CLASSIFICATION OF ANGIOSPERMS. 279 



-mon (bark) is also obtained from Cassia Burmanni. Saigon cin- 

 namon (p. 513) is derived apparently from wild trees growing in 

 the mountainous regions of Anam, the botanical origin of which 

 has not been determined. 



- " The volatile oils of the members of the Lauracese vary con- 

 'siderably in composition. In addition to the oils of Sassafras 

 and Cinnamon the following may be mentioned : A cinneol- 

 containing oil is found in Cinnamomum Oliveri of. Australia, 

 Umbellularia calif arnica of Western North America and Laurus 

 nobilis the noble laurel of the Mediterranean and Mexico. A bor- 

 NEOL-containing oil is obtained from the root of Dicypcllium caryo- 

 phyllatum of Guiana, the wood of which is known in Cayenne as 

 rose-wood. An oil containing a notable amount of methyl sali- 

 cylate is obtained froni the' spice-bush (Lindera Benaoin) of the 

 United .States. 



Cinnamomum Camphora, or the camphor tree, is indigenous to 

 China, Japan and Formosa, and is now cultivated in many warm 

 countries as a shade and ornamental tree, growing very well in 

 Southern California and the Southeastern States. All parts of 

 the tree contain a volatile oil which on oxidation yields camphor 

 which latter is obtained by distillation and sublimation. Camphor 

 of poor quality is obtained from C. Parthenoxylon of Burmah, 

 Malaya and China, and C. glanduliferum of the Himalayas. Cam- 

 phor is also a constituent of other ethereal oils of this same family, 

 as the Massoy bark oil obtained from the root bark of C. seylan- 

 icuni and C. Burmanni of Java. 



A EUGENOL-containing volatile oil is obtained from Ravensara 

 aromatica of Madagascar, and Machilus Thunbergii of Japan. 

 Eiigenol is also found in oil of laurel leaves (L. nobilis), Massoy 

 bark oil, the oil of the leaves of Ceylon cinnamon, and the oils 

 obtained from Cimtamomum Culilawan of the Malay Peninsula 

 and China, and C. Wightii of East India, and possibly is also 

 found in Dicypellium caryophyllatum. 



The wood and the bark of Nectandra or Beeberu {Nectandra 

 ■Rodicei) of Guiana and Brazil contain several alkaloids, one^of 

 which is known as bebeerine and is supposed to be identical with 

 the alkaloids in Buxus sempervirens (Fam. Buxacese) ; pelosine 

 lound in Pareira; and paricine found in the bark of the. cultivated
