are not recorded in any save the most recent books on botany and gar- 
dening. As these new names are however now fixed for us and must sooner 
or later become generally known, we may as well learn them as rapidly 
as we can, and let us hope that nurserymen will adopt them soon. If you 
have not a copy of Bailey’s Standard Cyclopedia to consult, or some list 
that gives these latest changes in plant names, you will have a hard time 
getting some of these plants from dealers if you ask for them under their 
new names. Fortunately for us, these changes are not many nor difficult 
toremember. The most important for garden planners to know are: 
Virginia creeper and Boston ivy are no longer Ampelopsis but Par- 
thenocissus. 
Azalea becomes Rhododendron with the specific names little changed. 
The evergreen barberries with compound foliage are now Mahonia. 
The common trumpet creeper has been taken from Bignonia to Camp- 
SIS. 
The Japanese quinces are now Chenomeles, leaving the quince tree 
alone as Cydonia. 
Euonymus is now spelled Evonymus, and the specific names that were 
formerly in us now end in a. 
The day lilies known as Funkia are now listed under Hosta. 
The hickories are to take permanently the generic name of Carya. 
The apples, both the crabapples and the orchard forms, take the 
generic name of Malus, and only the pears are to be known as Pyrus. 
The smoke bush and its American relative are taken from Rhus and 
form the genus Cotinus. 
The chokeberries are taken from Sorbus and form the genus Aronia; 
the mountain ashes alone are in Sorbus. 
Many other lesser changes have been made, particularly in the specific 
names, but usually something in the new name will give the reader a clue 
to the identity of the plant.
