268 OBSERVATIONS ON THE 
I should have preferred, inasmuch as his Z. palustris, growing in 
preference near the coasts, its name might lead us into error, since it 
would seem to belong with greater propriety to the other species. 
The name of this latter rests on a character very difficult to be seen ; 
put I do not conceive that these inconveniences are of sufficient im- 
portance to warrant the introduction of new names. 
In the following synopsis I shall cite few authors, because it is 
rarely possible to ascertain what species they are speaking of, though 
in general the locality is a tolerably good guide, but must not be de- 
pended on entirely; since the Z. palustris, according to Micheli, 
grows in the environs of Florence, and M. de Boenninghausen says 
of sepens, “in fossis turfosis precipue salsis.”
