This tree, which reaches a date of 20 to 30 feet, is endemic to the Hawaiian 
Islands, and is found on Oahu and Kauai. It develops a rather short trunk of 
about eight inches in diameter, and is vested in a whitish bark which is covered 
with lenticels. While all other known species of Sapindus have pinnate leaves, 
the Aulu or Lonomea is a remarkable exception, in having single, oblong, entire 
leaves, which never show any indication of division. 
The small, yellow flowers are arranged in long, terminal panicles, which 
are covered with a rusty-brown down. 
It is distinctly a tree of the lower forest zone, and inhabits the leeward sides 
of the Islands of Oahu and Kauai. On the former island it is found in the 
valleys of Makaha and Makaleha of the Kaala range, while a variety of it grows 
in the valley of Niu. On the latter island it is scattered on the lower levels at 
an elevation of 1000 feet back of Makaweli and Waimea, together with the 
Aleurites moluccana (Kukui), Ochrosia sandwicensis, Straussia, ete. 
he wood of the Aulu is whitish and of no value. On Kauai the seeds were 
used as a cathartic by the natives. A dose consisted of 7 to 8 seeds. 
The variety occurs in Nui Valley, on Oahu, but all the trees found in Nui by 
the writer were attacked very badly by a moth (Rhyiocoppha sp.?), which gave 
the trees an ungainly appearance; in fact, most of them were devoid of leaves.
