Hawaii. Seeds collected by Mr. J. F. Rock, agri- 
cultural explorer. "Collected near Kilauea, Vol- 
cano House forests, Hawaii, April 12, 1921. A shrub 
15 feet in height, native to the mountains of Ha- 
waii, related to the ohelo berry (Vaeeinium retieulatum) , 
and covered with bright, cherrylike berries which 
are brilliant red for several months in the year. 
It grows at an altitude of about 4,000 to 5,000 
feet, and is especially abundant about the region 
of the volcano of Kilauea, The berry is less well 
known than the ohelo berry. Owing to the bright red 
color of the berries " they have been avoided for 
fear of their being poisonous. They are much juic- 
ier than the ohelo berries, but are slightly bit- 
ter; some, however, are sweet and delicious. The 
plant is peculiar to the Hawaiian Islands." (Rock.)
