it, he was le<i to undertake the preparation of its "sequel," the 

 Flora Telluriana, dealing with the plants of the rest of the world. 

 The pages of these two works contain many descriptions of " new 

 genera" of plants, so that the dates of their appearance are of 

 considerable importance. As the books themselves are quite 

 scarce, a brief preliminary account of them may not be out of 

 place. 



Each was planned to consist of six " parts " or volumes, but 

 was completed in four. Each of the eight parts is separately 

 paged, and has a separate title-page and subtitle of its own ; and 

 each is dated " 1836."

 first to appear. It contained a dedication dated at Philadelphia, 

 September, 1836; and pages 73-80 are occupied by a mono- 

 graph of the genus Kii/uiia, dated October, 1836. These facts 

 alone are sufficient to make one suspect that perhaps the eight 

 parts were not all issued before the end of that year ! There is 

 not lacking other internal evidence on this subject, in addition to 

 the citation of Gray's monograph (Fl. Tell. 4 : 27 ; also New Fl. 

 4 : 103, where the date of " Grey's " paper is distinctly stated as 

 " 1837"). Flora Telluriana, part 3 (which in turn is cited by
