70 Writings of Edward L. Greene. [ZOE 
antedated as it quotes the London Journal of Botany for 1845 
and De Candolle’s, Prodromus, vol. ix, also of 1845. 
The two first were apparently printed nearly simultaneously. 
They alternately quote from each other beginning with the 
California part of Botany Beechey, and continuing in some- 
thing near the same order to the end. 
Mr. Greene adopts ostensibly the dates given in all the lists, 
1833 for the first volume of Flora Boreali-Americana; 1840 for 
the second volume and 1840 for the whole of Botany Beechey. 
The internal evidence shows that these two publications 
were printed in irregular parts or signatures at irregular intervals. 
Flora Boreali-Americana, is quoted in Don’s Dichl. Plants, com- 
mencing near the beginning of vol. i, dated 1831, and as Don’s 
volumes are of 700 or 800 4to pages, which, on account of the 
precision required, would take a long time to print, the evidence 
is sufficient to show that the first parts of Flora Bor.-Am. must 
have been printed, and to.a certain extent distributed early in 
1831. These books all followed the same classification, which 
interferes considerably with the definiteness of dates. Vol. i of 
Don quotes to Violacez: Vol. ii, 1832, quotes as far as its 
classification goes—page 214 of Flora Boreali being about the last. 
Flora Boreali-Americana commences on page 247 to quote 
Botany Beechey, page 124. 
In the light of these data the followin g dates affixed to the spe- 
cies by Mr. Greene will show how little he is to be trusted, and 
what a hopeless muddle he has made of the whole matter. They 
are copied unless otherwise stated from his Flora Franciscana.
