SIGNA Back issues

SIGNA back issues #1-100 are now available for download. Issues 1-80 are scans of originals or copies as were available. The scans were subsequently OCRed. The text in them can be searched, however they have not been proofed. There are a few mistakes, and a search could possibly miss something. The later issues are the original PDFs generated in Publisher and sent to e-members and are fully searchable. Also included is a draft Comprehensive index to issues 1-80. We are asking for a $40 donation for access to all these files. You can pay here now (includes a $1 PayPal fee) or contact Rodney Barton.

Paper copies of some back issues are still available from the publications manager. Contact our Publications Chair, molallagardens@outlook.com for details.

A NEW SYSTEM OF THE GENUS IRIS by Dr. George Rodionenko

This brand new publication tells of some of the early experiences of Dr. Rodionenko and his studies and observations of the Genus Iris in the wild for over 50 years. It not only offers a new insight into how the genus has expanded but gives the most in depth observances and history of Dr. Rodionenko himself. His conclusions will hopefully provoke a great deal of work on the part of other scientists.

This book sells for $9.95 plus shipping & handling.
