Notes. 
1. Both lists thus reject Corydalis Vent. 1803. While the British botanists were 
taking up another name, it seems strange that they could not accept Capmotdes, which 
18 quite as well defined as any of the rest of Adanson’s genera, and of these they have 
: admitted a considerable number : A/eum, Arctostaphylos, Cicendia, Epipactis, Poly- 
Senatum, Mibora, Apera, for example. 
2. The Linnaen use of Vasturtium is confined to the first edition of his « Sys- 
tema,” published in 1735. He did not use it subsequently and it was only again taken 
up by R. Brown in 1812, Meanwhile Roripa had been published and well defined. 
The American rejection of Vasturtium is thus based on the Rochester agreement, 
adopted by the Genoa congress, and more recently approved by the Austro-German 
tanists, to begin generic nomenclature at 1753. 
3- Here, again the “starting-point” for generic names comes into consideration, 
and 4/sin. has precedence of place in the first edition of the “Species Plantarum,” both 
genera being recognized in that work. It appears possible to me that both. genera 
will again be recognized, Alsine for A. media and its relatives and Ste//aria for 
Such types as S. graminea. : 
4. Both lists thus reject Spergularia Presl, and Lepigonum Wahl. Tissa has
