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.
