PHARBITIS OSTRINA, 
long tube, and an undulated limb ; but their colour, which is a deep sanguine 
purple, is particularly rich. 
The species is readily cultivated ; requiring a rather nutritive loamy soil, and 
a moderately large pot. As it seems to flourish best in a warm moist stove, it is 
a favourable object for training over the roof of an Orchidaceous-house, where its 
leaves will afford some shade to the plants growing below them ; and for such a 
purpose it is rendered especially suitable by the annual decay of its stems. During 
winter, it ought, however, to be kept in a drier place ; for all tuberous-rooted 
plants bloom in a superior manner if they are kept thoroughly torpid for two or 
three of the coldest months of the year. It is not, probably, well adapted for 
training over a low circular trellis, though this method might be tried with propriety. 
Its multiplication is effected by cuttings, which should be taken off early in 
the season, that they may form sufficiently large tubers to prevent them from dying 
in the following winter. Extreme caution is necessary in regard to supplying the 
cuttings with moisture.
