Welcome to the Digital Vasculum. A 'vasculum' is a tool shown in this photo that was used by botanists to keep plant specimens viable for study. They were collected in the field and brought back to a lab for further examination. Today's digital cameras, books, and computers have made it possible to take photos and identify flowers and plants later at home. Ziplock plastic bags have taken the place of the vasculum. I hope those interested in flowers and plants will find this a helpful tool for identification.
