Tasmania. Another half-hardy species, which bears, 

 even in a young state, an abundance of, rather small 

 whitish flowers. Light, rich soil should be used in their 

 culture. 



Planera, See Zelkova, 

 Polycarpa. See Idesia. 



Polygala (Polygaleae), 



Polygala charlesbuxus. — Bastard Box. A neat little 

 shrubby plant, about 6 inches high, with small ovate, 

 coriaceous leaves and fragrant yellow and cream flowers. 

 P. chamaebuxus purpureus differs in bearing rich reddish-

 of rock plants. They are natives of Europe (1658), and 

 grow best in vegetable mould.

 stems, and succeeds well in light loamy soil and in full 

 sunshine. For covering a pergola, old tree stump, or 

 unhealthy, thin-foliaged tree, it has, perhaps, no equal 

 amongst hardy climbers. 



P. multiflokum. — Japan and China, 1881. This grows 

 to 20 feet in height in one season, the stems being 

 slender, and reddish in colour, while the spreading panicles 

 of whitish flowers are produced in abundance. 



P. vACCiNiFOLrcM. — Himalaya, 1845. This is a sub-

 leaves and terminal spikes of bright rosy-red flowers 

 produced freely towards the end of summer. It is of
