and planting the specimens in the border, to secure a greater quantity of finer 
cuttings for propagation, the plan, where it can be adopted, deserves imitation ; and 
a house so formed, filled with scarce and dwarf specimens, and varied with a few 
climbers which do not cover a large surface, would be a fine feature in any collection. 
To enliven the appearance of the interior, the sides of the walk need not be one 
continuous wall of brick, but the pit may be elevated on arches and pillars, as

Our subject, when grown in a pot, must have a very light and open earth, and 
should be particularly attended to in respect to water ; for its delicate roots 
speedily suffer from either a scarcity or a superfluity of moisture. It thrives well 
in an airy greenhouse, and though its main stem may sometimes require supporting 
by a stake, the branches should be permitted to assume their natural position, since 
they have a far more pleasing effect thus than when formally tied in an upright or 
any other posture. It is easily multiplied by cuttings. 
The species inhabits the district around Port Jackson, in New Holland. Our 
figure was made at Messrs. Rollisson's, at the period already specified. 
Mr. John Zier, described as a learned and industrious Polish botanist, who aided 
Mr. Dickson in preparing his work on Cryptogamia, is commemorated in the 
generic title.
