This very ornamental greenhouse plant is a native of New Holland, found 
plentifully on the east coast. It grows to a large size, sometimes as much as ten 
or fifteen feet high, and branched in proportion ; a plant of even half that size when 
in full bloom is a most lovely obj'ect, for the spikes of flowers are generally very 
numerous, and being yellow they make an elegant contrast with the ample green 
pendant foliage. It is not so well adapted for a greenhouse, except the house be 
spacious and lofty, as for the conservatory, where it can be planted in a border, 
and plenty of room allowed for its roots to ramify and its branches to flourish. It 
grows best in open soil composed of strong loam and peat. It propagates easily 
from cuttings or from seeds. 
The sample for the drawing was most kindly furnished by our esteemed friend 
Mr. Cameron, of the Birmingham Botanic Garden, a short time back. 
This is a most interesting and beautiful genus of hardy greenhouse plants, produc- 
ing their flowers for the greater part in the spring months, when comparatively few 
plants besides are in a state of flowering. No collection should be without the following 
species, all of which are very fine and beautiful flowerers, and of easy cultivation.
