to make nomenclature really stable is by an unfailing adher- 

 ence to a rule. If one exception is adnaitted another ivill be, 

 and as long as the human mind is active there will be botan- 

 ists who will think that they can secure notoriety for them- 

 selves by changing names and by making other deviations. 

 To prevent this and to make nomenclature stable, it seems to 

 us that the law of priority must be maintained at any cost of 

 labor and inconvenience, and that the longer its adoption is 

 postponed by makeshifts like the one here suggested and by 

 efforts to avoid meeting the issue squarely, the greater will be 

 the ultimate confusion, and we deplore any effort to postpone 

 changes of names which^ sooner or later, are sure to be made, 

 and every attempt to avoid compliance with the fundamental 

 law on which scientific nomenclature is based ^*'

 Cavanilles published it as an Aster, from specimens grown in
