PITTOSPORUM (Greek, pitch seed; in allusion to 

 the resinous coating of the seeds). Pittospordcex. 

 Hardy or half-hardy evergreen woody plants grown 

 especially in California and Florida. Several species are 



excellent hedge plants, much preferred to privet and 

 box in some localities; many are useful ornamentals 

 for lawns and shrubberies; a few are used as avenue 

 trees; nearly all have fragrant flowers. 



Shrubs and trees: Ivs. simple, exstipulate, alternate or 

 apparently whorled: fls. regular, the parts in 5's; sepals 

 distinct or connate at base; petals distinct or lightly 

 united, tips often recurved; ovary incompletely 2-celled 

 (rarely 3-5-celled); style 1; stigma 1: fr. a globose, 

 ovate orobovate 

 caps., 2- to many- 

 seeded; valves 

 leathery or 

 woody. About 

 100 species, 

 chiefly of the 

 southern hemi- 

 sph ere and 

 largely Austra- 

 lian. 



Pittosporums 

 are usually prop- 

 a g a t e d by 

 seeds, which are 

 sown in winter 

 or early spring 

 hi ordinary soil 

 in the cool green- 

 house. Seeds do 

 not keep well 

 and those of the 

 rarer kinds are 

 difficult to pro- 

 cure; but all 

 species are 

 readily propa- 

 gated from cut- 

 tings of half- 

 ripened wood. 

 P. Tobira, which 

 seldom sets seeds, and its variety, which does not come 

 true, are also obtained in this manner. P. phittyraeoides 

 is best if grafted upon P. undulotum, since otherwise it 

 is liable to be crooked and branched. P. eriocarpum is 

 also grafted upon this stock. Seedlings should be repot- 

 ted from the seed-bed as soon as the second or third 

 leaf has formed.
