The name of M. Gaillardia, a French gentleman 
of Charrentonneau, was chosen to represent this 
genus. Some botanists, doubting this individual’s 
claim to such distinction, have called it Virgilia he- 
lioides. It is better known by the former appella- 
tion; and a name once adopted, should exhibit 
stronger grounds of impropriety, than appears in 
the present instance, before a change be admitted. 
The botanist needs but a distinct term to represent 
a family of plants ; though certain it is, that if an 
appellation, indicative of a property or peculiarity, 
common to all the individuals of such family, could 
be adopted, very evident advantages would result 
from such nomenclature. 
The trivial name bicolor, given to this species, is 
borrowed from the Latin, in allusion to its flowers 
being two-coloured. Some varieties will be met 
with which show two colours more distinctly than 
ours, by their having an orange-red circle round 
the bottom of the petals. 
This beautiful plant may be increased by a divi- 
sion of its roots, or by seeds. It should be planted 
in a rich soil, and warm situation.
