86 BOTANICAL GAZETTE [january 



time when he retired from active teaching in 1896, included the titles of 

 some 40 papers, which, with the exception of the four first numbers 

 written by himself, represent original w r ork accomplished by his students. 

 Among the latter were included B. D. Halsted, William Trelease, 

 J. E. Humphreys, W. A. Setchell, K. Miyabe, H. M. Richards, 

 and other well known names of American botanists. His own publica- 

 tions during this period were numerous, and included, for example, 

 " Monograph of the Gymnosporangia, " " Marine algae of New England, " 

 " Host index of fungi, " etc. It is greatly to be regretted that his magnum 

 opus, on selected species of fleshy fungi, for which an edition of very 

 beautiful plates was printed long before his death, has been left uncom- 

 pleted. 



Although he continued a member of the Harvard faculty until his 

 death, he withdrew from teaching in the year just mentioned, giving 

 attention occasionally to advanced students in whose work he felt a 

 special interest, devoting himself chiefly to the care and increase of the 

 herbarium and of his library, as well as to the supervision of the extensive 

 "Bibliographical index of American fungi," the first part of which, 

 prepared in collaboration with A. B. Seymour, was published by the 

 Carnegie Institution in 1905. At the same time he kept up his botanical 

 reading, about which he was hyperconscientious, and which was varied 

 and extensive, being by no means limited to matters relating to cryp- 

 togams alone; while he also carried on a voluminous correspondence, 

 sparing neither time nor trouble to assist those in search of advice or 

 information as to identities, synonymy, or literature. 



Throughout his life Dr. Farlow was an indefatigable collector, and 

 his activity of body and keen eyesight, which were little impaired by age, 

 combined w r ith his long experience and wide and exact knowledge, 

 enabled him to detect a host of new, rare, or interesting forms. His 

 annoyance at encountering unrecognizable, and in numberless instances 

 undoubtedly new, forms, was often very amusing. He had so little 

 patience with species makers that he himself described but a very small 

 percentage of the novelties that came in his way. Of those who make a 

 profession of this type of botanical activity he once said to his class, 

 "If a difference can be imagined , it is a new species; if one can be seen, 

 it is a new genus. " A number of new genera and species were none the 

 less named in his honor, of which he laughingly asserted that "they 

 were almost all bad." 



Dr. Farlow' s attainments, his rare ability and learning, commanded 

 the respect of all who came in contact with him, and were given recogni-
