THE BAILEY-WETMORE LABORATORY OF 

 PLANT ANATOMY AND MORPHOLOGY 



In 1933, Professors Irving W. Bailey and Ralph H. Wetmore 

 of Harvard University decided to coordinate their future re- 

 search efforts in comparative plant anatomy and to pool their 

 botanical collections (mostly wood) with those of the late Pro- 

 fessor Edward C. Jeffrey. Professor Jeffrey had been interna- 

 tionally recognized for his technical skill and pioneering research 

 into the anatomy of vascular plants, which culminated in his 

 textbook, The Anatomy of Woody Plants (1917). Jeffrey also 

 had applied his extensive knowledge of paleobotany and plant 

 anatomy to the complex problem of the botanical and geological 

 origins of coal (Jeffrey, 1924). Later he expanded this into a 

 more popular but nevertheless comprehensive book entitled 

 Coal and Civilization (1925). 



Bailey and Wetmore, among other notable twentieth century 

 botanists, had studied plant anatomy with Jeffrey and shared his 

 conviction that comparative anatomy was a fundamental and 

 indispensable subdiscipline within the broad context of Plant 

 Biology. They therefore initiated a wood collection for the 

 Department of Biology (Wetmore, personal communication,
