white flowers. The juvenile form is quite different in leaf 

 and habit, and the same tree may be adult above and juvenile 

 below, so that it looks as if consisting of two different species. 



(23.) Persoonia toru (Toro). 



A handsome fairly hardy small tree, 15-30 ft. high, of 

 symmetrical form, with reddish-brown twigs and thick shining 

 long very narrow leaves 4-8 in. in length, which are rather 

 pale-green above, but purple or dotted with that colour beneath. 



(24.) The Species of Pittosporum. 



Pittosporum is an important genus in New Zealand, con- 

 taining about nineteen species some trees, others shrubs. The 

 most important of the trees are,- 



P. tenuifolium (syn. P. nigrescens) ; P. Colensoi ; P. fas- 

 ciculatum ; P. Buchanani (this and all the above species are 

 very closely related, and contain many distinct . forms difficult 

 to classify) ; P. Huttonianum ; P. patulum ; P. Dallii (not 

 yet in cultivation, but a splendid hardy tree with white sweet- 

 scented flowers) ; P. ellipticum ; P. Ralphii ; P. crassifolium ; 

 P. Fairchildii ; P. umbellatum ; and P. eugenioides. 



Several of the above are excellent for hedges, especially 

 P. tenuifolium, P. Colensoi, and P. Ralphii. P. crassifolium 

 can be grown close to the sea. P. eugenioides is most hand- 

 some with its shining elliptical leaves 2-4 in. long, their margins 

 wavy, and its compound umbels of small yellow flowers. 



P. obcordatum must now be almost the rarest wild plant in 

 the world, since but one or two trees are all that are known 

 to exist. It is not yet in cultivation. 



(25.) Pomaderris apetala (Tainui). 



A fairly hardy shrub or small tree, 20 ft. high, with 

 wrinkled oblong-ovate leaves 2-4 in. long, greyish beneath. 

 The species is of easy cultivation and fairly rapid growth. 



(26.) The Species of Pseudopanax. 



The genus is confined to New Zealand, and contains seven 

 species. P. crassifolium (hardy) and P. ferox (hardy) are 

 especially remarkable, in that the juvenile and adult forms are
