The curatorial staff of the Herbaria will assist visitors with an introduction to the collections. Study carrells and dissecting microscopes are available for short-term use. As indicated, any specimen from which material is removed must be annotated with the appropriate information. Dissections or loose plant fragments should be put into packets attached to the sheets.
Additional packets are available from staff members.
Annotations should be written legibly in permanent black ink on annotation labels. Labels and pens are available from staff members. For type specimens , we ask that the basionym and place of publication be indicated. Annotation labels should be attached so that they do not cover any printing, writing or material on the sheet. When necessary, they may be attached by one end only.
