" Qnainasia cscitlcnta (K&r) Raf.," instead of entering Q. csciilciita 

 Raf. as a synonym of the western plant, as Coville has done. 



" Ri/h's )-i'siii()sinn Pursh " dates from the Botanical Magazine 

 {pi. ijSj. I S 1813) instead of from tiic Flora (page 163. 



1814). 



" Ooiotlicra Missourioisis Sims " (Bot. Mag. //. i ;ig2. i N 

 181 3) has priority over " Oenothera macrocarpa Pursh" (Fl. Am. 

 Sept. 734. 1 8 14). The name published by Pursh had been 

 used in 18 13 by Nuttall in Phraser's Catalogue, for what was 

 doubtless the same plant, but with a very brief characterization. 

 It is not unlikely, however, that 0. Missoiiricnsis and 0. macro- 

 carpa, treated as synonymous by all recent writers, are actually 

 distinct species. In this connection, a brief note published at 

 the end of the text accompanying plate 16"]^ of the Botanical 

 Magazine should not be overlooked. 



'' LopJiiola aurea Ker " (Bot. Mag. pi. ijgS. i N 181 3) has 

 priority over " Conostylis Americana Pursh " (Fl. Am. Sept. 224. 

 1 8 14), and the combination '' Lophiola Americana {Vurshy is 

 superfluous. Incidentally it may be mentioned that this binomial, 

 Lophiola Americana, published as new by Coville (Mem. Torrey 

 Club, 5: 118. 1894) and consequent!)' sometimes credited, to 

 him, was proposed by Wood nearly fifty years earlier (Class-book, 

 ed. 2, 540. 1848), and used by him in the various editions of 

 his Class-book during later years. 



" Sabbatia calycosa Pursh " dates from the Magazine [pi. 1600. 

 I D 181 3) instead of from the P^lora (page 138. 18 14). 



The date of publication of Pursh's Flora falls between that of 

 the 26th volume of Rees' Cyclopaedia and that of the 27th vol- 

 ume of the same work. In the Cyclopaedia, Smith's first refer- 

 ence to Pursh's work is in the second half of volume 27, under 

 the article " J^inns." Speaking of the number of species, he 

 says: "Mr. Pursh has nineteen in his P^lora of North America, 

 just come to our hands," and in discussing the different spe- 

 cies, Pursh's work is constantly referred to. As this part of the 

 Cyclopaedia appeared early in the year 18 14, the whole of the 

 two following volumes being issued before the end of the same 

 year (according to the researches of Mr. B. D. Jackson, see
