Field note. — Arctostaphylos drupacea, as observed on the summit of Monument Peak, La- 

 guna Mts., is noteworthy for its very large compact clusters of pink or rose-colored flowers which, 

 when in full bloom, form a gorgeous sight. It may be considered one of the finest shrubs of the 

 Southern California chaparral. When it goes into the fruiting stage, the berries are extremely 

 sticky. — F. W. Peirson.
