them throughout the whole of the spring and summer months. Indeed, the species 
seems to blossom almost perpetually. 
Being at present scarce, and having only been kept in a stove for propagation,

succeed best in a stove through the early spring months, and then bloom better by 
being removed to the greenhouse, or to a structure intermediate between the two. 
It should be potted in a compost of light loam and heath-soil, and not be placed 
in too large a pot till it has acquired strength enough to demand greater freedom. 
It is increased by cuttings, which must be planted in sand, or a very sandy 
soil, and carefully guarded from superfluous moisture. 
The derivation of the generic title is siphon, a tube, and kampulos, curved ; the 
tube of the corolla being arched in a peculiar manner. The leaves of the species 
figured are thought to be like those of the birch ; hence the name betulwfolia.
