| Micro-Herbaria | Español - Back to Plant Guides Home |
The Micro-Herbaria are desktop-produced books and now being developed as inexpensive CDs. They are most uesful to botanists and others who are accostomed to comparing pressed and dried specimens. Each book is a compilation of scanned or photocopied herbarium specimens of plants for a specific area. These are reduced and printed to US letter size (8.5 by 11 inch) and bound in stiff plastic or heavy paper covers, or printed to a CD.![]() Until recently, all our micro-herbaria were made using a commercial photocopier with microfine toner (Minolta EP-415), and with the voltage internally adjusted to give low-contrast and high-resolution images. Copies reduced by 66% were obtained directly from the herbarium specimens. We are now able to store digital images of the specimens in computer memory using a large flat-bed scanner (UMAX 2100 XL). After manipulating the images to lighten dark areas, we print high-resolution color reductions (Xerox Phaser 790) which are then bound, or we print to a CD. The following list is of currently available micro-herbaria and are mostly those created with the photocopier. Many others, not listed and now out of print, will become available as the specimens are scanned and printed on demand. To order or for more information, please contact RRC@fieldmuseum.org |
