Background and Purpose:  Botanical science is one of the bases of pharmacy and pharmacology. Because of Mongol conquest of Khwarezmia and crusades, important social and political changes were happened in Islamic territory during 7th century A.H. However, few investigations were done on botanical works of this period of time. The aim of this study was to introduce these works.
Methods and Materials:  This library research was done by extracting botanical compilation and translation works from selected bibliographic resources.
Results:  The results showed that 61 botanical books and treaties were written in 7th century A.H. Among these works, only 45 of them have one or more physical manuscripts.
Conclusion:  In spite of social and political adversities, it seems that scientists of 7th century A.H. actively investigated on botanical topics which their activities were reflected in the number of botanical books and treaties written in this era. Historical evidences now show that most of these works are original.
