Ons. Printed names of plants shouid seldom be 
changed without apologys and never without a 
good reason. And perhaps, the only allowable 
reasonsare, when tbe name is erroneous through 
preoccupation; or where it misleads through 
some variance with truth. Such, for instance, 
as the calling a plant American, which is not 
indigenous to America ; an annual by a peren- 
nial name; or a flower yellow, when it is not 
of that colour. And hence the change of the 
preseut fulvous flowered species (beretófore 
called by us. stramineum) to fulvum, is allow- 
able. The error arose in Syn. succ. 9. 261, on 
our elevating two varieties, given as one species, 
into two species ; calling the horizontal-leaved 
straw-flowered one, Aorizontale; and leaving 
the other, though a fulvous-flowered one, in 
possession of the specifie name of mes amineum 
Meere (belotgimg: to another) was 
its rectification in the present jiliek sould. b be 
considered as an improvement.
