to Eupatorium. Bentham says " Genus Kuhniae quam maxime 

 afl&ne." Until these questions had been settled we might have 

 been spared the synonymy. 



Blepharipappiis Hook. Fl. Bor-Am. i, 316, for Layia Bot, 

 Beech. 148. Mr. Greene gives the synonymy of this genus, 

 according to his idea, on page 245 of the second volume of 

 Pittonia. He there entirely overlooks the naming of I^ayia 

 which occurs on page 148 of Botany Beech ey, giving reference 

 only to the later page where it is found. It is possible that 

 Blepharipappus is a trifle earlier than Layia, but so far as we 

 now know the fact cannot be established. The volumes were 

 published so nearly at once and quote each from the other in so 

 irregular a manner that the internal evidence leaves the reader 

 in doubt. It is certain that page 142 of Botany Beechey was 

 printed before page 255 of Flor. Bor-Am., for the latter, there 

 quotes from the former. On the other hand it is equally apparent 

 that page 295 of Flor. Bor-Am. was printed before page 146 of 

 Bot. Beechey. On the whole it appears to have been entirely 

 unnecessary for Mr. Greene to transfer the species, even though 

 by so doing his name is made to follow all but one of the new 

 combinations. 



Hazardia Greene of a single species amplified to three by 

 the author, did not require the generic name. 



Ereminida Greene is substituted for Dimeresia Gray, because 

 of previous names, " Dimeria " "Dimesia" " Dimetia " and 

 " Dimeresa." Following such rule, Crockeria might be in dan- 

 ger from the earlier " Krockeria." 



Agoseris Raf. for Troximon Nutt. The attempt to bring this 

 name into use is an outrage. It occurs on page 58 of Flora 

 lyudoviciana in the concluding sentence of Rafinesque's de- 

 scription of the fictitious Troximon odoratum Raf. founded on 

 . Robin's ' Chicorade fenouillette' and is as follows: " This species 

 together with Tr. virginicnm, Tr. pallidum and Tr. bulbosiim will 

 form the genus Troximon, the other species which are acaules 

 and with an embricated [1] calyx must form a peculiar genus 

 which I shall call Agoseris." No type species is indicated and 

 no one can be certain of what plants Rafinesque had in that store-
