which have already been mentioned, others being referable to 

 influences which have operated more recently, and still others 

 being somewhat incidental products of circumstance. Certain of 

 his diverse research concerns represent fields which he plowed 

 and later passed on for cultivation to colleagues and students. 

 Soon after coming to Berkeley, Setchell met Dr. H. W. Hark- 

 ness, President of the California Academy of Sciences, who had 

 long studied the subterranean or hypogaeous fungi, and who 

 desired assistance in preparing his observations for publication. 

 This incidental meeting revived Setchell's interest in the fungi 

 which had had its beginning in Farlow's laboratory, and as a 

 result he has been engaged for many years with the aid of 

 N. L. Gardner, Helen M. Gilkey, Lee Bonar, and H. E. Parks, 

 in assembling representative collections of California species. 

 Though the fungi herbarium and its study have been turned 

 over to Professor Bonar, these collections still enlist his interest. 

 Later on, in the Botanical Garden, of which he was Director 

 for many years, the possibility of growing for instruction and 

 display a collection of the commercial varieties of the tobacco 

 plant and other species of Nicotiana led to the obtaining of seed 

 from foreign as well as domestic sources. The early trials of this 

 seed indicated so much confusion with respect to nomenclature 

 that he began to give serious thought to the situation. Rather 

 extensive garden cultures soon produced a series of stable and 

 correcdy named species and varieties and, in addition, evidence 

 that the races of commercial tobacco represented hybrid com- 

 binations. For some years Setchell gave up his summers to an 

 analysis of varietal hybrids in Nicotiana Tabacum and to the re- 

 sults of hybridization among members of the collection of other 

 species which he now had available. From these early studies is 

 derived the extended research program dealing with the cyto-
