I 6 MEYER 



Sidney Fay Blake, for his scholarly contributions to the taxonomy of the 

 Compositae and other vascular plants and to our knowledge of the 

 floras of the world. 



Emma Lucy Braun, for her contribution to our knowledge of the origin and 

 structure of the Eastern American deciduous forest. Her critical evalua- 

 tion of the works of others, her capacity to observe correctly in the field 

 and to interpret forcefully have given biogeographers a new point of 

 departure. 



Stanley Adair Cain, whose sensitive perception of complex environmental 

 problems and intimate understanding of conflicting points of view have 

 provided us with many new insights. His courage in opening up new areas 

 has made him an outstanding interpreter and a leader of men. 



Ralph Works Chaney, for his notable achievements in paleobotany, which 

 have so greatly enriched our knowledge of the Tertiary floras. 



Agnes Chase, one of the world's outstanding agrostologists and preeminent 

 among American students in this field. 



Jens Christian Clausen, for his work toward the improvement of our un- 

 derstanding of the nature and origin of plant species. 



Ralph Erskine Cleland, for his extensive researches into the species rela- 

 tionships and segmental-interchange problems in Oenothera and also for 

 his statesmanship in representing plant science at the national level. 



Henry Shoemaker Conard, taxonomist, morphologist, mycologist, ecologist, 

 bryologist, shining proof that versatility may serve only to multiply ex- 

 cellences, and above all a beloved teacher. 



William Skinner Cooper, one of the creators of an American tradition in 

 ecology. His deep feeling for the relatedness and parallel developments 

 of geology, physiology, taxonomy, and vegetation science has been a 

 guiding light to a whole generation. 



John Nathaniel Couch, whose studies of the small, the intricate, and the 

 odd among fungi and their relatives have come to fructification in the 

 vivid, the significant, and the delectable. 



Bernard Ogilvie Dodge, whose perceptive researches into the taxonomy, 

 evolution, and pathological relations of the fungi have not been sur- 

 passed, but only overshadowed, by his discovery and exploitation of 

 Neurospora as a principal source of genetical truth. 



Benjamin Minge Duggar, for his outstanding researches in plant physiology, 

 plant pathology, and mycology for over half a century and for his wise 

 and patient counseling to many students for whom he provided inspira- 

 tion, imagination, and high standards of scholarship. 



Arthur Johnson Eames, plant anatomist and morphologist, for his sustained 

 researches on the morphology and anatomy of vascular plants and for 

 his noteworthy contributions to our knowledge of floral development and 

 evolution.
