"Had a very pleasant letter from Mr. liicknell; and one de- 

 manding a prompt answer, and answered it. 



"Responded to a cjuerry on the part of Mr. Maxon as to the 

 value of such a character as that of perfectly articulated and 

 therefore deciduous pinnae in the frond of a fern supposed, and 

 commonly accepted, to be of the same genus in which the j^innae 

 are never deciduous, nor furnished with a distinct articulation. 

 My answer was, an opinion somewhat impromptu, that the 

 two kinds of fronds ought not to be embraced within one genus, 

 no matter how much alike in other particulars. 



"August 6. Studied Cichoriaceae as to their history in 

 taxonomy; especially as to the long admitted affinity for Cam- 

 panulaceae, which idea I fail to trace to any earlier original than 

 Jussieu. Such studies consume much time; and this whole day 

 was divided between this work and some correspondence. 



"August 8. Worked in the morning at study of the difficult 

 problem of Eschscholtzia Doiiglasii; with conclusion that the 

 Californian plants of that name in my Fl. Franciscana etc., are 

 different from the Oregonian. Spent afternoon at University, 

 searching for manuscript, book-packing, etc. Left some Leaflets 

 copy with printer. 



"August 9. Finished paper on New Apocynums for Leaflets, 

 and made progress on the Affinities of the Cichoriaceae. 



"August 10 and 11. Worked on title aforenamed. 



"August 12. Worked on Eschscholtzia, defining E. Doiiglasii 

 anew, and restricting it to the Oregonian plant. Had a pleasant 

 visit from Mr. O. F. Cook, lately back from Guatemala. At 

 University in the afternoon packing. 



"August 13. Further work upon Eschscholtzia; establishing 

 a little doubtfully the identity of my unpublished E. conuita 

 with E. ciiciillata. 



"Determined Californian Lupini for C. F. Baker. 



"August 17. Finished affinities of Cichoriaceae and took to 

 printer. 



"August 18. Received proofs. 



"August 19. Read proofs of 'Leaflets' and returned them. 

 Determined Calif, plants for C. F. Baker. Worked a little on
