We therefore suspect some mistake in the report that this 
is a native of Ceylon. 
It is a genuine species of Pharbitis, and by its entire cor- 
respondence in habit with the other species tends to confirm 
the propriety of maintaining that genus. 
It is a charming species when trained over a trellis in a 
pot, and more particularly when planted in the ground and 
led over the rafters of the greenhouse or cool stove. It evi- 
dently does not require a stove temperature, but like several: 
other Buenos Ayres plants, does best in a house which is 
kept rather higher than a common greenhouse. It forms 
large tuberous roots which should be kept nearly dry during 
the winter, when it is not growing. Before it begins to push 
in spring the stems should be thinned, and cut back some- 
thing in the way in which vines upon walls are treated; and 
at the same time if any insects are upon it they must be care- 
fully washed off, otherwise the white bug and scale will 
increase so fast as to render it unsightly when in flower. It 
is easily propagated by cuttings, and grows luxuriantly in 
any free soil.
