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.
