get any -water at the roots during December and 
January. At the same time, if I saw that the 
plant was suffering for the want of water, I would 
not hesitate to give it some. The spraying can 
also be dispensed with during the resting period, 
but if the mealy bug appears, start spraying 
immediately. 
There are seven species of allamanda that are 
worthy of cultivation, and each one has its own 
merits. For the value of its cut blooms Allaman- 
da nobilis leads. Its blooms are four to five 
inches across, and the plant itself is a very rank 
grower, often attaining a height of forty feet. 
The two more commonly grown species, Schottii 
and Hendersoni, are almost identical, the differ- 
ence being merely that the throat of the flower 
of Schottii is darker than the other part of the 
flower, while in Hendersoni the throat is lighter, 
and there is a slight purplish tinge on the outside 
of the flower. Both vines will attain a height 
of thirty feet. 
The best allamanda for training as a bush 
specimen is 4. Williamsi, a very free-flowering, 
comparatively dwarf-growing plant. It is gener- 
ally used as a pot specimen. The remaining 
useful species are 4. cathartica, A. nertfolia and 
A. grandiflora.
