sipate (he confusion whicb had surrounded many others previously known. 



In 1838 he became associated with his preceptor, the distinguished botan- 

 ist Dr. John Torrey, in the publication and joint authorship of the Flora of 

 "North America," a work designed to give a brief description of all the 

 known indigenous and naturalized plants growing north of Mexico. The 

 abiding friendship which existed between these two great men is charly 

 shown and beautifully expressed in the dedication to Dr. Torrey : "almost 

 twenty years have passed since the first edition of this work was dedicated 

 to you — more than thirty year's since as your pupil, I began to enjoy the 

 advantages of being associated with you in botanical pursuits, and on a last- 

 ing friendship. The flow of time has only deepened the sense of grati- 

 tude to you from your attached friend." 



The Flora of North America was suspended at the end of the Compositae 

 (this latter order was arranged mainly through the labors of Dr. Gray. 

 The suspension was owing to various causes; chiefly to the new relations of 

 oiir government in the extension of our territories bj' the annexation of 

 Texas, the acquisition of California, and the Gadsden Purchase, which 

 brought about a change in the phytographical boundaries of our country. 

 Prof. Gray had resumed the revision of this work during his later years, 

 but has left it unfinished. The Gamopetalse being complete he was actively 

 engaged upon the first part of the Polypetalie just prior to his death. 



From my earliest acquaintance with him he seemed deeply impressed 

 with the importance of the botany of this coast. He made three visits to 

 the coast for the purpose of study as well as relaxation; in all his visits he 

 was accompanied by his devoted and loving wife, whose charming nature 

 was so adapted to his that she had become an inseparable companion in his 

 work as well as in his life. On his second visit he was associated with Sir 

 Joseph Hooker, England's great botanist, then of Kew Garden. 



Their visit was for the purpose of determining some occult point in rela- 

 tion to the Coniferai. In order to accomplish their object they left the 

 overland train at Eeno, Nevada, and proceeded by easy stages through Nevada 

 to the Calaveras Big Tree Grove, studying the habitat and all other peculiari- 

 ties of the Conifers of the Sierras in their course, thus familiarizing them- 

 selves with points not to be derived from any other source than nature's 

 own volume. 



In describing the plants of this Coasf, he has not failed to remember the 

 names of the botanists and collectors connected with this Academy, assign- 

 ing their names to new genera and species found in our State and adjoining 

 localities. Thus we have Kelloggia, a new genus of Eubiaceous plants. 

 Bolandera, Stanfordia, Lemmoiiia, Plummera, Lyonothamnus, Greenella, and 

 many others. 



With the botany of this coast his name will ever be most intimately as- 

 sociated, he having described and given names to many new genera and 

 species, both in the monographs published under the auspices of the govern- 

 ment and learned societies of the country, as well as the American Journal
