WILLIAM RUSSEL DUDLEY JORDAN 17 



health caused his retirement on the Carnegie Foundation, as professor 

 emeritus, his work being then taken by one of his students. Associate Pro- 

 fessor LeRoy Abrams. 



Many of the leading botanists of the country have been students • of 

 Professor Dudley. H. E. Copeland, Kellerman, Lazenby, Branner were 

 among his associates at Cornell. Atkinson became his successor at Cornell. 

 Abrams, Cook, Elmer, Olssen-Sefler, Cannon, Wight, E. B. Copeland, 

 E. G. Dudley, Greeley, Herre, McMurphy and many others were under his 

 tutelage at Stanford. 



In Stanford University, Dudley was one of the most respected as well 

 as best beloved members of the faculty. No one could come near to him 

 without recognizing the extreme refinement of his nature; a keen intellect, 

 an untiring joy in his chosen work, and the Puritan conscience at its best, 

 with clear perceptions of his own duties to himself and a generous recogni- 

 tion of the rights and the aspirations of others. 



Dudley entered with great joy into the study of the California flora. 

 He became especially interested in the study of trees, the evolutionary 

 relations of forms and especially the problems of geographical distribution. 

 The conifers of California were his special delight, and he made many 

 field trips with his students to all parts of the state, notably to the Sierra 

 Nevada and the Sierra Santa Lucia. His extended collections were presented 

 to Stanford University, where with the collections of Dr. Abrams they form 

 the major part of the large "Dudley Herbariiun." 



A genus of stone-crops, of many species, abounding on the cliffs of 

 California and especially on those which overhang the sea, was named 

 Dudleya by Britton and Rose. Dudleya pulverulenta is one of the most 

 conspicuous plants in California wherever ''sea and mountain meet." 



Dudley was. instrimiental in inducing the State of California to pur- 

 chase a forest of redwoods {Sequoia sempervirens) , that this, the second 

 of California's giant trees, might be preserved in a state of nature. Two 

 thousand five hundred acres in the "Big Basin" of Santa Cruz county were 

 thus bought and established as the "Sempervirens Park." For several years 

 Dudley served on the board of control of this park. 



Of the Sierra Club of California, Dudley was a leading member and 

 for some years a director. 



As an investigator. Professor Dudley was persistent and accurate, doing 

 his work for the love of it. A partial list of his papers is given below. A 

 large work on the conifers of the west was long projected, but still exists 

 only in uncompleted manuscript.
