The Pepper, California Pepper or Peruvian Mastic (Schinus molle) was first 

 introduced into California from Peru by the early Spanish missions and is now 

 one of the most popular shade trees in many places south of San Francisco. It 

 is an irregular tree thirty to fifty feet in height and from two to four feet in 

 diameter. It suggests an apple tree with the drooping foliage of the willow. 

 There is a mass of slender branchlets, light fern-like foliage and long sprays of 

 red or rose tinted persistent berries the size of currants or pepper corns, whence 

 the name. The berries contrast with bright, evergreen leaves and render this one 

 of the most beautiful of all landscape trees. The leaves emit a pleasant, pungent 

 odor and possess, to some degree, the quality of stopping dust, which does not 

 however adhere to the leaves. There are gutta percha like exudations used in 

 medicine. The soft, smooth, whitish woods that sometimes darken with age are 

 not employed save for fuel. The pepper is the host of the " black scale " and is 

 1 eing replaced by the better, faster growing Longleaved Pepper (Schinus tere- 

 binthifolius) from Bra^il. Fourteen of the seventeen species are South American. 

 No one is important save as above. (Calif. Agricultural Exper. Station, Bui. 147.
