ClNNAMOMUM. 



(Family Lauraceae). 



Small aromatic trees: ever- 

 green. Twigs terete, or com- 

 pressed at base, moderately stout 

 or those developed from buds of 

 the season slender: pith rather 

 large, continuous, white. Buds 

 solitary, ovoid, sessile or prompt- 

 ly developing so as to be stalked 

 for a time, small and either 

 naked or scaly, the terminal en- 

 larged and with more numerous 

 scales. Leaf-scars opposite or al- 

 ternate in 4 ranks, half-round, 

 somewhat raised: bundle-scar 1, 

 C-shaped : stipule-scars lacking. 

 Leaves simple, entire, stalked. 



The camphor tree has become 

 frequent as a street tree in south- 

 ern cities, where it thrives. 

 The true Malayan cinnamon ap- 

 pears to be scarcely hardy in the 



United States, but the Chinese cassia-bark tree (C. Cassia) 

 is said to stand frost and to be grown as a shade tree, and 

 also for its cinnamon-flavored bark, etc., in Florida, where, 

 as in southern California, several other species of the genus 

 are planted. 



Like many other genera which are confined to the tropics 

 today, Cinnamomum was wide-spread in northern latitudes 

 when circumpolar cold was less pronounced than it is now. 

 Buds scaly: leaves alternate: camphor-scented. 



(Camphor). (1). C. Camphora. 

 Buds naked: leaves opposite: cinnamon-scented. 



(Cinnamon). C. zeylanicum.
