 cedar oil used for oil iinmei'sioii lenses, the aroma being 

 jjresent i]i the timbers, too. Home species of Dijsoxylon have 

 a disagreeable odour like that of onions and are, accordingly, 

 sometimes called "onionwood" by bushmen. The turnip- 

 Avcod {Alamia HiUii) has a stroii.u' odour of turnips. Panax 

 elegans, sometimes known as celery-wood, has a faint smell 

 of celery. Black bean (Castanospenniini a list rale) has a 

 pumpkin or cucaml)er-like smell. Species of the natural 

 order Laurinca' generally possess more or less fragrant 

 barks. The aroma of the l)ark and wood of red cedar is 

 often noticeable in the crushed green leaves, and is some- 

 times a useful means; of identifying them.
