HETEROMELES ARBUTIFOLIA Roem. 



The California toyon, or tollon, is a 

 handsome evergreen shrub found 

 throughout the state, better known as 

 the Christmas berry, or California hol- 

 ly. The scarlet berries are borne in the 

 greatest profusion, and, ripening at 

 Christmas time, are extensively used in 

 decorating. The berries are said to 

 liave formed an important article of 

 food with the Indians, and school chil- 

 dren frequently eat them: but, so far 

 as known, they are not otherwise util- 

 ized. They are not unpleasant to the 

 palate, having a healthy, bitterish by- 

 taste. The toyon is more useful as a 

 hedge plant, doubtless, than for its 

 fruit. It ranks high as an ornamental 

 evergreen, the dark foliage forming a 

 beautiful setting for the panicles of 

 white flowers. It appears in many 

 horticultural catalogues under the 

 name of Photinia arbutifolia.
