New Fl. 3 : 41, 51), on page 57 refers to Bot. Reg. //. igo6 (i 

 N 1836 !); and on page t^-j to Bot. Mag. //. 3540 (i D 1836 !), 

 which could not well have reached Philadelphia before the end 

 of the year 1836. Flora Telluriana, part 4 (which in turn is 

 cited by New Fl. 4 : 56, 57, 6^, 98), on page 124 cites Bot. Reg. 

 pi. igjS (i My 1837). But, in spite of these references, I know 

 of no internal evidence that the two works were not completed 

 before the end of the year 1837. 



From internal evidence, too, it is possible to arrange the parts 

 serially, in the order in which they were printed. This may be 

 done by means of the exact citations, by page, of one work by 

 the other; chiefly of the Flora Telluriana by the New Flora. 

 The result is as follows : New Fl. I ; Fl. Tell. I ; Fl. Tell. II ; 

 New Fl. II; Fl. Tell. Ill; New Fl. Ill; Fl. Tell. IV; New 

 Fl. IV. 



In order to approximate more closely than might otherwise be 

 possible the exact dates of issue of each of these parts, the series 

 of letters written to Torrey by Rafinesque during the years 

 1836 to 1839, and preserved in the Torrey correspondence at 

 the New York Botanical Garden, was searched, and the search 

 was well rewarded, as is shown by the following quotations : 



September 5, 1836. — "I having leisure have resolved to be- 

 gin to print my New flora of North Amer. by alphabetical 

 order. . . . When this Work is printed, my botanical labors 

 from 1802 to 1836, in America, will be better known." 



December 21, 1836. — "My flora proceeds very slowly & 

 was even suspended awhile for lack of a compositor that could 

 print Botanical terms ! . . , I have concluded to close the Lexi- 

 con of monographs very abruptly, and give instead selected 

 monographs & my N. Genera & species." 



This shows that only ten days before the close of the year 

 1836 even the printing of the first part of the New Flora was 

 not completed. 



April 18, 1837. — "I wanted to surprise you with a great 

 Botanical Work — my Flora telluriana ... to which I was led 

 by my New flora of N. Amer,, but I could only print 2 parts or 

 volumes. I. Classes & Orders. 2d. 400 N. Gen. my other 

 engagts have compelled me to suspend for a while."
