STANDLEY TEEES AND SHRUBS OF MEXICO. 667 



The fruit is covered by a sweet waxy exudate which was used by some of 

 the Indians as a substitute for sugar. The flowers are said to yield a good 

 quality of honey. The flower clusters were boiled and eaten by the Coahuilla 

 Indians of California, and a decoction of the leaves was employed as a remedy 

 for coughs and for pains in the chest.
