The sword-shaped leaves of this genus gave 
occasion for the name, from the Latin gladius. 
Colvillii is adopted, as a distinction, after the pre- 
vailing fashion of nurserymen. 
This bulb originated in the nursery of Mr. 
Colvill, of King’s Road, Chelsea, from seeds of 
Gladiolus concolor, the flowers of which had been 
fertilized with the pollen of Gladiolus cardinalis. 
We have observed it in cultivation for nearly 
twenty years, and, although of hybrid origin, it 
appears to be permanent, and continues as healthy 
as any natural species. 
Sweet expresses a belief that the number of 
species of plants are daily increasing in the same 
manner, by natural means, as we increase them by 
artificial ones ; and, also, that hybridization is so 
far under our command, that it is only to consider 
what colours or markings may be advantageously 
mingled, and flowers of greater beauty than those 
of either of the parent species may be produced. 
Sweet was a practical cultivator, and acute observer, 
but his sanguine temperament required the modi- 
fication of true philosophy.
