to Eupatorium. Bentham says ‘‘Genus Kuhnice quam maxime 
affine.’’ Until these questions had been settled we might have 
been spared the synonymy. 
Llepharipappus 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 Layia 
which occurs on page 148 of Botany Beechey, 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. 
flazardia Greene of a single species amplified to three by 
the author, did not require the generic name. 
Evreminula 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 
Ludoviciana in the concluding sentence of Rafinesque’s de- 
scription of the fictitious 7roximon odoratum Raf. founded on 
Robin’s ‘ Chicoracée fenouillette’ and is as follows: ‘‘ This species 
together with 7+. virginicum, Tr. pallidum and Tr. bulbosum will 
form the genus Troximon, the other species which are acaules © 
and with an embricated [!] 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-
