This rather handsome tree was first collected by Dr. H. L. Lyon in the woods 
of Nahiku, on the north-eastern slopes of Mt. Haleakala, Maui, at an elevation 
of 1300 feet. The species differs from the other Hawaiian Sideroxyla in the 
large black ovoid fruits and mainly in the very flat thin-beaked seeds. It grows 
in the rain forest of Nahiku, where precipitation is exceedingly heavy; while 
most of the other Hawaiian Sideroxyla are peculiar to the dry regions. When 
the writer visited the forests of Nahiku in the year 1911, the trees were neither 
in flower nor in fruit. The trees are not very abundant, but only individual 
trees could be seen scattered through the forest.
