Wigandia Californica, Hook. & Arn. Bot. Beech. p. 364, t. 88. Borders of the Lower Gila and 
on the mountains east of San Diego, California; Major Emory. Near Monterey and in other 
parts of California; Parry. A shrubby plant, commonly 3-5 feet high. The leaves are 
variable in breadth and toothing: one of the narrow-leaved forms being E. angustifolium, 
Nutt. The flowers are rather showy and of a light purplish-blue color. The plant has a strong 
terebinthine taste, and abounds in aresinous matter which sometimes exudes so copiously from the 
stalks and leaves that in drying, the specimens stick firmly to each other and to the paper. 
The natives of California make an infusion of the leaves and use it as a tonic. : 
EnropvorroN TOMENTOSUM, Benth. l. c. E. crassifolium, Benth. 1. с. Sandy fields around San 
Diego, June; Parry, T'hurber. "This is a taller species than the preceding, growing from 6-8; 
and sometimes even 10 feet high. Like that, itis variable in the form and toothing of the 
leaves, and we have no hesitation in uniting the two species of Bentham here quoted. We 
have specimens that are intermediate, and Dr. Parry informs me, that he has seen them in 
California passing into each other.
