two feet high, with spreading branches. Thrives best 

 in peat soil, or peat and loam. 



PITTQSPORUM. Banks. 



PITTOSPORUM TOBIRA. Alton. 

 (Tobira Pittosporum.) 



Although this handsome evergreen shrub will succeed 

 as a standard in the most favoured parts of the 

 country, it is best adapted for a wall. Height gene- 

 rally about six feet. Flowers cream-coloured, which 

 are produced in April. Leaves dark glossy green. 

 Thrives well in ordinary soil if dry and healthy. 



PITTOSPORUM UNDULATUM. 

 (Undulated-leaved Pittosporum.) 



Quite distinct from the preceding, and equally 

 hardy ; except in a few situations it is much better 

 treated as a wall plant, in which position it is very 

 ornamental, producing in summer a profusion of cream- 

 coloured flowers, which contrast beautifully with the 

 deep green of its foliage. 



POLYGALA. 



POLYGALA CHAM^IBUXUS. Linnaws. 



(Dwarf Box-leaved Polygala.) 

 A neat little plant, seldom growing above six inches
